如何通過Ajax調用Spring Controller方法

Question

這是我的Controller方法：

@RequestMapping( value={"/home"},params="userAction=loadHomePage",method=Request.POST)
public String viewPage(@ModelAttribute("dataForm") formData, Model model,HttpServletRequest req)throws Exception{
...
}

如何通過ajax傳遞參數值？

這樣的事情..讓我知道是否需要進一步的指導。

var request= new XMLHttpRequest();
        request.onreadystatechange= function(){
             if (request.readyState == 4 && request.status == 200) {

             }
        };
        request.open("POST", "/home", true);
        request.setRequestHeader("Content-type", "application/x-www-form-urlencoded");
        request.send("userAction=loadHomePage");
    };

設置模型對象：

    var formData= new FormData();
    formData.append('username' , 'payal');
    formData.append('id' , 123456);
    request.send(formData);
