Supporting multiple content types in a Spring-MVC controller

Question

A Rails controller makes it very easy to support multiple content types.

respond_to do |format|
  format.js { render :json => @obj }
  format.xml
  format         


        

Answer 1

In Spring 3, you want to use the org.springframework.web.servlet.view.ContentNegotiatingViewResolver.

It takes a list of media type and ViewResolvers. From the Spring docs:

The Controller:

import org.springframework.stereotype.Controller;
import org.springframework.ui.ModelMap;
import org.springframework.web.bind.annotation.RequestMapping;

@Controller
public class BlogsController {

    @RequestMapping("/blogs")
    public String index(ModelMap model) {
        model.addAttribute("blog", new Blog("foobar"));
        return "blogs/index";
    }    
}

You'll also need to include the Jackson JSON jars.
