问题:
- 我想在 web.xml 中将 servlet 'main' 设置为欢迎文件，但它显示警告“Web 内容中不存在对 main 的文件名引用”
- 浏览器无法访问 CSS 文件，但可以访问位于同一父目录“assests”下的图像
- 我想知道这两个问题是否相关以及如何解决它们
我已经提到的内容:
- > how-to-include-external-css-file-in-jsp
- 类似的 SO 问题:1 , 2 , 3
结果:
但在这两种情况下，都不会加载任何 CSS 文件。
我已经独立测试了 Brackets 中的前端并且工作正常。

最佳答案
您应该在 <welcome-file> 中定义一个欢迎文件列表元素。所以请尝试将其更改为 <welcome-file>MainView.jsp</welcome-file>并将 jsp 文件移动到 WebContent/main/ .此外，您不需要 MainServlet.java .
关于java - Web.xml 警告 "File name references to main that does not exist in web content"，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/49800649/
