java.lang.RuntimeException：无法注入成员

Question

一段时间以来，我一直在尝试让 Arquillian 与 JPA 一起运行。

我进行了一些 DAO 测试，但是在继续编写剩余的测试时，此错误开始并影响了我正在编写的测试和之前运行良好的测试。

我认为这个堆栈跟踪中最重要的部分是：WELD-001408：MorphologicalAnalysisPersistenceFacade 类型的不满意依赖项这通常意味着并非MorphologicalAnalysisPersistenceFacade所需的所有依赖项都部署到 Weld 容器。要对此进行调试，我建议暂时将您的部署方法重写为：@Deploymentpublic static Archive<?> createDeployment() {&nbsp; &nbsp; JavaArchive archive = ShrinkWrap.create(JavaArchive.class, "morphological-analysis-data-access-object-test.jar")&nbsp; &nbsp; .addPackages(true, "br.com.cpmh.beacon")&nbsp; &nbsp; .addAsResource("test-persistence.xml", "META-INF/persistence.xml")&nbsp; &nbsp; .addAsResource(EmptyAsset.INSTANCE, ArchivePaths.create("beans.xml"));&nbsp; &nbsp; // print all included packages&nbsp; &nbsp; System.out.println(archive.toString(true));&nbsp; &nbsp; return archive;}这将打印出部署到容器的所有类。这样，您可以调查是否有任何必需的类没有被部署，并在 createDeployment 方法中手动包含该类或包。
