Question

Can I configure Spring in such a way that I add a property, “isHttps” to the request, and this property can be accessed from anywhere in the code, e.g. a bean class:

    public class MyItem{
       public String getImageUrl(){
          if (isHttps){
            //return https url 
          }
      //return http url;
       }
    }

I can do this using ThreadLocal, but I would like to avoid taking that route.

Another alternative:

You can get the current request as follows:

    ServletRequestAttributes sra = (ServletRequestAttributes)RequestContextHolder.getRequestAttributes();
    HttpServletRequest req = sra.getRequest();     

This uses thread-local under the covers.

If you are using Spring MVC that’s all you need. If you are not using Spring MVC then you will need to register a RequestContextListener or RequestContextFilter in your web.xml.
