java - Apache Tiles 3 JSP 异常

Question

我在使用 Apache Tiles 3 时遇到了一个奇怪的问题。它之前的设置和工作都很好，但是下面的项目进行了一些重构，现在它完全坏了。它总是返回带有堆栈跟踪的 500 内部服务器错误(包括在下面)。更改了项目名称、文件夹结构、一些文件夹名称和一些文件名称，以满足项目的标准。

奇怪的是路径是绝对正确的，这似乎就是它所提示的。下面这行我完全不明白。有什么想法吗？

java.lang.NoClassDefFoundError: org/apache/jsp/WEB_002dINF/views/tiles/shared/header_jsp (wrong name: org/apache/jsp/WEB_002dINF/Views/Tiles/Shared/Header_jsp)

来自异常堆栈跟踪

Caused by: java.lang.NoClassDefFoundError: org/apache/jsp/WEB_002dINF/views/tiles/shared/header_jsp (wrong name: org/apache/jsp/WEB_002dINF/Views/Tiles/Shared/Header_jsp)

header.jsp JSP 文件的编译类文件似乎丢失了。这可能意味着 Servlet 容器未能生成它，并且可能由于多种原因而发生。

从您评论中的提示来看，这似乎只是一个文件命名问题。您可能可以通过清理 tomcat 的工作目录和您的 Web 应用程序的工作目录来解决它。
