How to write apache RewriteRule

Question

Tomcat has a project topic, which is accessed by default at localhost:8080/topic and is now bound to the domain name topic.luger.me. The config file of apache is written like this

<VirtualHost 127.0.0.1> DirectoryIndex /topic/index.jsp ServerName topic.luger.me Options FollowSymLinks rewriteengine on </VirtualHost>
When accessing, you can still access topic.luger.me/topic. How to write RewriteRule rules so that they can be accessed when
topic.luger.me
I have always been wrong when writing this ^(.*) /topic/$1
I can't access it all the time. What's wrong?

Answer 1

You can directly DocumentRoot 指定到topic 路径下，DirectoryIndex /topic/index.jsp

<VirtualHost *:8080>
     ServerName topic.luger.me
     DocumentRoot "/var/www/topic"
     SetEnv APPLICATION_ENV "development"
     <Directory "/var/www/topic">
         DirectoryIndex index.jsp
         AllowOverride All
         Order deny,allow
         Allow from all
     </Directory>
</VirtualHost>

Answer 2

DocumentRoot can’t point directly to the topic? Equivalent to creating a new vhost

Answer 3

Do you want to access topic.luger.me and map it to localhost:8080/topic?
