根据文档

Tag library descriptor files have names that use the extension .tld, and the extension indicates a tag library descriptor file. When deployed inside a JAR file, the tag library descriptor files must be in the META-INF directory, or a subdirectory of it. When deployed directly into a web application, the tag library descriptor files must always be in the WEB-INF directory, or some subdirectory of it. TLD files should not be placed in /WEB-INF/classes or /WEB-INF/lib, and must not be placed inside /WEB-INF/tags or a subdirectory of it, unless named implicit.tld and intended to configure an implicit tag library with its JSP version and tlib-version.

您可以将您的标签库放在 WEB-INF/tags 中并重命名为 implicit.tld
