响应体 ResponseBody

Design ResponseBody for Web application:

package org.example.springbootstart;

import org.example.springbootstart.util.ResponseCode;

public class Result<T> {
    private Integer code;
    private String msg;
    private T data;

    public Result() {
    }

    public Result(ResponseCode responseCode, T data) {
        this.code = responseCode.getCode();
        this.msg = responseCode.getMessage();
        this.data = data;
    }

    public Integer getCode() {
        return code;
    }

    public void setCode(Integer code) {
        this.code = code;
    }

    public String getMsg() {
        return msg;
    }

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

    public T getData() {
        return data;
    }

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

    public static <T> Result<T> success(T data) {
        return new Result(ResponseCode.SUCCESS, data);
    }

    public static <T> Result<T> success() {
        return new Result(ResponseCode.SUCCESS, null);
    }

    public static <T> Result<T> error(ResponseCode responseCode) {
        return new Result(responseCode, null);
    }

    @Override
    public String toString() {
        return "Result{" +
                "code=" + code +
                ", msg='" + msg + '\'' +
                ", data=" + data +
                '}';
    }
