How to get ServletConfig within Spring application?

try to autowired ServletConfig into current application, not ServletContext because an API ask for it.

I know user can get ServletContext by a ServletConfig servlet but how to do the other way around or taken from spring application

Rather than autowiring, trying implementing ServletConfigAware.

Edit:

I couldn't find an example that shows using ServletConfigAware in a real project. Essentially, you'd have a class that implemented this interface to obtain the ServletConfig.
You'd create a Spring bean from the class by annotating the class with @Component or declaring a bean in XML. When Spring creates the bean, it would invoke setServletConfig(ServletConfig servletConfig).

Once you had an instance of ServletConfig in your bean, you'd do whatever you need with it.

Your question was how to obtain the ServletConfig, but I think (correct me if I'm wrong) you are looking to integrate a legacy Servlet into your Spring Web MVC application. ServletWrappingController might be a better choice. I haven't ever used it myself, but it appears to be specifically designed for that purpose.
