統一返回結果

統一返回結果

這裏聲明一下，我用的這種是將異常和成功寫成枚舉的方式了，廢話不多說直接上代碼！！

枚舉類寫法

package com.xindong.common;

import lombok.Getter;

@Getter
public enum ResultCodeEnum {

    SUCCESS(true, 20000,"成功"),
    UNKNOWN_REASON(false, 20001, "未知錯誤"),
    BAD_SQL_GRAMMAR(false, 21001, "sql語法錯誤"),
    JSON_PARSE_ERROR(false, 21002, "json解析異常"),
    PARAM_ERROR(false, 21003, "參數不正確"),
    FILE_UPLOAD_ERROR(false, 21004, "文件上傳錯誤"),
    EXCEL_DATA_IMPORT_ERROR(false, 21005, "Excel數據導入錯誤");
    private Boolean success;

    private Integer code;

    private String message;

    private ResultCodeEnum(Boolean success, Integer code, String message) {
        this.success = success;
        this.code = code;
        this.message = message;
    }
}

全局統一返回結果類的寫法

package com.xindong.common.vo;

import com.xindong.common.ResultCodeEnum;
import io.swagger.annotations.ApiModel;
import io.swagger.annotations.ApiModelProperty;
import lombok.Data;

import java.util.HashMap;
import java.util.Map;

@Data
@ApiModel(value = "全局統一返回結果")
public class R {

    @ApiModelProperty(value = "是否成功")
    private Boolean success;

    @ApiModelProperty(value = "返回碼")
    private Integer code;

    @ApiModelProperty(value = "返回消息")
    private String message;

    @ApiModelProperty(value = "返回數據")
    private Map<String, Object> data = new HashMap<String, Object>();

    private R(){}

    public static R ok(){
        R r = new R();
        r.setSuccess(ResultCodeEnum.SUCCESS.getSuccess());
        r.setCode(ResultCodeEnum.SUCCESS.getCode());
        r.setMessage(ResultCodeEnum.SUCCESS.getMessage());
        return r;
    }

    public static R error(){
        R r = new R();
        r.setSuccess(ResultCodeEnum.UNKNOWN_REASON.getSuccess());
        r.setCode(ResultCodeEnum.UNKNOWN_REASON.getCode());
        r.setMessage(ResultCodeEnum.UNKNOWN_REASON.getMessage());
        return r;
    }

    public static R setResult(ResultCodeEnum resultCodeEnum){
        R r = new R();
        r.setSuccess(resultCodeEnum.getSuccess());
        r.setCode(resultCodeEnum.getCode());
        r.setMessage(resultCodeEnum.getMessage());
        return r;
    }

    public R success(Boolean success){
        this.setSuccess(success);
        return this;
    }

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

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

    public R data(String key, Object value){
        this.data.put(key, value);
        return this;
    }

    public R data(Map<String, Object> map){
        this.setData(map);
        return this;
    }
}

提示：

這裏將這兩塊代碼複製到上項目裏是可行的，若是不行私聊哦
