如何使用拦截器修改HttpServletRequest

Question

如何使用拦截器修改请求URL？尽我所能 看到没有设置方法。

public class RequestInterceptor extends HandlerInterceptorAdapter {

@Override
public boolean preHandle(HttpServletRequest request, HttpServletResponse response, Object handler) throws Exception {

    // Need to modify this -> request.getRequestURL();
    return super.preHandle(request, response, handler);
}

}
