Struts 2/Spring and @Required
Hello All,
One of the nice annotation features of spring is the ability to annotate injected fields with @Required so that you don't get null pointer exceptions. However, I can only seem to get this to work
with my test cases (spring throws an error when a required field isn't set), but I can't get the same behavior on the startup of my struts 2 web app. Does anyone know if it's possible for the web-app
to break when an @Required field isn't set at startup?
Thanks,
Tim

Don't forget that you need to instantiate a bean postprocessor in your
applicationContext to enforce the @Required-annotation:
<bean
class="org.springframework.beans.factory.annotation.RequiredAnnotationBeanPostProcessor"
/>

I don't supply any configuration to spring. I simply have the applicationContexts constructing beans, and then have a couple of lines in my struts.xml configuring the Object Factory and the autowire
method.
<constant name="struts.objectFactory" value="org.apache.struts2.spring.StrutsSpringObjectFactory" />
<constant name="struts.objectFactory.spring.autoWire" value="type" />
and of course have the listeners set up in my web-xml. What sort of configuration would be needed to get this to work?
Thanks,
Tim

You should post your spring xml config file, it looks like some AOP
config is probably missing.

//the struts-convention-plugin allows you to supply your own params e.g.
public class HelloWorld extends ActionSupport {
@Action(value="/different/url",
results={@Result(name="success", type="httpheader", params={"status", "500", "errorMessage", "Internal Error"})}
http://cwiki.apache.org/WW/convention-plugin.html
does this help?
