在Git端修改配置后如何讓客戶(hù)端生效？

訪(fǎng)問(wèn)接口修改

• refresh
  post方式執(zhí)行http://localhost/refresh 會(huì)刷新env中的配置
• restart
  如果配置信息已經(jīng)注入到bean中，由于bean是單例的，不會(huì)去加載修改后的配置
  需要通過(guò)post方式去執(zhí)行http://localhost/restart,
  需要通過(guò)application.properties中配置endpoints.restart.enabled=true啟動(dòng)指定的端口

弊端： 通過(guò)restart耗時(shí)比較長(zhǎng)，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);
    }
}
