org.springframework.orm.hibernate4.HibernateOptimisticLockingFailureException

项目是Java Web

使用框架:struts,hibernatespring

构建工具:maven

使用一个商品管理系统,用于管理超市商品

 

项目结构如下:
org.springframework.orm.hibernate4.HibernateOptimisticLockingFailureException
 执行如下操作时报错
org.springframework.orm.hibernate4.HibernateOptimisticLockingFailureException
 点击“delete”,删除超市时,报错。

注意:是有时候报错,不是每次删除都报错。

报错信息如下:

原因分析

执行删除超市的action 是DeleteSupermarketAction,内容如下:

Java代码  org.springframework.orm.hibernate4.HibernateOptimisticLockingFailureException
  1. package com.shop.jn.action.supermarket;  
  2.   
  3. import com.opensymphony.xwork2.ActionSupport;  
  4. import com.shop.jn.dao.SupermarketDao;  
  5. import com.shop.jn.entity.Supermarket;  
  6. /*** 
  7.  * 删除超市. 
  8.  *  
  9.  * @author huangwei 
  10.  * 
  11.  */  
  12. public class DeleteSupermarketAction extends ActionSupport {  
  13.   
  14.     private static final long serialVersionUID = 7753616847784594121L;  
  15.     private Supermarket supermarket;  
  16.     private SupermarketDao supermarketDao;  
  17.   
  18.     @Override  
  19.     public String execute() throws Exception {  
  20.         this.supermarketDao.delete(this.supermarket);  
  21.         return super.execute();  
  22.     }  
  23.   
  24.     public Supermarket getSupermarket() {  
  25.         return supermarket;  
  26.     }  
  27.   
  28.     public void setSupermarket(Supermarket supermarket) {  
  29.         this.supermarket = supermarket;  
  30.     }  
  31.   
  32.     public SupermarketDao getSupermarketDao() {  
  33.         return supermarketDao;  
  34.     }  
  35.   
  36.     public void setSupermarketDao(SupermarketDao supermarketDao) {  
  37.         this.supermarketDao = supermarketDao;  
  38.     }  
  39.       
  40. }  

 说明:supermarket 是通过依赖注入的,注入的字段是id(http://localhost:8080/shop_goods/supermarket/deleteSupermarket.action?supermarket.id=9)。

此时supermarket 的状态是detached 脱管的(脱离管理的),this.supermarketDao.delete 的方法体如下:

Java代码  org.springframework.orm.hibernate4.HibernateOptimisticLockingFailureException
  1. this.sessionFactory.getCurrentSession().delete(obj);  

但是hibernate api中对delete 的方法说明如下:

void

delete(Object object) 
          Remove a persistent instance from the datastore.

 要求参数必须是persistent 持久化的的状态。

 

如何解决呢?

使用原生的sql语句

我在dao中新增了一个方法:

Java代码  org.springframework.orm.hibernate4.HibernateOptimisticLockingFailureException
  1. public void deleteHQL(int id) {  
  2.         this.sessionFactory.getCurrentSession()  
  3.                 .createQuery("delete from Supermarket where id=?")  
  4.                 .setInteger(0, id).executeUpdate();  
  5.     }  

 在DeleteSupermarketAction 中调用如下:

Java代码  org.springframework.orm.hibernate4.HibernateOptimisticLockingFailureException
  1. @Override  
  2.     public String execute() throws Exception {  
  3.         this.supermarketDao.deleteHQL(this.supermarket.getId());  
  4.         return super.execute();  
  5.     }
