如何从tomcat服务器中已部署的WAR文件中获取完整的URL

Question

I wanted to get the full URL of my war app when I deploy it on the server. Let say my application war file is "test.war" and my tomcat installation is on " http://localhost:8080/ ".

What I want is to get the " http://localhost:8080/test/ " value from my Java code inside of this war file, since I have to pass them around to other services.

I am using maven to build the war file, so any maven-specific solution is also welcome.

Answer 1

URL: " http://localhost:8080/ "

URL: " http://localhost:8080/test/ "

Uri: "/test/" in java code

String uri = request.getContextPath();

Request is class HttpServletRequest
When deploy server tomcat if file .war with name is ROOT.war --> URL is http://localhost:8080/
With file --> URL is http://localhost:8080/abc/ ---> abc is context path
