java中自定义一个异常类 在某些情况抛出自定的异常 ----------阻断程序

//=============定义异常类
package org.springblade.flow.engine.errorException;

/**
 * 自定义异常处理写入sap失败
 */
public class CallbackErrorException extends Exception{
    public CallbackErrorException(String detailMessage) {
        super(detailMessage);
    }
}

//============= 需要抛出异常的类

import org.flowable.engine.delegate.DelegateExecution;
import org.flowable.engine.delegate.ExecutionListener;
import org.springblade.desk.feign.IBusinessPartnerClient;
