java - 焊接-001408 : Unsatisfied dependencies for repositories from Spring Data

Question

我当前的工作是将我的 Java EE 应用程序从 Jboss 7 服务器迁移到 Wildfly 10。我在集成 CDI 和 Spring-Data 时遇到问题。我使用与 Jboss 7 相同的配置。当我尝试将应用程序部署到 Wildfly 服务器时，我收到与将 spring 数据存储库注入(inject)某些 CDI 和 EJB beans 相关的错误。

错误看起来像这样:

 org.jboss.weld.exceptions.DeploymentException: WELD-001408: Unsatisfied dependencies for type StudentExtTrainingRepository with qualifiers @Default
  at injection point [BackedAnnotatedField] @Inject private pl.mynetwork.mylearning.logic.historyTraining.HistoryTrainingService.studentExtTrainingRepository
  at pl.mynetwork.mylearning.logic.historyTraining.HistoryTrainingService.studentExtTrainingRepository(HistoryTrainingService.java:0)

我根据 spring data 配置指南配置了我的应用程序，我在这里找到了 https://docs.spring.io/spring-data/jpa/docs/current/reference/html/#jpd.misc.cdi-integration但在野蝇上它不起作用。

我有这样的实体管理器生产者类

@Dependent
public class SpringDataConfigurationProducer {  


  @Produces
  @ApplicationScoped
  public EntityManagerFactory createEntityManagerFactory() {
    return Persistence.createEntityManagerFactory("base-pu");
  }

  @Produces
  @RequestScoped
  public EntityManager createEntityManager(EntityManagerFactory entityManagerFactory) {
    return entityManagerFactory.createEntityManager();
  } 
}

当然，我的项目中的 META-INF 目录下有文件 beans.xml。

存储库，我尝试注入(inject)的内容如下所示:

@Repository
@Transactional
@Dependent
public interface StudentExtTrainingRepository extends JpaRepository<StudentExtTraining, Long> {
}

我想要注入(inject)存储库的服务看起来:

@Service
public class HistoryTrainingService {

  @Inject
  private StudentExtTrainingRepository studentExtTrainingRepository;
}

我有单独的 Spring 数据存储库项目和单独的服务/EJB 项目。两者都打包到一个 EAR 中。有人有什么建议吗？我花了很多时间解决这个问题，但找不到解决方案。

Answer 1

也添加这个类。

class CdiConfig {    
  @Produces
  @RequestScoped
  @PersistenceContext
  public EntityManager entityManager;
}
