本文详细介绍了如何在Spring Boot应用中实现响应结果的统一格式化，包括封装返回对象、公共枚举、Util工具类、自定义异常处理等关键步骤。

第一步封装返回统一格式:

import lombok.Data;

@Data
public class Result<T> {

    private Integer code;


    private String msg;


    private T data;
}

第二步封装公共枚举:

/**
 * @author liuXiangPeng
 * @version 1.0.0
 * @description 公共枚举接口
 */
public interface CommonEnum {
    Number getCode();
    String getMessage();
}

第三步封装ResultUtils：

import com.nh.schoolexam.schoolexam.enmus.ResultEnum;
import com.nh.schoolexam.schoolexam.vo.Result;

public class ResultUtils {

    public static Result success(Object obj) {
        return getResult(ResultEnum.SUCCESS, obj);
    }

    public static Result success() {
        return getResult(ResultEnum.SUCCESS, null);
    }

    public static Result fail() {
        return getResult(ResultEnum.FAIL, null);
    }

    public static Result getResult(ResultEnum re) {
        return getResult(re, null);
    }

    public static Result getResult(ResultEnum re, Object obj) {
        return getResult(re.getCode(), re.getMessage(), obj);
    }

    public static Result getResult(Integer code, String msg) {
        return getResult(code, msg, null);
    }


    public static Result getResult(Integer code, String msg, Object obj) {
        Result result = new Result();
        result.setCode(code);
        result.setMsg(msg);
        result.setData(obj);
        return result;
    }

}

第四步封装返回参数:

public enum ResultEnum implements CommonEnum {

    SUCCESS(200, "成功"),
    UNVALID(3000, "用户未登录"),
    UNAPPLY_POST(3010, "用户不存在或者密码错误"),
    ERROR(5000, null);

    private Integer code;

    private String message;

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

    @Override
    public Integer getCode() {
        return code;
    }

    @Override
    public String getMessage() {
        return message;
    }
}

第五步封装自定义异常:

@ControllerAdvice
@Slf4j
public class ExceptionHandle {

    @ExceptionHandler(value = CustomException.class)
    @ResponseBody
    public Result handleVerificationCodeException(CustomException e){
        log.error("【自定义异常】"+e.getLogInfo()+"\n{}",e);
        return ResultUtils.getResult(e.getCode(),e.getMessage());
    }

    @ExceptionHandler(value = Exception.class)
    @ResponseBody
    public Result handleException(Exception e){
        log.error("【系统异常】\n{}",e);
        return ResultUtils.getResult(ResultEnum.ERROR.getCode(),"系统异常");
    }


}

@Data
public class CustomException extends RuntimeException {

    private static final long serialVersionUID = -4435837929656377189L;

    private Integer code;

    private String logInfo;

    public CustomException(ResultEnum re, String logInfo) {
        super(re.getMessage());
        this.code = re.getCode();
        this.logInfo = logInfo;
    }
}
