我正在为 CRUD 尝试一些 spring 示例。现在我能够成功地将数据保存在数据库中，但是当我尝试通过 jsp 显示它时，我无法这样做......我的 spring 控制器类如下
CController.java
@Controller
public class CController{
private UserDAO1 userDAO;
@Autowired @Qualifier("myUserDAO")
private UserDAOImpl1 myUserDAO;
@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);
return new ModelAndView("redirect:list.htm");
}
@RequestMapping(params = "/frm/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 = "/frm/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 = "/frm/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");
}
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jsp文件如下
列表.jsp
<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="${list}" var="person">
<tr>
<td><c:out value="${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>
我的控制器配置文件如下

我有三个 xml 文件，一个用于经理级别，另一个用于 dao，另一个是应用程序上下文。上面是经理级别 xml
当我尝试在jsp中显示数据时，出现以下错误
HTTP Status 404 -
--------------------------------------------------------------------------------
type Status report
message
description The requested resource () is not available.
我得到的网址为
http://localhost:8080/Spring/frm4/list.htm
当我应该得到的实际网址是
http://localhost:8080/Spring/list.htm
frm4 是我将数据传输到控制器类的另一个 jsp 表单。
有人可以帮忙吗？
