无法在Java EE 7堆栈上获取Spring数据JPA+CDI

Question

我正在尝试让Spring data JPA与EJB和CDI（Java EE 7）一起工作。嗯，我遵循了文档(http://docs.spring.io/spring-data/jpa/docs/1.4.2.release/reference/html/jpa.repositories.html#jpd.misc.cdi-integration)，但仍然无法将我的存储库注入到无状态EJB中。代码如下：

@Configuration
@EnableJpaRepositories
public class EntityManagerFactoryProducer {

@Produces
@ApplicationScoped
public EntityManagerFactory entityManagerFactory() {
    return Persistence.createEntityManagerFactory("mypu");
}

public void close(@Disposes EntityManagerFactory entityManagerFactory) {
    entityManagerFactory.close();
}
}

public interface TipoFolhaRepository extends JpaRepository<TipoFolha, Long> {

List<TipoFolha> findByNome(String nome);

TipoFolha findByTipo(String tipo);
}

@Stateless
public class TipoFolhaFacade extends AbstractFacade<TipoFolha> {

@Inject
TipoFolhaRepository tpRepo;

@Override
public  List<TipoFolha> findAll(){
    return tpRepo.findAll();
}
}

您需要在存储库类所在的模块中使用bean-discovery-mode=“all”启用CDI。这意味着在META-INF文件夹中创建一个beans.xml，内容如下：

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://xmlns.jcp.org/xml/ns/javaee"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee
       http://xmlns.jcp.org/xml/ns/javaee/beans_1_1.xsd"
       bean-discovery-mode="all">
</beans>
