How to setup Tomcat 9 server to run it on Intellij IDEA UE (macOS)
问题
我复制了这个Java项目并像往常一样设置了Tomcat 9。但是,当我启动服务器时,我收到HTTP状态404
错误。
我需要更新我的Tomcat / IntelliJ IDEA的哪个部分?我正在使用macOS上的IntelliJ Ultimate,搭配Tomcat 9和10(都安装了,但使用9),我的设备是MacBook Air(M1,2020)。
以下是我的项目的一些相关截图:

英文:
I forked this Java Project and set up Tomcat 9 as usual. But, when I start the server running, I get HTTP Status 404
.
Which part of my Tomcat / IntelliJ IDEA, do I have to update? I'm using IntelliJ Ultimate with Tomcat 9 and 10 (both installed, but using 9) on macOS - MacBook Air (M1, 2020).
Here are some relevant screenshots from my project:

在你的派生样本项目的src/main/webapp/index.jsp
文件中,包含了以下部分:
<jsp:forward page="/login"/>
实际上,你已经成功访问了首页,并且它会重定向到项目中不存在的/login
页面,因此会出现404错误。
但是你的项目中有一个src/main/webapp/login.jsp
文件,所以你可以访问http://localhost:8080/xxxx/login.jsp
。
如果你将<jsp:forward page="/login"/>
更改为<jsp:forward page="/login.jsp"/>
,也会有帮助。
英文:
In your forked sample project's src/main/webapp/index.jsp
file, it contains this part:
<jsp:forward page="/login"/>
Actually, you have already accessed the index page successfully, and it redirects to the /login
page which does not exist in your project so 404 here.
But you have an src/main/webapp/login.jsp
file in this project, so you could access the http://localhost:8080/xxxx/login.jsp
.
If you change the <jsp:forward page="/login"/>
to <jsp:forward page="/login.jsp"/>
, it would help too.

在部署选项卡中的应用上下文中添加"/"(斜杠)应该可以解决问题。
如果这不能解决问题,然后转到此页面。
英文:
Adding "/" (slash) to the Application context in the deployment tab should do it.
If that doesn't solve it, then go to this page.
