如何从Apache Tomcat中的URL中删除应用程序上下文

Question

I have a war test.war. I deployed it in webapps folder.

Now I can access the web application by URL www.domain.com/test/login

In order to remove the war name, I renamed the war to ROOT.war

So Now I am able to access the web application by URL www.domain.com/login

Can someone please guide me How to access the web application by URL www.domain.com

PS I cannot modify the contents of my WAR file.

Answer 1

Put a HTTP server in front of your application server. That will allow you to create and redirect virtual hosts into specific URLs inside your application server. It's called a reverse proxy.

Eg

www.domain.com -> localhost:8080/mylogin
subdomain.domain.com -> localhost:8080/otherapp/frontpage

If you are using Tomcat 7+, you can use an empty URI pattern in your web.xml to map an empty request to the context root.

<servlet>
    <servlet-name>login</servlet-name>
    <servlet-class>com.example.LoginServlet</servlet-class>
     ...
</servlet>

 ...
<servlet-mapping>
    <servlet-name>login</servlet-name>
    <url-pattern></url-pattern>
</servlet-mapping>

Tomcat 8 has a URL rewrite mechanism.similar to Apache's mod_rewrite.

See http://tomcat.apache.org/tomcat-8.0-doc/rewrite.html
