Examples of org.springframework.web.servlet.HandlerInterceptor.preHandle()

org.springframework.web.servlet.HandlerInterceptor.preHandle()
Intercept 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 a HTTP error or writing a custom response. @param request current HTTP request @param response current HTTP response @param handler chosen handler to execute, for type and/or instance evaluation @return true if the execution chain should proceed with thenext interceptor or the handler itself. Else, DispatcherServlet assumes that this interceptor has already dealt with the response itself. @throws Exception in case of errors
