前后端分离Springboot统一数据返回格式【简单明了】

1、结构：

1个启动类+1个控制层类+1个实体类+3个数据处理工具类(有一个枚举)

2、内容：

pom.xml

	1.8



	
		org.springframework.boot
		spring-boot-starter-web
	
	
	
		com.alibaba
		fastjson
		1.2.47
	

App.java

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

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

DataResult.java

import java.util.Date;
import org.springframework.web.bind.annotation.PostMapping;
import org.springframework.web.bind.annotation.RestController;
import com.alibaba.fastjson.JSONObject;
import com.liandao.xcl.entity.User;
import com.liandao.xcl.util.BaseResponse;

@RestController
public class DataResult {
	@PostMapping("/datass")
	public BaseResponse data(){
		JSONObject json=new JSONObject(true);//加true解决乱序问题
		json.put("User1", new User("张三", "zhangsan", new Date()));
		json.put("User2", new User("李四", "lisi", new Date()));
		json.put("User3", new User("王五", "wangwu", new Date()));
		return BaseResponse.resultmsgd(json);
	}
}

User.java

import java.util.Date;

import com.fasterxml.jackson.annotation.JsonFormat;

public class User {
private String username;
private String password;

}

BaseResponse.java

public class BaseResponse {

	private T resdata;
	//get set
	public ResStatus getResstatus() {
		return resstatus;
	}

	}
	//构造方法
	public BaseResponse() {

	}
	public BaseResponse(Integer code, String msg,T resdata) {
		super();
		this.resstatus = new ResStatus(code,msg);
		this.resdata = resdata;
	}
	//静态方法
	public static BaseResponse resultall(Integer code, String msg,T resdata){
		return new BaseResponse(code, msg, resdata);
	}
	public static BaseResponse resultmsg(){
		return new BaseResponse(ResResult.success.getCode(), ResResult.success.getMsg(), null);
	}
	public static BaseResponse resultmsgd(T resdata){
		return new BaseResponse(ResResult.success.getCode(), ResResult.success.getMsg(), resdata);
	}
}

ResResult.java（枚举）

public enum ResResult {
	success(0,"成功访问"),
	;
	private Integer code;
	private String msg;
	//get set
	public Integer getCode() {

	}
	public void setMsg(String msg) {
		this.msg = msg;
	}
	private ResResult(Integer code, String msg) {
		this.code = code;
		this.msg = msg;
	}
}

ResStatus.java

public class ResStatus {
	private Integer code;
	private String msg;
	//get set

	}
	public void setCode(Integer code) {
