在Arquillian测试中注入@Stateless EJB [英] Injecting @Stateless EJB in Arquillian tests

问题描述

运行Arquillian测试时出现一个奇怪的问题.如果我尝试使用带有@Stateless注释的EJB，则会出现此错误:

A weird problem when running Arquillian test. If I try to use an EJB annotated with @Stateless, I get this error:

org.jboss.weld.exceptions.DeploymentException: WELD-001408 Unsatisfied dependencies for type [MyEjbRemote] with qualifiers [@Default] at injection point [[field] @Inject private com.org.app.ejb.InjectionTest.ejb]

对于Arquillian，我具有以下测试类和部署:

I have the following test class + deployment for the Arquillian:

@RunWith(Arquillian.class)
public class InjectionTest extends TestCase {

  @Inject
  private MyEjbRemote ejb;

  @Deployment
  public static JavaArchive createDeployment() {
    JavaArchive jar = ShrinkWrap.create(JavaArchive.class, "test.jar").addAsManifestResource(EmptyAsset.INSTANCE, "beans.xml"));
    jar.addClass(MyEjbRemote.class);
    jar.addClass(MyEjb.class);
  }

  @Test
  public void checkInjection() {
    TestCase.assertNotNull(ejb);
  }
}

EJB看起来像这样:

The EJB looks like this:

@Stateless
@Default
public class MyEjb implements MyEjbRemote {
  public MyEjb() {
  }
}

远程接口仅具有@Remote注释.

The remote interface just has @Remote annotation.

如果我将 @Stateless 更改为 @Named ，则可以使用.但是我想使用@Stateless.

If I change the @Stateless to @Named, it works. But I wan to use the @Stateless.

推荐答案

为了测试不是Singletons的无状态EJB的注入，您需要部署到嵌入式容器.

In order to test injection of Stateless EJBs that are not Singletons you need to deploy to an embedded container.
