Question

我需要在服务模块中将表单Spring注释切换为CDI注释。一切正常，但实体管理器为空。如果我用@Autowire注释存储库一切都很好（注入实体管理器）。当我切换到@Inject时，实体管理器为空，我不明白为什么？

这是spring context config：

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xmlns:context="http://www.springframework.org/schema/context"
       xsi:schemaLocation="http://www.springframework.org/schema/beans   http://www.springframework.org/schema/beans/spring-beans-3.0.xsd
        http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd">

    <!-- Scan service classes for beans -->
    <context:component-scan
            base-package="com.monitoring.facade, com.monitoring.indication, com.monitoring.app"
            annotation-config="false">
    </context:component-scan>
</beans>

服务类：

@Named
public class IndicatorTreeService implements Serializable{
    //@Autowire - everything ok
    @Inject
    private IndicatorRepository indicatorRepository;

    @Inject
    private IndicatorTreeBuilder indicatorTreeBuilder;

    public List<AbstractIndicatorTreeItem> getIndicatorTreeItems(){
        List<IndicatorVO> indicators = indicatorRepository.getIndicatorQuery().getResultList();
        return indicatorTreeBuilder.buildTree(indicators);
    }
}

存储库：

@Named
public class IndicatorRepository{
    @PersistenceContext
    private EntityManager em;

    public IndicatorQuery getIndicatorQuery(){
        return new IndicatorQuery(em);
    }
}

从@Autowired切换到@Inject后，EntityManager在存储库中为空
