Question

我正在尝试对数据库进行查询，我得到了这个：

java.lang.IllegalArgumentException异常： org.hibernate.hql.internal.ast.QuerySyntaxException：generalsetup is 未映射[FROM generalsetup] org.hibernate.internal.ExceptionConverterImpl.convert（ExceptionConverterImpl.java:133） org.hibernate.internal.ExceptionConverterImpl.convert（ExceptionConverterImpl.java:157） org.hibernate.internal.ExceptionConverterImpl.convert（ExceptionConverterImpl.java:164） org.hibernate.internal.AbstractSharedSessionContract.createQuery（AbstractSharedSessionContract.java:670） org.hibernate.internal.AbstractSharedSessionContract.createQuery（AbstractSharedSessionContract.java:103） org.apache.jsp.Environments_jsp._jspService（Environments_jsp.java:188） org.apache.jasper.runtime.HttpJspBase.service（HttpJspBase.java:70） javax.servlet.http.HttpServlet.service（HttpServlet.java:731） org.apache.jasper.servlet.JspServletWrapper.service（JspServletWrapper.java:439） org.apache.jasper.servlet.JspServlet.serviceJspFile（JspServlet.java:395） org.apache.jasper.servlet.JspServlet.service（JspServlet.java:339） javax.servlet.http.HttpServlet.service（HttpServlet.java:731） org.apache.tomcat.websocket.server.WsFilter.doFilter（WsFilter.java:52）

重要提示：我可以写入数据库，但无法阅读。

这是我的代码，试图从中获取一个列表（generalsetup下有一个错误标记：

SessionFactory factory = HibernateUtil.GetSessionFactory();
Session hibernateSession = factory.openSession();
Transaction tx = null;
try {
    tx = hibernateSession.beginTransaction();
    List environments = hibernateSession.createQuery("FROM generalsetup").list();
    for (Iterator iterator = environments.iterator(); iterator.hasNext();) {
        Environment environment = (Environment) iterator.next();
        System.out.println(environment.getName());
    }
    tx.commit();
} catch (HibernateException e) {
    if (tx!=null) tx.rollback();
    e.printStackTrace();
} finally {
    hibernateSession.close();
}

我的GeneralSetup.hbm.xml
