我有一个百万美元形式，可以通过spring控制器验证来自数据库的数据，数据验证工作正常，但是当我想在验证后验证不同的数据时它会给我一个错误400，没有错误在堆栈跟踪中，所以我不知道如何解决这个问题，可能是因为我的逻辑错误，因为我是新手。
这里的表格是
<form th:name="memberRkiForm" id="memberRkiForm" th:action="@{/}" th:object="${formResult}"
method="POST">
<div>
<table id="form">

单击“验证”按钮时，表单操作将转到弹出控制器，该控制器将卡号检查到数据库（checkCardNum），然后如果数据验证返回true，则表单将自动填充与该数据相关的数据。卡号，表格填写完数据后，我想用另一张卡号（不同于第一张经过验证的卡号）检查验证，但它给我一个错误400.
这是我的控制器

也许有人可以帮我解决问题， Thx提前..（对不起我的英语不好）
