我在隐藏输入时遇到了同样的问题,但没有找到解决方案,而是手动设置字段的“id”和“name”属性,并忽略了th:field。您是如何定义表单的?您定义了什么对象?这个对象有
密钥
和秘密
属性吗?如果您已将这些值放入模型映射中,则应使用${key}
和${secret}
@ThomasPawlitzki引用它们。请参见上文更新的帖子。还请注意,仅使用th:field
即可正确传递所有其他参数。您是否设置了字段key
和secret
?那么如何在MVC处理程序中检索值呢?@ThomasPawlitzki再次更新了帖子。请参阅。html中是否有值发送到浏览器?在那里,您应该可以看到具有值属性的隐藏字段。但是值是否已传递?如果保留“value”属性,它将被传递(至少对我有效:)。IIRC表单中所有有名称的内容都会在提交时传递,但我可能会在这里混淆名称和id。使用spring和thymeleaf?你确定吗?)是的。我的代码看起来是这样的:并且它被正确地提交了。啊,好吧,但是如果值是html静态的呢?
