1、错误描述

Exception in thread "main" org.hibernate.ObjectNotFoundException: No row with the given identifier exists: [com.you.hibernate.model.TStudentInfo#1]at org.hibernate.internal.SessionFactoryImpl$1$1.handleEntityNotFound(SessionFactoryImpl.java:247)at org.hibernate.proxy.AbstractLazyInitializer.checkTargetState(AbstractLazyInitializer.java:171)at org.hibernate.proxy.AbstractLazyInitializer.initialize(AbstractLazyInitializer.java:160)at org.hibernate.proxy.AbstractLazyInitializer.getImplementation(AbstractLazyInitializer.java:195)at org.hibernate.engine.internal.StatefulPersistenceContext.unproxyAndReassociate(StatefulPersistenceContext.java:667)at org.hibernate.event.internal.DefaultDeleteEventListener.onDelete(DefaultDeleteEventListener.java:90)at org.hibernate.event.internal.DefaultDeleteEventListener.onDelete(DefaultDeleteEventListener.java:74)at org.hibernate.internal.SessionImpl.fireDelete(SessionImpl.java:946)at org.hibernate.internal.SessionImpl.delete(SessionImpl.java:925)at com.you.hibernate.dao.StudentDao.deleteStuInfo(StudentDao.java:116)at com.you.hibernate.dao.StudentDao.main(StudentDao.java:167)

2、错误原因

public static void deleteStuInfo(int id){Session session = HibernateSessionFactory.getSession();session.beginTransaction();TStudentInfo student = (TStudentInfo)session.load(TStudentInfo.class, id);session.delete(student);session.getTransaction().commit();System.out.println("删除成功！");}/** * 方法描述： * 创建作者：游海东 * 创建日期：2017-2-20 * 创建时间：下午5:20:14 * 方法名称：main * 方法类型：StudentDao * 返回类型：void * @param args */public static void main(String[] args) {int id = 1;deleteStuInfo(id);}

由于id=1的记录已经删除，再次调用删除方法，会报错

3、解决办法

（1）首先，在调用删除方法前需要按照ID进行查询一次

（2）然后，如果该ID的记录存在，才能调用删除方法

（3）最后，调用删除操作进行删除记录
