Spring Boot Remove Whitelabel Error Page -

i'm trying remove white label error page, i've done created controller mapping "/error",

@restcontroller public class indexcontroller {      @requestmapping(value = "/error")     public string error() {         return "error handling";     }  } 

but i"m getting error.

exception in thread "awt-eventqueue-0" org.springframework.beans.factory.beancreationexception: error creating bean name 'requestmappinghandlermapping' defined in class path resource   [org/springframework/web/servlet/config/annotation/delegatingwebmvcconfiguration.class]: invocation  of init method failed; nested exception java.lang.illegalstateexception: ambiguous mapping found. cannot map 'basicerrorcontroller' bean method  public org.springframework.http.responseentity<java.util.map<java.lang.string, java.lang.object>>  org.springframework.boot.autoconfigure.web.basicerrorcontroller.error(javax.servlet.http.httpservletr equest) {[/error],methods=[],params=[],headers=[],consumes=[],produces=[],custom=[]}: there 'indexcontroller' bean method 

don't know whether i'm doing wrong. please advice.

edit:

already added error.whitelabel.enabled=false application.properties file, still getting same error

you need change code following:

@restcontroller public class indexcontroller implements errorcontroller{      private static final string path = "/error";      @requestmapping(value = path)     public string error() {         return "error handling";     }      @override     public string geterrorpath() {         return path;     } } 

your code did not work, because spring boot automatically registers basicerrorcontroller spring bean when have not specified implementation of errorcontroller.
