在Git端修改配置后如何让客户端生效?
访问接口修改
弊端: 通过restart耗时比较长,因此就有了RefreshScope
RefreshScope
package com.lkl.springcloud.config.client;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
import org.springframework.cloud.context.config.annotation.RefreshScope;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
/**
* Created by liaokailin on 16/4/28.
*/
@EnableAutoConfiguration
@ComponentScan
@RestController
@RefreshScope
public class Application {
@Value("${name:World!}") String name ;
@RequestMapping("/")
public String home(){
return "Hello " + name;
}
public static void main(String[] args) {
SpringApplication.run(Application.class,args);
}
}
