在WebLogic 10.3.5上使用Arquillian注入@EJB不起作用

我正在使用Arquillian在WebLogic 10.3.5上运行基本单元测试。不幸的是，@ EJB注入对我不起作用，并在调用EJB时​​得到NullPointerException。

我发现的示例不需要添加ejb-jar.xml，但我添加了一个。无论如何，都会抛出NullPointerException。

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：

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!";
    }

}

arquillian.xml 

<?xml version="1.0"?>
<arquillian xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xmlns="http://jboss.org/schema/arquillian"

            <property name="target">AdminServer</property>
        </configuration>
    </container>

</arquillian>

我添加的依赖项：

<dependency>
    <groupId>org.jboss.arquillian</groupId>
    <artifactId>arquillian-bom</artifactId>
    <version>1.0.1.Final</version>
    <scope>import</scope>

    <scope>test</scope>
    <version>1.0.0.Alpha2</version>
</dependency>

答案 0 :(得分：2)

WLS 10.3.5是符合JEE5标准的容器，因此您不能将EJB驻留在Web模块中（自JEE6起支持，即WLS 12c）。

为了允许在WLS 10.3.x中将EJB注入到测试类中，您需要在ShrinkWrap ejb-local-ref的web.xml中提供关联的WebArchive条目。如果您准备了EAR存档，那么您需要将这些条目添加到WebArchive中，这些条目将使用Arquillian Servlet Testrunner进行丰富。

Arquillian GitHub存储库in the WebLogicInjectionTestCase类中提供了一个示例。关联的web.xml文件为in-container-web-eartest.xml。

请注意，当您尝试注入本地EJB时，肯定需要ejb-local-ref条目，因为默认情况下WLS不会在JNDI树中绑定它们。您可以跳过远程EJB的这个先决条件。
