在 Arquillian 测试中注入 class 始终为 null

Question

我在我的 Eclipse IDE 安装 JBoss Tools 插件并将项目创建为 New > JBoss Central > Java EE EAR Project。我使用了 Wildfly 8.2.0.Final 服务器。我的项目模板的 EJB 模块如下

Arquillian 对我的项目的依赖是通过项目模板创建的，我没有修改任何东西。然后我创建了我的第一个测试 class 作为

@RunWith(Arquillian.class)
public class CustomerServiceTest {
    @Inject
    private CustomerDao customerDao;

    @Deployment
    public static Archive<?> createDeployment() {

    JavaArchive archive = ShrinkWrap.create(JavaArchive.class, "test.jar")
        .addAsResource("META-INF/test-persistence.xml","META-INF/persistence.xml")
        .addAsManifestResource(EmptyAsset.INSTANCE, "beans.xml");
    archive.addClass(CustomerDto.class);
    archive.addClass(Customer.class);
    archive.addClass(CustomerDao.class);
    archive.addClass(Dao.class);

    System.out.println(archive.toString(true));
    return archive;
    }

    @Test
    public void getCustomers() {
    // customerDao Always Null
    System.out.println("############# Testing Success ##################"+ customerDao);
    }
}

这是控制台日志

我完全是 Arquillian 测试的新手。我找到并研究了许多 Arquillian 测试示例。这些看起来不错，但我的有什么问题吗？感谢您阅读我的问题。乐于帮助新手。

Answer 1

错误消息表明 JBoss 无法创建 CustomerDao 的实例。最可能的原因是缺少一个或多个依赖项。

也许您需要添加：

archive.addClass(CustomerDaoImpl.class);

在 Arquillian 测试中注入 class 始终为 null

Injecting in Arquillian test class always null

java

jboss

jboss-arquillian
