我的表单有问题。当我使用按钮时，它使用 post 方法发送到当前地址，而不是表单中指定的方法。我不知道这种形式有什么问题。我真的很感激一些帮助。

<form th:action:="@{/shoppingCart/addItem}" method="post">
    <input hidden="hidden" th:value="*{book.id}"/><!--both name and value are taken care of by that syntax -->

        <div class="col-xs-3">
            <a th:href="@{/bookshelf}">Back to book list. </a><br/>

最佳答案

看起来您有一个拼写错误:

th:action:="@{/shoppingCart/addItem}"
