在前后端交互分离的体系下,我们后端一般会将返回给前端的信息数据进行格式的统一,然后返回前端json串;,一下我提供了一个模板,在实际开发中可进行参考

 

package com.project.util;

 

/**
* @Description: 自定义响应数据结构
* 200:表示成功
* 500:表示错误,错误信息在msg字段中
* 501:bean验证错误,不管多少个错误都以map形式返回
* 502:拦截器拦截到用户token出错
* 555:异常抛出信息
*/
public class JSONResult {

 

// 响应业务状态
private Integer status;

 

// 响应消息
private String msg;

 

// 响应中的数据
private Object data;

private String ok;    // 不使用

 

public static JSONResult build(Integer status, String msg, Object data) {
return new JSONResult(status, msg, data);
}

 

public static JSONResult ok(Object data) {
return new JSONResult(data);
}

 

public static JSONResult ok() {
return new JSONResult(null);
}

public static JSONResult errorMsg(String msg) {
return new JSONResult(500, msg, null);
}

public static JSONResult errorMap(Object data) {
return new JSONResult(501, "error", data);
}

public static JSONResult errorTokenMsg(String msg) {
return new JSONResult(502, msg, null);
}

public static JSONResult errorException(String msg) {
return new JSONResult(555, msg, null);
}

 

public JSONResult() {

 

}

 

 

 

public JSONResult(Integer status, String msg, Object data) {
this.status = status;
this.msg = msg;
this.data = data;
}

 

public JSONResult(Object data) {
this.status = 200;
this.msg = "OK";
this.data = data;
}

 

public Boolean isOK() {
return this.status == 200;
}

 

public Integer getStatus() {
return status;
}

 

public void setStatus(Integer status) {
this.status = status;
}

 

public String getMsg() {
return msg;
}

 

public void setMsg(String msg) {
this.msg = msg;
}

 

public Object getData() {
return data;
}

 

public void setData(Object data) {
this.data = data;
}

 

public String getOk() {
return ok;
}

 

public void setOk(String ok) {
this.ok = ok;
}

 

}
