在我的應用程序中，在Spring + hibernate中獲取「Closed connection」問題

我正在使用Spring和Hibernate。我正在使用JBoss EAP 6.1作爲我的應用服務器。在我的應用程序中，在Spring + hibernate中獲取「Closed connection」問題

我用春通過下面的代碼創建sessionFactory休眠：

<bean id="sessionFactory" 
     class="org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean"> 
     <property name="dataSource" ref="dataSource" /> 
     <property name="annotatedClasses"> 
      <list> 
        <!-- list of annotatedClasses --> 
      </list> 
     </property> 
     <property name="hibernateProperties"> 
      <props> 
       <prop key="hibernate.jdbc.batch_size">100</prop> 
       <prop key="hibernate.current_session_context_class">thread</prop> 
       <prop key="hibernate.dialect">${hibernate.dialect}</prop> 
       <prop key="hibernate.show_sql">${hibernate.show_sql}</prop> 
       <prop key="hibernate.hbm2ddl.auto">$(hibernate.hbm2ddl.auto)</prop> 
       <prop key="hibernate.query.factory_class">org.hibernate.hql.classic.ClassicQueryTranslatorFactory 
       </prop> 
       <prop key="hibernate.connection.autocommit">false</prop> 
      </props> 
     </property> 
</bean>

自動裝配AutowiredsessionFactory我春DAO類爲：

@Autowired 
private SessionFactory sessionFactory;

我有使用sessionFactory作爲如下得到休眠Session：

Session session = sessionFactory.getCurrentSession(); 
try { 
    session.beginTransaction(); 
    Query sqlQuery = session.createSQLQuery(query).addEntity(className); 

    if (null != arg) 
     sqlQuery.setParameters(arg, type); 

    list = sqlQuery.list(); 
    session.getTransaction().commit(); 
} catch (HibernateException ex) { 
    LOG.error(ex); 
    session.getTransaction().rollback(); 
    throw ex; 
} 
sessionFactory.getCurrentSession().close();

如上面的代碼所示，我已經關閉了，每次休眠Session。不過我正在關閉連接的問題，我跑我的申請後約半小時：

我大約每半小時一班經常面臨這樣的問題。我需要挖掘JNDI池或重新啓動JBOSS應用服務器來解決它。

任何人都可以告訴我我做錯了什麼，或者我應該採取什麼行動來解決「封閉的連接」問題？

請幫忙！

嘗試session.close（。的getCurrentSession（）。close（）方法。沒有任何意義 –

sessionFactory.getCurrentSession（）。close（）不是必需的，因爲您使用的是hibernate.current_session_context_class = thread，當事務提交或回滾時會話將自動關閉。請嘗試刪除那個 – Atul

@Atul最初我沒有使用close（）方法，並得到相同的問題。這就是爲什麼我在事務結束後添加close（）方法的原因。 – gohil90

我建議一些方法來使用會話：使用

的openSession（）：

的openSession（）打開一個新的會話，你必須關閉一旦你完成。

Session session = sessionFactory.openSession(); 

Transaction tx = null; 
try { 

    //get a transaction before performing any operations.. 
    tx = session.beginTransaction(); 

    //perform your transaction here 

    //commit the transaction as it is success. 
    tx.commit(); 
} catch (HibernateException ex) { 
    //rollback the current transaction, since a exception occurred, while performing transaction 
    if(tx!=null) 
     tx.rollback(); 
    throw ex; 
}finally{ 

    //finally close the session, since transaction is completed. 
    session.close(); 
}

使用的getCurrentSession（）：

，正如你在Hibernate配置屬性都設置hibernate.current_session_context_class到thread這意味着Hibernate會autometically關閉會話當交易完成。

//getCurrentSession() returns a session bound to a context, you don't need to close this 
    Session session = sessionFactory.getCurrentSession(); 

    Transaction tx = null; 
    try { 

     //get a transaction before performing any operations.. 
     tx = session.beginTransaction(); 

     //perform your transaction here 

     //commit the transaction as it is success. 
     tx.commit(); 
    } catch (HibernateException ex) { 
     //rollback the current transaction, since a exception occurred, while performing transaction 
     if(tx!=null) 
      tx.rollback(); 
     throw ex; 
    }

爲每ThreadLocalSessionContext的this文檔，您已通過<prop key="hibernate.current_session_context_class">thread</prop>

配置在可用性的利益，因此決定這個默認IMPL實際上產生在第一次請求，然後乾淨會話在與該會話相關的交易被提交/回滾之後它啓動

這意味着您的會話將在交易e ither承諾或回滾。

正如我假設您使用spring來管理交易，那麼設置hibernate.current_session_context_class永遠不是件好事。默認情況下，spring將使用CurrentSessionContext。

現在，您已經在current_session_context_class中使用了線程。然後爲自己的津津有味，我建議

try{ 
    //... your code 
} catch(HibernateException ex) { 
    LOG.error(ex); 
    session.getTransaction().rollback(); 
    throw ex; 
} finally { 
    if(session.isOpen()){ //I don't think this will return true in any case but still for your satisfaction you could do this 
     session.close(); 
    } 
}

更新：

從聊天使用後在Spring數據源的bean）的配置，而不是SessionFactory的

<max-pool-size>50</max-pool-size> 
<query-timeout>500</query-timeout>
