试图将 JSON 数据发布到 Spring 控制器.. 根本不工作

JSP 代码：

<%@ page language="java" contentType="text/html; charset=UTF-8"
    pageEncoding="UTF-8"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>This is a project to show how to use RESTful</title>
</head>
<body>
<script type="text/javascript">var contexPath = "<%=request.getContextPath()%>";</script>
<script src="<%=request.getContextPath()%>/js/jquery.js"></script>


<script type="text/javascript">
function doAjaxPost() {  

    alert("doAjaxPost Called");

     var queryString = $('#htmlform').serialize();

       $.ajax({
            contentType : "application/json",
            dataType : 'json',
            type : "PUT",
            url : contexPath + "/service/employee",
            data : queryString, //json serialization (like array.serializeArray() etc)

            success : function(data) {
                alert("Thanks for submitting.  \n\n" + response.result);
               // response
            },
            error : function(request, status, error) {
                   alert('Error: ' + e); 
            }
        });
    }  
</script>

<H1>Add Employee</H1>

<p>
<form name="htmlform">
<table border=1>
    <thead><tr>
        <th>ID</th>
        <th>Name</th>
        <th>Email</th>
    </tr></thead>

    <tr>
        <td><input  type="text" name="ID" maxlength="5" size="3"></td>
        <td><input  type="text" name="Name" maxlength="10" size="10"></td>
        <td><input  type="text" name="Email" maxlength="10" size="10"></td>
    </tr>

</table>
<input type="button" value="Save Employee" onclick="doAjaxPost();" />
<p>
<p>
</form>
[<a href="http://localhost:8080/RESTful/service/employees">List all Employees</a> | <a href="add.jsp">Employee Form Test</a>]


</body>
</html>

控制器代码：

@RequestMapping(headers ={"Accept=application/json"}, method=RequestMethod.PUT, value="/employee" )
    public ModelAndView updateEmployee(@RequestBody Employee employee ) {
        System.out.println("in put body:");
        System.out.println("HELLO WORD" + employee.toString());

        return new ModelAndView(XML_VIEW_NAME, "object", employee);
    }

现在对于输出或错误：

2012-06-13 12:46:52,607 [http-8080-2] DEBUG org.springframework.web.servlet.DispatcherServlet - Successfully completed request

让我们看看是否有人可以让这个工作......

试着取下

headers ={"Accept=application/json"},

部分，我没有把它放在我的控制器中，它们工作正常。
