Manually refresh the client configuration content (Spring Cloud Config)

Manually refresh the client configuration content

Increased client project dependencies

<dependency>
  <groupId>org.springframework.boot</groupId>
  <artifactId>spring-boot-starter-actuator</artifactId>
</dependency>

Client project to modify the configuration file

增加management.endpoints.web.exposure.include=refresh,health,info

spring.application.name=spring-cloud-config-client
server.port=9006
spring.cloud.consul.host=127.0.0.1
spring.cloud.consul.port=8500
#设置不需要注册到 consul 中
spring.cloud.consul.discovery.register=false
#显示的暴露接入点
management.endpoints.web.exposure.include=refresh,health,info

Added support to refresh the client program notes

Add @RefreshScope notes on using the configuration center class:

@RestController
//刷新触发地址/actuator/refresh
@RefreshScope
public class ConfigTestController {

    //配置信息通过@Value注解读取,配置项用${配置项}读取
    @Value("${bluersw.config}")
    private String configBluersw;

    @RequestMapping("/ConfigTest")
    public String ConfigTest(){
        return this.configBluersw;
    }
}

Refresh test results

The Git warehouse configuration change content outside Test-5 (bluersw.config = Test-5), start the client program (spring-cloud-config-client), the client refresh the page 127.0.0.1:9006/ConfigTest, findings show content or Test-3, then execute:

curl -X POST http://127.0.0.1:9006/actuat/refresh

127.0.0.1:9006/ConfigTest refresh the page again, the page content appears as Test-5, instructions to configure the information in the client program reads the latest value.
