exception spring boot schedule

Question

I made a schedule that execute itself every 5 minutes here is it

package com.start.services;
import ...    
@Component
public class ScheduledTasks { 
    @Autowired
    AlertServiceImpl alertServ ;
    private static final Logger log = LoggerFactory.getLogger(ScheduledTasks.class);

    private static final SimpleDateFormat dateFormat = new SimpleDateFormat("HH:mm:ss");

    @Scheduled(fixedRate = 1000*60*5) // every 5 minutes
    public void reportCurrentTime() {

        log.info("Refreshing started at {}", dateFormat.format(new Date()));
        alertServ.refreshAlerts();

    }
}

But I get this strange exception when it executes a twitter service :

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'scopedTarget.twitter': Scope 'request' 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.

This happens because external services, like your twitter integration, run in scope 'request', but scheduled tasks are meant to run in other scopes, like application scope; spring, by design's choice, can't know when the request starts and when it ends. But there are a couple of solutions/workarounds, like implementing a custom ResquestAttributes and a custom job - or even a custom request scope.
