话不多说,先上图

springSecurityOauth2在springSecurity基础上加了: 几个端点 endPoint,  客户端clients ,  在springSecurity基础上添加两者的配置.

@Configuration
@Order(0)
@Import({ ClientDetailsServiceConfiguration.class, AuthorizationServerEndpointsConfiguration.class })
public class AuthorizationServerSecurityConfiguration extends WebSecurityConfigurerAdapter {

	@Autowired
	private List<AuthorizationServerConfigurer> configurers = Collections.emptyList();

	@Autowired
	private ClientDetailsService clientDetailsService;

	@Autowired
	private AuthorizationServerEndpointsConfiguration endpoints;

	@Autowired
	public void configure(ClientDetailsServiceConfigurer clientDetails) throws Exception {
		for (AuthorizationServerConfigurer configurer : configurers) {
			configurer.configure(clientDetails);
		}
	}

	@Override
	protected void configure(AuthenticationManagerBuilder auth) throws Exception {
		// Over-riding to make sure this.disableLocalConfigureAuthenticationBldr = false
		// This will ensure that when this configurer builds the AuthenticationManager it will not attempt
		// to find another 'Global' AuthenticationManager in the ApplicationContext (if available),
		// and set that as the parent of this 'Local' AuthenticationManager.
		// This AuthenticationManager should only be wired up with an AuthenticationProvider
		// composed of the ClientDetailsService (wired in this configuration) for authenticating 'clients' only.
	}

	@Override
	protected void configure(HttpSecurity http) throws Exception {
		AuthorizationServerSecurityConfigurer configurer = new AuthorizationServerSecurityConfigurer();
		FrameworkEndpointHandlerMapping handlerMapping = endpoints.oauth2EndpointHandlerMapping();
		http.setSharedObject(FrameworkEndpointHandlerMapping.class, handlerMapping);
		configure(configurer);
		http.apply(configurer);
		String tokenEndpointPath = handlerMapping.getServletPath("/oauth/token");
		String tokenKeyPath = handlerMapping.getServletPath("/oauth/token_key");
		String checkTokenPath = handlerMapping.getServletPath("/oauth/check_token");
		if (!endpoints.getEndpointsConfigurer().isUserDetailsServiceOverride()) {
			UserDetailsService userDetailsService = http.getSharedObject(UserDetailsService.class);
			endpoints.getEndpointsConfigurer().userDetailsService(userDetailsService);
		}
		// @formatter:off
		http
        	.authorizeRequests()
            	.antMatchers(tokenEndpointPath).fullyAuthenticated()
            	.antMatchers(tokenKeyPath).access(configurer.getTokenKeyAccess())
            	.antMatchers(checkTokenPath).access(configurer.getCheckTokenAccess())
        .and()
        	.requestMatchers()
            	.antMatchers(tokenEndpointPath, tokenKeyPath, checkTokenPath)
        .and()
        	.sessionManagement().sessionCreationPolicy(SessionCreationPolicy.NEVER);
		// @formatter:on
		http.setSharedObject(ClientDetailsService.class, clientDetailsService);
	}

	protected void configure(AuthorizationServerSecurityConfigurer oauthServer) throws Exception {
		for (AuthorizationServerConfigurer configurer : configurers) {
			configurer.configure(oauthServer);
		}
	}

}

最明显的三个端点

        String tokenEndpointPath = handlerMapping.getServletPath("/oauth/token");
        String tokenKeyPath = handlerMapping.getServletPath("/oauth/token_key");
        String checkTokenPath = handlerMapping.getServletPath("/oauth/check_token"); 

配置了访问规则

AuthorizationEndpoint  不需要认证就可以访问的.
