最简单的post和ajax传对象

---------------post----------------------
$.post("testSendValue/sendValue",scatalog
    ,function(data){
             alert(data);
});
-------------ajax------------------------
var scatalog = new Object();
     scatalog.id =3;
     scatalog.pId = 5;
     $.ajax({
         type : 'POST',
         url : 'testSendValue/sendValue',
         data :scatalog ,
         success: function(data){
             alert(data);
             } 
});
------------后台-------------------------
@RequestMapping("sendValue")
    @ResponseBody
    public String test(StandardCatalog scatalog){
        return "succeed";
    }
