SpringBoot：自定义异常

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);
