Java 在Springbean中使用会话范围
我使用JSF2作为视图,使用Spring作为业务逻辑。我试图使用注释(@scope(“session”)将会话范围设置为我的一个Springbean,但我遇到了以下异常:Java 在Springbean中使用会话范围,java,spring,jsf-2,Java,Spring,Jsf 2,我使用JSF2作为视图,使用Spring作为业务逻辑。我试图使用注释(@scope(“session”)将会话范围设置为我的一个Springbean,但我遇到了以下异常: SEVERE: Context initialization failed org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'handleFiles': Injection of aut

If you are actually operating within a web request and still receive this message, your code is probably running outside of DispatcherServlet/DispatcherPortlet: In this case, use RequestContextListener or RequestContextFilter to expose the current request.
我知道RequestContextListener。它在我的web.xml中。我还添加了RequestContextFilter:
<listener>
<listener-class>
org.springframework.web.context.ContextLoaderListener
</listener-class>
</listener>
<listener>
<listener-class>
org.springframework.web.context.request.RequestContextListener

似乎什么都不管用。我做错了什么?
谢谢大家! 尝试使用aop:scoped proxy将必须注入的bean定义为会话
<bean id="ftpOperations" class="..." scope="session">
<aop:scoped-proxy/>
</bean>
如果相关名称空间尚未出现,请添加该名称空间:
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:aop="http://www.springframework.org/schema/aop"
...
xsi:schemaLocation="
http://www.springframework.org/schema/aop
http://www.springframework.org/schema/aop/spring-aop-3.0.xsd
...
如果使用基于注释的配置,只需在主配置xml中更改此标记:
<context:component-scan base-package="my.package"/>
这是我的工作。
详情如下:
另外,如果您要通过上下文xml配置创建bean,下面是另一个示例:
<bean id="somebean" class="com.package.beans" scope="session">
<aop:scoped-proxy/>
</bean>
是的,但我正在使用注释。我有很多SpringBean要在applicationContext.xml中编写。是否有与之等效的注释?试着看看这个问题仍然不太有效…我添加了@Scope(value=“session”,proxyMode=ScopedProxyMode.INTERFACES),我为每个Springbean重构了一个接口,但现在自动连线不再识别我的bean…错误消息是什么?请记住,您可以指定一个限定符来帮助连接过程,例如:@Autowired@Qualifier(“beanName”)是的,我使用了该限定符;异常是:由以下原因引起:org.springframework.beans.factory.NoSuchBeanDefinitionException:找不到依赖项类型为[creazione.util.FTPOperations]的匹配bean:至少需要1个符合此依赖项autowire候选项条件的bean。依赖项注释:{@org.springframework.beans.factory.annotation.Autowired(required=true),@org.springframework.beans.factory.annotation.Qualifier(value=ftpOperations)}这对我不起作用。我得到相同错误的三种方法都无法连接。它不是自动连接的原因有很多——范围设置中断,缺少cglib it类路径(如果您是没有接口的自动连接)。有关详细信息,请参阅错误消息。
@Component
@Scope(value = "session", proxyMode = ScopedProxyMode.TARGET_CLASS)
<bean id="somebean" class="com.package.beans" scope="session">
<aop:scoped-proxy/>
</bean>
