在WebLogic 10.3.5上使用Arquillian进行@EJB注入不起作用 [英] @EJB injection with Arquillian on WebLogic 10.3.5 doesn't work
本文介绍了在WebLogic 10.3.5上使用Arquillian进行@EJB注入不起作用的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我正在使用Arquillian在WebLogic 10.3.5上运行基本的单元测试。不幸的是，@ EJB注入对我不起作用，并且在调用EJB时得到NullPointerException。
I am using Arquillian to run a basic unit test on WebLogic 10.3.5. Unfortunately, @EJB injection does not work for me, and get a NullPointerException when the EJB is invoked.
我发现的示例不需要ejb-jar.xml。要添加，但我添加了一个。无论如何，都会抛出NullPointerException。
The examples I found don't require an ejb-jar.xml to be added, but I added one. In any case, a NullPointerException is thrown.
有什么想法吗？
单元测试：
import static org.testng.Assert.assertEquals;
import java.io.File;
import javax.ejb.EJB;
import org.jboss.arquillian.container.test.api.Deployment;
import org.jboss.arquillian.testng.Arquillian;
import org.jboss.shrinkwrap.api.ShrinkWrap;
import org.jboss.shrinkwrap.api.exporter.ZipExporter;
import org.jboss.shrinkwrap.api.spec.JavaArchive;
import org.testng.annotations.Test;
import eu.ema.eudract.results.DummyService;
import eu.ema.eudract.results.DummyServiceBean;
public class ResultStatefulServiceBeanIntegrationTest extends Arquillian {
@Deployment
public static JavaArchive createDeployment() {
JavaArchive archive = ShrinkWrap.create(JavaArchive.class, "test.jar")
.addClasses(DummyService.class, DummyServiceBean.class)
.addAsManifestResource("META-INF/ejb-jar.xml", "ejb-jar.xml");
System.out.println(archive.toString(true));
archive.as(ZipExporter.class).exportTo(new File("C:\\Users\\fragkakm\\Desktop\\test.jar"), true);
return archive;
}
@EJB
private DummyService dummyService;
@Test
public void loadResultTest() {
assertEquals(dummyService.doNothing(), "Did nothing!");
}
}
输出：

/eu/ema/eudract/
/eu/ema/eudract/results/

我的EJB接口：
package eu.ema.eudract.results;
import javax.ejb.Remote;
@Remote
public interface DummyService {
String doNothing();
}
EJB实现：
package eu.ema.eudract.results;
import javax.ejb.Stateless;
import eu.ema.eudract.results.DummyService;
@Stateless
public class DummyServiceBean implements DummyService {
public String doNothing() {
return "Did nothing!";
}
}

推荐答案
WLS 10.3.5是符合JEE5的容器，因此您不能在Web模块中驻留EJB（自JEE6即WLS 12c开始受支持）。
WLS 10.3.5 is a JEE5 compliant container, so you cannot have an EJB resident in a web-module (which is supported since JEE6 i.e. WLS 12c).
要允许将EJB注入WLS中的测试类中10.3.x，您需要在ShrinkWrap WebArchive ejb-local-ref 条目。 $ c>。如果准备EAR归档文件，则需要将这些条目添加到 WebArchive 中，该条目将通过Arquillian Servlet Testrunner进行充实。
To allow for EJBs to be injected into your test class in WLS 10.3.x, you'll need to provide the associated ejb-local-ref entries in your web.xml of your ShrinkWrap WebArchive. If you prepare an EAR archive, then you'll need to add these entries into the WebArchive that would be enriched with the Arquillian Servlet Testrunner.
在Arquillian GitHub存储库中有这样的示例类中的/test/java/org/jboss/arquillian/container/wls/remote_10_3/WebLogicInjectionTestCase.java rel = nofollow>。关联的web.xml文件为 in-container-web-eartest.xml 。
An example of this is available in the Arquillian GitHub repository in the WebLogicInjectionTestCase class. The associated web.xml file is in-container-web-eartest.xml.
请注意，ejb-local-ref条目绝对是尝试注入本地EJB时需要使用，因为默认情况下WLS不会将它们绑定在JNDI树中。您也许可以跳过远程EJB的先决条件。
Note that the ejb-local-ref entries are definitely required when you attempt injection of Local EJBs, since WLS does not bind them in the JNDI tree, by default. You might be able to skip this prerequisite for remote EJBs.
