我被这个spring示例卡住了。我通过jsp页面从用户那里获取数据，并调用了来自控制器的save方法，并通过hibernateTemplate.save（）方法将数据存储在数据库中。我能够做到这一点，但是当我尝试通过将数据传递给jsp来显示数据时，我得到http 404错误。我的控制器类如下
CController.java
import project4.UserDAO1;
import project4.User1;
import java.util.Map;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import org.springframework.stereotype.Controller;
import org.springframework.transaction.annotation.Transactional;
import org.springframework.ui.ModelMap;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.servlet.ModelAndView;
import org.springframework.web.servlet.mvc.multiaction.MultiActionController;
import org.springframework.web.bind.annotation.ModelAttribute;
import org.springframework.validation.BindingResult;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.annotation.Qualifier;
@Controller
public class CController{
private UserDAO1 userDAO;
@Autowired
@Qualifier("myUserDAO")
private UserDAOImpl1 myUserDAO;
public void setUserDAO(UserDAO1 userDAO) {
this.userDAO = userDAO;
}
@RequestMapping(value = "/frm4/add", method = RequestMethod.POST)
public ModelAndView add( @ModelAttribute("add") User1 user,HttpServletRequest
request,HttpServletResponse response) throws Exception {
System.out.println("hai");
userDAO.saveUser(user);
System.out.println("hai");
return new ModelAndView("redirect:/list.htm");
}
@RequestMapping(params = "delete", method = RequestMethod.POST)
@Transactional
public ModelAndView delete(@ModelAttribute("delete") User1 user,HttpServletRequest
request,HttpServletResponse response) throws Exception {
userDAO.deleteUser(user);
return new ModelAndView("redirect:list.htm");
}
@RequestMapping(params = "find", method = RequestMethod.POST)
@Transactional
public ModelAndView find(@ModelAttribute("find") User1 user,HttpServletRequest
request,HttpServletResponse response) throws Exception {
userDAO.findUser(user);
return new ModelAndView("redirect:list.htm");
}
@RequestMapping(params = "update", method = RequestMethod.POST)
@Transactional
public ModelAndView update(@ModelAttribute("update") User1 user,HttpServletRequest
request,HttpServletResponse response) throws Exception {
userDAO.updateUser(user);
return new ModelAndView("redirect:list.htm");
}
@RequestMapping(value = "/list", method = RequestMethod.GET)
public ModelAndView list(HttpServletRequest request,
HttpServletResponse response) throws Exception {
ModelMap modelMap = new ModelMap();
modelMap.addAttribute("userList", userDAO.listUser());
modelMap.addAttribute("user", new User1());
return new ModelAndView("list", modelMap);
}
}
我的 hibernateTemplate 类如下
UserDAOImpl.java
package project4;
import project4.User1;
import java.util.List;
import org.hibernate.Query;
import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.hibernate.cfg.Configuration;
import org.springframework.orm.hibernate3.HibernateTemplate;
import org.springframework.transaction.annotation.Propagation;
import org.springframework.transaction.annotation.Transactional;
public class UserDAOImpl1 implements UserDAO1 {
private HibernateTemplate hibernateTemplate;
public void setSessionFactory(SessionFactory sessionFactory) {
this.hibernateTemplate = new HibernateTemplate(sessionFactory);
}
@Override
@Transactional(propagation=Propagation.REQUIRED, readOnly=false)
public void saveUser(User1 user) {
try {
System.out.println (user.getId ());
hibernateTemplate.save(user);
}catch (RuntimeException re){
throw re;
}
}
@Override
@SuppressWarnings("unchecked")
public List<User1> listUser() {
List<User1> result = hibernateTemplate.find("from User1");
System.out.println("hai");
System.out.println(result);
return result;
}
@Override
public void deleteUser(User1 user) {
hibernateTemplate.delete(user);
}
@Override
public List<User1> findUser(User1 user) {
List<User1> result =hibernateTemplate.find("from User1 where USER_ID=:"
+user.getId());
return result;
}
@Override
public void updateUser(User1 user) {
hibernateTemplate.update(user);
}
}
我试图显示列表的jsp类如下
列表.jsp
<%@ page language="java" contentType="text/html; charset=ISO-8859-1"
pageEncoding="ISO-8859-1"%>
<%@taglib uri="http://www.springframework.org/tags/form" prefix="form"%>
<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org
/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">
<title>Insert title here</title>
</head>
<body>
<form:form method="POST">
<table>
<tr>
<td width="50">Id</td>
<td width="150">First Name</td>
<td width="150">Last Name</td>
<td width="100">Money</td>
<td width="50">Currency</td>
</tr>
<c:forEach items="${userList}" var="person">
<tr>
<td><c:out value="${person.id}" /></td>
<td><c:out value="${person.name}" /></td>
<td><c:out value="${person.password}" /></td>
<td><c:out value="${person.gender}" /></td>
<td><c:out value="${person.country}" /></td>
</tr>
</c:forEach>
</table>
</form:form>
</body>
</html>
而不是使用
<c:forEach items="${userList}" var="person">
我也试过
<c:forEach items="${user}" var="person">
和
<c:forEach items="${list}" var="person">
我的spring xml类如下
<?xml version="1.0" encoding="UTF-8"?>

这只是 xml 配置文件的一部分，因为我使用了两个 xml 文件。
我可以将数据保存在数据库中，但是当我尝试显示数据时出现以下错误
type Status report
message /Spring/WEB-INF/jsp/list.jsp
description The requested resource (/Spring/WEB-INF/jsp/list.jsp) is not available.
我得到的网址为
http://localhost:8080/Spring/list.htm
需要帮助请
