Spring Cloud Security 为构建安全的SpringBoot应用提供了一系列解决方案,结合Oauth2还能够实现更多功能,好比使用JWT令牌存储信息,刷新令牌功能,本文将对其结合JWT使用进行详细介绍。java
JWT是JSON WEB TOKEN的缩写,它是基于 RFC 7519 标准定义的一种能够安全传输的的JSON对象,因为使用了数字签名,因此是可信任和安全的。
{ "alg": "HS256", "typ": "JWT" }
{ "exp": 1572682831, "user_name": "macro", "authorities": [ "admin" ], "jti": "c1a0645a-28b5-4468-b4c7-9623131853af", "client_id": "admin", "scope": [ "all" ] }

该模块只是对oauth2-server模块的扩展,直接复制过来扩展下下便可。git
在上一节中咱们都是把令牌存储在内存中的,这样若是部署多个服务,就会致使没法使用令牌的问题。
Spring Cloud Security中有两种存储令牌的方式可用于解决该问题,一种是使用Redis来存储,另外一种是使用JWT来存储。
<dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-data-redis</artifactId> </dependency>
spring: redis: #redis相关配置 password: 123456 #有密码时设置
/** * 使用redis存储token的配置 * Created by macro on 2019/10/8. */ @Configuration public class RedisTokenStoreConfig { @Autowired private RedisConnectionFactory redisConnectionFactory; @Bean public TokenStore redisTokenStore (){ return new RedisTokenStore(redisConnectionFactory); } }
/** * 认证服务器配置 * Created by macro on 2019/9/30. */ @Configuration @EnableAuthorizationServer public class AuthorizationServerConfig extends AuthorizationServerConfigurerAdapter { @Autowired private PasswordEncoder passwordEncoder; @Autowired private AuthenticationManager authenticationManager; @Autowired private UserService userService; @Autowired @Qualifier("redisTokenStore") private TokenStore tokenStore; /** * 使用密码模式须要配置 */ @Override public void configure(AuthorizationServerEndpointsConfigurer endpoints) { endpoints.authenticationManager(authenticationManager) .userDetailsService(userService) .tokenStore(tokenStore);//配置令牌存储策略 } //省略代码... }
/** * 使用Jwt存储token的配置 * Created by macro on 2019/10/8. */ @Configuration public class JwtTokenStoreConfig { @Bean public TokenStore jwtTokenStore() { return new JwtTokenStore(jwtAccessTokenConverter()); } @Bean public JwtAccessTokenConverter jwtAccessTokenConverter() { JwtAccessTokenConverter accessTokenConverter = new JwtAccessTokenConverter(); accessTokenConverter.setSigningKey("test_key");//配置JWT使用的秘钥 return accessTokenConverter; } }
/** * 认证服务器配置 * Created by macro on 2019/9/30. */ @Configuration @EnableAuthorizationServer public class AuthorizationServerConfig extends AuthorizationServerConfigurerAdapter { @Autowired private PasswordEncoder passwordEncoder; @Autowired private AuthenticationManager authenticationManager; @Autowired private UserService userService; @Autowired @Qualifier("jwtTokenStore") private TokenStore tokenStore; @Autowired private JwtAccessTokenConverter jwtAccessTokenConverter; @Autowired private JwtTokenEnhancer jwtTokenEnhancer; /** * 使用密码模式须要配置 */ @Override public void configure(AuthorizationServerEndpointsConfigurer endpoints) { endpoints.authenticationManager(authenticationManager) .userDetailsService(userService) .tokenStore(tokenStore) //配置令牌存储策略 .accessTokenConverter(jwtAccessTokenConverter); } //省略代码... }
{ "exp": 1572682831, "user_name": "macro", "authorities": [ "admin" ], "jti": "c1a0645a-28b5-4468-b4c7-9623131853af", "client_id": "admin", "scope": [ "all" ] }
有时候咱们须要扩展JWT中存储的内容,这里咱们在JWT中扩展一个key为enhance
,value为enhance info
的数据。
/** * Jwt内容加强器 * Created by macro on 2019/10/8. */ public class JwtTokenEnhancer implements TokenEnhancer { @Override public OAuth2AccessToken enhance(OAuth2AccessToken accessToken, OAuth2Authentication authentication) { Map<String, Object> info = new HashMap<>(); info.put("enhance", "enhance info"); ((DefaultOAuth2AccessToken) accessToken).setAdditionalInformation(info); return accessToken; } }
/** * 使用Jwt存储token的配置 * Created by macro on 2019/10/8. */ @Configuration public class JwtTokenStoreConfig { //省略代码... @Bean public JwtTokenEnhancer jwtTokenEnhancer() { return new JwtTokenEnhancer(); } }
/** * 认证服务器配置 * Created by macro on 2019/9/30. */ @Configuration @EnableAuthorizationServer public class AuthorizationServerConfig extends AuthorizationServerConfigurerAdapter { @Autowired private PasswordEncoder passwordEncoder; @Autowired private AuthenticationManager authenticationManager; @Autowired private UserService userService; @Autowired @Qualifier("jwtTokenStore") private TokenStore tokenStore; @Autowired private JwtAccessTokenConverter jwtAccessTokenConverter; @Autowired private JwtTokenEnhancer jwtTokenEnhancer; /** * 使用密码模式须要配置 */ @Override public void configure(AuthorizationServerEndpointsConfigurer endpoints) { TokenEnhancerChain enhancerChain = new TokenEnhancerChain(); List<TokenEnhancer> delegates = new ArrayList<>(); delegates.add(jwtTokenEnhancer); //配置JWT的内容加强器 delegates.add(jwtAccessTokenConverter); enhancerChain.setTokenEnhancers(delegates); endpoints.authenticationManager(authenticationManager) .userDetailsService(userService) .tokenStore(tokenStore) //配置令牌存储策略 .accessTokenConverter(jwtAccessTokenConverter) .tokenEnhancer(enhancerChain); } //省略代码... }
{ "user_name": "macro", "scope": [ "all" ], "exp": 1572683821, "authorities": [ "admin" ], "jti": "1ed1b0d8-f4ea-45a7-8375-211001a51a9e", "client_id": "admin", "enhance": "enhance info" }
若是咱们须要获取JWT中的信息,可使用一个叫jjwt的工具包。
<dependency> <groupId>io.jsonwebtoken</groupId> <artifactId>jjwt</artifactId> <version>0.9.0</version> </dependency>
/** * Created by macro on 2019/9/30. */ @RestController @RequestMapping("/user") public class UserController { @GetMapping("/getCurrentUser") public Object getCurrentUser(Authentication authentication, HttpServletRequest request) { String header = request.getHeader("Authorization"); String token = StrUtil.subAfter(header, "bearer ", false); return Jwts.parser() .setSigningKey("test_key".getBytes(StandardCharsets.UTF_8)) .parseClaimsJws(token) .getBody(); } }
Authorization
头中,访问以下地址获取信息:http://localhost:9401/user/getCurrentUser在Spring Cloud Security 中使用oauth2时,若是令牌失效了,可使用刷新令牌经过refresh_token的受权模式再次获取access_token。
/** * 认证服务器配置 * Created by macro on 2019/9/30. */ @Configuration @EnableAuthorizationServer public class AuthorizationServerConfig extends AuthorizationServerConfigurerAdapter { @Override public void configure(ClientDetailsServiceConfigurer clients) throws Exception { clients.inMemory() .withClient("admin") .secret(passwordEncoder.encode("admin123456")) .accessTokenValiditySeconds(3600) .refreshTokenValiditySeconds(864000) .redirectUris("http://www.baidu.com") .autoApprove(true) //自动受权配置 .scopes("all") .authorizedGrantTypes("authorization_code","password","refresh_token"); //添加受权模式 } }
