Spring + hibrnate =创建会话动作时出现错误

我在spring中使用hibernate。我收到以下错误而调用的getCurrentSession方法Spring + hibrnate =创建会话动作时出现错误

protected Session getCurrentSession(){ 
    return getSessionFactory().openSession(); 
}

错误：

java.lang.StackOverflowError 
    org.hibernate.engine.jdbc.internal.JdbcCoordinatorImpl.<init> (JdbcCoordinatorImpl.java:97) 
    org.hibernate.engine.transaction.internal.TransactionCoordinatorImpl.<init>(TransactionCoordinatorImpl.java:87) 
    org.hibernate.internal.SessionImpl.<init>(SessionImpl.java:254) 
    org.hibernate.internal.SessionFactoryImpl$SessionBuilderImpl.openSession(SessionFactoryImpl.java:1609) 
    org.hibernate.internal.SessionFactoryImpl.openSession(SessionFactoryImpl.java:973)

我已经搜索了很多，检查计算器给出的所有答案，但没有能够解决问题:(任何一个可以帮助我为什么我面对这样的错误。

什么是您的getSessionFactory方法？ – 2015-03-02 07:39:42

@vimal 保护的SessionFactory了getSessionFactory（）{ \t \t如果（SessionFactory的== NULL）{ \t \t \t抛出新IllegalStateException异常（ “SessionFactory的尚未使用之前设置的DAO”）; \t \t} \t \t return sessionFactory; \t} 它正在返回会话对象 – 2015-03-02 07:40:13

你确定你不会在递归通过代码吗？ – 2015-03-02 07:41:56

你的问题是，你调用下面两个函数中相互递归。

at com.nativeunlock.security.controller.LoginController.login(LoginController.java:61) 
at com.nativeunlock.security.controller.LoginController.campaign(LoginController.java:42)

你不必这样做，因为你的控制器已经与注释@Secured("ROLE_OPERATION")担保所以，如果有授权的任何要求，Spring MVC的会自动调用登录控制器。您所要做的就是在配置文件中配置逻辑控制器操作。（或批注）

删除的递归后，我读了你的真正问题的评论，这是

org.hibernate.MappingException: Named query not known: getCampaignList at org.hibernate.internal.AbstractSessionImpl.getNamedQuery(AbstractSess ionImpl.java:154) at org.hibernate.internal.SessionImpl.getNamedQuery(SessionImpl.java:137 1) at com.nativeunlock.dao.CampaignDao.getNamedQuery(CampaignDao.java:41)

这是因为该行的

public static final String GET_CAMPAIGNS_QUERY ="SiteURLs.getCampaignList";

你必须确保你试图在那里实施的逻辑是正确的。重新检查SiteURLs.getCampaignList。希望这不应该存在于应用程序中。
