How to change spring security oauth2 default token endpoint?

Question

We have spring security oauth2 based application. Every thing is working fine. But i am failed to change default token endpoint from "/oauth/token" to "/external/oauth/token".

My spring-servlet.xml

<http pattern="/external/oauth/token" create-session="stateless"         authentication-manager-ref="clientAuthenticationManager"        use-expressions="true" xmlns="http://www.springframework.org/schema/security">       <intercept-url pattern="/external/oauth/token" access="isFullyAuthenticated()" />       <anonymous enabled="false" />       <http-basic entry-point-ref="clientAuthenticationEntryPoint" />       <!-- include this only if you need to authenticate clients via request parameters -->       <custom-filter ref="clientCredentialsTokenEndpointFilter" after="BASIC_AUTH_FILTER" />       <access-denied-handler ref="oauthAccessDeniedHandler"/> </http>  <oauth:authorization-server client-details-service-ref="clientDetails"          token-services-ref="tokenServices"          user-approval-handler-ref="userApprovalHandler" token-endpoint-url="/external/oauth/token">         <oauth:authorization-code />         <oauth:implicit />         <oauth:refresh-token />         <oauth:client-credentials />         <oauth:password /> </oauth:authorization-server> 

But the result when i access this endpoint is

{     error: "unauthorized"     error_description: "An Authentication object was not found in the SecurityContext" } 

am i missing any thing ? Please suggest.

With the version 2.0.5.RELEASE or above of spring-security-oauth2

In one line in java based configuration, tested and works fine, somehow it's overriding the RequestMapping value of the TokenEndpoint class.

@Configuration @EnableAuthorizationServer protected static class AuthorizationServerConfiguration extends AuthorizationServerConfigurerAdapter {                @Override         public void configure(AuthorizationServerEndpointsConfigurer endpoints) throws Exception {             endpoints                 .pathMapping("/oauth/token", "<your custom endpoint>")         } }
