我遇到了一个奇怪的问题——当我把我的应用程序JAR 放到WEB-INF/lib目录中时,它不起作用。但是,当创建WEB-INF/类目录并在那里解开我的JAR时,它的工作效果很好。
有帮助吗?
你所描述的行为是想要的 而且是完全自然的
/WEB-INF/class 必须包含您的 Java EE 应用程序的分类。 如果您使用 IDE 来包装 WAR (Web Application Archive) 文件, 您就会注意到您的应用程序被放在那里 。 WAR 文件是通常部署的方式 。
正如名称上所说的,/WEB-INF/lib 是librariary 的默认搜索路径。图书馆通常作为 JAR 文件分发,因此这些图书馆被放入lib 目录。
最后,现在很明显的是,为什么如果你因为两个错误而将您的应用程序 JAR 放在 lib 目录中,它就不会起作用,因为有两个错误,即您的文件不应该被包装在任何档案库中,而 lib 目录是为(包装的)图书馆准备的。
您是否尝试将 JAR 文件拖放到 WEB- INF/ lib 目录中? 请确认它复制, 而不是将整个 JAR 提取到文件夹中 。
