UnknownHandler

[kal stevens]

I have been trying to implement an UnknownHandler, and I can not seem to
find any documentation on how to integrate it into the framework.

I am using spring for DependencyInjection, so I thought that I could just
add a bean named unknownHandler, but that did not work.

I could not find an example of how to set the unknownHandler field in
DefaultActionProxy.

Looking at the source code it looks like I have to apply the
StrutsSpringObjectFactory injector to the DefaultActionProxy but I am not
sure why that us happening.

The map Class -> injectors contains an injector for Spring but it has no
classes.


I am not exactly sure where to look on how to do this.

Thanks

Hi Kal,

The UnknownHandler needs to be defined in struts.xml or
struts-plugin.xml as a bean.
See the struts-plugin.xml file included in the CodeBehind plugin for an
example.

Declaring the bean in struts.xml registers the implementation with the
Struts 2 Container (an XWork Container). It is then injected into other
beans created by the framework when needed.

You may have noticed in the DefaultActionProxy that the UnknownHandler's
setter carries the @Inject annotation and an required=false flag. The
framework wires this setter to the UnknownHandler implementation you
register with the container.
