Question

我试图通过AJAX将JSon格式的对象发送到我的Java后端，但是我没有成功。我想知道语法是否正确。

＆＃13;

<!DOCTYPE html>
<html>
<head>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.2.1/jquery.min.js"></script>
<script src="scripts/jquery.min.js.download"></script>
 <script src="scripts/jquery.imagemapster.js.download"></script>
<script>

$(document).ready(function(){
    $("button").click(function(){
	var myJSon = {"name":"Jo","age":30,"city":"Ny"};
     
       $.ajax({
		type: "POST",
		url: 'http://localhost:8080/Servidor/server',
		//contentType: "application/json;charset=utf-8",
		dataType: "json",
		data: JSON.stringify(myJSon),
		success: function (data){
		   alert('Sucess');
	        },
		error: function () {
		   alert('Error');
	        }
       });
    });
});
</script>
</head>
<body>

<button>Send an HTTP POST request to a page and get the result back</button>

</body>
</html>

＆＃13;

如果未注明行contentType: "application/json;charset=utf-8"，我会在后端收到以下错误：INFO: Could not find grammar element for class java.lang.String

语法是否正确？错误可能来自后端本身吗？

P.S。：对不起，我的英文不好

你的代码很好，你刚刚在AJAX调用上拼错了“成功”（你需要2个字母c而不是1个）。因此，将sucess: function(data){...}替换为success: function(data){...} https://jsfiddle.net/stephentillman/aow5pah2/

通过AJAX将JSon对象发布到Webservice
