before you ask, I have included all the spring ,tiles and jstl dependency in my pom. only the form tag gives error.
在你问之前，我已经在我的 pom.xml 文件中包含了所有的 spring、tiles 和 jstl 依赖项。只有表单标签会出错。

It seems that your tag library is missing form the class-path As You don't have to configure anything. Since JSP 2.0 taglibs can be discovered automatically.
类路径中似乎缺少您的标记库，因为您无需配置任何内容。由于可以自动发现 JSP 2.0 标记库。
All You need to do is place them in WEB-INF or it's sub-folders. If you are packaging Your TLDs as JAR files, place them in WEB-INF/lib or META-INF of the JAR
您需要做的就是将它们放在 WEB-INF 或其子文件夹中。如果您将 TLD 打包为 JAR 文件，请将它们放在 JAR 的 WEB-INF/lib 或 META-INF 中
