spring AOP遇到的问题

Question

在ssh框架中，我想通过aop在用户进行某些操作时验证登陆。但是发现 在aop的动态代理中被代理对象（此例中为ReadJournalAction）的所以属性都为null.
即 还没有经过ognl为ReadJournalAction中的属性赋值就进入了aop代理。
请问这是什么原因？大家又是怎么做的呢？
package second.actions.journal;

import org.apache.struts2.convention.annotation.Action;
import org.apache.struts2.convention.annotation.Result;
import org.springframework.context.annotation.Scope;

import second.dao.madol.Journal;
@Action(value="readjournal",results={@Result(name="success",type="freemarker",location="/Pages/journal.ftl")})
@Scope("prototype")
public class ReadJournalAction extends JournalAction{
private int journalID;

private  Journal journal;




@Override
public String execute() throws Exception {

    journal=journalDAO.findJournal(journalID);



    return SUCCESS;
}



public Journal getJournal() {
    return journal;
}



public int getJournalID() {
    return journalID;
}

public void setJournalID(int journalID) {
    System.out.println("CCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCC");
    this.journalID = journalID;
}

public void setJournal(Journal journal) {
    this.journal = journal;
}

}
package second.actions.aop;

import org.aspectj.lang.annotation.After;
import org.aspectj.lang.annotation.Aspect;
import org.aspectj.lang.annotation.Before;
import org.aspectj.lang.annotation.Pointcut;
import org.springframework.stereotype.Component;

@Aspect
@Component
public class AopTest {

//@Pointcut("execution(* second.actions.journal.ReadJournalAction.execute(..))") 


@Before("execution(* second.actions.journal.ReadJournalAction.*(..))")
public void dobefore(){

    System.out.println("before  login~~~~");
    return;

}
@After("execution(* second.actions.journal.ReadJournalAction.*(..))")
public void doafter(){

    System.out.println("after  login~~~~~~~~~");
    return;

}

}

aop切入的方法，不应该是所有方法，只需要execute方法
