Question

我在安装Spring Security之前有一个控制器映射。我正在学习MVC和Spring。

现在我收到一个PageNotFoundException，说无法找到路径。如果你看到我的控制器它映射到/ user和方法来获取/ list中的数据。

我不确定问题是什么。任何帮助都会有用。

以下是信息：

MVC-调度-servlet.xml中

UserController.java

 @Controller
 @RequestMapping("/user")
 public class UserController {

@RequestMapping(value = "/addUser", method = RequestMethod.GET)
public String getAddUserPage(ModelMap model) {

    return "add";

}


// get all users

@RequestMapping(value = "/list", method = RequestMethod.GET)
@ResponseBody
public  List<Contact> listCustomer( ModelMap model) {

    List<Contact> users = Datastore.query(Contact.class).asList();

    model.addAttribute("userList", users);

    return users;

 }
}

LoginController.Java [这是第一个被调用的控制器]

@Controller
public class LoginController {

private static final Logger log = Logger.getLogger(LookupUserServlet.class
    .getName());

@RequestMapping(value = "/", method = RequestMethod.GET)
public String landing() {
    return "landing";
}


@RequestMapping(value = "/home.jsp", method = RequestMethod.GET)
public String home() {

    return "home";
}

@RequestMapping(value = "/disabled.jsp", method = RequestMethod.GET)
public String disabled() {
    return "disabled";
}

@RequestMapping(value = "/logout.jsp", method = RequestMethod.GET)
public void logout(HttpServletRequest request, HttpServletResponse response)
        throws IOException {
    request.getSession().invalidate();

    String logoutUrl = UserServiceFactory.getUserService().createLogoutURL(
            "/loggedout.jsp");

    response.sendRedirect(logoutUrl);
}

@RequestMapping(value = "/loggedout.jsp", method = RequestMethod.GET)
public String loggedOut() {
    return "loggedout";
}


@RequestMapping("/ListUsers")
public String ListUser() {

    return "users/ListUsers";

}

@RequestMapping("/SendAll")
public String SendAll() {

    return "sendmessage/SendAll";

}

在我的ListUsers方法中，我应该重定向到名为UserController的控制器吗？

Answer 1

您的清单有额外/

@RequestMapping(value = "/list/", method = RequestMethod.POST)

将其更改为

@RequestMapping(value = "/list", method = RequestMethod.POST)

假设您提交的表单指向“/ list”

Answer 2

所以我将URI映射移动到名为LoginController的控制器，并且请求有效。我现在的问题是，为什么我的UserController没有被拿起来。我在所有基础软件包和我的控制器中都进行了上下文扫描扫描。

有没有人有想法？

Answer 3

经过更多调查。我相信Eclipse对Java类做了些什么。当我查看Java类以及Eclipse如何对其进行注释时，它没有相应的＆＃34;曲折的＆＃34;这表明了班上的承包商。

我创建了另一个Java类并添加了代码并且它运行正常。
