这是我第一次使用 OpenEJB 容器系统。当我使用 InitialContext 的锁定方法时,我得到一个 NameNotFoundException。我已经阅读了很多示例和教程,在每个示例中,查找方法如下所示:

initialContext.lookup("NameOfBean");

现在我找到了另一种解决方案,它使用类似以下代码片段的查找,它也适用于我。

initialContext.lookup("java:global/classpath.ear/ProjectName/NameofBean");

问题是为什么第一个版本对我不起作用以及我做错了什么?

这是我的测试类:

public class NamerOfBeanOpenEJBTest {

private static InitialContext initialContext;

@BeforeClass
public static void setUp() throws Exception {
       Properties properties = new Properties();
       properties.setProperty(Context.INITIAL_CONTEXT_FACTORY, "org.apache.openejb.client.LocalInitialContextFactory");
       properties.setProperty("openejb.deployments.classpath.include", ".*");
               initialContext = new InitialContext(properties);
}
@Test
public void testBean() throws NamingException{  
    Object object = initialContext.lookup("java:global/classpath.ear/ProjectName/NameOfBean");
    assertNotNull(object);
    assertTrue(object instanceof NameOfBean);
}

@AfterClass
public static void afterClass() throws Exception {
    if (initialContext != null) {
        initialContext.close();
    }}
}

有人对我有提示或解决方案吗?非常感谢。

编辑:

在 JBoss AS 7.1 中,查找可以像这个例子一样放置:

new InitialContext().lookup("ejb:/ProjectName//NameOfBean!de." + "mypath.sessionbean.stateless.NameOfBeanInterface");

这在 OpenEJB 中不可能吗?我是否必须更改每个 bean 中的每个查找调用才能使用 OpenEJB 进行本地测试?这不会真正有效和节省时间。

问题解决了!

查找的结构是 {deploymentId}{interfaceType.annotationName}。因此,就我而言,它必须是

initialContext.lookup("NameOfBeanLocal");

或 initialContext.lookup("NameOfBeanRemote"); 取决于接口的类型。

要解决 JBoss 的问题,您可以从默认查找切换

new InitialContext().lookup("ejb:/ProjectName//NameOfBean!de." + "mypath.sessionbean.stateless.NameOfBeanInterface");

到更灵活的东西,如 Dependcy-Lookup 或 Dependency-Injection 并使用 @EJB 注释。JBoss 和 OpenEJB 都支持这两种方式。
