public boolean preHandle(HttpServletRequest request,

throws Exception
HandlerInterceptorDispatcherServlet 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 a HTTP error or writing a custom response.
preHandle in interface HandlerInterceptorrequest - current HTTP requestresponse - current HTTP responsehandler - 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

HttpServletResponse response,
Object handler,
ModelAndView modelAndView)
throws Exception
HandlerInterceptorDispatcherServlet 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 post-process an execution, getting applied in inverse order of the execution chain.
