      public boolean preHandle(HttpServletRequest request, HttpServletResponse response, Object handler) throws Exception
      Description copied from interface: HandlerInterceptor
      Interception point before the execution of a handler. Called after HandlerMapping determined an appropriate handler object, but before HandlerAdapter invokes the handler.

      DispatcherServlet processes a handler in an execution chain, consisting of any number of interceptors, with the handler itself at the end. With this method, each interceptor can decide to abort the execution chain, typically sending an HTTP error or writing a custom response.

      Note: special considerations apply for asynchronous request processing. For more details see AsyncHandlerInterceptor.

      The default implementation returns true.

      Specified by:
      preHandle in interface HandlerInterceptor
      request - current HTTP request
      response - current HTTP response
      handler - chosen handler to execute, for type and/or instance evaluation
      true if the execution chain should proceed with the next interceptor or the handler itself. Else, DispatcherServlet assumes that this interceptor has already dealt with the response itself.
      Exception - in case of errors
