Java EE 远程客户的访问EJB实现实例(Jboss wildfly)

篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了Java EE 远程客户的访问EJB实现实例(Jboss wildfly)相关的知识，希望对你有一定的参考价值。

实例与上一篇GlassFish一致，应用服务器换成wildfiy主要介绍差异部分。

1.准备工作，下载wildfly 10.0.0.final 

2.创建管理员和用户， 解压缩wildfly-10.0.0.Final，在解压后的文件夹中wildfly-10.0.0.Final\\bin 下运行add-user，参考文档进行操作

3.NetBeans服务器中添加服务器->WildFly 应用服务器->选择解压文件夹->使用默认端口和ip

4.修改CCEnterpriseApplication项目属性->运行->服务器选择WildFly 应用服务器，修改CCEnterpriseApplication-ejb，CCEnterpriseApplication-war 服务器改成WildFly 应用服务器

5.修改CCClient库，去除gf-client.jar ，添加 jboss-client.jar (wildfly-10.0.0.Final\\bin\\client 文件夹下)

6.修改客户端连接代码，需要用第4种连接方式，前面三种都不行，Context的参数也发生变化，根据wildfly文档进行修改，用户名密码是步骤2时建立的，Application User 就可以了。

  

 
try {           
           Date d = new Date();  
          Hashtable env = new Hashtable();  
          //GlassFish  
       //  env.put("org.omg.CORBA.ORBInitialHost", "localhost");  
       //  env.put("org.omg.CORBA.ORBInitialPort", "3700");    
         //Jboss   
         env.put(Context.URL_PKG_PREFIXES, "org.jboss.ejb.client.naming");  
         env.put(Context.INITIAL_CONTEXT_FACTORY,"org.jboss.naming.remote.client.InitialContextFactory");  
         env.put(Context.PROVIDER_URL, "http-remoting://localhost:8080");  
         env.put(Context.SECURITY_PRINCIPAL,"user");//用户名  
         env.put(Context.SECURITY_CREDENTIALS, "user");//密码  
         env.put("jboss.naming.client.ejb.context", true);  
         Context  context = new InitialContext(env);             
         Logger.getLogger(LoginJFrame.class.getName()).log(Level.WARNING,String.valueOf(new Date().getTime()-d.getTime()));  
          /** 
           * 1."cc.test.ejb.CCSessionBeanRemote" 
           * 2.CCSessionBeanRemote.class.getName() 
           * 3.java:global/CCEnterpriseApplication/CCSessionBean 
           * 4.CCEnterpriseApplication/CCEnterpriseApplication-ejb/CCSessionBean!cc.test.ejb.CCSessionBeanRemote" 
           *  
           */  
          CCSessionBeanRemote ccSession = (CCSessionBeanRemote)context.lookup("CCEnterpriseApplication/CCEnterpriseApplication-ejb/CCSessionBean!"+CCSessionBeanRemote.class.getName());  
          Logger.getLogger(LoginJFrame.class.getName()).log(Level.WARNING,String.valueOf(new Date().getTime()-d.getTime()));  
          this.messageLabel.setText(ccSession.checkConn());  
          Logger.getLogger(LoginJFrame.class.getName()).log(Level.WARNING,String.valueOf(new Date().getTime()-d.getTime()));  
          CCSessionBeanRemote ccSession2 = (CCSessionBeanRemote)context.lookup("CCEnterpriseApplication/CCEnterpriseApplication-ejb/CCSessionBean!"+CCSessionBeanRemote.class.getName());  
          Logger.getLogger(LoginJFrame.class.getName()).log(Level.WARNING,String.valueOf(new Date().getTime()-d.getTime()));  
      } catch (NamingException ex) {  
          Logger.getLogger(LoginJFrame.class.getName()).log(Level.SEVERE, null, ex);  
      }

 

7.在NetBeans 中启动WildFly服务器，部署CCEnterpriseApplication 项目，运行CCClient，点击连接按钮，查看输出结果，与GlassFish对比可以发现获取Context和EJB都很快不到1s就可以完成，Context.lookup时Jboss的提示信息显示Remoteing connection信息已经变了。这个以后看看会不会有其他影响。

总结一下，从WildFly和GlassFish EJB的远端方法调用可以发现，跟官方文件差别还是有的，从EJB lookup 的路径可以发现，GlassFish 是一个remote对应一个EJB，WildFly是一个项目下面一个remote可以对应多个EJB。一个remote有多个实现是很正常，但是远端方法调用我也不需要知道到底是哪个来实现的，对写代码都没影响。还有一处client端的jar包问题，WildFly比较简单，一个单独的jar文件就可以了，GlassFish 侧重在Server Container 的概念，在与服务器同一台机子会比较简单，一但到实际分发的时候就比较麻烦，因为引入的jar包里面都是关联到其他jar包的。实际jar是空的，可以查看官方文档关于发布的介绍，使用方式是package-appclient ，以后再详细说明。
