preHandle
public boolean preHandle(HttpServletRequest request, HttpServletResponse response, Object handler) throws ServletException, IOException 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 interfaceHandlerInterceptor
- Parameters:
request
- current HTTP requestresponse
- current HTTP responsehandler
- chosen handler to execute, for type and/or instance evaluation- Returns:
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.- Throws:
ServletException
IOException
