spring cloud config和bus组件实现自动刷新功能

今天通过本文给大家介绍spring cloud config和bus组件实现自动刷新功能，代码简单易懂，对大家的学习或工作具有一定的参考借鉴价值，需要的朋友参考下吧

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
