controller

/**

 * @Date: 2020/7/27 5:01
 */

// 将配合信息以rest接口的形式暴露
@RestController
@RefreshScope
public class ConfigClientController
{
    @Value("${config.info}")
    private String configInfo;

    @RequestMapping("/configInfo")
    public String getConfigInfo()
    {
        return configInfo;
    }
}

主函数入口

/**
 * @Author: EzerbelCN
 * @Date: 2020/7/27 4:44
 */

@SpringBootApplication
@EnableEurekaClient
public class ConfigClientMain3355 {
    public static void main(String[] args){
        SpringApplication.run(ConfigClientMain3355.class,args);
    }
}

启动测试

测试刷新

在git上提交配置文件的修改之后，需要向目标客户端发送post请求，refresh刷新！

注意前面的配置中，默认的actuator被我改成了monitor

curl -X POST "http://localhost:3355/monitor/refresh"
