Spring URI - Controller Mapping - spring

Question

I have a controller mapping that worked before I put in Spring Security. I am learning MVC and Spring.
Now I get a PageNotFoundException saying that path cannot be found. If you see my controller it maps to /user and the method to get the data in /list.
I'm not sure what the issue is. Any help would be useful.
Here is the information:

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 [This is the first controller that gets called]
#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";
}
In my ListUsers method should I redirect to the controller called UserController?

Answer 1

Your list has extra /
#RequestMapping(value = "/list/", method = RequestMethod.POST)
Change it to
#RequestMapping(value = "/list", method = RequestMethod.POST)
This is on assumption that your form being submitted is pointing to "/list"

Answer 2

So I moved the URI mapping to my controller called LoginController and the request worked. My question is now, why is my UserController not getting picked up. I have the context base-scan scanning in all the base packages and my controller.
Does anyone have an idea?

Answer 3

Upon more investigation. I believe that Eclipse did something to the Java class. When I looked at the Java class and how Eclipse annotates it, it did not have a corresponding "twisty" that shows a contractor of the class.
I created another Java class and added the code and it worked appropriately.
