title: return new ModelAndView doesnt work
body: <p>My controller :</p>
  
  <pre><code>@RequestMapping(value="/testAdmin", method = RequestMethod.POST,consumes = "application/json")
  public ModelAndView testAdmin(@RequestBody Student student) {
      System.out.println(student.getName()+" "+student.getId()+" "+student.getLogin()+" "+student.getPassword());
      return new ModelAndView("showString","student",student.getName());
  }
  </code></pre>
  
  <p>My ajax function:</p>
  
  <pre><code> function test2(a,ob) {
      var student={
          id:ob[a].id,
          login:ob[a].login,
          password:ob[a].password,
          name:ob[a].name
      }
      $.ajax({
          type: "POST",
          contentType : 'application/json; charset=utf-8',
  
          url: "testAdmin",
          data: JSON.stringify(student),
          success: function (response)
          {
              alert("success");
          },
          error : function(xhr, status, errorThrown) {
              alert(status+" "+errorThrown.toString());
          }
      });
  }
  </code></pre>
