Question

我在JBoss服务器上运行一个应用程序，它是使用struts2＆amp;休眠。但我在LoginDAOImpl类的getEmployee方法中遇到问题。代码如下： -

@SuppressWarnings("unchecked")
public List<UserView> getEmployee(String empId) {
    Session session = null;
    List<UserView> list = null;
    try {
        System.out.println("in LoginDAOImpl getEmployee : 1 ");
        session = HibernateSessionFactory.getSession();
        System.out.println("in LoginDAOImpl getEmployee : 2 " + session);
        String str = "from UserView  where empId='" + empId + "'";
        list = session.createQuery(str).list();
        System.out.println("LoginDAOImpl.getEmployee()::" + empId);
    } catch (HibernateException e) {
        e.printStackTrace();
    } finally {
        HibernateSessionFactory.closeSession();
    }
    return list;
}

配置文件如下： -

<?xml version='1.0' encoding='UTF-8'?>
<!DOCTYPE hibernate-configuration PUBLIC
          "-//Hibernate/Hibernate Configuration DTD 3.0//EN"
          "http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd">

</session-factory>

</hibernate-configuration>


On Console Iam getting "in LoginDAOImpl getEmployee : 1 " but i am not getting "in LoginDAOImpl getEmployee : 2 ".That means it is not able to find Hibernatesessionfactory class.But I have included Hibernatesessionfactory in my path. I have included jars for Hibernate :- hibernate3.jar,hibernate-annotations-3.2.1.ga.jar,hibernate-annotations.jar,hibernate-commons-annotations.jar,hibernate-entitymanager.jar,hibernate-valid

Answer 1

这是在您的开发环境中运行吗？该类是否编译正确。我想知道问题是由环境，配置或代码引起的。

Answer 2

您需要检查的一些可能解决问题的方法是， 1.检查环境设置，包含路径等 2.检查进口报表 3.确保HibernateSessionFactory属于所需的类，因为它可能来自其他一些导入的类或jar。
4.构建项目并检查其构建类目录中是否生成了.class文件。
5.debug HibernateSessionFactory.getSession（）方法并查找错误原因回复这个问题的状况。
希望它能解决你的问题。
