在使用 Glassfish 嵌入式插件使用 Arquillian 运行单元测试时，我收到以下 CDI 错误：

2015-09-18 06:25:24,376 DEBUG | main | org.jboss.weld.Reflection                               | WELD-000620: interface com.SupportedLocales is not declared @Target(METHOD, FIELD, PARAMETER, TYPE). Weld will use this annotation, however this may make the application unportable.

GRAVE: Exception during lifecycle processing  
org.glassfish.deployment.common.DeploymentException: CDI deployment failure:WELD-001408: Unsatisfied dependencies for type Set<Locale> with qualifiers @SupportedLocales  
  at injection point [BackedAnnotatedParameter] Parameter 1 of [BackedAnnotatedConstructor] @Inject protected com.MyClass(@SupportedLocales Set<Locale>)  
  at com.MyClass.<init>(MyClass.java:0)

带有限定符 @SupportedLocales 的 Set(Locale) 定义在已测试 WebArchive 中部署的模块中。存档内容是：

/WEB-INF/
/WEB-INF/lib/
/WEB-INF/lib/commons-lang3-3.3.2.jar
/WEB-INF/lib/commons-configuration-1.10.jar

/WEB-INF/classes/com/timm/common/cdi/web/i18n/
/WEB-INF/classes/com/timm/common/cdi/web/i18n/ShiroCurrentLocale.class
/WEB-INF/beans.xml

该对象由位于“common-cdi”模块中的生产者方法提供。同一个模块提供 CDI 扩展功能，如 ThreadScoped。Weld 在测试启动期间未发现此生产者，并且 Weld 未从“commons-cdi”模块中发现 bean。这怎么可能？我们可以在同一个模块中提供 CDI 扩展功能和 CDI bean 吗？

@SupportedLocales 在“commons-cdi”中声明：

@Qualifier  
@Target({  
        ElementType.FIELD, ElementType.PARAMETER, ElementType.METHOD  
})  
@Retention(RetentionPolicy.RUNTIME)  
public @interface SupportedLocales {  
}

生产者在“commons-cdi”中声明：

@Dependent  
public class I18NProducer {  
    @Produces  
    @ApplicationScoped  
    @Default  
    @SupportedLocales  
    public Set<Locale> getSupportedLocales() {  
        Set<Locale> supportedLocales;  
        supportedLocales = new HashSet<Locale>();  
        supportedLocales.add(Locale.US);  
        return supportedLocales;  
    }  
}

JUnit 测试用例定义：

@RunWith(Arquillian.class)
public class LocaleInjectionTest {

    @Deployment
    public static Archive<?> deploy() {
        final String moduleName = LocaleInjectionTest.class.getSimpleName();

        PomEquippedResolveStage resolver = Maven.resolver().loadPomFromFile("pom.xml");

        File[] libs = resolver.resolve("com.myname:commons-cdi").withTransitivity().asFile();

        WebArchive testWar = ShrinkWrap
                .create(WebArchive.class, moduleName + ".war")
                .addClass(MyCurrentLocale.class)
                .addAsLibraries(libs)
                .addAsWebInfResource(ArchiveUtils.getResourceBeanXMLWithAlternativeAndDiscoveryModeAnnotated(MyCurrentLocale.class),
                        "beans.xml");

        return testWar;
    }

    @Inject
    private CurrentLocale bean;

    @Test
    public void testInjection() throws Exception {
        ...
    }
}

MyCurrentLocale 类定义：

    @SessionScoped
    @Alternative
    public class MyCurrentLocale extends DefaultCurrentLocale implements Serializable {

        @Inject
        protected MyCurrentLocale(@SupportedLocales Set<Locale> supportedLocales) {
            super(supportedLocales);
        }
       ...
   }

声明有问题吗？

看起来您使用的是 GlassFish v3，因此您需要 jar 中的 beans.xml 文件，并且它也是一个 bean 存档。
