对于一些小型 JBoss 企业应用程序的测试，我想使用 JUnit，并且Maven 货物插件 http://cargo.codehaus.org/Maven2+plugin。 （我知道还有 JSFUnit，但首先我想仔细看看 Cargo。）
网上是否有一个简单的示例，我可以将其用作运行 JUnit 测试的参考，该测试使用 Maven Cargo 插件使用 JBoss（4.2 或 5.1）调用 EJB 操作？我找到了一些很好的配置介绍，但我在 EJB 查找中收到错误消息，因此了解如何使用它会很有帮助。
这是使用InitialContext的测试代码：
public void testEcho() {
assertEquals("Echo Echo", lookupEchoBeanRemote().Echo("Echo"));
}
private EchoBeanRemote lookupEchoBeanRemote() {
try {
Context c = new InitialContext();
return (EchoBeanRemote) c.lookup("EchoBean/remote");
} catch (NamingException ne) {
Logger.getLogger(getClass().getName()).log(Level.SEVERE, "exception caught", ne);
throw new RuntimeException(ne);
}
}
这给出了这个错误：
testEcho(de.betabeans.Echo2Test) Time elapsed: 0.885 sec <<< ERROR!

如果我使用EJB注释
@EJB(beanInterface=EchoBeanRemote.class,mappedName="EchoBean/remote")
private EchoBeanRemote newSessionBean;
public Echo3Test(String testName) {
super(testName);
}
public void testEcho() {
assertEquals("Echo Echo", newSessionBean.Echo("Echo"));
}
测试结果是
testEcho(de.betabeans.Echo3Test) Time elapsed: 0.001 sec <<< ERROR!
java.lang.NullPointerException
at de.betabeans.Echo3Test.testEcho(Echo3Test.java:20)
jndi.properties 位于 EJB jar 根文件夹中，包含以下行：
java.naming.factory.initial=org.jnp.interfaces.NamingContextFactory
java.naming.factory.url.pkgs=org.jboss.naming:org.jnp.interfaces
java.naming.provider.url=jnp://localhost:1099
### The TimedSocketFactory connection timeout in milliseconds (0 == blocking)
jnp.timeout=0
### The TimedSocketFactory read timeout in milliseconds (0 == blocking)
jnp.sotimeout=0
豆源代码是
package de.betabeans;
import javax.ejb.Remote;
@Remote
public interface EchoBeanRemote {
String Echo(final String in);
}
package de.betabeans;
import javax.ejb.Stateless;
@Stateless
public class EchoBean implements EchoBeanRemote {
public String Echo(final String in) {
return in + " " + in;
}
}
我还测试了一个 Web 应用程序，它可以毫无问题地调用 EJB - 使用 InitialContext 或注释两种方式。我在部署 Web 应用程序时收到的警告是
警告 [MappedReferenceMetaDataResolverDeployer] JBossWebMetaData 中存在未解析的引用：[#web-app:AnnotatedEJBReferenceMetaData{name=de.betabeans.Echo3Servlet/echoBean,ejb-ref-type=null,link=null,ignore-dependecy=false,mapped/jndi- name=EchoBean/remote,resolved-jndi-name=null,beanInterface=interface de.betabeans.EchoBeanRemote}, #web-app:AnnotatedEJBReferenceMetaData{name=NewServlet/newSessionBean,ejb-ref-type=null,link=null,ignore -dependecy=false,mapped/jndi-name=NewSessionBean/remote,resolved-jndi-name=null,beanInterface=interface de.betabeans.NewSessionBeanRemote}]
12:26:11,770 信息
所有测试均使用 JBoss 5.1.0.GA 在两个不同的构建系统上执行。
