我们在实现自定义异常的时候，我们需要继承 RuntimeException ，参考代码：
/*** <b>Function: </b> todo** @program: BizException* @Package: com.kingbal.king.common.core.exception* @author: dingcho* @date: 2024/09/14* @version: 1.0* @Copyright: 2024 www.kingbal.com Inc. All rights reserved.*/
public class BizException extends RuntimeException{private static final long serialVersionUID = 9104770577278712502L;/*** 状态码*/private int code;private ErrorCodeEnum errorEnum;public BizException(ErrorCodeEnum errorEnum, Throwable cause) {super(errorEnum.getMsg(), cause);this.code = errorEnum.getCode();this.errorEnum = errorEnum;}public BizException(ErrorCodeEnum errorEnum) {super(errorEnum.getMsg());this.code = errorEnum.getCode();this.errorEnum = errorEnum;}public BizException(ErrorCodeEnum errorEnum, String message) {super(message);this.code = errorEnum.getCode();this.errorEnum = errorEnum;}}/*** <b>Function: </b> todo** @program: ErrorCodeEnum* @Package: com.kingbal.king.common.core.constant.enums* @author: dingcho* @date: 2024/09/14* @version: 1.0* @Copyright: 2024 www.kingbal.com Inc. All rights reserved.*/
@Getter
@AllArgsConstructor
public enum ErrorCodeEnum {BIZ_PARAM_ERROR(400,"非法的参数!"),;/*** 类型*/private final Integer code;/*** 描述*/private final String msg;}
使用：
// 调用throw new BizException(ErrorCodeEnum.BIZ_PARAM_EROOR);
)
