SpringBoot学习3-热部署热加载/请求反馈

每次修改了代码都需要重新运行才可以生效，刚开始代码量少速度还能接受，后面代码量多了，重新运行的速度比较慢，所以需要使用到热加载。
关于热加载，有商业版的JRebel and XRebel插件可以使用，在插件中心安装完了重启IDE即可在右上角看见运行按钮，缺点就是要钱，也可以使用通用的devtools来实现，首先需要在pom里面加入依赖：

	org.springframework.boot
	spring-boot-devtools
	true

新版的IDE需要在设置里的高级设置开启自动make:

接着，我们可以运行项目，然后修改代码后，即可点击右上角小锤子来进行热加载

统一新建一个类，StatusReponse

package com.example.demo.controller;

import lombok.Data;

@Data
public class StatusReponse {

    //是否成功
    private boolean success;
    //状态码
    private int code;
    //状态消息
    private String msg;
    //附加数据
    private Object data;

    StatusReponse(){};

    
    public static StatusReponse success()
    {
        StatusReponse ajaxResponse = new StatusReponse();
        ajaxResponse.setCode(200);
        ajaxResponse.setSuccess(true);
        ajaxResponse.setMsg("查询成功");
        return ajaxResponse;
    }

    public static StatusReponse success(String msg,int code)
    {
        StatusReponse StatusReponse = new StatusReponse();
        StatusReponse.setCode(code);
        StatusReponse.setSuccess(true);
        StatusReponse.setMsg(msg);
        return StatusReponse;
    }

    public static StatusReponse success(Object data,String msg,int code)
    {
        StatusReponse StatusReponse = new StatusReponse();
        StatusReponse.setCode(code);
        StatusReponse.setData(data);
        StatusReponse.setSuccess(true);
        StatusReponse.setMsg(msg);
        return StatusReponse;
    }

    public static StatusReponse success(Object data,String msg)
    {
        StatusReponse StatusReponse = new StatusReponse();
        StatusReponse.setCode(200);
        StatusReponse.setData(data);
        StatusReponse.setSuccess(true);
        StatusReponse.setMsg(msg);
        return StatusReponse;
    }

    
    public static StatusReponse faild(int code)
    {
        StatusReponse StatusReponse = new StatusReponse();
        StatusReponse.setCode(code);
        StatusReponse.setSuccess(false);
        return StatusReponse;
    }

    public static StatusReponse faild(int code,String msg)
    {
        StatusReponse StatusReponse = new StatusReponse();
        StatusReponse.setCode(500);
        StatusReponse.setMsg(msg);
        StatusReponse.setSuccess(false);
        return StatusReponse;
    }

    public static StatusReponse faild()
    {
        StatusReponse StatusReponse = new StatusReponse();
        StatusReponse.setCode(500);
        StatusReponse.setSuccess(false);
        return StatusReponse;
    }
}

控制器使用StatusReponse.success(data,"查询成功");即可输出相关JSON。
