通用返回类型定义

本文主要是介绍通用返回类型定义，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

定义业务异常类：

import lombok.AllArgsConstructor;
import lombok.Data;@Data
@AllArgsConstructor
public class BusinessException extends RuntimeException{private String errorCode;private String errorMsg;
}

错误枚举类：

public enum UnifiedResponseEnums {BAD_PARAM("1002","参数有错"),NOT_FOUND("1003","资源不存在"),NO_PERMISSION("1004","权限不足"),BAD_INPUT_PARAM("1005","入参有问题"),BAD_EMAIL_PARAM("1006","email入参有问题"),BAD_ID_PARAM("1007","id入参有问题"),BAD_IP("1008","非法IP"),INVALLD_TOKEN("1009","无效令牌"),TOO_MANY_PARAMS("1010","参数过载");private String errorCode;private String errorMsg;UnifiedResponseEnums(String errorCode, String errorMsg) {this.errorCode = errorCode;this.errorMsg = errorMsg;}public String getErrorCode() {return errorCode;}public void setErrorCode(String errorCode) {this.errorCode = errorCode;}public String getErrorMsg() {return errorMsg;}public void setErrorMsg(String errorMsg) {this.errorMsg = errorMsg;}
}

Controller 中使用：

UnifiedResponseEnums enum1 = UnifiedResponseEnums.valueOf(UnifiedResponseEnums.class,"BAD_PARAM");
throw new BusinessException(enum1.getErrorCode(), enum1.getErrorMsg());

设置通用返回结果：

public class JsonResultObject<T> {private String Code;private String errorCode;private String message;private String errorMessage;private T data;public JsonResultObject(String code, String message, T data) {Code = code;this.message = message;this.data = data;}public JsonResultObject(String code, String errorCode, String message, String errorMessage, T data) {Code = code;this.errorCode = errorCode;this.message = message;this.errorMessage = errorMessage;this.data = data;}public JsonResultObject(String errorCode, String errorMessage) {this.errorCode = errorCode;this.errorMessage = errorMessage;}public String getCode() {return Code;}public void setCode(String code) {Code = code;}public String getErrorCode() {return errorCode;}public void setErrorCode(String errorCode) {this.errorCode = errorCode;}public String getMessage() {return message;}public void setMessage(String message) {this.message = message;}public String getErrorMessage() {return errorMessage;}public void setErrorMessage(String errorMessage) {this.errorMessage = errorMessage;}public T getData() {return data;}public void setData(T data) {this.data = data;}
}

错误返回定义：

public class ErrorResult <T>{private String errorMessage;private String errorCode;private T data;public ErrorResult(String errorCode,String errorMessage, T data) {this.errorMessage = errorMessage;this.errorCode = errorCode;this.data = data;}public String getErrorMessage() {return errorMessage;}public void setErrorMessage(String errorMessage) {this.errorMessage = errorMessage;}public String getErrorCode() {return errorCode;}public void setErrorCode(String errorCode) {this.errorCode = errorCode;}public T getData() {return data;}public void setData(T data) {this.data = data;}
}
