Adding header in response in filter?

Question

I need to add the header in each response. I am planning to do below

public class MyFilter extends OncePerRequestFilter {

    @Override
    protected void d         


        

Answer 1

I use this in my project with Spring 3.0.x:

public class MyFilter extends OncePerRequestFilter {
    @Override
    protected void doFilterInternal(HttpServletRequest request, HttpServletResponse response, FilterChain filterChain) throws ServletException, IOException
    {
        response.addHeader("headerName", "headerValue");
        filterChain.doFilter(request, response);
    }
}

Works fine.
