Question

I am Using Spring MVC project in Tomcat Server.Each time I run the application the server context root is changed. How to set fixed context root?

My projectname is: DemoApplication, first this context root is deployed the path is, http://localhost:8080/DemoApplication

second time it is, http://localhost:8080/Controller Web.xml:

<context-param>
    <param-name>contextConfigLocation</param-name>
    <param-value>/WEB-INF/spring/root-context.xml</param-value>
</context-param>
    <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
<servlet>
    <servlet-name>appServlet</servlet-name>
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
    <init-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>/WEB-INF/spring/appServlet/servlet-context.xml</param-value>
    </init-param>
    <load-on-startup>1</load-on-startup>
</servlet>

<servlet-mapping>
    <servlet-name>appServlet</servlet-name>
    <url-pattern>/</url-pattern>
</servlet-mapping>

servlet-context.xml:

Answer 1

My projectname is: DemoApplication, first this context root is deployed the path is, http://localhost:8080/DemoApplication and second time it is, http://localhost:8080/Controller ?

You NEED TO fix the root context for your web application (DemoApplication) to fix the URL, which you can achieve with one of the below options:

(1) Set the root context as DemoApplication in Tomcat as explained here

(2) If you are using Maven, you can fix your war name by adding the below tag into the pom.xml:

<build>
    <finalName>DemoApplication</finalName>
</build>

Once you are done with either of the above options, you should be able to access your application controller always with below url :

http://localhost:8080/DemoApplication/Controller
