lifebean.java

这个是学习EJB的好例子,里面有许多关于EJB Bean的

package com.cws.ejb.life;

import javax.annotation.PostConstruct;
import javax.annotation.PreDestroy;
import javax.ejb.Init;
import javax.ejb.PostActivate;
import javax.ejb.PrePassivate;
import javax.ejb.Remote;
import javax.ejb.Remove;
import javax.ejb.Stateful;

@Stateful
@Remote ({Life.class})
public class LifeBean implements Life {

	/* (non-Javadoc)
	 * @see com.cws.ejb.life.remote.Life#say()
	 */
	public String say() {
		try {
			Thread.sleep(1000 * 10);
		} catch (InterruptedException e) {
			e.printStackTrace();
		}
		return "这是会话Bean生命周期应用例子";
	}

	@Init
	public void initialize() {
		System.out.println("initialize()方法被调用");
	}

	@PostConstruct
	public void Construct() {
		System.out.println("Construct()方法被调用");
	}

	@PreDestroy
	public void exit() {
		System.out.println("exit()方法被调用");
	}

	@PrePassivate
	public void serialize() {
		System.out.println("serialize()方法被调用");
	}

	@PostActivate
	public void activate() {
		System.out.println("activate()方法被调用");
	}

	@Remove
	public void stopSession() {
		System.out.println("stopSession()方法被调用");
		// 调用该方法以通知容器移除该bean实例、终止会话。方法体可以是空的。
	}
