How to realize automatic refresh function of spring cloud config and bus components
This article focuses on "spring cloud config and bus components how to achieve automatic refresh function", interested friends may wish to have a look. The method introduced in this paper is simple, fast and practical. Next let the editor to take you to learn "spring cloud config and bus components how to achieve automatic refresh function" bar!
1. Start RabbitMQ
two。 Modify config server dependency: (the boot and cloud versions should not be too high, otherwise the request to refresh the configuration cannot be used)
Org.springframework.cloud spring-cloud-starter-consul-discovery org.springframework.boot spring-boot-starter-actuator org.springframework.cloud spring-cloud-config-server org.springframework.cloud spring-cloud-starter-bus-amqp org.springframework.boot spring-boot-starter-web
Configuration:
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: / # expose all endpoints Easy to send update configuration request management: endpoints: web: exposure: include: "*"
Startup: (startup class plus @ EnableConfigServer) mq will have a temporary queue
3. Modify the microservice (that is, the client) dependency:
Org.springframework.boot spring-boot-starter-web org.springframework.cloud spring-cloud-starter-consul-discovery org.springframework.boot spring-boot-starter-actuator org.springframework.cloud spring-cloud-starter-config org.springframework.cloud spring-cloud-starter-bootstrap org. Springframework.cloud spring-cloud-starter-bus-amqp
Configuration: unchanged (the configuration of rabbitmq should be written to gitee) bootstrap.properties
Spring.cloud.consul.host=localhostspring.cloud.consul.port=8500spring.application.name=CONFIGCLIENTspring.cloud.config.discovery.service-id=CONFIGSERVERspring.cloud.config.discovery.enabled=truespring.cloud.config.name=configspring.cloud.config.label=masterspring.cloud.config.profile=dev
Run:
Wrote a test method.
The name property is the name of the profile on gitee
No problem
4. Using webhooks to realize automatic refresh configuration
Send a post request to the config server
Http://localhost:8080/actuator/bus-refresh
The specific path is based on the project
In the config Management of gitee, click webhooks
Url will fill in the above one, because you need a public network to test, so I won't demonstrate it for the time being.
After setting up, changing the configuration of gitee will refresh automatically.
At this point, I believe you have a deeper understanding of "spring cloud config and bus components how to achieve automatic refresh function", might as well to the actual operation of it!
