I have implemented Spring boot Oauth 2 security it works fine but when I try to get access token (if expired) from refresh token it gives me an error

{

    "error": "unauthorized",

    "error_description": "admin"

}

Console Log

Handling error: UsernameNotFoundException, admin

Following is my code

1.WebSecurityConfigure

@Configuration

@EnableWebSecurity

public class EmployeeSecurityConfiguration extends WebSecurityConfigurerAdapter {



    @Override

    public void configure(WebSecurity web) throws Exception {

        web.ignoring().antMatchers("/resources/**");

    }

    @Override

    protected void configure(HttpSecurity http) throws Exception {

        http.authorizeRequests().antMatchers("/").permitAll().antMatchers("/user/getEmployeesList")

            .hasAnyRole("USER").anyRequest().authenticated().and().formLogin()

            .permitAll().and().logout().permitAll();

        http.csrf().disable();

    }



    @Override

    public void configure(AuthenticationManagerBuilder authenticationMgr) throws Exception {

        authenticationMgr.inMemoryAuthentication().withUser("admin").password("admin")

            .authorities("ROLE_USER");

    ;

    }

}

2.AuthorizationServerConfigure

@Configuration

@EnableAuthorizationServer

public class AuthorizationServerConfig extends AuthorizationServerConfigurerAdapter {



    @Autowired

    private AuthenticationManager authenticationManager;





     @Override

        public void configure(AuthorizationServerSecurityConfigurer security) throws Exception {

            security

                    .tokenKeyAccess("permitAll()")

                    .checkTokenAccess("isAuthenticated()")

                    .allowFormAuthenticationForClients();

        }



    @Override

    public void configure(ClientDetailsServiceConfigurer clients) throws Exception {

        clients.inMemory().withClient("MagicUser").authorizedGrantTypes("authorization_code", "refresh_token","password")

                .authorities("CLIENT").scopes("openid", "read", "write", "trust").resourceIds("oauth2-resource")

                .redirectUris("http://10.9.6.31:8090/showEmployees").accessTokenValiditySeconds(5000).secret("secret")

                .refreshTokenValiditySeconds(50000);



    }

    @Override

    public void configure(AuthorizationServerEndpointsConfigurer endpoints) throws Exception {

        endpoints.authenticationManager(authenticationManager)

                .allowedTokenEndpointRequestMethods(HttpMethod.GET, HttpMethod.POST);

        ;

    }

}

Please help me to figure out this issue

Access token request (if expired)

    http://10.9.6.31:8091/oauth/token

    Body parameter

   grant_type=refresh_token

  refresh_token=78d2ab82-46a2-4b70-a9e8-e3f9e5ddfec6

You might have to send an authorization header in the request to authenticate the client.
Check OAuth client authentication and Refreshing an access token specifications in OAuth 2.0 specification.
