SpringCloud Alibaba Bus（消息总线）

在SpringCloud config的基础上实现多台服务器修改，需要用到rabbitmq，git上的配置信息存到rabbitmq里面，git更新后更新到rabbitmq，客户端从rabbitmq里面取

服务端

pom

        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-bus-amqp</artifactId>
        </dependency>

yml

server:
  port: 3344

spring:
  application:
    name: cloud-config-center
  cloud:
  # 服务地址相关配置
    config:
      server:
        git:
          uri: git@github.com:leelovejava/springcloud-config.git
          search-paths:
            - spring-config
      label: master

eureka:
  client:
    service-url:
      defaultZone: http://eureka7001.com:7001/eureka

启动类

@SpringBootApplication
@EnableConfigServer  // 配置中心服务
public class ConfigCenterMain3344 {
    public static void main(String[] args) {
        SpringApplication.run(ConfigCenterMain3344.class, args);
    }
}

客户端

pom

        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-bus-amqp</artifactId>
        </dependency>

yml

server:
  port: 3355

spring:
  application:
    name: config-client
  cloud:
    config:
      label: master # 分支名称
      name: config #配置文件名称
      profile: dev # 读取的后缀，上述三个综合，为master分支上的config-dev.yml的配置文件被读取，http://config-3344.com:3344/master/config-dev.yml
      uri: http://config-3344.com:3344 #配置中心的地址
  rabbitmq: #rabbitmq相关配置，15672是web管理端口，5672是mq访问端口
    port: 5672
    host: localhost
    username: guest
    password: guest


eureka:
  client:
    service-url:
      defaultZone: http://eureka7001.com:7001/eureka

management:
  endpoints:
    web:
      exposure:
        include: "*"

启动类

@SpringBootApplication
@EnableEurekaClient
public class ConfigClientMain3355 {
    public static void main(String[] args) {
        SpringApplication.run(ConfigClientMain3355.class, args);
    }
}

方法类获取配置信息

@RestController
@RefreshScope
public class ConfigClientController {

    @Value("${config.info}")
    private String configInfo;

    @GetMapping("/configInfo")
    public String getConfigInfo(){
        return configInfo;
    }
}

全局通知修改：curl -X POST “http:/localhost:3344/actuator/bus-refresh”
指定服务修改：curl -X POST “http:/localhost:3344/actuator/bus-refresh/config-client:3355”

config-client：服务名称
