I have a REST API webservice which injects a singleton bean. This bean needs to know about the HTTPServletRequest. So i have created another bean called RequestServiceImpl which has HTTPServlerRequest injected. 

public class RequestServiceImpl implements RequestService
{
    @Autowired
    private HttpServletRequest request;

}

web-context contains bean definition as 

<bean id="requestService" class="com.RequestServiceImpl" scope="request">
     <aop:scoped-proxy/>
</bean>

This requestService is injected into another singleton bean. I do see the requestservice bean being injected correctly but the HTTPServletRequest object is always null. I am not sure where am i going wrong

HTTPServletRequest is an Interface. You cannot have instance of interface. You may inject class that implements HTTPServletRequest and that is HttpServletRequestWrapper. You could have your reference implementation as well if you want.

  • Not sure i understand what you mean. Do you mean to inject the request as @Autowired private HttpServletRequestWrapper request; – user2066789 Jun 03 '15 at 13:40
