spring cloud config和bus組件實現自動刷新功能

Posted on by

1.啟動RabbitMQ

2.修改config服務端 依賴：（boot和cloud版本不要太高，不然刷新配置的請求不能用）

<dependencies>
    <!--consul-->
    <dependency>
        <groupId>org.springframework.cloud</groupId>
        <artifactId>spring-cloud-starter-consul-discovery</artifactId>
    </dependency>
    <!--健康檢查-->
    <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: /

#暴露所有端點，便於發送更新配置請求
management:
  endpoints:
    web:
      exposure:
        include: "*"

啟動：（啟動類加@EnableConfigServer）mq會有一條臨時隊列

3.修改微服務（即客戶端） 依賴：

<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的依賴-->
    <dependency>
        <groupId>org.springframework.cloud</groupId>
        <artifactId>spring-cloud-starter-config</artifactId>
    </dependency>
    <!--重新導入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：不變（rabbitmq的配置應該寫到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

運行：

寫瞭一個測試方法

name屬性是gitee上的配置文件的name

沒問題

4.利用webhooks實現自動刷新配置

向config服務端發送post請求

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

具體路徑根據項目來

在gitee的config管理中，點擊webhooks

url就填上面那個，因為需要公網才能測試，所以暫時不演示瞭。

設置完，改gitee的配置就會自動刷新瞭
