若依解析（一）登录认证流程

JWT+SpringSecurity 6.X 实现登录

JWT token只包含uuid ,token 解析uuid，然后某个常量加UUID 从Redis缓存查询用户信息
流程图如下

感谢若依，感谢开源，能有这么好系统供我学习。

设计数据库，部门表，用户表，角色表，权限菜单表，用户角色表中间表，部门角色中间表，角色权限菜单表中间表

登录成功返回前端

{"msg": "操作成功","code": "200",//用户tokentoken:"XXXXX",//菜单权限"permissions": ["system:user:resetPwd","system:post:list","monitor:operlog:export","monitor:druid:list","system:menu:query","system:dept:remove","system:menu:list",..."tool:gen:edit"],//角色权限"roles": ["test2","test1"],//用户信息"user": {"createBy": "admin","createTime": "2024-11-28 10:06:12",}，//路由信息[{"name": "System","path": "/system","hidden": false,"redirect": "noRedirect","component": "Layout","alwaysShow": true,"meta": {"title": "系统管理","icon": "system","noCache": false,"link": null},"children": [{"name": "User","path": "user","hidden": false,"component": "system/user/index","meta": {"title": "用户管理","icon": "user","noCache": false,"link": null}},{"name": "Log","path": "log","hidden": false,"redirect": "noRedirect","component": "ParentView","alwaysShow": true,"meta": {"title": "日志管理","icon": "log","noCache": false,"link": null},"children": [{"name": "Operlog","path": "operlog","hidden": false,"component": "monitor/operlog/index","meta": {"title": "操作日志","icon": "form","noCache": false,"link": null}},{"name": "Logininfor","path": "logininfor","hidden": false,"component": "monitor/logininfor/index","meta": {"title": "登录日志","icon": "logininfor","noCache": false,"link": null}}]}]},{"name": "Tool","path": "/tool","hidden": false,"redirect": "noRedirect","component": "Layout","alwaysShow": true,"meta": {"title": "系统工具","icon": "tool","noCache": false,"link": null},"children": [{"name": "Build","path": "build","hidden": false,"component": "tool/build/index","meta": {"title": "表单构建","icon": "build","noCache": false,"link": null}},{"name": "Gen","path": "gen","hidden": false,"component": "tool/gen/index","meta": {"title": "代码生成","icon": "code","noCache": false,"link": null}},{"name": "Swagger","path": "swagger","hidden": false,"component": "tool/swagger/index","meta": {"title": "系统接口","icon": "swagger","noCache": false,"link": null}}]},{"name": "Http://ruoyi.vip","path": "http://ruoyi.vip","hidden": false,"component": "Layout","meta": {"title": "若依官网","icon": "guide","noCache": false,"link": "http://ruoyi.vip"}}]
}

所有实体的基类

/*** 实体基类**/
@Setter
@Getter
@ToString
public class BaseEntity 
{private static final long serialVersionUID = 1L;/** 搜索值 */private String searchValue;/** 创建者 */private String createBy;/** 创建时间 */@JsonFormat(pattern = "yyyy-MM-dd HH:mm:ss")private Date createTime;/** 更新者 */private String updateBy;/** 更新时间 */@JsonFormat(pattern = "yyyy-MM-dd HH:mm:ss")private Date updateTime;/** 备注 */@ApiModelProperty(value = "员工姓名",hidden = true)private String remark;/*** 更新数据**/@ApiModelProperty(value = "员工姓名",hidden = true)private boolean update;/*** 新增数据*/@ApiModelProperty(value = "员工姓名",hidden = true)private boolean add;/** 请求参数 */@JsonInclude(JsonInclude.Include.NON_EMPTY)@ApiModelProperty(value = "请求参数",hidden = true)private Map<String, Object> params;}

部门实体

/*** 部门表 sys_dept**/
@Setter
@Getter
@ToString
public class SysDept extends BaseEntity
{private static final long serialVersionUID = 1L;/** 部门ID */private Long deptId;/** 父部门ID */private Long parentId;/** 祖级列表 */private String ancestors;/** 部门名称 */private String deptName;/** 显示顺序 */private Integer orderNum;/** 负责人 */private String leader;/** 联系电话 */private String phone;/** 邮箱 */private String email;/** 部门状态:0正常,1停用 */private String status;/** 删除标志（0代表存在 2代表删除） */private String delFlag;/** 父部门名称 */private String parentName;/** 子部门 */private List<SysDept> children = new ArrayList<SysDept>();
}

用户实体包含角色集合，以及所属部门信息

/*** 用户对象 sys_user**/
@Setter
@Getter
@ToString
public class SysUser extends BaseEntity
{private static final long serialVersionUID = 1L;/** 用户ID */private Long userId;/** 部门ID */private Long deptId;/** 用户账号 */private String userName;/** 用户昵称 */private String nickName;/** 用户邮箱 */private String email;/** 手机号码 */private String phonenumber;/** 用户性别 */private String sex;/** 用户头像 */private String avatar;/** 密码 */private String password;/** 帐号状态（0正常 1停用） */private String status;/** 删除标志（0代表存在 2代表删除） */private String delFlag;/** 最后登录IP */private String loginIp;/** 最后登录时间 */private Date loginDate;/** 部门对象 */private SysDept dept;/** 角色对象 */private List<SysRole> roles;/** 角色组 */private Long[] roleIds;/** 岗位组 */private Long[] postIds;/** 角色ID */private Long roleId;}

角色实体包含权限按钮集合,每个按钮对应一个权限（system:user:add），所以角色还包含权限集合

/*** 角色表 sys_role**/
@Setter
@Getter
@ToString
public class SysRole extends BaseEntity
{private static final long serialVersionUID = 1L;/** 角色ID */private Long roleId;/** 角色名称 */private String roleName;/** 角色权限 */private String roleKey;/** 角色排序 */private Integer roleSort;/** 数据范围（1：所有数据权限；2：自定义数据权限；3：本部门数据权限；4：本部门及以下数据权限；5：仅本人数据权限） */private String dataScope;/** 菜单树选择项是否关联显示（ 0：父子不互相关联显示 1：父子互相关联显示） */private boolean menuCheckStrictly;/** 部门树选择项是否关联显示（0：父子不互相关联显示 1：父子互相关联显示 ） */private boolean deptCheckStrictly;/** 角色状态（0正常 1停用） */private String status;/** 删除标志（0代表存在 2代表删除） */private String delFlag;/** 用户是否存在此角色标识 默认不存在 */private boolean flag = false;/** 菜单组 */private Long[] menuIds;/** 部门组（数据权限） */private Long[] deptIds;/** 角色菜单权限 */private Set<String> permissions;}

按钮权限实体,一个按钮下面还有子菜单，所以还包含一个菜单集合

/*** 菜单权限表 sys_menu**/
@Setter
@Getter
@ToString
public class SysMenu extends BaseEntity
{private static final long serialVersionUID = 1L;/** 菜单ID */private Long menuId;/** 菜单名称 */private String menuName;/** 父菜单名称 */private String parentName;/** 父菜单ID */private Long parentId;/** 显示顺序 */private Integer orderNum;/** 路由地址 */private String path;/** 组件路径 */private String component;/** 路由参数 */private String query;/** 路由名称，默认和路由地址相同的驼峰格式（注意：因为vue3版本的router会删除名称相同路由，为避免名字的冲突，特殊情况可以自定义） */private String routeName;/** 是否为外链（0是 1否） */private String isFrame;/** 是否缓存（0缓存 1不缓存） */private String isCache;/** 类型（M目录 C菜单 F按钮） */private String menuType;/** 显示状态（0显示 1隐藏） */private String visible;/** 菜单状态（0正常 1停用） */private String status;/** 权限字符串 */private String perms;/** 菜单图标 */private String icon;/** 子菜单 */private List<SysMenu> children = new ArrayList<SysMenu>();}

登录用户省份鉴权实体，继承UserDetails来源于 spring security

这个用户包含数据库中用户信息，而用户信息又包含角色，而角色又包含权限菜单，所以这个自定义UserDetails实现类包含用户的所有信息

/*** 登录用户身份权限* */
@Setter
@Getter
@ToString
public class LoginUser implements UserDetails
{private static final long serialVersionUID = 1L;/*** 用户ID*/private Long userId;private String userName;/*** 部门ID*/private Long deptId;/*** 用户唯一标识*/private String token;/*** 登录时间*/private Long loginTime;/*** 过期时间*/private Long expireTime;/*** 登录IP地址*/private String ip;/*** 登录地点*/private String loginLocation;/*** 浏览器类型*/private String browser;/*** 操作系统*/private String os;/*** 权限列表*/private Set<String> permissions;/*** 用户信息*/private SysUser user;@JSONField(serialize = false)@Overridepublic String getPassword(){return user.getPassword();}@Overridepublic String getUsername(){return user.getUserName();}/*** 账户是否未过期,过期无法验证*/@JSONField(serialize = false)@Overridepublic boolean isAccountNonExpired(){return true;}/*** 指定用户是否解锁,锁定的用户无法进行身份验证* * @return*/@JSONField(serialize = false)@Overridepublic boolean isAccountNonLocked(){return true;}/*** 指示是否已过期的用户的凭据(密码),过期的凭据防止认证* * @return*/@JSONField(serialize = false)@Overridepublic boolean isCredentialsNonExpired(){return true;}/*** 是否可用 ,禁用的用户不能身份验证* * @return*/@JSONField(serialize = false)@Overridepublic boolean isEnabled(){return true;}@Overridepublic Collection<? extends GrantedAuthority> getAuthorities(){return null;}
}

导入spring-security 6.x 依赖

<dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-security</artifactId>
</dependency>

spring-security 上下文，上下文管理对象，用来在程序任何地方获取Authentication

/***  自定义 spring security 上下文管理类，管理Authentication对象**/
public class AuthenticationContextHolder
{//线程池保证线程传递同一个Authentication对象private static final ThreadLocal<Authentication> contextHolder = new ThreadLocal<>();public static Authentication getContext(){return contextHolder.get();}public static void setContext(Authentication context){contextHolder.set(context);}public static void clearContext(){contextHolder.remove();}
}

登录验证

/*** 登录验证** @param username 用户名* @param password 密码* @param code 验证码* @param uuid 唯一标识* @return 结果*/public String login(String username, String password, String code, String uuid){// 验证码校验validateCaptcha(username, code, uuid);// 登录前置校验loginPreCheck(username, password);// 用户验证Authentication authentication = null;try{//创建未认证令牌UsernamePasswordAuthenticationToken authenticationToken = new UsernamePasswordAuthenticationToken(username, password);AuthenticationContextHolder.setContext(authenticationToken);// 该方法会去调用UserDetailsServiceImpl.loadUserByUsername，真正通过用户名查询数据库，然后在比较密码//密码一致，将UserDetail 对象转换为Authentication 对象authentication = authenticationManager.authenticate(authenticationToken);}catch (Exception e){if (e instanceof BadCredentialsException){AsyncManager.me().execute(AsyncFactory.recordLogininfor(username, Constants.LOGIN_FAIL, MessageUtils.message("user.password.not.match")));throw new UserPasswordNotMatchException();}else{AsyncManager.me().execute(AsyncFactory.recordLogininfor(username, Constants.LOGIN_FAIL, e.getMessage()));throw new ServiceException(e.getMessage());}}finally{AuthenticationContextHolder.clearContext();}AsyncManager.me().execute(AsyncFactory.recordLogininfor(username, Constants.LOGIN_SUCCESS, MessageUtils.message("user.login.success")));LoginUser loginUser = (LoginUser) authentication.getPrincipal();recordLoginInfo(loginUser.getUserId());// 验证成功生成tokenreturn tokenService.createToken(loginUser);}

自定义UserDetailsServiceImpl，就是验证登录密码与从数据库中通过用户名查询的登录密码是否一致，一致的话再查询用户所有权限，

在把用户信息封装成UserDetail 返回

/*** 用户验证处理**/
@Service
public class UserDetailsServiceImpl implements UserDetailsService
{private static final Logger log = LoggerFactory.getLogger(UserDetailsServiceImpl.class);@Autowiredprivate ISysUserService userService;@Autowiredprivate SysPasswordService passwordService;@Autowiredprivate SysPermissionService permissionService;@Overridepublic UserDetails loadUserByUsername(String username) throws UsernameNotFoundException{SysUser user = userService.selectUserByUserName(username);if (StringUtils.isNull(user)){log.info("登录用户：{} 不存在.", username);throw new ServiceException(MessageUtils.message("user.not.exists"));}else if (UserStatus.DELETED.getCode().equals(user.getDelFlag())){log.info("登录用户：{} 已被删除.", username);throw new ServiceException(MessageUtils.message("user.password.delete"));}else if (UserStatus.DISABLE.getCode().equals(user.getStatus())){log.info("登录用户：{} 已被停用.", username);throw new ServiceException(MessageUtils.message("user.blocked"));}//验证登录密码与通过登录用户查询到的密码是否一致passwordService.validate(user);//密码验证成功，查询用户权限 ，将用户的所有信息封装成UserDetails 对象在返回return createLoginUser(user);}public UserDetails createLoginUser(SysUser user){//查询用户权限，返回 LoginUserreturn new LoginUser(user.getUserId(), user.getDeptId(), user, permissionService.getMenuPermission(user));}
}

查询用户权限

/*** 获得用户权限**/
@Component
public class SysPermissionService
{@Autowiredprivate ISysRoleService roleService;@Autowiredprivate ISysMenuService menuService;/*** 获取角色数据权限** @param user 用户信息* @return 角色权限信息*/public Set<String> getRolePermission(SysUser user){Set<String> roles = new HashSet<String>();// 管理员拥有所有权限if (user.isAdmin()){roles.add("admin");}else{roles.addAll(roleService.selectRolePermissionByUserId(user.getUserId()));}return roles;}/*** 获取菜单数据权限** @param user 用户信息* @return 菜单权限信息*/public Set<String> getMenuPermission(SysUser user){Set<String> perms = new HashSet<String>();// 管理员拥有所有权限if (user.isAdmin()){perms.add("*:*:*");}else{List<SysRole> roles = user.getRoles();if (!CollectionUtils.isEmpty(roles)){// 多角色设置permissions属性，以便数据权限匹配权限for (SysRole role : roles){if (StringUtils.equals(role.getStatus(), UserConstants.ROLE_NORMAL)){//通过角色获取角色下的菜单权限Set<String> rolePerms = menuService.selectMenuPermsByRoleId(role.getRoleId());role.setPermissions(rolePerms);perms.addAll(rolePerms);}}}else{perms.addAll(menuService.selectMenuPermsByUserId(user.getUserId()));}}return perms;}
}

登录密码验证

/*** 验证登录密码**/
@Component
public class SysPasswordService
{@Autowiredprivate RedisCache redisCache;//最大错误登录次数@Value(value = "${user.password.maxRetryCount}")private int maxRetryCount;//最大错误登录次数已满，固定时间才能重新登录@Value(value = "${user.password.lockTime}")private int lockTime;/*** 登录账户密码错误次数缓存键名** @param username 用户名* @return 缓存键key*/private String getCacheKey(String username){return CacheConstants.PWD_ERR_CNT_KEY + username;}public void validate(SysUser user){Authentication usernamePasswordAuthenticationToken = AuthenticationContextHolder.getContext();String username = usernamePasswordAuthenticationToken.getName();String password = usernamePasswordAuthenticationToken.getCredentials().toString();//获取用户名密码错误登录次数Integer retryCount = redisCache.getCacheObject(getCacheKey(username));if (retryCount == null){retryCount = 0;}//用户名密码错误登录次数 大于最大登录次数返回提示10分钟后登录if (retryCount >= Integer.valueOf(maxRetryCount).intValue()){throw new UserPasswordRetryLimitExceedException(maxRetryCount, lockTime);}if (!matches(user, password)){//错误登录失败次数+1，返回登录失败retryCount = retryCount + 1;redisCache.setCacheObject(getCacheKey(username), retryCount, lockTime, TimeUnit.MINUTES);throw new UserPasswordNotMatchException();}else{//登录成功，删除错误登录次数clearLoginRecordCache(username);}}public boolean matches(SysUser user, String rawPassword){//上下文中密码，与数据库中密码做比较return SecurityUtils.matchesPassword(rawPassword, user.getPassword());}//登录成功删除之前错误登录次数public void clearLoginRecordCache(String loginName){if (redisCache.hasKey(getCacheKey(loginName))){redisCache.deleteObject(getCacheKey(loginName));}}
}

登录验证完成

创建随机uuid，赋值loginUser.token

常量+uuid作为key,将用户信息保存redis

常量+uuid 加入JWTclaims, 创建加密后的JWT token

TokenService 类
/*** 创建令牌** @param loginUser 用户信息* @return 令牌*/public String createToken(LoginUser loginUser){//生成随机UUIDString token = IdUtils.fastUUID();loginUser.setToken(token);setUserAgent(loginUser);//常量+uuid作为key,将用户信息保存redisrefreshToken(loginUser);Map<String, Object> claims = new HashMap<>();claims.put(Constants.LOGIN_USER_KEY, token);//JWT,常量+UUID加密创建tokenreturn createToken(claims);}/*** 刷新令牌有效期,第一次就是保存** @param loginUser 登录信息*/public void refreshToken(LoginUser loginUser){loginUser.setLoginTime(System.currentTimeMillis());loginUser.setExpireTime(loginUser.getLoginTime() + expireTime * MILLIS_MINUTE);// 根据uuid将loginUser缓存String userKey = getTokenKey(loginUser.getToken());//某个常量加uuid 作为key,将用户信息保存redisredisCache.setCacheObject(userKey, loginUser, expireTime, TimeUnit.MINUTES);}/*** JWT从数据声明生成令牌** @param claims 数据声明* @return 令牌*/private String createToken(Map<String, Object> claims){String token = Jwts.builder().setClaims(claims).signWith(SignatureAlgorithm.HS512, secret).compact();return token;}

用户请求，被JwtAuthenticationTokenFilter过滤

/*** token过滤器 验证token有效性**/
@Component
public class JwtAuthenticationTokenFilter extends OncePerRequestFilter
{@Autowiredprivate TokenService tokenService;@Overrideprotected void doFilterInternal(HttpServletRequest request, HttpServletResponse response, FilterChain chain)throws ServletException, IOException{//从请求头中获得token,解析token，获得uuid,通过uuid 获得redis缓存中loginUser对象LoginUser loginUser = tokenService.getLoginUser(request);if (StringUtils.isNotNull(loginUser) && StringUtils.isNull(SecurityUtils.getAuthentication())){//验证token 失效时间，不足20分钟自动刷新tokenService.verifyToken(loginUser);//创建一个新的已认证令牌UsernamePasswordAuthenticationToken authenticationToken = new UsernamePasswordAuthenticationToken(loginUser, null, loginUser.getAuthorities());//设置已认证令牌的DetailsauthenticationToken.setDetails(new WebAuthenticationDetailsSource().buildDetails(request));//将已认证令牌设置到安全上下文SecurityContextHolder.getContext().setAuthentication(authenticationToken);}//请求转发给过滤器链下一个filter , 如果没有filter那就是请求的资源chain.doFilter(request, response);}
}

获得请求头里面token，TokenService类

	 /*** 获取用户身份信息** @return 用户信息*/public LoginUser getLoginUser(HttpServletRequest request){// 获取请求头中tokenString token = getToken(request);if (StringUtils.isNotEmpty(token)){try{Claims claims = parseToken(token);// 获得token中的uuidString uuid = (String) claims.get(Constants.LOGIN_USER_KEY);String userKey = getTokenKey(uuid);// 从缓存中获得LoginUser对象LoginUser user = redisCache.getCacheObject(userKey);return user;}catch (Exception e){log.error("获取用户信息异常'{}'", e.getMessage());}}return null;}/*** 获取请求token** @param request* @return token*/private String getToken(HttpServletRequest request){//从请求头中获取Authorization对应的值String token = request.getHeader(header);//判断请求头中是否有Authorization键值对，并且值以Bearer开头if (StringUtils.isNotEmpty(token) && token.startsWith(Constants.TOKEN_PREFIX)){//将Bearer替换为空串，获得真正的token值token = token.replace(Constants.TOKEN_PREFIX, "");}return token;}

退出操作，直接实现LogoutSuccessHandler ，然后加入到SecurityConfig 过滤链中

/*** 自定义退出处理类 返回成功* */
@Configuration
public class LogoutSuccessHandlerImpl implements LogoutSuccessHandler
{@Autowiredprivate TokenService tokenService;/*** 退出处理* * @return*/@Overridepublic void onLogoutSuccess(HttpServletRequest request, HttpServletResponse response, Authentication authentication)throws IOException, ServletException{LoginUser loginUser = tokenService.getLoginUser(request);if (StringUtils.isNotNull(loginUser)){String userName = loginUser.getUsername();// 删除用户缓存记录tokenService.delLoginUser(loginUser.getToken());// 记录用户退出日志AsyncManager.me().execute(AsyncFactory.recordLogininfor(userName, Constants.LOGOUT, MessageUtils.message("user.logout.success")));}ServletUtils.renderString(response, JSON.toJSONString(AjaxResult.success(MessageUtils.message("user.logout.success"))));}
}

定义权限上下文持有者，将参数放入RequestContextHolder，或者从RequestContextHolder取出，简单来说就是

属性与当前HTTP请求相关联的方法

/*** 权限信息* */
public class PermissionContextHolder
{private static final String PERMISSION_CONTEXT_ATTRIBUTES = "PERMISSION_CONTEXT";public static void setContext(String permission){RequestContextHolder.currentRequestAttributes().setAttribute(PERMISSION_CONTEXT_ATTRIBUTES, permission,RequestAttributes.SCOPE_REQUEST);}public static String getContext(){return Convert.toStr(RequestContextHolder.currentRequestAttributes().getAttribute(PERMISSION_CONTEXT_ATTRIBUTES,RequestAttributes.SCOPE_REQUEST));}
}

自定义权限注解，就是判断注解上权限值，与用户权限是否一致

/**自定义权限注解* * */
@Service("ss")
public class PermissionService
{/*** 验证用户是否具备某权限** @param permission 权限字符串* @return 用户是否具备某权限*/public boolean hasPermi(String permission){if (StringUtils.isEmpty(permission)){return false;}//从上下文文中获取登录对象LoginUser loginUser = SecurityUtils.getLoginUser();if (StringUtils.isNull(loginUser) || CollectionUtils.isEmpty(loginUser.getPermissions())){return false;}PermissionContextHolder.setContext(permission);//注解权限与用户权限做比较return hasPermissions(loginUser.getPermissions(), permission);}/*** 验证用户是否不具备某权限，与 hasPermi逻辑相反** @param permission 权限字符串* @return 用户是否不具备某权限*/public boolean lacksPermi(String permission){return hasPermi(permission) != true;}/*** 验证用户是否具有以下任意一个权限** @param permissions 以 PERMISSION_DELIMETER 为分隔符的权限列表* @return 用户是否具有以下任意一个权限*/public boolean hasAnyPermi(String permissions){if (StringUtils.isEmpty(permissions)){return false;}LoginUser loginUser = SecurityUtils.getLoginUser();if (StringUtils.isNull(loginUser) || CollectionUtils.isEmpty(loginUser.getPermissions())){return false;}PermissionContextHolder.setContext(permissions);Set<String> authorities = loginUser.getPermissions();for (String permission : permissions.split(Constants.PERMISSION_DELIMETER)){if (permission != null && hasPermissions(authorities, permission)){return true;}}return false;}/*** 判断用户是否拥有某个角色** @param role 角色字符串* @return 用户是否具备某角色*/public boolean hasRole(String role){if (StringUtils.isEmpty(role)){return false;}LoginUser loginUser = SecurityUtils.getLoginUser();if (StringUtils.isNull(loginUser) || CollectionUtils.isEmpty(loginUser.getUser().getRoles())){return false;}for (SysRole sysRole : loginUser.getUser().getRoles()){String roleKey = sysRole.getRoleKey();if (Constants.SUPER_ADMIN.equals(roleKey) || roleKey.equals(StringUtils.trim(role))){return true;}}return false;}/*** 验证用户是否不具备某角色，与 isRole逻辑相反。** @param role 角色名称* @return 用户是否不具备某角色*/public boolean lacksRole(String role){return hasRole(role) != true;}/*** 验证用户是否具有以下任意一个角色** @param roles 以 ROLE_NAMES_DELIMETER 为分隔符的角色列表* @return 用户是否具有以下任意一个角色*/public boolean hasAnyRoles(String roles){if (StringUtils.isEmpty(roles)){return false;}//从上下文中获取LoginUserLoginUser loginUser = SecurityUtils.getLoginUser();if (StringUtils.isNull(loginUser) || CollectionUtils.isEmpty(loginUser.getUser().getRoles())){return false;}for (String role : roles.split(Constants.ROLE_DELIMETER)){if (hasRole(role)){return true;}}return false;}/*** 判断是否包含权限** @param permissions 权限列表* @param permission 权限字符串* @return 用户是否具备某权限*/private boolean hasPermissions(Set<String> permissions, String permission){return permissions.contains(Constants.ALL_PERMISSION) || permissions.contains(StringUtils.trim(permission));}
}

自定义注解实现匿名访问

@Target({ ElementType.METHOD, ElementType.TYPE })
@Retention(RetentionPolicy.RUNTIME)
@Documented
public @interface Anonymous
{
}

注解匿名访问配置类,获得注解方法上的url

@Configuration
public class PermitAllUrlProperties implements InitializingBean, ApplicationContextAware
{private static final Pattern PATTERN = Pattern.compile("\\{(.*?)\\}");private ApplicationContext applicationContext;private List<String> urls = new ArrayList<>();public String ASTERISK = "*";@Overridepublic void afterPropertiesSet(){RequestMappingHandlerMapping mapping = applicationContext.getBean(RequestMappingHandlerMapping.class);Map<RequestMappingInfo, HandlerMethod> map = mapping.getHandlerMethods();map.keySet().forEach(info -> {HandlerMethod handlerMethod = map.get(info);// 获取方法上边的注解 替代path variable 为 *Anonymous method = AnnotationUtils.findAnnotation(handlerMethod.getMethod(), Anonymous.class);Optional.ofNullable(method).ifPresent(anonymous -> Objects.requireNonNull(info.getPatternsCondition().getPatterns()).forEach(url -> urls.add(RegExUtils.replaceAll(url, PATTERN, ASTERISK))));// 获取类上边的注解, 替代path variable 为 *Anonymous controller = AnnotationUtils.findAnnotation(handlerMethod.getBeanType(), Anonymous.class);Optional.ofNullable(controller).ifPresent(anonymous -> Objects.requireNonNull(info.getPatternsCondition().getPatterns()).forEach(url -> urls.add(RegExUtils.replaceAll(url, PATTERN, ASTERISK))));});}@Overridepublic void setApplicationContext(ApplicationContext context) throws BeansException{this.applicationContext = context;}public List<String> getUrls(){return urls;}public void setUrls(List<String> urls){this.urls = urls;}
}

使用注解

@PostMapping("/url")
@Anonymous()
public AjaxResult anonymouTest(){return AjaxResult.success("操作成功");
}

SpringSecurity 配置文件

//prePostEnabled = true 时，@PreAuthorize 用于在方法执行前进行权限检查，@PostAuthorize 用于在方法执行后进行权限检查。
//securedEnabled = true 时，@Secured 用于允许具有特定角色的用户访问。
@EnableMethodSecurity(prePostEnabled = true, securedEnabled = true)
@Configuration
public class SecurityConfig

}

注意：身份认证实现，这里配置了hash加密，前端是传明文密码。数据库存储加密后的密码。加入前端直接传密文，会提示错误

        daoAuthenticationProvider.setUserDetailsService(userDetailsService);daoAuthenticationProvider.setPasswordEncoder(bCryptPasswordEncoder());
