@EJB注入與Arquillian WebLogic 10.3.5不起作用

Question

我正在使用Arquillian在WebLogic 10.3.5上運行基本單元測試。不幸的是，@EJB注入對我不起作用，並且在EJB被調用時得到一個NullPointerException。

我發現的例子不需要添加ejb-jar.xml，但我添加了一個。在任何情況下，都會拋出NullPointerException。

任何想法？

單元測試：

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!"); 
    } 
} 

輸出：

我的EJB接口：

package eu.ema.eudract.results; 

import javax.ejb.Remote; 

@Remote 
public interface DummyService { 

    String doNothing(); 
} 

EJB實現：

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!"; 
    } 

} 

個

的arquillian.xml

<?xml version="1.0"?> 
<arquillian xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
    xmlns="http://jboss.org/schema/arquillian" 
    xsi:schemaLocation="http://jboss.org/schema/arquillian http://jboss.org/schema/arquillian/arquillian_1_0.xsd"> 

    <container qualifier="arquillian-wls-remote-10.3" default="true"> 
     <configuration> 
      <property name="adminUrl">t3://localhost:7001</property> 
      <property name="adminUserName">weblogic</property> 
      <property name="adminPassword">aaaaaaaa</property> 
      <property name="wlsHome">C:\dbin\wls1035_dev\wlserver\</property> 
      <property name="target">AdminServer</property> 
     </configuration> 
    </container> 

</arquillian> 

的依賴，我說：

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

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

Answer 1

WLS 10.3.5是一個JEE5兼容的容器，所以你不能有一個EJB駐留在網絡模塊（自JEE6以來支持，即WLS 12c）。

爲了在WLS 10.3.x中將EJB注入到測試類中，您需要在ShrinkWrap WebArchive的web.xml中提供相關聯的ejb-local-ref條目。如果你準備EAR歸檔，那麼你就需要將這些條目添加到會與Servlet的的Arquillian TestRunner的富集的WebArchive。

這方面的一個例子是在的Arquillian GitHub的庫in the WebLogicInjectionTestCase類可用。關聯的web.xml文件是in-container-web-eartest.xml。

注意，當您嘗試本地EJB的注射，因爲WLS不JNDI樹約束他們，默認情況下EJB本地-REF條目絕對必需的。您可能可以跳過遠程EJB的此先決條件。
