一,為什么oauth2要整合jwt?
1,OAuth2的token技術有一個最大的問題是不攜帶用戶信息,所以資源服務器不能進行本地驗證,
以致每次對於資源的訪問,資源服務器都需要向認證服務器的token存儲發起請求,
一是驗證token的有效性,二是獲取token對應的用戶信息。
有大量的請求時會導致處理效率降低,
而且認證服務器作為一個中心節點,
對於SLA和處理性能等均有很高的要求
對於分布式架構都是可能引發問題的隱患
2,jwt技術的兩個優勢:
token的簽名驗證可以直接在資源服務器本地完成,不需要再次連接認證服務器
jwt的payload部分可以保存用戶相關信息,這樣直接有了token和用戶信息的綁定
3,spring security oauth2生成token時的輸出默認格式不能直接修改,
演示例子中通過增加一個controller實現了輸出的格式化

3,數據庫:

建表sql:
CREATE TABLE `sys_user` ( `userId` int(11) NOT NULL AUTO_INCREMENT COMMENT 'id', `userName` varchar(100) NOT NULL DEFAULT '' COMMENT '用戶名', `password` varchar(100) NOT NULL DEFAULT '' COMMENT '密碼', `nickName` varchar(100) CHARACTER SET utf8mb4 COLLATE utf8mb4_0900_ai_ci NOT NULL DEFAULT '' COMMENT '昵稱', PRIMARY KEY (`userId`), UNIQUE KEY `userName` (`userName`) ) ENGINE=InnoDB AUTO_INCREMENT=0 DEFAULT CHARSET=utf8mb4 COLLATE=utf8mb4_0900_ai_ci COMMENT='用戶表'
INSERT INTO `sys_user` (`userId`, `userName`, `password`, `nickName`) VALUES (1, 'lhd', '$2a$10$yGcOz3ekNI6Ya67tqQueS.raxyTOedGsv5jh2BwtRrI5/K9QEIPGq', '老劉'), (2, 'admin', '$2a$10$yGcOz3ekNI6Ya67tqQueS.raxyTOedGsv5jh2BwtRrI5/K9QEIPGq', '管理員'), (3, 'merchant', '$2a$10$yGcOz3ekNI6Ya67tqQueS.raxyTOedGsv5jh2BwtRrI5/K9QEIPGq', '商戶老張');
說明:3個密碼都是111111,僅供演示使用
CREATE TABLE `sys_user_role` ( `urId` int(11) NOT NULL AUTO_INCREMENT COMMENT 'id', `userId` int(11) NOT NULL DEFAULT '0' COMMENT '用戶id', `roleName` varchar(20) CHARACTER SET utf8mb4 COLLATE utf8mb4_0900_ai_ci NOT NULL DEFAULT '' COMMENT '角色id', PRIMARY KEY (`urId`), UNIQUE KEY `userId` (`userId`,`roleName`) ) ENGINE=InnoDB AUTO_INCREMENT=0 DEFAULT CHARSET=utf8mb4 COLLATE=utf8mb4_0900_ai_ci COMMENT='用戶角色關聯表'
INSERT INTO `sys_user_role` (`urId`, `userId`, `roleName`) VALUES (1, 2, 'ADMIN'), (2, 3, 'MERCHANT');
四,java代碼說明
1,WebSecurityConfig.java
@Configuration @EnableWebSecurity @EnableGlobalMethodSecurity(prePostEnabled = true) public class WebSecurityConfig extends WebSecurityConfigurerAdapter { private final static BCryptPasswordEncoder ENCODER = new BCryptPasswordEncoder(); @Resource private SecUserDetailService secUserDetailService; //用戶信息類,用來得到UserDetails @Bean @Override protected AuthenticationManager authenticationManager() throws Exception { return super.authenticationManager(); } @Bean @Override protected UserDetailsService userDetailsService() { return super.userDetailsService(); } @Bean PasswordEncoder passwordEncoder() { return new BCryptPasswordEncoder(); } @Override protected void configure(HttpSecurity http) throws Exception { http.csrf().disable(); http.antMatcher("/oauth/**") .authorizeRequests() .antMatchers("/oauth/**").permitAll() .and().csrf().disable(); } @Resource public void configureGlobal(AuthenticationManagerBuilder auth) throws Exception { auth.userDetailsService(secUserDetailService).passwordEncoder(new PasswordEncoder() { @Override public String encode(CharSequence charSequence) { return ENCODER.encode(charSequence); } //密碼匹配,看輸入的密碼經過加密與數據庫中存放的是否一樣 @Override public boolean matches(CharSequence charSequence, String s) { return ENCODER.matches(charSequence,s); } }); } }
2,AuthorizationServerConfig.java
@Configuration @EnableAuthorizationServer public class AuthorizationServerConfig extends AuthorizationServerConfigurerAdapter { @Resource AuthenticationManager authenticationManager; @Resource UserDetailsService userDetailsService; @Resource TokenStore jwtTokenStore; @Resource JwtAccessTokenConverter jwtAccessTokenConverter; @Override public void configure(ClientDetailsServiceConfigurer clients) throws Exception { String clientId = "client_id"; String clientSecret = "123"; clients.inMemory() //這個好比賬號 .withClient(clientId) //授權同意的類型 .authorizedGrantTypes("password", "refresh_token") //有效時間 .accessTokenValiditySeconds(1800) .refreshTokenValiditySeconds(60 * 60 * 2) .resourceIds("rid") //作用域,范圍 .scopes("all") //密碼 .secret(new BCryptPasswordEncoder().encode(clientSecret)); } @Override public void configure(AuthorizationServerEndpointsConfigurer endpoints) throws Exception { endpoints.tokenStore(jwtTokenStore) .authenticationManager(authenticationManager) .userDetailsService(userDetailsService) .accessTokenConverter(jwtAccessTokenConverter); } @Override public void configure(AuthorizationServerSecurityConfigurer security) throws Exception { //允許客戶端表單身份驗證 security.allowFormAuthenticationForClients(); } }
授權服務器的配置
3,ResourceServerConfig.java
@Configuration @EnableResourceServer public class ResourceServerConfig extends ResourceServerConfigurerAdapter { private static final String RESOURCE_ID = "rid"; @Resource private RestAuthenticationEntryPoint restAuthenticationEntryPoint; @Resource private RestAccessDeniedHandler restAccessDeniedHandler; @Override public void configure(ResourceServerSecurityConfigurer resources) { resources.resourceId(RESOURCE_ID).stateless(false) .authenticationEntryPoint(restAuthenticationEntryPoint); } @Override public void configure(HttpSecurity http) throws Exception { http.authorizeRequests() .antMatchers("/admin/**").hasAnyRole("admin","ADMIN"); http. anonymous().disable() .authorizeRequests() .antMatchers("/users/**").access("hasRole('ADMIN')") .and().exceptionHandling().accessDeniedHandler(new OAuth2AccessDeniedHandler()); //http.exceptionHandling().authenticationEntryPoint(restAuthenticationEntryPoint); http.exceptionHandling().accessDeniedHandler(restAccessDeniedHandler); } }
資源服務器的配置
4,RestAccessDeniedHandler.java
@Component("restAccessDeniedHandler")
public class RestAccessDeniedHandler implements AccessDeniedHandler {
//處理權限不足的情況:403,對應:access_denied
@Override
public void handle(HttpServletRequest request, HttpServletResponse response,
AccessDeniedException accessDeniedException)
throws IOException, ServletException {
System.out.println("-------RestAccessDeniedHandler");
ServletUtil.printRestResult(RestResult.error(403,"權限不夠訪問當前資源,被拒絕"));
}
}
遇到access deny情況的處理
5,RestAuthenticationEntryPoint.java
@Component("restAuthenticationEntryPoint")
public class RestAuthenticationEntryPoint implements AuthenticationEntryPoint {
//返回未得到授權時的報錯:對應:invalid_token
@Override
public void commence(
HttpServletRequest request,
HttpServletResponse response,
AuthenticationException authException) throws IOException {
//System.out.println("commence");
ServletUtil.printRestResult(RestResult.error(401,"未得到授權"));
}
}
匿名用戶無權訪問時的處理
6,JwtTokenConfig.java
@Configuration public class JwtTokenConfig { @Bean public TokenStore jwtTokenStore(){ return new JwtTokenStore(jwtAccessTokenConverter()); } //使用Jwt來作為token的生成 @Bean public JwtAccessTokenConverter jwtAccessTokenConverter(){ JwtAccessTokenConverter accessTokenConverter = new JwtAccessTokenConverter(); accessTokenConverter.setSigningKey("internet_plus"); return accessTokenConverter; } @Bean public TokenEnhancer jwtTokenEnhancer(){ return new JwtTokenEnhancer (); } }
配置jwttoken,指定了signkey
7,JwtTokenEnhancer.java
public class JwtTokenEnhancer implements TokenEnhancer { @Override public OAuth2AccessToken enhance(OAuth2AccessToken accessToken, OAuth2Authentication authentication) { Map<String,Object> info = new HashMap<>(); info.put("provider","haolarn"); //設置附加信息 ((DefaultOAuth2AccessToken)accessToken).setAdditionalInformation(info); return null; } }
返回token信息中的附加信息
8,OauthController.java
@RestController @RequestMapping("/oauth") public class OauthController { @Autowired private TokenEndpoint tokenEndpoint; //自定義返回信息添加基本信息 @PostMapping("/token") public RestResult postAccessTokenWithUserInfo(Principal principal, @RequestParam Map<String, String> parameters) throws HttpRequestMethodNotSupportedException { OAuth2AccessToken accessToken = tokenEndpoint.postAccessToken(principal, parameters).getBody(); Map<String, Object> data = new LinkedHashMap(); data.put("accessToken", accessToken.getValue()); data.put("token_type", accessToken.getTokenType()); data.put("refreshToken", accessToken.getRefreshToken().getValue()); data.put("scope", accessToken.getScope()); data.put("expires_in", accessToken.getExpiresIn()); data.put("jti", accessToken.getAdditionalInformation().get("jti")); return RestResult.success(data); } }
格式化生成token時的返回json信息
9,其他非關鍵代碼可以訪問github查看,不再一一貼出
五,測試效果
1,得到基於jwt的token
訪問:http://127.0.0.1:8080/oauth/token

返回結果:

2,用得到的access_token訪問admin/hello:查看當前用戶和role:
http://127.0.0.1:8080/admin/hello
返回:

3,換一個無權限的賬號登錄:

訪問admin/hello時會提示無權限
