Extending The Spring Framework (Java) Servlet

I'm working on a Java web app that uses the Spring Framework (MVC). All my code is in controller files that are instantiated by the servlet. I would like to extend the servlet so that I can run some code in the init of the servlet; however, I'm very new to the Spring Framework and Java web development in general. I'm not sure how to extend the servlet, where I would put my derived servlet, etc. Can someone point me in the right direction on this?

Solution

  • Did you mean dispatcherServlet? you can just extends this servlet, re-config it in web.xml. 

    <servlet>
<servlet-name>springmvc</servlet-name>
<servlet-class>Your DispatcherServlet</servlet-class>
<init-param>
  <param-name>contextConfigLocation</param-name>
  <param-value>classpath:/META-INF/springmvc-servlet.xml</param-value>
</init-param>
<load-on-startup>1</load-on-startup>
