首次登錄：HTTP狀態500 - 請求處理失敗;嵌套的異常是org.springframework.transaction.CannotCreateTransactionException

我已經用Spring，Hibernate和MySQL製作了一個Java webapp。它運行正常，但在第一次嘗試連接時，出現以下錯誤：首次登錄：HTTP狀態500 - 請求處理失敗;嵌套的異常是org.springframework.transaction.CannotCreateTransactionException

HTTP Status 500 - Request processing failed; nested exception is org.springframework.transaction.CannotCreateTransactionException: Could not open Hibernate Session for transaction; nested exception is org.hibernate.TransactionException: JDBC begin failed:

它只發生在第一次嘗試中。如果我重新加載頁面或嘗試再次識別，它會正確運行。

我在互聯網上搜索了很多可能的解決方案，我嘗試了其中的一些，但它還沒有運行。昨天我嘗試了一個似乎是正確的解決方案，當我上傳它時，它運行良好，但今天錯誤再次出現，所以我不知道該怎麼辦。

這些都是我的配置文件：

調用數據庫，我這樣做（我把類的例子）： EquipoDaoImp.java

@Repository(value = "equipoDao") 
public class EquipoDaoImp implements EquipoDao { 

    private final SessionFactory sessionFactory; 

    @Autowired 
    public EquipoDaoImp(SessionFactory sessionFactory) { 
     this.sessionFactory = sessionFactory; 
    } 

    @Override 
    @Transactional(readOnly = true) 
    public Integer getIdEquipo(String nombreUsuario) { 
     return (Integer) this.sessionFactory.getCurrentSession() 
       .createQuery("from Equipo e order by e.id") 
         .uniqueResult(); 
    } 

}

任何想法，爲什麼它發生？

看來，MySQL或防火牆殺死被掛在你的JDBC連接池長時間不活動的連接：

com.mysql.jdbc.exceptions.jdbc4.CommunicationsException: Communications link failure 
The last packet successfully received from the server was 4,665,488 milliseconds ago.

檢查的wait_timeout關於MySQL的價值。

你可以玩DBCP settings validationQuery，testOnBorrow和testWhileIdle。

A中的confuguration那就是「帶和吊帶」，並以犧牲性能爲代價可能會解決你的問題是：

<bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource" destroy-method="close"> 
    <property name="driverClassName" value="${jdbc.driverClassName}"/> 
    <property name="url" value="${jdbc.url}"/> 
    <property name="username" value="${jdbc.username}"/> 
    <property name="password" value="${jdbc.password}"/> 
    <property name="validationQuery" value="SELECT 1"/> 
    <property name="testOnBorrow" value="true"/> 
</bean>

以上將每次從池中借用時間的測試連接。

我把這個你說的。我試圖進入，我可以在第一時間進入。但也許明天我會確定如果這是我第一次再次入場的正確解決方案。謝謝！ :) –

好的。 2天后，它運行正常。這是問題所在。謝謝：） –
