ServletContextAware interface ignored for custom ActionMapper
-------------------------------------------------------------
Key: WW-3221
URL: https://issues.apache.org/struts/browse/WW-3221
Project: Struts 2
Issue Type: Improvement
Affects Versions: 2.1.6
Environment: Windows XP, Jetty (under Google App Engine java dev
environment).
Reporter: Todd Owen
Priority: Minor
I am implementing an ActionMapper by extending DefaultActionMapper. I would
like to access the ServletContext, where some application-specific
configuration is stored. Since the docs for the ServletContextAware interface
say that it is: "for components that have a dependence on the Servlet context",
I implemented this interface but it's method (setServletContext) is never
called. Here is the class:
public class RexMapper
extends org.apache.struts2.dispatcher.mapper.DefaultActionMapper
implements ServletContextAware {
public RexMapper() {
// This constructor *is* called.
}
@Override
public void setServletContext(ServletContext arg0) {
// This method is *not* called.
}
}
In struts.xml:
<bean type="org.apache.struts2.dispatcher.mapper.ActionMapper"
name="rexMapper" class="org.technologyforchange.rex.RexMapper"/>
I have been able to work around this by using the internal dependency injection
framework: I add a javax.servlet.ServletContext parameter to the constructor,
and annotate it with @com.opensymphony.xwork2.inject.Inject. However, I
understand that developers are encouraged not to rely on the internal injection
framework. Therefore, I'm reporting this to JIRA.
