是的。在这种情况下，服务必须具有范围会话。请参阅 http： //docs.spring.io/spring/docs/current/spring-framework-reference/html/beans.html#beans-factory-scopes-other

Yes. In that case, the service will have to have the scope "session". See http://docs.spring.io/spring/docs/current/spring-framework-reference/html/beans.html#beans-factory-scopes-other
