Question

我们正在将JavaEE应用程序从Weblogic 10.3.6迁移到Weblogic 12.2.1.2。作为此迁移的一部分，我们正在更改我们的JSF管理bean以使用CDI注释而不是标准的JSF注释。 @ManagedBean到@Named和javax.faces.bean.ViewScoped到javax.faces.view.ViewScoped。事实证明这只是一个小问题。但是我试图让我们的测试运行有一个大问题。测试失败，出现以下错误：

WebBeans context with scope type annotation @ViewScoped does not exist within current thread

我尝试了多个不同的容器（嵌入式和远程）但仍然遇到同样的错误。任何帮助将不胜感激。

我正在使用具有以下pom.xml依赖关系的Arquillian：

BackingBean：

import javax.faces.view.ViewScoped;
import javax.inject.Named;
import java.io.Serializable;

@Named
@ViewScoped
public class AnotherBean implements Serializable {

    public String doTest()
    {
        System.out.println("test");
        return "test";
    }
}

testBean这个

@RunWith(Arquillian.class)
public class TestAgain  {

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

    @Inject
    AnotherBean anotherBean;

    @Test
    public void doTest()
    {
        Assert.assertEquals(anotherBean.doTest(), "test");
        anotherBean.doTest();
    }
}

更新

如果我将@Deployment更改为：

@Deployment
    public static WebArchive createDeployment() {
        return ShrinkWrap.create(WebArchive.class, "test.jar")
                .addClass(AnotherBean.class)
                .addAsManifestResource(EmptyAsset.INSTANCE, "beans.xml");
    }

我得到：

javax.enterprise.inject.UnsatisfiedResolutionException: Api type [AnotherBean] is not found with the qualifiers 
Qualifiers: [@javax.enterprise.inject.Default()]
for injection into Field Injection Point, field name :  anotherBean, Bean Owner : [null]

我们在测试@ViewScoped bean时遇到类似的困难。我们通过在测试中自己创建了注入来解决这个问题。

Bean实例本身是在测试中创建的，然后通过使用反射将所有依赖项插入到该实例中。这适用于bean，entitymanger等

@RunWith(Arquillian.class)
public class ViewControllerTest {
@Inject private OtherBean otherBean;

private ViewController viewController;


@Deployment
public static WebArchive createDeployment() {
  return WebArchiveFactory.getDefaultWebarchArchive();
}

@Before
public void setup() throws Exception {
  viewController = new ViewController();
  TestHelper.setFacesContext(); // provide FacesContextMock
  TestHelper.inject(viewController, "otherBean", otherBean);
}
}

TestHelper看起来像这样

public class TestHelper {

public static void inject(Object bean, 
                          String fieldName, 
                          Object fieldValue) throws Exception {
  if (null == bean) {
    throw new IllegalArgumentException("Bean must not be null");
  }
  Field field;
  try {
    field = bean.getClass().getDeclaredField(fieldName);
  } catch (NoSuchFieldException e) {
    log.log(Level.SEVERE, "Could not find field for injection: " + fieldName);
    throw e;
  }
  field.setAccessible(true);
  field.set(bean, fieldValue);
}
}

Answer 2

最后，我不得不用一个老式的黑客解决这个问题。我找到了原始org.apache.webbeans.container.BeanManagerImpl来自的WebBeans context with scope type annotation @ViewScoped does not exist within current thread的来源。我在测试源中创建了这个类，然后我做了一些更改来解决问题。

最终，对于我的测试，我不关心范围。我正在测试方法运行并返回正确的逻辑/数据。因此，在类中，它会检查bean所在的范围类型并抛出异常。我只是检查它是否在Viewscoped，如果是，则将其更改为Dependent。这样就可以让我的测试工作了。

不是最好的解决方案，但它有效。
