会话Bean相关

EJB-03:

 

package com.zh.ejb;

 

import javax.ejb.Local;

import javax.ejb.Remote;

import javax.ejb.Stateless;

 

 

 

@Stateless

@Remote

@Local

public class UserManagerBean implements UserManager{

 

    @Override

    public void addUser(User user) {

       System.out.println("User[username="+user.getUsername() +"]has been saved");

       user.setId(10);

    }

 

}

 

远程客户端在EJB端改变对象值客户端不可见

本地客户端在EJB端改变对象值客户端可见

 

 

所传输的对象要实现序列化接口(本地web客户端可以不实现序列化接口)

 

使用本地WEB客户端时出现ClasscastException

 

$JBOSS_HONE/server/default/deploy/jboss-web.deployer/META-INF/jboss-service.xml

 

<attribute name="UseJBossWebLoader">true</attribute>

 

 

EJB-04

package com.zh.ejb;

 

import javax.ejb.Local;

import javax.ejb.Remote;

import javax.ejb.Stateless;

 

 

@Stateless(name="ejb04beanname")

@Remote({Ejb04Interface01.class,Ejb04Interface02.class})

@Local({Ejb04Interface03.class,Ejb04Interface04.class})

public class Ejb04Bean implements Ejb04Interface01,Ejb04Interface02 ,Ejb04Interface03 ,Ejb04Interface04{

 

    @Override

    public void m1() {

       System.out.println("method m1 has been invoked");

    }

 

   

    @Override

    public void m2() {

       System.out.println("method m2 has been invoked");

    }

   

 

    @Override

    public void m3() {

       System.out.println("method m3 has been invoked");

    }

 

    @Override

    public void m4() {

       System.out.println("method m4 has been invoked");

    }

 

}

 

 

 

远程客户端只可以访问@Remote后面的接口

本地客户端@Remote,@Local都可以

 

 

也可以将@Remote,@Local直接定义在相应的接口上
