@Autowired成员变量的Spring crudepository为null

我是新来的春季JPA。我正在尝试使用hibernate+SpringJPA。为此，我在下面创建了存储库

package com.raptorservice.da.dal;

import com.raptorservice.da.objects.ClientDO;
import org.springframework.data.repository.CrudRepository;

public interface ClientRepository extends CrudRepository<ClientDO, String> {    
}

但是clientRepository总是空的。我错过了什么？为什么clientRepository没有自动连接

我检查了日志，没有发现任何明显的问题。请帮忙

提前感谢。

我认为缺少

，需要此注释才能在应用程序上下文中注册实例

如果您已使用 xml配置中的注释

看

通常，如果字段值为null且未发生异常，则意味着该对象不是Springbean（在其他地方实例化），或者不是由IoC容器进行后处理（可能后处理器已在中注册）

---

由于bean被急切地初始化为单例，并且默认情况下，

@Autowired

注释的required属性设置为true，因此如果bean被处理，Spring很可能在容器初始化期间抛出异常。

嗨，Boris，感谢您的响应。添加后，我看到它至少尝试注入我的成员变量。然而，它失败了，抱怨其中一个bean没有注册。我想我得研究一下元件扫描。但是谢谢你的提示和链接。你是如何解决你的问题的？
