I am trying to implement a authentication-server using spring boot, spring cloud security and spring cloud oauth2.
I am getting below error when I try to hit http://localhost:8080/auth/oauth/token from postman
{ "error": "unauthorized", "error_description": "Full authentication is required to access this resource" }
Below is my pom.xml

Starter(Main) class:
package com.teckink.tp.authserver;
import java.util.HashMap;
import java.util.Map;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.security.core.authority.AuthorityUtils;
import org.springframework.security.oauth2.config.annotation.web.configuration.EnableAuthorizationServer;
import org.springframework.security.oauth2.config.annotation.web.configuration.EnableResourceServer;
import org.springframework.security.oauth2.provider.OAuth2Authentication;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
@SpringBootApplication
@RestController
@EnableResourceServer
@EnableAuthorizationServer
public class App {
@RequestMapping(value = { "/user" }, produces = "application/json")
public Map<String, Object> user(OAuth2Authentication user) {
Map<String, Object> userInfo = new HashMap<>();
userInfo.put("user", user.getUserAuthentication().getPrincipal());
userInfo.put("authorities", AuthorityUtils.authorityListToSet(user.getUserAuthentication().getAuthorities()));
return userInfo;
}
public static void main(String[] args) {
SpringApplication.run(App.class, args);
}
}
OAuth2Config class which defines client and its secret:
package com.teckink.tp.authserver.security;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.Configuration;
import org.springframework.security.authentication.AuthenticationManager;
import org.springframework.security.core.userdetails.UserDetailsService;
import org.springframework.security.oauth2.config.annotation.configurers.ClientDetailsServiceConfigurer;
import org.springframework.security.oauth2.config.annotation.web.configuration.AuthorizationServerConfigurerAdapter;
import org.springframework.security.oauth2.config.annotation.web.configurers.AuthorizationServerEndpointsConfigurer;
@Configuration
public class OAuth2Config extends AuthorizationServerConfigurerAdapter {
@Autowired
private AuthenticationManager authenticationManager;
@Autowired
private UserDetailsService userDetailsService;
@Override
public void configure(ClientDetailsServiceConfigurer clients) throws Exception {
clients.inMemory()
.withClient("eagleeye")
.secret("thisissecret")
.authorizedGrantTypes("refresh_token", "password", "client_credentials")
.scopes("webclient", "mobileclient");
}
@Override
public void configure(AuthorizationServerEndpointsConfigurer endpoints) throws Exception {
endpoints
.authenticationManager(authenticationManager)
.userDetailsService(userDetailsService);
}
}
WebSecurityConfigurer class which defines in-memory user, password and roles:
package com.teckink.tp.authserver.security;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.security.authentication.AuthenticationManager;
import org.springframework.security.config.annotation.authentication.builders.AuthenticationManagerBuilder;
import org.springframework.security.config.annotation.web.configuration.WebSecurityConfigurerAdapter;
import org.springframework.security.core.userdetails.UserDetailsService;
@Configuration
public class WebSecurityConfigurer extends WebSecurityConfigurerAdapter {
@Override
@Bean
public AuthenticationManager authenticationManagerBean() throws Exception {
return super.authenticationManagerBean();
}
@Override
@Bean
public UserDetailsService userDetailsServiceBean() throws Exception {
return super.userDetailsServiceBean();
}
@Override
protected void configure(AuthenticationManagerBuilder auth) throws Exception {
auth
.inMemoryAuthentication()
.withUser("john.carnell").password("password1").roles("USER")
.and()
.withUser("william.woodward").password("password2").roles("USER", "ADMIN");
}
}
I am calling Rest API from POSTMAN as below- Request with authentication screen show as below :
