请提供帮助。查看WAR文件或分解的WAR目录的内容会有所帮助 通常IntelliJ会将构建路径中的所有内容复制到WAR中的适当位置，但有时，对于某些文件类型，IntelliJ并不总是注意到更改。在本例中，这不应该是一个问题，因为它是一个类文件。我认为它认为com.test.util.ConnectionManager是一个包也很奇怪
我的建议是，在执行构建之前，确保停止tomcat，如果这没有帮助，因为我真的不认为它会检查您的WAR工件的设置，并确保它拉入了所有正确的文件。项目结构正确，intellij处理了所有事情。解析错误是必须首先更正的内部运行时错误的产物。为了找到它，我使用了tomcat日志。感谢您的帮助。我没有一起使用Intellij和Tomcat。但我不认为这是IDE的问题所在。要检查它，可以单击Build->Build Test.war分解工件。现在在proj目录中会有一个out文件夹。打开该文件夹，查看类文件是否进入工件。Out文件夹有3个子文件夹：工件、生产和测试。这些课程正在测试中。它们应该在那里吗？如果你已经创建了war文件，在artifact下，应该有一个分解的war文件。在war文件下，查找web_inf下的类。如果不起作用，请进入聊天室。我在原始文件上发布了一个指向项目结构图片的链接，但这里又是：希望这也有帮助：项目结构下的工件您需要查看部署到tomcat的生成的WAR文件或分解的WAR目录中的实际内容。从您的第二个屏幕截图来看，它看起来应该在Test\out\artifacts\Test\u war\u中，在您进行构建之后，它会爆炸。
