How to add HttpServletRequest headers in HandlerInterceptorAdapter?
<p>I'm trying to add a Authorization header to my request as a temporary workaround while we are switching environments. I'm trying to handle it in a interceptor that extends HandlerInterceptorAdapter.</p>

<p>I used the MutableHttpServletRequest class made <a href="http://wilddiary.com/adding-custom-headers-java-httpservletrequest/" rel="noreferrer">here</a> in order to be able to add the header to the request, but it doesn't seem like there is any way you can actually modify the returned request in the interceptor. Any ideas?</p>

<p>EDIT: Or would I have to do this in a filter?</p>
