详解使用Spring Security OAuth 实现OAuth 2.0 授权

@Configuration
public class SecurityConfiguration extends WebSecurityConfigurerAdapter {

  @Override
  protected void configure(HttpSecurity http) throws Exception {
    http.formLogin()
        .and().csrf().disable()
        .authorizeRequests().anyRequest().authenticated();
  }

  @Override
  public void configure(WebSecurity web) throws Exception {
    super.configure(web);
  }

  @Override
  protected void configure(AuthenticationManagerBuilder auth) throws Exception {
    auth.inMemoryAuthentication().withUser("lyt").password("lyt").authorities("ROLE_USER")
        .and().withUser("admin").password("admin").authorities("ROLE_ADMIN");
  }

  @Bean
  @Override
  public AuthenticationManager authenticationManagerBean() throws Exception {
    return super.authenticationManagerBean();
  }
}

@EnableAuthorizationServer
@Configuration
public class AuthorizationServerConfiguration extends AuthorizationServerConfigurerAdapter {

  @Override
  public void configure(ClientDetailsServiceConfigurer clients) throws Exception {
    clients.inMemory().withClient("client")
        .scopes("read","write")
        .secret("secret")
        .authorizedGrantTypes("authorization_code","password","implicit","client_credentials");}

  @Override

    super.configure(security);
  }

  @Override
  public void configure(AuthorizationServerEndpointsConfigurer endpoints) throws Exception {
    endpoints.authenticationManager(authenticationManager);
  }

  @Autowired
  @Qualifier("authenticationManagerBean")
  private AuthenticationManager authenticationManager;
}

@EnableGlobalMethodSecurity(prePostEnabled = true)
@EnableResourceServer
@Configuration
public class ResourceServerConfiguration extends ResourceServerConfigurerAdapter {
 @Override
 public void configure(HttpSecurity http) throws Exception {
 http.antMatcher("/oauth2/api/**").authorizeRequests()
