启动类

/**

 * 原因也很简单，我们的java源码目录下没有目录，我们手动加一个也就正常了，
 * 为了写点体会和这里没必要用到包和类，所以使用这种方式
 */

配置读取

/**
 * 当有请求/fresh节点的时候，会重新请求一次ConfigServer去拉取最新的配置文件
 * 请求/fresh需要有几点要求：1.加actuator的依赖 2.SpringCloud1.5以上需要设置 management.security.enabled=false
 * 这个Controller的作用是查看from这个key的值
 */
@RestController
@RefreshScope //开启更新功能
@RequestMapping("api")
public class TestController {

    @Value("${from}")
    private String fromValue;

    /**
     * 返回配置文件中的值
     */
    @GetMapping("/from")
    @ResponseBody
    public String returnFormValue(){
        return fromValue;
    }
}
