Question

Inside Controller I need to get a rendered string and do some actions with it. This string has to be rendered out of a view. Is there a simple way of doing it?

Clarification:

I have controller

@RequestMapping(value = "/")
@ResponseBody
public String renderString() {

//I NEED TO RENDER SOME CONTENT I SAVED IN A VIEW
//I DONT WANT TO RETURN THIS CONTENT BACK TO THE BROWSER
//INSTEAD I WANT TO LETS SAY SEND CONTENT VIA EMAIL

ModelAndView view = new ModelAndView("email_template", Model);

**//QUESTION IS HERE, HOW DO I GET RENDERED STRING OUT OF VIEW/MODEL?
String emailText = view.render(); ??????????** 

...sendEmail(emailText);


return "Email send";
}

Hope is more clear now

As Japs told you, I’m not sure to really understand your question, but I’ll go for what I think “out of a view” means.

With Spring you can add the annotation @ResponseBody to your Controller. The String returned by the method will then be the only content of the response.

Example:

@RequestMapping(value = "/")
@ResponseBody
public String renderString() {
    return "Rendered String";
}

You will get “Rendered String” at screen.
