1. 启用Swagger

1.1 启用注解扫描和文档接口

直接在POM文件引入依赖

<dependency><groupId>io.springfox</groupId><artifactId>springfox-swagger2</artifactId><version>2.9.2</version>
</dependency>

1.2 启动swagger-ui

目前看到的选项有2个:

• swaager-ui ，访问地址: http://127.0.0.1:18080/swagger-ui.html

    <dependency><groupId>io.springfox</groupId><artifactId>springfox-swagger-ui</artifactId><version>2.9.2</version></dependency>

• swagger-bootstrap-ui ，也叫knife4j ，访问地址: http://127.0.0.1:18080/doc.html

    <dependency><groupId>com.github.xiaoymin</groupId><artifactId>swagger-bootstrap-ui</artifactId><version>${lastVersion}</version></dependency>

我更喜欢swagger-bootstrap-ui的风格

1.3 创建Swagger配置类

    @Configuration@EnableSwagger2public class SwaggerConfig {@Beanpublic Docket createRestApi() {return new Docket(DocumentationType.SWAGGER_2).apiInfo(apiInfo()).select()//                .apis(RequestHandlerSelectors.any()).apis(RequestHandlerSelectors.basePackage("com.dwpro")).paths(PathSelectors.any()).build();}private ApiInfo apiInfo() {return new ApiInfoBuilder().title("标题lws") //标题.description("简介lws") //简介.termsOfServiceUrl("服务条款lws") //服务条款.contact(new Contact("randy", "", "[e-mail]")).version("1.0.lws") //版本.build();}}

2. 注解

2.1 @Api

@Api注解在Controller上，通过tags指定指定名称(左侧菜单的名称)，tags可以指定多个值，多种使用场景通过指定相同的tag值将所有的API分组在一起。

@Api还有value和description属性，description已经@Deprecated，value号称会被当成tags值，实际测试下来无效

    @RestController@RequestMapping("/v1")@Api(tags = {"测试Swagger的注解使用"})public class HelloworldController {}

2.2 @ApiOperation

@ApiOperation用于注解到Controller上的方法，对应一个对外提供的接口。目前有4个属性:

属性	描述
value	对操作的简单说明
notes	对操作的详细说明
httpMethod	HTTP请求类型，可选:GET HEAD POST PUT DELETE OPTIONS PATCH
code	HTTP状态码，默认为200
produces	输出的Content-Type
consumes	输入的Content-Type

示例

    @RequestMapping("say")@ApiOperation(value = "用于打印用户输入信息", notes = "这是个什么鬼啊啊啊", httpMethod = "GET")public String say(@RequestParam("message") String message) {return message;}

2.3 @ApiParam

属性	描述
name	参数名称，因此这个一般应该是字母
value	参数说明
defaultValue	参数默认值
required	参数是否必须

参数类型会通过反射获取，如果参数是基本类型会显示在数据类型字段，如果参数是自定义的类，会同时显示在数据类型和schema字段

2.3.1 示例: query param

基本上只有value字段对接收说明有意义， example字段是在页面上调试给的示例值

@RequestMapping("say")
@ApiOperation(value = "用于打印用户输入信息", notes = "这是个什么鬼啊啊啊", httpMethod = "GET")
public String say(@ApiParam(value = "参数描述", example = "10086") @RequestParam("message") Integer message) {return "";
}

2.3.2 示例: 使用请求体，并用一个对象接收参数

使用@RequestBody的场景下，指定@ApiParam唯一有用的属性的value，指定其他参数没有效果

    @PostMapping("say2")@ApiOperation(value = "测试请求体", notes = "这是个什么鬼啊啊啊", httpMethod = "POST")public String say2(@ApiParam(value = "参数描述") @RequestBody ApFissionLog apFissionLog) {return "";}

2.4 @ApiImplicitParams 和 @ApiImplicitParam

和@ApiParam相同作用，但是不把注解混合到代码内部，可读性更强，个人更喜欢这种方式

    @PostMapping("say3")@ApiImplicitParams({@ApiImplicitParam(name = "cavatar",value = "value1",example = "10001", dataType = "int", paramType = "query"),@ApiImplicitParam(name = "cnickname",value = "value2",example = "example2", dataType = "string", paramType = "query")})public String say3(@RequestParam("cavatar") String cavatar, @RequestParam("cnickname") String cnickname) {return "";}

2.5 @ApiResponse

定义接口的返回值，示例中say4和say5方法的表现基本一致，没发现注解的特殊意义

属性	描述
code	HTTP状态码
message	状态码的文本描述
response	返回值的class
responseContainer	返回容器类型时使用，有效值: List Set Map

    @PostMapping("say4")public ApFissionLog say4(@RequestParam("cavatar") String cavatar, @RequestParam("cnickname") String cnickname) {return new ApFissionLog();}@PostMapping("say5")@ApiResponse(code = 200,message = "返回描述", response = ApFissionLog.class)public ApFissionLog say5(@RequestParam("cavatar") String cavatar, @RequestParam("cnickname") String cnickname) {return new ApFissionLog();}

2.6 @ApiModel和@ApiModelProperty

当请求和响应是POJO的时候特别有用，现实场景中这又是最常用的情况。

@ApiModel用于指定POJO类的描述，提供更可读的类型名称(这个个人觉得没用，直接展示现有类名挺好)。

属性	描述
value	model的别名，默认为类名
description	model的详细描述

@ApiModelProperty用于描述POJO里的字段

属性	描述
value	属性简短描述
example	属性的示例值
required	是否为必须值

    @PostMapping("say6")@ApiOperation(value = "测试请求体", notes = "这是个什么鬼啊啊啊", httpMethod = "POST")public ApFissionLog say6(@RequestBody ApFissionLog apFissionLog) {return new ApFissionLog();}

通过在ApFissionLog类上添加注解

@ApiModel(value = "model类名字", description = "描述信息")
public class ApFissionLog {@ApiModelProperty(value = "C用户的昵称", notes = "notes", example = "AAA-BBB-CCC", required = true)private String cnickname;@ApiModelProperty(value = "C用户的头像", notes = "notes", example = "http://www.aaa.com/avtar.png", required = true)private String cavatar;}

3. API分组

通过在Swagger的配置类里创建两个Docket对象，扫描不同的包就能完成分组

@Configuration
@EnableSwagger2
public class SwaggerConfig {@Bean("defaultApi")public Docket createRestApi() {return new Docket(DocumentationType.SWAGGER_2).apiInfo(apiInfo()).groupName("分组1").select()
//                .apis(RequestHandlerSelectors.any()).apis(RequestHandlerSelectors.basePackage("com.dwpro")).paths(PathSelectors.any()).build();}@Bean("groupApi")public Docket createGroupApi() {return new Docket(DocumentationType.SWAGGER_2).apiInfo(apiInfo()).groupName("分组2").select()
//                .apis(RequestHandlerSelectors.any()).apis(RequestHandlerSelectors.basePackage("com.dwpro")).paths(PathSelectors.any()).build();}private ApiInfo apiInfo() {return new ApiInfoBuilder().title("标题lws") //标题.description("简介lws") //简介.termsOfServiceUrl("服务条款lws") //服务条款.contact(new Contact("randy", "", "[e-mail]")).version("1.0.lws") //版本.build();}
}

4. 完整示例

//                .apis(RequestHandlerSelectors.any()).apis(RequestHandlerSelectors.basePackage("com.dwpro")).paths(PathSelectors.any()).build();}private ApiInfo apiInfo() {return new ApiInfoBuilder().title("标题lws") //标题.description("简介lws") //简介.termsOfServiceUrl("服务条款lws") //服务条款.contact(new Contact("randy", "", "[e-mail]")).version("1.0.lws") //版本.build();}
}
