前言
经过一段时间的学习Oauth2，在网上也借鉴学习了一些大牛的经验，推荐在学习的过程中多看几遍阮一峰的《理解OAuth 2.0》，经过对Oauth2的多种方式的实现，个人推荐Spring Security和Oauth2的实现是相对优雅的，理由如下：
1、相对于直接实现Oauth2，减少了很多代码量，也就减少的查找问题的成本。
2、通过调整配置文件，灵活配置Oauth相关配置。
3、通过结合路由组件（如zuul），更好的实现微服务权限控制扩展。
Oauth2概述
oauth2根据使用场景不同，分成了4种模式
在项目中我们通常使用授权码模式，也是四种模式中最复杂的，通常网站中经常出现的微博，qq第三方登录，都会采用这个形式。
Oauth2授权主要由两部分组成：
在实际项目中以上两个服务可以在一个服务器上，也可以分开部署。
准备阶段
核心maven依赖如下

<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>

<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-data-jpa</artifactId>
</dependency>
token的存储主流有三种方式，分别为内存、redis和数据库，在实际项目中通常使用redis和数据库存储。个人推荐使用mysql数据库存储。
初始化数据结构、索引和数据SQL语句如下：
--
-- Oauth sql -- MYSQL
--
Drop table if exists oauth_client_details;
create table oauth_client_details (
client_id VARCHAR(255) PRIMARY KEY,
resource_ids VARCHAR(255),
client_secret VARCHAR(255),
scope VARCHAR(255),
authorized_grant_types VARCHAR(255),
web_server_redirect_uri VARCHAR(255),
authorities VARCHAR(255),
access_token_validity INTEGER,
refresh_token_validity INTEGER,
additional_information TEXT,
autoapprove VARCHAR (255) default 'false'
) ENGINE=InnoDB DEFAULT CHARSET=utf8;
Drop table if exists oauth_access_token;
create table oauth_access_token (
token_id VARCHAR(255),
token BLOB,
authentication_id VARCHAR(255),
user_name VARCHAR(255),
client_id VARCHAR(255),
authentication BLOB,
refresh_token VARCHAR(255)
) ENGINE=InnoDB DEFAULT CHARSET=utf8;
Drop table if exists oauth_refresh_token;
create table oauth_refresh_token (
token_id VARCHAR(255),
token BLOB,
authentication BLOB
) ENGINE=InnoDB DEFAULT CHARSET=utf8;
Drop table if exists oauth_code;
create table oauth_code (
code VARCHAR(255),
authentication BLOB
) ENGINE=InnoDB DEFAULT CHARSET=utf8;
-- Add indexes
create index token_id_index on oauth_access_token (token_id);
create index authentication_id_index on oauth_access_token (authentication_id);
create index user_name_index on oauth_access_token (user_name);
create index client_id_index on oauth_access_token (client_id);
create index refresh_token_index on oauth_access_token (refresh_token);
create index token_id_index on oauth_refresh_token (token_id);
create index code_index on oauth_code (code);
-- INSERT DEFAULT DATA
INSERT INTO `oauth_client_details` VALUES ('dev', '', 'dev', 'app', 'authorization_code', 'http://localhost:7777/', '', '3600', '3600', '{"country":"CN","country_code":"086"}', 'TAIJI');
核心配置
核心配置主要分为授权应用和客户端应用两部分，如下：
授权应用主要配置如下：
application.properties链接已初始化Oauth2的数据库即可
Application启动类，授权服务开启配置和Spring Security配置，如下：
@SpringBootApplication
@AutoConfigureAfter(JacksonAutoConfiguration.class)
@Order(SecurityProperties.ACCESS_OVERRIDE_ORDER)
@EnableAuthorizationServer
public class Application extends WebSecurityConfigurerAdapter {
public static void main(String[] args) {
SpringApplication.run(Application.class, args);
}
// 启动的时候要注意，由于我们在controller中注入了RestTemplate，所以启动的时候需要实例化该类的一个实例
@Autowired
private RestTemplateBuilder builder;
// 使用RestTemplateBuilder来实例化RestTemplate对象，spring默认已经注入了RestTemplateBuilder实例
@Bean
public RestTemplate restTemplate() {
return builder.build();
}
@Configuration
public class WebMvcConfig extends WebMvcConfigurerAdapter {
@Override
public void addViewControllers(ViewControllerRegistry registry) {
registry.addViewController("/login").setViewName("login");
}
}
@Override
protected void configure(HttpSecurity http) throws Exception {
http.headers().frameOptions().disable();
http.authorizeRequests()
.antMatchers("/403").permitAll() // for test
.antMatchers("/login", "/oauth/authorize", "/oauth/confirm_access", "/appManager").permitAll() // for login
.antMatchers("/image", "/js/**", "/fonts/**").permitAll() // for login
.antMatchers("/j_spring_security_check").permitAll()
.antMatchers("/oauth/authorize").authenticated();
/*.anyRequest().fullyAuthenticated();*/
http.formLogin().loginPage("/login").failureUrl("/login?error").permitAll()
.and()
.authorizeRequests().anyRequest().authenticated()
.and().logout().invalidateHttpSession(true)
.and().sessionManagement().maximumSessions(1).expiredUrl("/login?expired").sessionRegistry(sessionRegistry());
http.csrf().csrfTokenRepository(CookieCsrfTokenRepository.withHttpOnlyFalse());
http.rememberMe().disable();
http.httpBasic();
}
}
资源服务开启，如下：
@Configuration
@EnableResourceServer
protected static class ResourceServerConfiguration extends ResourceServerConfigurerAdapter {
@Override
public void configure(HttpSecurity http) throws Exception {
http.antMatcher("/me").authorizeRequests().anyRequest().authenticated();
}
}
OAuth2认证授权服务配置，如下：
@Configuration
public class AuthorizationServerConfiguration extends AuthorizationServerConfigurerAdapter {
public static final Logger logger = LoggerFactory.getLogger(AuthorizationServerConfiguration.class);
@Autowired
private AuthenticationManager authenticationManager;
@Autowired
private DataSource dataSource;
@Bean
public TokenStore tokenStore() {
return new JdbcTokenStore(dataSource);
}
@Override
public void configure(AuthorizationServerEndpointsConfigurer endpoints) throws Exception {
endpoints.authenticationManager(authenticationManager);
endpoints.tokenStore(tokenStore());
// 配置TokenServices参数
DefaultTokenServices tokenServices = new DefaultTokenServices();
tokenServices.setTokenStore(endpoints.getTokenStore());
tokenServices.setSupportRefreshToken(false);
tokenServices.setClientDetailsService(endpoints.getClientDetailsService());
tokenServices.setTokenEnhancer(endpoints.getTokenEnhancer());
tokenServices.setAccessTokenValiditySeconds( (int) TimeUnit.MINUTES.toSeconds(10)); //分钟
endpoints.tokenServices(tokenServices);
}
@Override
public void configure(AuthorizationServerSecurityConfigurer oauthServer) throws Exception {
oauthServer.checkTokenAccess("isAuthenticated()");
oauthServer.allowFormAuthenticationForClients();
}
@Bean
public ClientDetailsService clientDetails() {
return new JdbcClientDetailsService(dataSource);
}
@Override
public void configure(ClientDetailsServiceConfigurer clients) throws Exception {
clients.withClientDetails(clientDetails());
/*
* 基于内存配置项
* clients.inMemory()
.withClient("community")
.secret("community")
.authorizedGrantTypes("authorization_code").redirectUris("http://tech.taiji.com.cn/")
.scopes("app").and() .withClient("dev")
.secret("dev")
.authorizedGrantTypes("authorization_code").redirectUris("http://localhost:7777/")
.scopes("app");*/
}
}
客户端应用主要配置如下：
application.properties中Oauth2配置，如下
security.oauth2.client.clientId=dev security.oauth2.client.clientSecret=dev security.oauth2.client.accessTokenUri=http://localhost:9999/oauth/token security.oauth2.client.userAuthorizationUri=http://localhost:9999/oauth/authorize security.oauth2.resource.loadBalanced=true security.oauth2.resource.userInfoUri=http://localhost:9999/me security.oauth2.resource.logout.url=http://localhost:9999/revoke-token security.oauth2.default.roleName=ROLE_USER
Oauth2Config配置，授权Oauth2Sso配置和Spring Security配置，如下：

}
授权成功回调类，认证成功用户落地，如下：

SavedRequest savedRequest = requestCache.getRequest(request, response);
if (savedRequest == null) {
super.onAuthenticationSuccess(request, response, authentication);
return;
}
String targetUrlParameter = getTargetUrlParameter();
if (isAlwaysUseDefaultTargetUrl()
|| (targetUrlParameter != null && StringUtils.hasText(request.getParameter(targetUrlParameter)))) {

//用户落地
private UserDto saveUser(Map userInfo) {

客户端应用，单点登录方法，如下：
@RequestMapping(value = "/loadToken", method = { RequestMethod.GET })
public void loadToken(Model model,HttpServletResponse response,@RequestParam(value = "clientId", required = false) String clientId) {
String token = "";
RequestAttributes ra = RequestContextHolder.getRequestAttributes();
ServletRequestAttributes sra = (ServletRequestAttributes) ra;
HttpServletRequest request = sra.getRequest();
HttpSession session = request.getSession();
if (session.getAttribute("SPRING_SECURITY_CONTEXT") != null) {
SecurityContext securityContext = (SecurityContext)session.getAttribute("SPRING_SECURITY_CONTEXT");
Authentication authentication = securityContext.getAuthentication();
OAuth2AuthenticationDetails OAuth2AuthenticationDetails = (OAuth2AuthenticationDetails) authentication.getDetails();
token = OAuth2AuthenticationDetails.getTokenValue();
}
try {
String url = "http://localhost:9999/rediect?clientId=dev&token="+token;
response.sendRedirect(url);
} catch (IOException e) {
e.printStackTrace();
}
}
服务端应用，单点登录方法，如下：
@RequestMapping("/rediect")
public String rediect(HttpServletResponse responsel, String clientId, String token) {
OAuth2Authentication authentication = tokenStore.readAuthentication(token);
if (authentication == null) {
throw new InvalidTokenException("Invalid access token: " + token);
}
OAuth2Request request = authentication.getOAuth2Request();
Map map = new HashMap();
map.put("code", request.getRequestParameters().get("code"));
map.put("grant_type", request.getRequestParameters().get("grant_type"));
map.put("response_type", request.getRequestParameters().get("response_type"));
//TODO 需要查询一下要跳转的Client_id配置的回调地址
map.put("redirect_uri", "http://127.0.0.1:8888");
map.put("client_id", clientId);
map.put("state", request.getRequestParameters().get("state"));
request = new OAuth2Request(map, clientId, request.getAuthorities(), request.isApproved(), request.getScope(),
request.getResourceIds(), map.get("redirect_uri").toString(), request.getResponseTypes(),request.getExtensions()); // 模拟用户登录
Authentication t = tokenStore.readAuthentication(token);
OAuth2Authentication auth = new OAuth2Authentication(request, t);
OAuth2AccessToken new_token = defaultTokenServices.createAccessToken(auth);
return "redirect:/user_info?access_token=" + new_token.getValue();
}
@RequestMapping({ "/user_info" })
public void user(String access_token,HttpServletResponse response) {
OAuth2Authentication auth=tokenStore.readAuthentication(access_token);
OAuth2Request request=auth.getOAuth2Request();
Map<String, String> map = new LinkedHashMap<>();
map.put("loginName", auth.getUserAuthentication().getName());
map.put("password", auth.getUserAuthentication().getName());
map.put("id", auth.getUserAuthentication().getName());
try {
response.sendRedirect(request.getRedirectUri()+"?name="+auth.getUserAuthentication().getName());
} catch (IOException e) {
e.printStackTrace();
}
}
个人总结
Oauth2的设计相对复杂，需要深入学习多看源码才能了解内部的一些规则，如数据token的存储是用的实体序列化后内容，需要反序列才能在项目是使用，也许是为了安全，但在学习过程需要提前掌握，还有在token的过期时间不能为0，通常来讲过期时间为0代表长期有效，但在Oauth2中则报错，这些坑需要一点点探索。
通过集成Spring Security和Oauth2较大的提供的开发的效率，也提供的代码的灵活性和可用性。但封装的核心类需要大家都了解一下，通读下代码，以便在项目中可随时获取需要的参数。
示例代码
以下是个人的一套代码，供参考。
基于Spring Cloud的微服务框架集成Oauth2的代码示例
Oauth2数据结构，如下：
