我有一个弹簧标签表格绑定到我的一个实体。
当我刚发布表格时;一切都很好。
现在;我正在迁移我的应用程序以保持100％的安静
我刚刚使用spring标签离开了表单，并使用Ajax JQuery将数据发布到我的控制器。
问题：
表单很复杂，我的对象“申请人”包含其他嵌套对象“联系人”＆amp; “教育”
jQuery正在将表单序列化为JSON，但是，它创建了一个名为contact:{email="xx@xx"}的简单原语，而不是创建一个名为contact的json元素并将其所有原语放在其中contact.email"xx@xx"。
因此;我发现控制器中的元素联系为null。 （在控制器端正确接收lastName和firstName这样的简单基元。）
有人知道如何解决这个问题，或者是否有任何jQuery API会将复杂的spring表单序列化为JSON？
感谢。

JSON.stringify仅序列化一个简单的对象/数组。为了序列化具有嵌套对象的复杂对象，您可以考虑使用第三方库。以下是您可能会找到的https://github.com/yeoman/stringify-object
之一关于其用法的一个例子。
var obj = {
foo: 'bar',
'arr': [1, 2, 3],
nested: { hello: "world" }
};
var pretty = stringifyObject(obj, {
indent: ' ',
singleQuotes: false
});
console.log(pretty);
/*
{
foo: "bar",
arr: [
1,
2,
3
],
nested: {
hello: "world"
}
}
*/
