我将代码更改为使用 Jquery 表单插件，以便上传图片。我原来的形式很简单

$.ajax({
    type: "POST",
    url: "register.htm",
    data:{
            account_name: $('#regAccount_name').val(),
            pwd: MD5($('#regPwd').val()),
            fname: $('#regFname').val(),
            lname: $('#regLname').val(),
    },
    success: function(data){
        changeMainIFrame('MenuFrame.jsp?regStatus=User Successfully Registered');
    },
    error:function(e){
        console.log("sendRegistration(): " + e);
    }

});

但改成这个

    var options = { 
         beforeSend: function() 
         {
             //alert(MD5($('#regPwd').val()));
            // document.getElementById('regPwd').value = MD5($('#regPwd').val());

         },
         uploadProgress: function(event, position, total, percentComplete) 
         {

         },
         success: function() 
         {
             changeMainIFrame('MenuFrame.jsp?regStatus=User Successfully Registered');
         },
         complete: function(response) 
         {
         },
         error: function(e)
         {
             console.log("sendRegistration(): " + e);

         }

     }; 

          $("#regForm").ajaxForm(options);

但是现在我收到一个 400 Bad Request，我认为这意味着我的控制器甚至没有收到请求。这是我的控制器代码：

    @RequestMapping("/register.htm")
public String register(//   @RequestParam("regProfilePic") File pic,
                        @RequestParam("regAccount_name") String account_name,
                        @RequestParam("pwd") String pwd,
                        @RequestParam("fname") String fname,
                        @RequestParam("lname") String lname,

                       ModelMap params){

    setup();

    System.out.println("Register");
    service.registerUser(fname, lname, account_name, pwd);

    return "MenuFrame";
}

发现了问题，我需要使用 @RequestParam("regProfilePic") Multipart File pic 而不是 File pic
