- Result类：用于后台返回给前台的结果
public class Result {
// 结果状态码
private Integer code;
// 结果消息
private String msg;
// 结果数据
private Object data;
public Result() {
super();
}
public Result(Integer code, String msg, Object data) {
this.code = code;
this.msg = msg;
this.data = data;
}
/**
* 根据状态码枚举设置状态码和状态信息的值
* @param code 状态码枚举
*/
public void setResultCode(ResultCode code) {
this.code = code.getCode();
this.msg = code.getMessage();
}
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 Object getData() {
return data;
}
public void setData(Object data) {
this.data = data;
}
@Override
public String toString() {
return "Result{" +
"code=" + this.code +
", msg='" + this.msg + '\'' +
", data=" + this.data +
'}';
}
}
- ResultCode类：结果状态枚举
public enum ResultCode {
SUCCESS(10001, "成功"),
FAILURE(10002, "失败"),
UNKNOWN_ERROR(10003, "未知错误"),
SYSTEM_INNER_ERROR(10004, "系统繁忙，请稍后重试"),
PARAM_VALIDATE_SUCCESS(10005, "参数校验成功"),
/* 参数错误：20001-29999 */
PARAM_IS_INVALID(20001, "参数无效"),
PARAM_IS_BLANK(20002, "参数为空"),
PARAM_TYPE_BIND_ERROR(20003, "参数类型错误"),
PARAM_NOT_COMPLETE(20004, "参数缺失");
// 结果状态码
private Integer code;
// 结果消息
private String message;
ResultCode(Integer code, String message) {
this.code = code;
this.message = message;
}
public Integer getCode() {
return code;
}
public String getMessage() {
return message;
}
}
- ResultUtil类：返回结果工具类
public class ResultUtil {
/**
* 成功无返回数据
* @return
*/
public static Result success() {
Result result = new Result();
result.setResultCode(ResultCode.SUCCESS);
return result;
}
/**
* 成功带返回数据
* @param data 响应数据
* @return
*/
public static Result success(Object data) {
Result result = new Result();
result.setResultCode(ResultCode.SUCCESS);
result.setData(data);
return result;
}
/**
* 自定义状态码并带返回数据
* @param code 结果状态码
* @param data 响应数据
* @return
*/
public static Result success(ResultCode code, Object data) {
Result result = new Result();
result.setResultCode(code);
result.setData(data);
return result;
}
/**
* 失败不带返回数据
* @return
*/
public static Result failure() {
Result result = new Result();
result.setResultCode(ResultCode.FAILURE);
return result;
}
/**
* 失败带返回数据
* @param data 响应数据
* @return
*/
public static Result failure(Object data) {
Result result = new Result();
result.setResultCode(ResultCode.FAILURE);
result.setData(data);
return result;
}
}
