休眠事务已处于活动状态

Question

我目前有两个问题，但先解释一下情况：

我有一个 Struts2 Hibernate 项目，然后我创建了一个类名 class CreateUserView(generics.CreateAPIView): permission_classes = [permissions.AllowAny] def create(self, request, *args, **kwargs): serializer = CreateUserSerializer(data = request.data) if serializer.is_valid(raise_exception=True): serializer.save() return Response(serializer.data, status=status.HTTP_201_CREATED) return Response(serializer.errors, status=status.HTTP_400_BAD_REQUEST) 的拦截器堆栈。每次用户调用操作时，我都会调用该拦截器堆栈。

现在我的问题：

• 我第一次启动 Web 应用程序时，它会尝试重新创建所有表，而这些表已在数据库中创建。
• 第二个问题是，在我的 Web 应用程序尝试重新创建所有表后，该操作不会转到我的控制器，并且它一直说事务已经处于活动状态。

我的代码：

HibernateSessionInterceptor：

HibernateSessionInterceptor

课程控制器：

public class HibernateSessionInterceptor extends AbstractInterceptor {

    /**
     * 
     */
    private static final long serialVersionUID = -4986134131287730428L;

    /**
     * @see com.opensymphony.xwork2.interceptor.AbstractInterceptor#init()
     */
    @Override
    public void init() {
        DAOFactory.setTheFactory(DAOFactories.HIBERNATE.getTheFactory());
        super.init();
    }

    /**
     * @see com.opensymphony.xwork2.interceptor.AbstractInterceptor#destroy()
     */
    @Override
    public void destroy() {
        DAOFactory.setTheFactory(null);
        super.destroy();
    }

    /**
     * @see com.opensymphony.xwork2.interceptor.AbstractInterceptor#intercept(com.opensymphony.xwork2.ActionInvocation)
     */
    @Override
    public String intercept(ActionInvocation invocation) throws Exception {
//      if(HibernateSessionManager.getSessionFactory().getCurrentSession().isOpen()) {
//          HibernateSessionManager.getSessionFactory().getCurrentSession().close();
//      }
        HibernateSessionManager.getSessionFactory().getCurrentSession().beginTransaction();
        
        return Action.SUCCESS;
    }

}

struts.xml（资源文件夹）：

public class CourseController {
    private static final long serialVersionUID = 1L;
    
    public String courseCode;
    public String schoolName;
    public String schoolNameWithoutArticle;
    public String coursePrice;
    public String secondCoursePrice;
    public String email;
    public int maximumRegistrations;
    public int currentRegistrations;

    public String execute() throws Exception {
        System.out.println(schoolName);
        DAOFactory.getTheFactory().getCourseDAO().findById("ADNM10005").delete();
        return "success";
    }
// NOT INCLUDED GETTERS AND SETTERS
}
