Tomcat - 将项目文件夹设置为Web根目录

Question

I have this folder under Tomcat webapps/mysite which is where all my JSPs and other things are located. To access this folder I go to http://blah.com/mysite and it works just fine. However (because of stylesheets and images statically connected to the root / ) I have to make it so that when I go to http://blah.com/ it will load the stuff inside webapps/mysite .

I've tried many different things including contexts and setting the absolute path in server.xml ... nothing seems to work, whenever I go to http://blah.com/ it still tries to load the ROOT folder... what's happening here?

Answer 1

The solution I use is to set this in your Tomcat server.xml

Add a <Context> element within the <Host> like below which sets your mysite as the default web app. Note the empty path="" which makes it the default.

<Context docBase="mysite" path="" /> 

Attributes of Context Container from the Tomcat docs:

docBase You may specify an absolute pathname for this directory or WAR file, or a pathname that is relative to the appBase directory of the owning Host.

path All of the context paths within a particular Host must be unique. If you specify a context path of an empty string (""), you are defining the default web application for this Host, which will process all requests not assigned to other Contexts.

Answer 2

There are a number of ways to make an application the root application. The simplest way is to just replace the contents of webapps/ROOT with the contents of your web application.

Answer 3

https://stackoverflow.com/users/1123501/george-siggouroglou 's awnser works but lacks a step.

• delete ROOT and all items
• copy the war to webapps as ROOT.war

Without the deletion, it may not work. Tested with docker.

Answer 4

You can rename your war from something.war == to ==> ROOT.war .
So, tomcat will unpack the war and will create the folder ROOT for it.
It is a trick that is working on tomcat 8 also.
