index.html not displaying for my WebApp (Tomcat 7 in Eclipse)
提问by Neilos
I have Tomcat 7 with Servlet 3.0 running in Eclipse.
我在 Eclipse 中运行了带有 Servlet 3.0 的 Tomcat 7。
Under my WEB-INF folder I placed two files, web.xml and index.html. The web.xml defines the welcome-file as index.html however when I go to
在我的 WEB-INF 文件夹下，我放置了两个文件，web.xml 和 index.html。web.xml 将欢迎文件定义为 index.html 但是当我去
http://localhost:8080/WebApp/
I get a 404.
我得到一个 404。
Strange thing is that I have a servlet defined as /login and when I go to
奇怪的是，我有一个定义为 /login 的 servlet，当我去
http://localhost:8080/WebApp/login
I can see and use the servlet (I can debug it and see my doGet() request)
我可以查看和使用 servlet（我可以调试它并查看我的 doGet() 请求）
I have no idea why I cannot see the welcome file, It did work a while ago but I have made some changes since then, I changed how I connect to a database by setting up a Connection Pool as Tomcat starts but this shouldn't have affected much. Not quite sure where to look next, catalina.out gives no hints.
我不知道为什么我看不到欢迎文件，它在不久前确实有效，但从那时起我做了一些更改，我通过在 Tomcat 启动时设置连接池来更改连接到数据库的方式，但这不应该影响很大。不太确定下一步该往哪里看，catalina.out 没有给出任何提示。
Can anyone see why my welcome file is not functioning as I want? Any help appreciated :)
任何人都可以看到为什么我的欢迎文件没有按我想要的方式运行？任何帮助表示赞赏:)

Ahh my last comment just made me realise something. I was being a bit silly. I simply had my index.html in the wrong location, it shouldn't be under WEB-INF but under WebContent (the parent directory of WEB-INF). The 404 was in fact the massive hint, everything was working correctly except me! Doh!
啊，我的最后一条评论让我意识到了一些事情。我说的有点傻。我只是将我的 index.html 放在错误的位置，它不应该在 WEB-INF 下，而是在 WebContent（WEB-INF 的父目录）下。404 实际上是一个巨大的提示，除了我之外，一切正常！呸！

In your web.xml file you should have something like this :
在您的 web.xml 文件中，您应该有这样的内容：
<servlet-mapping>
<servlet-name>Faces Servlet</servlet-name>
<url-pattern>*.xhtml</url-pattern>
<url-pattern>*.jsf</url-pattern>
<url-pattern>/faces/*</url-pattern>
</servlet-mapping>
This way you're mapping url patterns to servlets. In this example, you access index.xhtml, index.jsf or .../faces/index
这样您就可以将 url 模式映射到 servlet。在本例中，您访问 index.xhtml、index.jsf 或 .../faces/index
