请教Spring对于Hibernate的Session管理

问题:
假设我有一个daoA 对象, daoB对象,两个DAO类都是继承自HibernateDaoSupport类,两个对象在ServiceC类里被放在同一个事物里执行DAO中有的方法。比如说daoA.save(),daoB.delete()。
在以上的情况下是不是Spring会提供两个sesssion来分别执行save和delete。
如果我从dao取出的对象被传播到JSP上,并且这个对象配置了有lazy load,是不是会引起异常,为什么。

另外,假设我配置了openSessionInViewFilter,从数据库中取出的对象可以在JSP上做LAZY LOAD,那这种方式和我在 Service中直接做initialize的优缺点分别是什么?

=================================================

我自己回答一下。
刚刚看了Spring的源代码,它的strategy是这样的,当你调用HibernateTempalte.save()的时候,spring会检查你的config,看是否允许强制enforceNewSession,或者enforceNativeSession,通过这两个不同的策略。spring决定是否是强制创建和当前thread绑定的一个hibernate session,或者只在当前环境下查找一个已经有的session。
如果选择了enForceNewSession,那就意味着HibernateTemplate的每一个操作都会是立刻打开session,但是注意,我没看到关闭session。也就是说,上面的问题会有2个session出现。

2个回答

OpenSessionInView的话, 是针对一个Request开一个HibernateSession.

如果你不用OpenSessinInView的话 , 你的Session可能回在 Transaction.commit的地方就终结了. 如过你在Session终结后还想用
lazyloading的方式访问 Hibernate PoJo的相关对象,就会有问题.

看你配置的拦截方法策略了

请教Spring + Hibernate进行开发时,session关闭问题
程序代码 <br />public class DaoReal extends HibernateDaoSupport implements Dao { <br />  public List&lt;user&gt; getAll() { <br />    Session s = super.getSession(); <br />    try { <br />      return s.createQuery("from User").list(); <br />    } finally { <br />      s.close(); <br />    } <br />  } <br />} <br /> <br /> <br />问题:(利用session.createQuery(...)方法的隐患) <br />上面的例子中隐藏了一个问题,数据库连接并没有被关闭,在我们的印象中这件事似乎应该是Spring的。程序执行后,好像也没有什么问题,但是连续执行该语句n次(n&lt;=最大连接数,如果没有指定最大连接数,那么默认为10次)后,系统处于等待状态,不会继续执行了,控制台上并没有输出任何信息。打开log文件,发现系统抛出java.lang.IllegalStateException: Pool not open的异常,无法打开连接。这说明系统连接池中所有的连接都在使用中。 <br /> <br />执行n遍后依然停止响应。问题出在哪里呢?其实Spring的Session总是与某个线程绑定的,而这个线程往往就是承载Servlet或Jsp的那个线程,也就是说,它的生命周期scope是request的。在上面的例子中,我们利用getSession强制获得了Hibernate的 Session,这个Session可能是当前事务中之前使用过的,或者可能是一个新的,并不在当前事务中,Spring只对当前事务中的Session 进行关闭。 <br /> <br /> <br />请教大家有什么解决办法没? 还是我提的问题是错误的?谢谢大家?<br /><strong>问题补充</strong><br />回楼上: <br />用到了hibernate+spring的话,一般我们直接用getHibernateTemplate().find("from User")这类型的查询。 <br /> <br />单是现在我项目里面程序用到这个类型的: <br />Session s = super.getSession(); <br />try { <br />      return s.createQuery("from User").list(); <br />  } finally { <br />      s.close(); <br />  } <br /> <br />我们测试中好像发现了这个session不能完全关闭好像。是不是这么回事??<br /><strong>问题补充</strong><br />在使用Spring进行系统开发的时候,数据库连接一般都是配置在Spring的配置文件中,并且由Spring来管理的。在利用Spring + Hibernate进行开发时也是如此。 <br /> <br />getHibernateTemplate().find("from User"); <br />这类型的我们并没有关闭Session,但程序并没有任何问题,那是因为Spring已经帮我们关闭了。 <br /> <br /><br /><strong>问题补充:</strong><br />getSession()是从当前的ThreadLocal中拿到的SESSION <br />就是说可以不用关闭SESSION,但这个线程结束的时候,SESSION就没了。。 <br /> <br /> <br />但是我们的请求也许也许没有响应,一直在请求过程中,也是就是这个线程还没结束,那这个session也就没有关闭吧!

hibernate DAO中关于session的管理
最近在整理hibernate的性能优化时,碰到了session的问题。 有几个问题不解,想在此请教一下各位高手们。 1、hibernate官网中介绍了一种threadlocal模式对session进行管理,本人也在filter中设置了这种功能,的确自己创建的session确实达到了与线程绑定的功能,但是对于DAO这一层(与SPRING整合)在使用getHibernateTemplate的回调函数中的session却无法达到该目的,也即getHibernateTemplate每次都创建了一个新的session,具体代码如下: fruitDAO.getHibernateTemplate().execute(new HibernateCallback(){ public Object doInHibernate(Session session){ System.out.println(session.hashCode()); return null; } }); 每次打出来的hashCode都不一样。 2、hibernate对于频繁创建关闭session的代价到底有多少,在系统中配置了连接池,session在关闭时是否对hibernate的数据库连接有影响。 谢谢各位了。
请教一个hibernate和spring整合时的问题
在整合的过程中,发现一个问题,session并没有关闭。以下是说明: [code="java"]protected Session getSession() { return this.sessionFactory.getCurrentSession(); }[/code] 这是获取session的方法 [code="java"](T)this.getSession().get(this.clazz, id)[/code] 这是获取对象的方法 事务在配置文件中进行配置: [code="java"] <bean id="transactionManager" class="org.springframework.orm.hibernate4.HibernateTransactionManager"> <property name="sessionFactory" ref="sessionFactory" /> </bean>[/code] 正常的情况来说,获取对象后,session就应该关闭了,可是在后面的测试中发现sesion并没有关闭,仍然可以查询出关联对象。网上说这种session不用手动关闭,请问它何时关闭

No Hibernate Session bound to thread

<p><span style="font-size: small;">场景是这样: <br>    有个提交申请单的操作,需三个动作:新增申请记录表记录、新增申请详单表记录,整个过程需完整,才能提交事务,其中一个过程失败,则需回到操作前状态,采用的是Spring声明式事务配置,但新增申请详单表记录时,由于插入数据量较大,发现用默认的HibernateTemplate里的save方法一条一条记录添加速度较慢,就使用了Hibernate批量插入,发现如果过程无错误,也会提示一个错误:java.lang.IllegalStateException: No value for key [org.hibernate.impl.SessionFactoryImpl@12421db] bound to thread [http-8080-Processor20] <br>,查了下估计是由于批量插入那边用了Hibernate自带的事务管理,释放了Hibernate下的session,和Spring配置的事务管理有冲突,有没有可以支持Spring自带事务管理,并且支持批量插入大量数据的方法,请教大家如何解决呢? </span></p> <p><span><font style=""> <p><br><span style="font-size: small;">附上大致代码:</span></p> </font></span></p> <p> </p> <p> </p> <p><span style="font-size: small;"> </span></p> <p><span style="font-size: small;">申请Service实现类大致Java代码:</span></p> <p> </p> <p> </p> <pre name="code" class="java">public void applyCard(CardInfo cardInfo, List&lt;CardDetail&gt; cardDetails){ //新增申请记录表记录 applyDAO.saveCardInfo(cardInfo); //新增申请详单表记录 applyDAO.batchSaveCardDetail(cardDetails); }</pre> <p> </p> <p><span style="font-size: small;">申请applyDAO实现类的batchSaveCardDetail方法(Hibernate批量插入):</span></p> <p><span style="font-size: small;"> </span></p> <p><span style="font-size: small;"><font style="" size="3"> <pre name="code" class="java">public void batchSaveCardDetail(List&lt;TCardInfo&gt; cardDetails) { Session session = this.getSession(); Transaction tx=null; try{ tx=session.beginTransaction(); for(int i=0;i&lt;cardDetails.size();i++){ session.save(cardDetails.get(i)); if(i%50 == 0){ session.flush(); session.clear(); } } tx.commit();//提交事务 }catch(Exception ex){ ex.printStackTrace(); tx.rollback();//出错则回滚 }finally{ session.close();//关闭session } }</pre> </font></span> </p> <pre name="code" class="java"></pre> <p><span style="font-size: small;"> <p>Spring相关配置如下:</p> <p> </p> <pre name="code" class="xml">&lt;!-- 应用的Spring里的Hibernate事务管理 --&gt; &lt;bean id="transactionManager" class="org.springframework.orm.hibernate3.HibernateTransactionManager"&gt; &lt;property name="sessionFactory" ref="sessionFactory" /&gt; &lt;/bean&gt; &lt;!-- 配置事务拦截器--&gt; &lt;bean id="transactionInterceptor" class="org.springframework.transaction.interceptor.TransactionInterceptor"&gt; &lt;property name="transactionManager" ref="transactionManager" /&gt; &lt;property name="transactionAttributes"&gt; &lt;props&gt; &lt;prop key="applyCard"&gt;PROPAGATION_REQUIRED&lt;/prop&gt; &lt;/props&gt; &lt;/property&gt; &lt;/bean&gt; &lt;!-- 根据事务拦截器为目标bean自动创建事务代理 --&gt; &lt;bean class="org.springframework.aop.framework.autoproxy.BeanNameAutoProxyCreator"&gt; &lt;property name="beanNames"&gt; &lt;list&gt; &lt;value&gt;applyService&lt;/value&gt; &lt;/list&gt; &lt;/property&gt; &lt;property name="interceptorNames"&gt; &lt;list&gt; &lt;value&gt;transactionInterceptor&lt;/value&gt; &lt;/list&gt; &lt;/property&gt; &lt;/bean&gt; &lt;!-- 申请Service --&gt; &lt;bean id="applyService" class="service.impl.ApplyServiceImpl"&gt; &lt;property name="applyDAO" ref="applyDAO"/&gt; &lt;/bean&gt;</pre> <p>  </p> <font style="" size="3"> <p> </p> </font></span></p> <p> </p>

OpenSessionInView里的Session不能自动关闭?
在Struts2+spring+hibernate集成的项目里,用到了spring的OpenSessionInViewFilter过滤器,来延长Session的生命周期,但在使用过程中,lasy加载正常是可以用的,就是session不会自动关闭。我查看源码里有下面一段 [code="java"] public static void closeSession(Session session) { if (session != null) { logger.debug("Closing Hibernate Session"); try { session.close(); } catch (HibernateException ex) { logger.debug("Could not close Hibernate Session", ex); } catch (Throwable ex) { logger.debug("Unexpected exception on closing Hibernate Session", ex); } } } [/code] 上面的logger根本就没有输入,也就是说没有进入这个地方 [code="java"] logger.debug("Closing single Hibernate Session in OpenSessionInViewFilter"); closeSession(sessionHolder.getSession(), sessionFactory); [/code] 只运行了上面那个logger 不清楚是为什么,向高手请教~~~ [b]问题补充:[/b] 他是在完成response后,在过滤器最后关闭的,如果不关闭的话,他占用的数据库连接就没有关闭,一会连接就不够了。。

如何从Session中获取不受管的Connection
请教如何从Session中获取不受管的Connection? 项目是用Spring管理事务的,现在一个业务有这样的需求:在一个方法的外层事务中,需要嵌套一个事务,通过这个嵌套事务获取一些独占资源(为了避免获取独占资源时事务耗时太长,所以单独做了一个嵌套事务用于获取独占资源并更新资源的状态)。 目前我直接从另外一个Session中获取了一个Connection对象并当做参数传到了Spring的doInHibernate方法中使用,但程序偶尔会报“Connection已经被关闭”的错。 请问应该怎样才能获取一个不被Spring管控的Connection呢?我可以自己对该Connection进行事务和资源释放的管理。

关于Spring事务管理及自定义异常抛出的问题
在项目开发中,[b]自定义了一个异常类[/b],继承Exception。 整体使用Spring的容器管理方式,事务管理在Service层来控制,现想如下设计:action捕获Service的异常,进行相关处理;在[b]Service层,就需要抛出自定义的异常类;[/b]dao不捕获异常。当Service加上事务处理就捕获不了异常信息,具体代码如下:[code="java"]public User saveUser(User user) throws GeneralException { User u = new User(); try { user.setUserType("10"); user.setStatus("10"); user.setPostCounts(0); user.setPassword("aaaa"); user.setCreateTime(new Date()); user.setLoginCounts(0); user.setLoginName("test" + (int) Math.random() * 20); user.setCreateTime(new Date()); user.setCurrentLoginIp("10.10.0.1"); user.setCurrentLoginTime(new Date()); user.setLastLoginIp("10.10.0.1"); user.setLastLoginTime(new Date()); u = userDao.saveUser(user); User us = userDao.getUser(4); us.setStatus("900");//【这儿会报个异常】 userDao.updateUser(us); } catch (Exception e) { e.printStackTrace(); System.out.println("============:exception execute."); throw new GeneralException(); } return u; }[/code],此时可以捕获到异常信息,报如下错误:[code="java"]No Hibernate Session bound to thread, and configuration does not allow creation of non-transactional one here[/code];当在方法上加@Transactional事务处理,异常就捕获不到了。 [i][b]另,程序采用Spring注解方式。[/b][/i] 请教各位大虾,谢谢!      
请教高手...
最近在研究 spring 源代码 先研究的第一个问题 session 是 怎么关闭的... session.clear(); ?什么意思 public static void releaseSession(Session session, SessionFactory sessionFactory) { if (session == null) { return; } // Only close non-transactional Sessions. if (!isSessionTransactional(session, sessionFactory)) { closeSessionOrRegisterDeferredClose(session, sessionFactory); } } 这个方法 中 isSessionTransactional 是干什么? static void closeSessionOrRegisterDeferredClose(Session session, SessionFactory sessionFactory) { Map<SessionFactory, Set<Session>> holderMap = deferredCloseHolder.get(); if (holderMap != null && sessionFactory != null && holderMap.containsKey(sessionFactory)) { logger.debug("Registering Hibernate Session for deferred close"); // Switch Session to FlushMode.MANUAL for remaining lifetime. session.setFlushMode(FlushMode.MANUAL); Set<Session> sessions = holderMap.get(sessionFactory); sessions.add(session); } else { closeSession(session); } } closeSessionOrRegisterDeferredClose 方法 和 holderMap.containsKey ? 希望大侠不 吝赐教 ...
用spring注入sessionfactory,总是null,请教大家帮我看看是什么问题
用ssh做的一个小东西,写了泛型dao,然后继承了hibernatedaosupport,然而 在方法里面用getHibnerateTemplate()时总是null。 我用main方法测试都是成功注入的,还有在其它地方自己new一个然后传入sessionFactory,输出sessionFactory和getHibneratemTemplate都是有值的,但是进入方法总是null,我试了一天都解决不了。 前提:我的所有包都引入好了,包括互相协调的包,由于太多,我就贴了一些相关的方法代码,请大家帮我看看。 另外,还有没有更好的写法?或者比hibernateDaoSupport更好用的模板,有的话,请指点一下,谢谢 这个是BaseDao public interface BaseDao<T extends Serializable , ID extends Serializable> { void save(T entity); void update(T entity); List<T> findAll(Class<T> entityClass); ``` ``` 这是BaseDaoImpl public class BaseDaoImpl<T extends Serializable , ID extends Serializable> extends HibernateDaoSupport implements BaseDao<T, ID> { @Override public void save(T entity) { getHibernateTemplate().save(entity); } @Override public void update(T entity) { getHibernateTemplate().update(entity); @Override public List<T> findAll(Class<T> entityClass) { String hql = "from " + entityClass; System.out.println("template---"+getHibernateTemplate()); System.out.println("hql---"+hql); System.out.println("sessionFactory---"+super.getSessionFactory()); return (List<T>)getHibernateTemplate().find(hql); } ``` ``` 这是BaseService public interface BaseService<T extends Serializable , ID extends Serializable> { void save(T entity); void update(T entity); List<T> findAll(Class<T> entityClass); ``` ``` 这是BaseServiceImpl public class BaseServiceImpl<T extends Serializable , ID extends Serializable> implements BaseService<T, ID> { private BaseDao<T , ID> baseDao; public void setBaseDao(BaseDao<T , ID> baseDao){ this.baseDao = baseDao; } @Override public void save(T entity) { baseDao.save(entity); } @Override public void update(T entity) { baseDao.update(entity); } @Override public List<T> findAll(Class<T> entityClass) { return baseDao.findAll(entityClass); } ``` ``` 这是web.xml <filter> <filter-name>Struts2</filter-name> <filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter</filter-class> </filter> <filter-mapping> <filter-name>Struts2</filter-name> <url-pattern>/*</url-pattern> </filter-mapping> <listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener> <context-param> <param-name>contextConfigLocation</param-name> <param-value>classpath:applicationContext.xml</param-value> </context-param> ``` ``` 这是applicationContext.xml <?xml version="1.0" encoding="UTF-8"?> <beans xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://www.springframework.org/schema/beans" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-4.2.xsd"> <bean id="sessionFactory" class="org.springframework.orm.hibernate5.LocalSessionFactoryBean"> <property name="configLocation" value="classpath:hibernate.cfg.xml"> </property> </bean> <bean id="baseDaoImpl" class="com.lamp.dao.impl.BaseDaoImpl"> <property name="sessionFactory" ref="sessionFactory"/> </bean> ```<bean name="showAllContactAction" class="com.lamp.action.ShowAllContactAction" scope="prototype"> <property name="contactServiceImpl"> <bean class="com.lamp.service.impl.ContactServiceImpl"></bean> </property> </bean> ``` 这是action的代码 public class ShowAllContactAction extends ActionSupport{ private List<Contact> resultAllContactList; private ContactServiceImpl contactServiceImpl; public void setContactServiceImpl(ContactServiceImpl contactServiceImpl){ this.contactServiceImpl = contactServiceImpl; } public String execute(){ resultAllContactList = contactServiceImpl.findAll(Contact.class); ActionContext.getContext().put("resultAllContactList" , resultAllContactList); return "SUCCESS"; } } ``` ``` 这是hibernate配置文件 <hibernate-configuration> <session-factory> <property name="show_sql">true</property> <property name="connection.url">jdbc:mysql://localhost:3306/sanke_daily</property> <property name="connection.username">root</property> <property name="connection.password">root</property> <property name="driver_class">com.mysql.jdbc.Driver</property> <property name="dialect">org.hibernate.dialect.MySQLDialect</property> <mapping resource="com/lamp/entity/Contact.hbm.xml"/> </session-factory> </hibernate-configuration> 这是struts.xml <action name="showAllContactAction" class="showAllContactAction"> <result name="SUCCESS">/jsp/contact/showAllContactSuccess.jsp</result> </action> 另外,ContactBaseDao、ContactBaseDaoImpl和ContactService、ContactServiceImpl都没有新加的特别的方法,所以都是空的

在博主认为,对于入门级学习java的最佳学习方法莫过于视频+博客+书籍+总结,前三者博主将淋漓尽致地挥毫于这篇博客文章中,至于总结在于个人,实际上越到后面你会发现学习的最好方式就是阅读参考官方文档其次就是国内的书籍,博客次之,这又是一个层次了,这里暂时不提后面再谈。博主将为各位入门java保驾护航,各位只管冲鸭!!!上天是公平的,只要不辜负时间,时间自然不会辜负你。 何谓学习?博主所理解的学习,它
程序员必须掌握的核心算法有哪些?
由于我之前一直强调数据结构以及算法学习的重要性,所以就有一些读者经常问我,数据结构与算法应该要学习到哪个程度呢?,说实话,这个问题我不知道要怎么回答你,主要取决于你想学习到哪些程度,不过针对这个问题,我稍微总结一下我学过的算法知识点,以及我觉得值得学习的算法。这些算法与数据结构的学习大多数是零散的,并没有一本把他们全部覆盖的书籍。下面是我觉得值得学习的一些算法以及数据结构,当然,我也会整理一些看过

比特币原理详解
一、什么是比特币 比特币是一种电子货币,是一种基于密码学的货币,在2008年11月1日由中本聪发表比特币白皮书,文中提出了一种去中心化的电子记账系统,我们平时的电子现金是银行来记账,因为银行的背后是国家信用。去中心化电子记账系统是参与者共同记账。比特币可以防止主权危机、信用风险。其好处不多做赘述,这一层面介绍的文章很多,本文主要从更深层的技术原理角度进行介绍。 二、问题引入  假设现有4个人
程序员接私活怎样防止做完了不给钱?
首先跟大家说明一点,我们做 IT 类的外包开发,是非标品开发,所以很有可能在开发过程中会有这样那样的需求修改,而这种需求修改很容易造成扯皮,进而影响到费用支付,甚至出现做完了项目收不到钱的情况。 那么,怎么保证自己的薪酬安全呢? 我们在开工前,一定要做好一些证据方面的准备(也就是“讨薪”的理论依据),这其中最重要的就是需求文档和验收标准。一定要让需求方提供这两个文档资料作为开发的基础。之后开发
