Re: [S2] ModelDriven, Preparable and SessionAware do not work with Spring
Hi All,
I managed to achieve what I wanted by using Struts 2 interceptor without
having Spring aoping the action class through dynamic proxy. Here is the
updated example.xml:
http://struts.apache.org/dtds/struts-2.0.dtd";>
/example/HelloWorld.jsp
/example/Login.jsp
Menu
/example/Menu.jsp
/example/{1}.jsp
An updated TimeLoggingInterceptor.java:
package interceptor;
import org.apache.log4j.Logger;
import com.opensymphony.xwork2.ActionInvocation;
import com.opensymphony.xwork2.interceptor.AbstractInterceptor;
public class TimeLoggingInterceptor extends AbstractInterceptor {
protected final Logger logger = Logger.getLogger(getClass());
public String intercept(ActionInvocation invocation) throws Exception {
long startTime = System.currentTimeMillis();
String result = invocation.invoke();
long endTime = System.currentTimeMillis();
logger.info("MenuAction: Time took = " + (endTime - startTime)
+ " ms");
return result;
}
}
So, I think it is better to go through the framework interceptor (Struts 2)
to aop the action class instead of using Spring interceptor. For other
purpooses, we can use Spring interceptors.

ModelDriven, Preparable and SessionAware do not work with Spring
Hi All, I think I know what is the trouble but am still not sure why is this a problem for Struts 2.0. I hope someone from the Struts community can help to shed some light. Or what is the recommended way of aoping the action class if spring proxy is not the route to go. The problem is when I use " org.springframework.aop.framework.ProxyFactoryBean" to AOP the Action class. Once I remove the AOP piece such as the following, everything work just fine: Any help is greatly appreciated! Thanks, Lee
Re: [S2] ModelDriven, Preparable and SessionAware do not work with Spring
One quick thing I see wrong is you have singleton="false" that is a
spring 1 attribute.

public Object getModel() {

getSession().get("user");
} else {
user = new User();
}
}
public void setSession(Map session) {
_session = session;
}
public Map getSession() {
return _session;
}
}
When I let Spring manages the creation of objects, the methods for the
implemented interfaces such as getModel() and prepare() are not invoked.
If
I change the class="Menu" to class="example.Menu", the interfaces methods
were invoked since I am not letting spring manages object creation.
Could someone let me know what I may have done wrong? How can I use Spring
and Struts at the same time without losing either functionality?
Any help is greatly appreciated.
Thanks!

ModelDriven, Preparable and SessionAware do not work with Spring
Hi All,
I have been playing with Struts 2.0 sample application, struts-blank, and
integrates it with Spring 2.x. So far, I have not been having great success
with it.
I have followed all the steps needed to integrate Struts 2.0 with Spring 2.0.
Here is what I have done so far:
1) Included struts2-spring-plugin-2.0.6.jar, spring.jar,
struts2-core-2.0.6.jar and the dependent jars.
2) Modified the example.xml to include spring object factory:
http://struts.apache.org/dtds/struts-2.0.dtd";>
/example/HelloWorld.jsp
/example/Login.jsp
Menu
/example/Menu.jsp
/example/{1}.jsp
3) I have edited the spring applicationContext.xml
http://www.springframework.org/dtd/spring-beans.dtd";>
execute
example.IMenu
timeLoggingAdvisor
4) Implemented ModelDriven, Preparable and SessionAware interfaces in
Menu.java:
package example;
import java.util.Map;
import org.apache.struts2.interceptor.SessionAware;
import com.opensymphony.xwork2.ModelDriven;
import com.opensymphony.xwork2.Preparable;
/**
* Set welcome message.
*/
public class Menu extends ExampleSupport implements IMenu, ModelDriven,
Preparable, SessionAware {
private Map _session;
private User user;
public String execute() throws Exception {
return SUCCESS;
}
public Object getModel() {
return user;
}
public void prepare() throws Exception {
if (getSession().get("user") != null) {
user = (User) getSession().get("user");
} else {
user = new User();
}
}
public void setSession(Map session) {
_session = session;
}
public Map getSession() {
return _session;
}
}
When I let Spring manages the creation of objects, the methods for the
implemented interfaces such as getModel() and prepare() are not invoked. If
I change the class="Menu" to class="example.Menu", the interfaces methods
were invoked since I am not letting spring manages object creation.

and Struts at the same time without losing either functionality?
Any help is greatly appreciated.
