出现一个错误，原因是因为前面我们设置userID为整数类型，而这里的expression是字符串类型，所以要修改一下TestAction.java文件：
package emptyprj;
import emptyprj.TestDAO;
import ng.reflect.InvocationTargetException;
import java.util.Locale;
// 变量定义：
private Log log = LogFactory.getLog("org.apache.struts.webapp.Example" );
public TestAction() {
}
//函数定义：
public ActionForward execute(ActionMapping mapping,
ActionForm form,
HttpServletRequest request,
HttpServletResponse response)
throws Exception
{
// Extract attributes and parameters we will need
Locale locale = getLocale(request);
MessageResources messages = getResources(request);
HttpSession session = request.getSession();
TestForm m_TestForm = (TestForm) form;
TestDAO m_TestDAO = TestDAO.getInstance(); //定义Hibernate__DAO对象，
用于实现数据库的各种操作
String action=request.getParameter("action"); //动作类型
String search=request.getParameter("search"); //数据库查找方式
String expression=request.getParameter("expression"); //参数，这里用于保存记录（行）的ID数据
if(action==null)action="find";
if(search==null)search="UNsearch";
if(expression==null)expression="";
expression=toChinese(expression); //处理中文问题,实现编码转换
/////////
if("delete".equals(action)) //删除记录操作
{
Test m_Test= new Test();
//<delete>
m_Test.setUserID(expression);
//</delete>
m_TestDAO.removeID(m_Test);
}
////////////
if("update".equals(action)||"insert".equals(actio n)) //更新、添加记录操作
{
Test m_Test= new Test();
//<update>
m_Test.setUserID(m_TestForm.getUserID( ));
m_Test.setUsername(m_TestForm.getUsern ame());
m_Test.setPassword(m_TestForm.getPassw ord());
m_Test.setRole(m_TestForm.getRole());
//</update>
if("update".equals(action)) //调用DAO 对象更新记录
m_TestDAO.update(m_Test,expressi on);
if("insert".equals(action)) //调用DAO 对象添加记录
m_TestDAO.create(m_Test);
}
///////////////HQL_查找数据库
String sql="from emptyprj.Test Test";
（3）启动调试状态下的服务器：
输出栏中输出如下提示信息：
