spring cloud config和bus组件实现自动刷新功能
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
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
