作为业务逻辑.我正在尝试使用注释(@Scope(“session”))将会话范围设置为我的一个spring bean,但是我得到了这个异常:
SEVERE: Context initialization failed org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'handleFiles': Injection of autowired dependencies failed; nested exception is org.springframework.beans.factory.BeanCreationException: Could not autowire field: private creazione.util.FTPOperations creazione.components.HandleOldFiles.operations; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'ftpOperations': Scope 'session' is not active for the current thread; consider defining a scoped proxy for this bean if you intend to refer to it from a singleton; nested exception is java.lang.IllegalStateException: No thread-bound request found: Are you referring to request attributes outside of an actual web request, or processing a request outside of the originally receiving thread? 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 </listener-class> </listener> <filter> <filter-name>requestContextFilter</filter-name> <filter-class>org.springframework.web.filter.RequestContextFilter</filter-class> </filter> <filter-mapping> <filter-name>requestContextFilter</filter-name> <url-pattern>/*</url-pattern> <dispatcher>REQUEST</dispatcher> <dispatcher>INCLUDE</dispatcher> <dispatcher>FORWARD</dispatcher> </filter-mapping>
似乎没什么用.我究竟做错了什么?
谢谢!
尝试定义必须作为会话注入的bean与aop:scoped-proxy.
<bean id="ftpOperations" class="..." scope="session"> <aop:scoped-proxy/> </bean>
如果相关命名空间不存在,则还要添加它:
<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 ...
