Can we add our own custom Controllers in Spring MVC application which is using TRIDION

Question

I am pretty new to Tridion so my question may be basic but I have not found an answer yet. I have a Tridion based Spring MVC project which is working fine and fetching content from SDL Tridion .

Now I am adding a new Controller class which should display a page which has a form and upon submission page should submit the data to another Java method. Just like any other normal Spring MVC application.

But the Tridion project doesn't like that. Do we need to anything special to register our mapping, is it supported in Spring MVC project of Tridion.

Here is my Controller Class

 @Controller
public class UserFormController {
    @RequestMapping(value = "/example/user", method = RequestMethod.GET)
    public ModelAndView showForm() {
        System.out.println("#############Hellooo I was here#################");
        return new ModelAndView("user", "user", new UserForm());
    }
    @RequestMapping(value = "/user", method = RequestMethod.GET)
    public ModelAndView showFormUser() {
        System.out.println("#############Hellooo I was here too#################");
        return new ModelAndView("user", "user", new UserForm());
    }

    @RequestMapping(value = "/example/addUser", method = RequestMethod.POST)
    public String submit(@ModelAttribute("user")UserForm user, 
      BindingResult result, ModelMap model) {
        if (result.hasErrors()) {
            return "error";
        }
        model.addAttribute("name", user.getFirstName());
        model.addAttribute("email", user.getEmail());
        return "userView";
    }
}

This is what I see my Logs

There is no mapping to /user or /example/user. Can somebody please explain what needs to be done differently for Tridion application ? Is there any tutorial for this..Any help is appreciated

Answer 1

It seems you use dd4t 2. In the dispatcher-servlet.xml file you need to add your controller:

<!-- Configure me: change this to the base-package 
     where your overridden controllers are -->
<context:component-scan 
  base-package="org.dd4t.test.web.controller,my.base.package"
  annotation-config="true"/>

For my.base.package use the base namespace your UserFormController is in.
