Spring MVC; avoiding file extension in url?

Question

I just started with Spring Web MVC. I'm trying to avoid file extenstions in the url. How can i do this? (I'm using Spring 2.5.x)

Bean:

<bean name="/hello.htm" class="springapp.web.HelloController"/>

I want it to be:

<bean name="/hello" class="springapp.web.HelloController"/>

I cannot get it to work. Any ideas?

Edit:

Url-mapping

<servlet-mapping>
 <servlet-name>springapp</servlet-name>
 <url-pattern>*.htm</url-pattern>
</servlet-mapping>

I have tried changing the url-pattern with no luck (* and /*).

Answer 1

Have you tried <url-pattern>/*</url-pattern> in the servlet mapping and <bean name="/hello" .../> ?

Answer 2

<servlet>
 <servlet-name>spring-mvc</servlet-name>
 <servlet-class>
  org.springframework.web.servlet.DispatcherServlet
 </servlet-class>
 <load-on-startup>1</load-on-startup>
</servlet>

<servlet-mapping>
 <servlet-name>spring-mvc</servlet-name>
 <url-pattern>/*</url-pattern>
</servlet-mapping>

Then you need to register your urls to be handled by a particular controller. See the following

Answer 3

Try first:

<servlet-mapping>
        <servlet-name>spring-mvc</servlet-name>
        <url-pattern>/hello</url-pattern>
</servlet-mapping>

If that doesn't work then problem is somewhere else. Is your Apache set up to forward those urls to Tomcat? Something like:

JkMount /hello worker1

Answer 4

As far as I know you can't do this if you're using JSP's as your view for controllers.

Because when you pass a model to a JSP, Spring MVC internally performs a 'forward' to the URL of the JSP. If you use <url-pattern>/*</url-pattern> then this forward will also be handled by your DispatcherServlet and not by your JSP view.

What you can do is use <url-pattern>/something</url-pattern> and have your JSP's in a different directory

Answer 5

In 3.0, / seems to work. That is...

<url-pattern>/</url-pattern>
