1.启动RabbitMQ

2.修改config服务端依赖：（boot和cloud版本不要太高，不然刷新配置的请求不能用）


<dependencies>
    <!--consul-->
    <dependency>
        <groupId>org.springframework.cloud</groupId>
        <artifactId>spring-cloud-starter-consul-discovery</artifactId>
    </dependency>
    <!--健康检查-->
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-actuator</artifactId>
    </dependency>
    <!--config-->
    <dependency>
        <groupId>org.springframework.cloud</groupId>
        <artifactId>spring-cloud-config-server</artifactId>
    </dependency>
    <!--bus-->
    <dependency>
        <groupId>org.springframework.cloud</groupId>
        <artifactId>spring-cloud-starter-bus-amqp</artifactId>
    </dependency>
    <!--web-->
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-web</artifactId>
    </dependency>
</dependencies>

配置：


spring:
  cloud:
    consul:
      host: localhost
      port: 8500
    config:
      server:
        git:
          uri: https://gitee.com/xiang_pei/config.git
          default-label: master
  application:
    name: CONFIGSERVER
  rabbitmq:
    host: localhost
    port: 5672
    username: guest
    password: guest
    virtual-host: /

#暴露所有端点，便于发送更新配置请求
management:
  endpoints:
    web:
      exposure:
        include: "*"

启动：（启动类加@EnableConfigServer）mq会有一条临时队列

3.修改微服务（即客户端）依赖：


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

    <dependency>
        <groupId>org.springframework.cloud</groupId>
        <artifactId>spring-cloud-starter-consul-discovery</artifactId>
    </dependency>

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

    <!--config client的依赖-->
    <dependency>
        <groupId>org.springframework.cloud</groupId>
        <artifactId>spring-cloud-starter-config</artifactId>
    </dependency>
    <!--重新导入bootstrap-->
    <dependency>
        <groupId>org.springframework.cloud</groupId>
        <artifactId>spring-cloud-starter-bootstrap</artifactId>
    </dependency>
    <!--bus-->
    <dependency>
        <groupId>org.springframework.cloud</groupId>
        <artifactId>spring-cloud-starter-bus-amqp</artifactId>
    </dependency>

</dependencies>

配置：不变（rabbitmq的配置应该写到gitee上）bootstrap.properties


spring.cloud.consul.host=localhost
spring.cloud.consul.port=8500
spring.application.name=CONFIGCLIENT

spring.cloud.config.discovery.service-id=CONFIGSERVER
spring.cloud.config.discovery.enabled=true


spring.cloud.config.name=config
spring.cloud.config.label=master
spring.cloud.config.profile=dev
