java - Spring + hibernate = 创建 session 工厂时出错

Question

我在 spring 中使用 hibernate 。调用 getCurrentSession 方法时出现以下错误

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)

我已经搜索了很多并检查了 stackoverflow 上给出的所有答案，但无法解决问题:( 任何人都可以帮助我为什么我会遇到这样的错误。

Answer 1

您的问题是您在彼此内部递归调用了以下两个函数。

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

您不必执行此操作，因为您的 Controller 已经使用注释 @Secured("ROLE_OPERATION") 进行了保护 因此，如果有任何授权要求，Spring MVC 将自动调用登录 Controller 。您所要做的就是在配置文件中配置逻辑 Controller 的 Action 。 (或在注释中)

在您删除递归后，我阅读了您对实际问题的评论，即

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) 

这是因为这条线

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

您必须确保您尝试实现的逻辑是正确的。重新检查 SiteURLs.getCampaignList。希望应用程序中不应该存在这种情况。
