Springcloud-配置中心config

   一、添加依赖

<dependency><groupId>org.springframework.cloud</groupId><artifactId>spring-cloud-config-server</artifactId></dependency><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-actuator</artifactId></dependency>

  二、添加注解@EnableConfigServer

@SpringBootApplication
@EnableConfigServer
public class MainApplicationCenter3344 {public static void main(String[] args) {SpringApplication.run(MainApplicationCenter3344.class, args);}
}

  三、添加配置

server:port: 3344spring:application:name:  cloud-config-center #注册进Eureka服务器的微服务名cloud:config:server:git:uri: https://github.com/djftjfs/springcloud-config.git #GitHub上面的git仓库名字####搜索目录search-paths:- springcloud-configusername: xxxpassword: xxx####读取分支label: master#服务注册到eureka地址
eureka:client:service-url:defaultZone: http://localhost:7001/eureka

  四、测试http://config-3344.com:3344/master/config-dev.yml

  五、配置读取规则

    label : 分支名 ； application : 服务名 ； profile : 环境（dev/test/prod）

   /{label}/{application}-{profile}.yml

  eg：http://config-3344.com:3344/master/config-dev.yml

 /{application}-{profile}.yml

 eg：http://config-3344.com:3344/config-dev.yml

 /{application}/{profile}/{label}

 eg：http://config-3344.com:3344/config/dev/master

  四、客户端配置

   1、添加依赖

<dependency><groupId>org.springframework.cloud</groupId><artifactId>spring-cloud-starter-config</artifactId></dependency><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-actuator</artifactId></dependency>

   2、创建bootstrap.yml 配置文件

server:port: 3355spring:application:name: config-clientcloud:#Config客户端配置config:label: master #分支名称name: config #配置文件名称profile: dev #读取后缀名称   上述3个综合：master分支上config-dev.yml的配置文件被读取http://config-3344.com:3344/master/config-dev.ymluri: http://localhost:3344 #配置中心地址k#服务注册到eureka地址
eureka:client:service-url:defaultZone: http://localhost:7001/eureka

  五、动态刷新(手动)

        1、在客户端模块添加依赖

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

      2、在bootstrap.yml 文件添加如下内容

# 暴露监控端点
management:endpoints:web:exposure:include: "*"

     3、在业务类上添加@RefreshScope

@RestController
@RefreshScope
public class ConfigClientController
{@Value("${config.info}")private String configInfo;@GetMapping("/configInfo")public String getConfigInfo(){return configInfo;}
}

      4、手动刷新（必须post）

      执行 curl -X POST "http://localhost:3355/actuator/refresh"

  六、动态刷新（自动）

      1、在之前基础上在服务端和客户端上添加依赖

<!--添加消息总线RabbitMQ支持--><dependency><groupId>org.springframework.cloud</groupId><artifactId>spring-cloud-starter-bus-amqp</artifactId></dependency>

      2、服务端添加配置

#rabbitmq相关配置rabbitmq:host: 192.168.xxx.165port: 5672username: adminpassword: 123##rabbitmq相关配置,暴露bus刷新配置的端点
management:endpoints: #暴露bus刷新配置的端点web:exposure:include: 'bus-refresh'

     3、客户端只需添加RabbitMQIP相关配置即可

     4、当在git端修改完配置之后，只需在服务端执行curl -X POST "http://localhost:3344/actuator/bus-refresh" 即可刷新全部客户端

  七、精确刷新

       只需在上面通知上添加服务注册名及端口号即可

       curl -X POST "http://localhost:3344/actuator/bus-refresh/config-client:3355"
