spring cloud config和bus组件实现自动刷新

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>
    
    <dependency>
        <groupId>org.springframework.cloudgroupId>
        <artifactId>spring-cloud-starter-consul-discoveryartifactId>
    dependency>
    
    <dependency>
        <groupId>org.springframework.bootgroupId>
        <artifactId>spring-boot-starter-actuatorartifactId>
    dependency>
    
    <dependency>
        <groupId>org.springframework.cloudgroupId>
        <artifactId>spring-cloud-config-serverartifactId>
    dependency>
    
    <dependency>
        <groupId>org.springframework.cloudgroupId>
        <artifactId>spring-cloud-starter-bus-amqpartifactId>
    dependency>
    
    <dependency>
        <groupId>org.springframework.bootgroupId>
        <artifactId>spring-boot-starter-webartifactId>
    dependency>

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.bootgroupId>
        <artifactId>spring-boot-starter-webartifactId>
    dependency>

    <dependency>
        <groupId>org.springframework.cloudgroupId>
        <artifactId>spring-cloud-starter-consul-discoveryartifactId>
    dependency>

    <dependency>
        <groupId>org.springframework.bootgroupId>
        <artifactId>spring-boot-starter-actuatorartifactId>
    dependency>

    
    <dependency>
        <groupId>org.springframework.cloudgroupId>
        <artifactId>spring-cloud-starter-configartifactId>
    dependency>
    
    <dependency>
        <groupId>org.springframework.cloudgroupId>
        <artifactId>spring-cloud-starter-bootstrapartifactId>
    dependency>
    
    <dependency>
        <groupId>org.springframework.cloudgroupId>
        <artifactId>spring-cloud-starter-bus-amqpartifactId>
    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

运行：

写了一个测试方法

name属性是gitee上的配置文件的name

没问题

4.利用webhooks实现自动刷新配置

向config服务端发送post请求

http://localhost:8080/actuator/bus-refresh

具体路径根据项目来

在gitee的config管理中，点击webhooks

url就填上面那个，因为需要公网才能测试，所以暂时不演示了。

设置完，改gitee的配置就会自动刷新了
