Springboot Unified Exception Handling

Unified Exception Handling:

@ControllerAdvice Public classGlobalexceptionhandler {PrivateLogger Logger =Loggerfactory.getlogger (GetClass ()); /** * Handle Custom exceptions*/@ExceptionHandler (authexception.class) @ResponseBody PublicR handlerrexception (authexception e) {r R=NewR (); R.put ("Code", E.getcode ()); R.put ("msg", E.getmessage ()); returnR; } @ExceptionHandler (Exception.class) @ResponseBody PublicR handleexception (Exception e) {logger.error (E.getmessage (), E); returnR.error (); }}

Now the internet is generally a relatively simple wording

There are other ways:

 Public classControllerexceptionresolver extends Exceptionhandlerexceptionresolver {Private StaticFinal Logger LOG = Loggerfactory.getlogger (controllerexceptionresolver.class); protectedModelandview doresolvehandlermethodexception (httpservletrequest request, httpservletresponse response, Handlermethod Handlermethod, Exception Exception) {String URI=Request.getrequesturi (); Log.error ("Exception URL:"+ URI +", processing framework", exception); if(Exception instanceof stonesystemruntimeexception) {//TODO attacks or unusual access will occurStonesystemruntimeexception stoneruntimeexception =(stonesystemruntimeexception) exception; Basicres Res=Newbasicres ();            Res.setmsg (Stoneruntimeexception.getmsg ());            Res.setrescode (Stoneruntimeexception.getcode ());  This. Excutejson (response, RES); Log.error ("system Run-time exceptions", exception); } Else if(Exception instanceof stonebizzruntimeexception) {//TODO general Business ExceptionStonebizzruntimeexception stonebizzexception =(stonebizzruntimeexception) exception; Basicres Res=Newbasicres ();            Res.setmsg (Stonebizzexception.getmsg ());            Res.setrescode (Stonebizzexception.getcode ());  This. Excutejson (response, RES); Log.error ("Business Exception", exception); } Else {            //TODO Other unhandled exceptionsBasicres res =Newbasicres (); Res.setmsg ("system Update, please try again later");            Res.setrescode (ErrorCode.SYSTEM_EXCEPTION.getCode ());  This. Excutejson (response, RES); Log.error ("no exception defined", exception); }        return NewModelandview (); }    PrivateString Excutejson (httpservletresponse response, basicres res) {Try {            byte[] Jsonbytes =json.tojsonbytes (RES); String Exjson=NewString (jsonbytes, Sysconstant.charset_utf8); Response.setcontenttype ("Application/json"); Response.setcharacterencoding ("UTF-8");            Response.getwriter (). write (Exjson); returnExjson; } Catch(Exception ex) {ex.printstacktrace (); }        return NULL; }}

Replace default:

@Configuration Public classInterceptorconfig extends Webmvcconfigureradapter {@Override Public voidExtendhandlerexceptionresolvers (listexceptionresolvers)        {super.extendhandlerexceptionresolvers (exceptionresolvers); Exceptionresolvers.add ( This. Getcontrollerexceptionresolver ()); } @Bean Publiccontrollerexceptionresolver Getcontrollerexceptionresolver () {return NewControllerexceptionresolver (); }}

Inheritance implements the Exceptionhandlerexceptionresolver class, which is generally seen in Springmvc, but can still be used in Springboot
