Have you tried playing with URL Rewrite on Tomcat?

Tomcat adds a trailing slash automatically. Just test it with the example application supplied with Tomcat..

If - due to some special configuration - it does not, I'd write a Filter that examines the query string and redirects as needed by the application. Many times this is needed anyways (doing http->https redirections, etc.)

It seems that your application's web.xml has a mapping to <code>"/*"</code>. A servlet-mapping to <code>"/*"</code> causes tomcat to pass the request as-is to the web application (i.e. does not redirect).

To properly redirect, you must change the <code>"/*"</code> mapping to just <code>"/"</code>, the latter means the default servlet.

It's an old post, but as of Tomcat 7.0.67, you need to add the following attribute to your context.xml file:

<pre><code>&lt;Context mapperContextRootRedirectEnabled="true"&gt;...&lt;/Context&gt;
</code></pre>

As per the 7.0.67 <a href="https://tomcat.apache.org/tomcat-7.0-doc/changelog.html" rel="noreferrer">changelog</a>:

<blockquote>
 Move the functionality that provides redirects for context roots and directories where a trailing / is added from the Mapper to the DefaultServlet. This enables such requests to be processed by any configured Valves and Filters before the redirect is made. This behaviour is configurable via the mapperContextRootRedirectEnabled and mapperDirectoryRedirectEnabled attributes of the Context which may be used to restore the previous behaviour.
</blockquote>

And in the Tomcat context <a href="https://tomcat.apache.org/tomcat-7.0-doc/config/context.html" rel="noreferrer">documentation</a>:

<blockquote>
 mapperContextRootRedirectEnabled: If enabled, requests for a web application context root will be redirected (adding a trailing slash) if necessary by the Mapper rather than the default Servlet. This is more efficient but has the side effect of confirming that the context path exists. If not specified, the default value of false is used.
</blockquote>

blocks|key|2839117|text|Pat的出色回答帮助我挖掘了更多关于这方面的细节。这似乎与Tomcat的一些版本(+7.0.67%2B上的Tomcat7，以及8.29和8.37之间的Tomcat8)中的一些与会话cookie和URL重定向有关的怪癖有关。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|2839118|底线似乎是，如果java服务器创建的特定于路径的会话cookie末尾带有斜杠(如"/app_name/")，那么服务器还必须执行自动初始重定向(/app_name+-->+/app_name/)+...否则，会话cookie将不会随请求一起发送，并且它永远不会在服务器上显示为您拥有一个有效的会话。这可能会导致从应用程序到身份验证的重定向循环。|2839119|Tomcat中有一些配置可以控制这两种行为，但据我所知，它们在这些版本中基本上是不同步的，因此可能会获得带有尾随斜杠的cookie，而不会获得重定向。Tomcat+changelog中有几个相关的问题/更改：https://tomcat.apache.org/tomcat-8.0-doc/changelog.html|offset|length|2839120|正如Pat已经注意到的，这是通过将以下属性添加到应用程序的上下文元素来解决的：|2839121|<Context+mapperContextRootRedirectEnabled="true">|code-block|syntax|javascript|2839122|entityMap|0|LINK|mutability|MUTABLE|url|https://tomcat.apache.org/tomcat-8.0-doc/changelog.html^0|0|0|2W|1J|0|0|0|0^^$0|@$1|2|3|4|5|6|7|W|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|X|8|@]|9|@]|A|$]]|$1|D|3|E|5|6|7|Y|8|@]|9|@$F|Z|G|10|1|11]]|A|$]]|$1|H|3|I|5|6|7|12|8|@]|9|@]|A|$]]|$1|J|3|K|5|L|7|13|8|@]|9|@]|A|$M|N]]|$1|O|3|-4|5|6|7|14|8|@]|9|@]|A|$]]]|P|$Q|$5|R|S|T|A|$U|V]]]]

Pat's excellent answer helped me dig up a few more details on this. It seems this is related to some quirks in some versions of Tomcat (Tomcat 7 at 7.0.67+, and Tomcat 8 between 8.29 and 8.37) having to do with session cookies and URL redirection. 

The bottom line seems to be that if the java server creates path-specific session cookies with a slash at the end (like "/app_name/"), then the server must also do an automatic initial redirect (/app_name --> /app_name/) ... otherwise, the session cookie will not get sent with the request, and it will never look to the server like you have a valid session. The may cause a redirect loop from the app to the authentication.

There are configurations in Tomcat that control both behaviors, but as far as I can tell, they were essentially out-of-sync in these versions, such that one might get the cookie with the trailing slash, without getting the redirect. There are several related issues/changes in the Tomcat changelog:
<a href="https://tomcat.apache.org/tomcat-8.0-doc/changelog.html" rel="nofollow noreferrer">https://tomcat.apache.org/tomcat-8.0-doc/changelog.html</a>

As Pat has already noted, this is resolved by adding this attribute to your app's Context element: 

<pre><code>&lt;Context mapperContextRootRedirectEnabled="true"&gt;
</code></pre>

I'd like to have Tomcat automatically add a trailing slash to my app's context if the url is entered without it.

When I test with Jetty, it automatically adds the trailing slash to my app's context, but Tomcat doesn't do this.

I'm uncertain what the context will be named once deployed, as I'm handing the WAR off to someone else, so any resource references in HTML is all relative. Is there any way to have Tomcat automatically redirect to the same context with a trailing slash added?

Currently Using Tomcat 7 with Spring 3.

如果没有输入url，我想让Tomcat自动在我的应用程序上下文中添加一个尾随斜杠。当我使用Jetty进行测试时，它会自动将尾部斜杠添加到我的应用程序上下文中，但Tomcat不会这样做。我不确定部署后上下文将被命名为什么，因为我将战争交给了其他人，所以HTML中的任何资源引用都是相对的。有没有办法让Tomcat自动重定向...
