封装前端响应结果

统一返回状态码

package com.wb.response;

/**
 * 统一返回状态码
 */
public enum ResultCode {
    /* 成功状态码 */
    SUCCESS(1, "成功"),
    /* 失败状态码 */
    FAILURE(0, "失败");
    

    private Integer code;
    private String message;

    ResultCode(Integer code, String message) {
        this.code = code;
        this.message = message;
    }

    public Integer code() {
        return this.code;
    }

    public String message() {
        return this.message;
    }

    public static Integer getCode(String name) {
        return getItem(name).code;
    }


    public static String getMessage(String name) {
        return getItem(name).message;
    }

    public static ResultCode getItem(String name) {
        for (ResultCode item : ResultCode.values()) {
            if (item.name().equals(name)) {
                return item;
            }
        }
        return null;
    }

    @Override
    public String toString() {
        return this.name();
    }
}

封装返回结果

package com.wb.response;

import lombok.Data;

import java.io.Serializable;

/**
 * 响应结果统一封装
 */

        this.code = resultCode.code();
        this.msg = resultCode.message();
    }

    /**
     * 请求成功不带返回值
     */
    public static Result success() {
