Undertow和Tomcat的Spring Boot .war上下文路径

Question

I have a Spring Boot application which I will deploy as a .war file in existing Tomcat and Undertow(Wildfly) containers. How can I configure the context path from within the application?

I know I can use the .war name directly, but I dont want to do that since the .war name contains version information etc.

Answer 1

From Tomcat configuration docs Defining a context:

Individual Context elements may be explicitly defined:

• In an individual file at /META-INF/context.xml inside the application files. Optionally (based on the Host's copyXML attribute) this may be copied to $CATALINA_BASE/conf/[enginename]/[hostname]/ and renamed to
  application's base file name plus a ".xml" extension.
• ...

Also note:

If you want to deploy a WAR file or a directory using a context path that is not related to the base file name then one of the following options must be used to prevent double-deployment:

• Disable autoDeploy and deployOnStartup and define all Contexts in server.xml
• Locate the WAR and/or directory outside of the Host's appBase and use a context.xml file with a docBase attribute to define it.

Also this is along the lines of what you are looking for How to set the context path of a web application in Tomcat 7.0

For undertow, if it's used as a web server in the wildfly AS try it with a jboss-web.xml like: https://stackoverflow.com/a/28475123/4807777

Answer 2

You can do this in the by adding a /WEB-INF/jboss-web.xml file in the application that you deploy:

<?xml version="1.0" encoding="UTF-8"?> <jboss-web xmlns="http://www.jboss.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation=" http://www.jboss.com/xml/ns/javaee http://www.jboss.org/j2ee/schema/jboss-web_5_1.xsd"> <context-root>/</context-root> </jboss-web>
