如何在Springbean中实现@ViewScope
如何在用spring的@component注释的bean中实现jsf的视图范围？ 我想在spring中创建自定义范围，它的功能与jsf的@ViewScope相同。 下面给出了我的自定义实现如何在Springbean中实现@ViewScope,spring,jsf-2,Spring,Jsf 2,如何在用spring的@component注释的bean中实现jsf的视图范围？ 我想在spring中创建自定义范围，它的功能与jsf的@ViewScope相同。 下面给出了我的自定义实现 import java.util.Map; import javax.faces.context.FacesContext; import org.springframework.beans.factory.ObjectFactory; import org.springframework.beans.f

我已经更新了上面的错误消息。只有在使用@Scope（“视图”）时，才会出现此错误。如果我正在使用@Scope（“请求”）或没有提供任何作用域，它将起作用。我创建的自定义视图范围是否有任何问题。我遗漏了什么吗？我更改了附加费列表
@Component("surchargeListBean")
@Scope("view")
public class SurchargeListBean implements Serializable{
@Autowired
ISurchargeService surchargeService;
