JavaEE5学习笔记08-JPA与EJB集成总结(3)

1.       测试代码

部署成功后，在另一个项目中建立测试代码如下

public class TestJPASessionBean extends TestCase {       static Context context;       public Context init() {          if (context == null) {            String init_factory = "org.jnp.interfaces.NamingContextFactory";            String serverURL = "jnp://127.0.0.1:1099";              Properties properties = new Properties();            properties.put(Context.INITIAL_CONTEXT_FACTORY, init_factory);              properties.put(Context.URL_PKG_PREFIXES,                   "org.jboss.naming:org.jnp.interfaces");              properties.put(Context.PROVIDER_URL, serverURL);            try {               context = new InitialContext(properties);            } catch (NamingException e) {               // TODO Auto-generated catch block               e.printStackTrace();            }        }          return context;     }       public void test01save() throws NamingException {          context = init();        IPersonEAO personEAO = (IPersonEAO) context               .lookup("myear/PersonEAO/remote");        Person person = new Person();        person.setName("千叶传奇");        personEAO.save(person);       }       public void test02list() throws NamingException {        context = init();        IPersonEAO personEAO = (IPersonEAO) context               .lookup("myear/PersonEAO/remote");        List<Person> personList = personEAO.findAll();        for (Person person : personList) {            System.out.println("id:" + person.getId() + "-----name:"                   + person.getName());        }     }       public void test03listByCondition() throws NamingException {        context = init();        IPersonEAO personEAO = (IPersonEAO) context               .lookup("myear/PersonEAO/remote");        Person person = personEAO.findByName("素还真").get(0);        System.out.println("id:" + person.getId() + "______name:"               + person.getName());     } }

因为sessionBean是部署到ear包中，所以在JNDI查找的时候一定要用名称” myear/PersonEAO/remote”才能找到服务对象。本程序执行前数据库如下

 

执行测试程序后，控制台如下：

id:1-----name:刘岩 id:2-----name:素还真 id:3-----name:叶小钗 id:4-----name:一页书 id:5-----name:剑藏玄 id:6-----name:傲笑红尘 id:7-----name:花风云 id:8-----name:宇文天 id:9-----name:欧阳上智 id:10-----name:欧阳尚智 id:11-----name:史艳文 id:12-----name:史青青 id:13-----name:一线生 id:14-----name:冷剑白狐 id:15-----name:乱世狂刀 id:16-----name:魔魁 id:17-----name:独眼龙 id:18-----name:金太极 id:24-----name:千叶传奇 id:2______name:素还真

红色是 test02list() 方法的结果，蓝色是 test03listByCondition() 的结果。
