以下内容对我有用.从上面的YouTube视频中可以看到，我已经对其进行了测试，并且可以正常运行.

The following worked for me. As you can see from the above YouTube video, I already tested it and it works.

目录结构:

确保您的目录结构与此匹配.

Make sure your directory structure matches this.

web.xml:

一些注意事项: <url-pattern>应该为<url-pattern>/<url-pattern>，因为当应用程序首次启动时，它会尝试连接到localhost:8080/YourAppName/，而不是localhost:8080/YourAppName/homePage.

A few things to note: The <url-pattern> should be <url-pattern>/<url-pattern> because when the app first starts up, it tries to connect to localhost:8080/YourAppName/ and not localhost:8080/YourAppName/homePage.

HelloController.java:

HelloController.java:

HelloWeb-servlet.xml

HelloWeb-servlet.xml
