您好，这可能是一个关于spring自动布线的相同问题，但我仍然找不到解决方案

我试图使用JSF2.2、Spring4.01和Hibernate创建基本的CRUD操作。在register.xhtml中，如果我单击register按钮，那么它应该将

firstname

（从现在起）保存到数据库中

我有以下资料：

注册页面（

register.xhtml

）

注册操作

（控制器）

RegistrationEntity

（目前只有一个字段的实体类，

firstName

）

LoginRegistrationServiceImpl

（一个服务类）——这实现了接口

LoginRegistrationService

部署时，我会遇到以下异常：

com.sun.faces.mgbean.ManagedBeanCreationException: Cant instantiate class: Controllers.RegistrationAction.
Caused by: org.springframework.beans.factory.BeanCreationException: Injection of autowired dependencies failed for class [class Controllers.RegistrationAction]

我尝试了以下更改

我单独创建如下：

我使用了

@Configuration

和

@ComponentScan（“Serviceimplementations”）

而不是在配置文件中声明

最初，我在注册操作中使用了

@ManagedBean

和

@Controller

。之后，我改为

SpringBeanAutowiringSupport

注意：我没有参数化构造函数。我搜索了许多相关的主题，这可能是一个愚蠢的错误，但我仍然不知道如何解决它

RegistrationAction.java：

@ManagedBean（name=“register”）
@配置
@组件扫描（“服务实现”）
public class RegistrationAction扩展了SpringBeanAuthoringSupport实现了可序列化{
私人登录注册ERIMPL LRINTERFAE；
公共登录注册ERIMPL getLrInterfcae（）{
返回LRCAE；
}
@自动连线
public void setlriffcae（LoginRegistrationsPerimpl lriffcae）{
this.lriffcae=lriffcae；
System.out.println（“接口对象--”+LRINTERFAE）；
}
}

LoginRegistrationImpl.java：

@服务（“lriffcae”）
公共类LoginRegistrationSerImpl实现LoginRegistrationService{
@凌驾
公共无效存储用户（注册实体注册）{
系统输出打印项次（“impl”）；
}
}

Register.xhtml：

输出：
