Question

我正在尝试了解Stateful Session bean的生命周期。我在调用激活和钝化生命周期回调时特别感兴趣。我创建了一个演示来理解这个场景。这是我的代码：

我的远程界面是：

package com.orbit.stateful;
import javax.ejb.Remote;
import java.util.List;
@Remote
public interface ShoppingCart 
{
    public void addItem(String itemName);
    public void removeItem(String item);
    public List<String> getAllItems();
    public void finishShopping();
}

我的有状态会话bean类如下：

package com.orbit.stateful;
import javax.ejb.Stateful;
import javax.ejb.Remove;
import javax.ejb.PrePassivate;
import javax.ejb.PostActivate;
import javax.ejb.StatefulTimeout;
import javax.annotation.PostConstruct;
import javax.annotation.PreDestroy;
//import java.util.concurrent.TimeUnit;
import java.util.List;
import java.util.ArrayList;
@Stateful
//@StatefulTimeout(value=5L,unit=TimeUnit.MINUTES)
public class ShoppingCartBean implements ShoppingCart 
{
    private List<String> itemList;
    public ShoppingCartBean(){
        System.out.println("Stateful SessionBean Constructor Called");
    }
    @PostConstruct
    public void intialize(){
        System.out.println("Initializing shopping Cart");
        itemList=new ArrayList<String>();
    }
    public void addItem(String itemName){
        itemList.add(itemName);
    }
    public void removeItem(String item){
        itemList.remove(item);
    }
    public List<String> getAllItems(){
        return itemList;
    }
    @Remove
    public void finishShopping(){
        System.out.println("I am finished with Shopping");
    }
    @PreDestroy
    public void tidyUp(){
        System.out.println("Remove Shopping Bean");
    }
    @PrePassivate
    public void logPassivation(){
        System.out.println("Passivating Now");
    }
    @PostActivate
    public void logActivation(){
        System.out.println("Activating Now");
    }
}

此bean的独立客户端是：

package com.orbit.stateful;
import javax.naming.Context;
import javax.naming.InitialContext;
import java.util.Properties;
import java.util.List;
public class ShoppingCartClient  
{
    public static void main(String[] args) throws Exception
    {

         Properties props = new Properties();
         props.setProperty("java.naming.factory.initial",
                    "com.sun.enterprise.naming.SerialInitContextFactory");
         props.setProperty("java.naming.factory.url.pkgs",
                    "com.sun.enterprise.naming");
         props.setProperty("java.naming.factory.state",
                    "com.sun.corba.ee.impl.presentation.rmi.JNDIStateFactoryImpl");
          props.setProperty("org.omg.CORBA.ORBInitialHost", "localhost");
          props.setProperty("org.omg.CORBA.ORBInitialPort", "3700");
          Context ctx=new InitialContext(props);
          ShoppingCart sc=(ShoppingCart)ctx.lookup("com.orbit.stateful.ShoppingCart");
          sc.addItem("J2SE");
          //Thread.sleep(17000);
          sc.addItem("J2EE");
          sc.addItem("JDBC");
          List<String> books=sc.getAllItems();
          for (String str: books )
          {
              System.out.println("Books is : "+ str);
          }
          //sc.finishShopping();

    }
}

现在我在GlassFish 3.1.2中设置了Cache Idle Timeout = 20 但是我的有状态会话bean在20秒后仍然没有被钝化。我在Glashfish做错了什么或者没有正确发生什么事情？帮助我理解这一点。在此先感谢

高速缓存空闲超时（cache-idle-timeout-in-seconds）过去后，状态会话Bean不会被钝化
