This way works and with this structure you can create your own framework and do it with less boilerplate.

Sorry if some error is present, I'm writing this handly with my cellphone

Maven dependency:

    com.google.code.gson
    gson
    1.7.1

Java:

Person.java (Person Object Class)

Class Person {

    private String name;

    public String getName() {
        return this.name;
    }

    public void setName(String name) {
        this.name = name;
    }

}

PersonController.java (Person Controller)

@RestController
public class PersonController implements Controller {

    @RequestMapping("/person")
    public ModelAndView handleRequest(HttpServletRequest arg0, HttpServletResponse arg1) throws Exception {
        Person person = new Person();
        person.setName("Person's name");
        Gson gson = new Gson();

        ModelAndView modelAndView = new ModelAndView("person");
        modelAndView.addObject("person", gson.toJson(person));

        return modelAndView;
    }
}

View:

person.jsp

    
        
        
        
    
    
        
Person/h1>
             
    

Javascript:

personScript.js

function parseJSON(data) {
    return window.JSON && window.JSON.parse ? window.JSON.parse( data ) : (new Function("return " + data))(); 
}

$(document).ready(function() {
    var personJson = $('#person');
    person = parseJSON(personJson.val());
    alert(person.name);
});
