ajax提交json對象到服務器

$.ajax({
    type: "POST",
    url: "saveReceipt.do",
    data: JSON.stringify(object),//將對象序列化成JSON字符串
    dataType:"json",
    contentType : 'application/json;charset=utf-8', //設置請求頭信息(必須)
    success: function(data){
     alert(data);
    },
    error: function(res){
        alert("系統錯誤,保存失敗!");
    }
});

服務器端通過@RequestBody註解封裝對象

@RequestMapping(value = "updateObject", method = RequestMethod.POST)
@ResponseBody
public JsonMessage updateObject(@RequestBody XXX xxxObj) {
    ...//省略更新代碼
    return new JsonMessage(true,"更新成功");
}
