Question

运行Arquillian测试时出现的奇怪问题。如果我尝试使用带@Stateless注释的EJB，我会收到此错误：

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]

我有Arquillian的以下测试类+部署：

@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：

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

远程接口只有@Remote注释。

如果我将 @Stateless 更改为 @Named ，则可以。但我想使用@Stateless。

为了测试非单例的无状态 EJB 的注入，您需要部署到嵌入式容器。

我遇到了同样的问题，这篇博文为我指明了正确的方向。 https://blog.payara.fish/how-to-test-applications-with-payara-server-micro-with-arquillian

我的工作 pom.xml

<dependencyManagement>
    <dependencies>
        <dependency>

            <type>pom</type>
            <scope>import</scope>
        </dependency>
    </dependencies>
</dependencyManagement>
