SpringBoot 整合 spring security oa

废话不说直接进入主题（假设您已对spring security、oauth2、jwt技术的了解，不懂的自行搜索了解）

依赖版本

• springboot 2.1.5.RELEASE
• spring-security-oauth2 2.3.5.RELEASE
• jjwt 0.9.1

新增JWTokenConfig

@Configuration
public class JWTokenConfig {

    @Bean
    public TokenStore jwtTokenStore() {
        return new JwtTokenStore(jwtAccessTokenConverter());
    }

    @Bean
    public JwtAccessTokenConverter jwtAccessTokenConverter() {
        JwtAccessTokenConverter accessTokenConverter = new JwtAccessTokenConverter();
        accessTokenConverter.setSigningKey("entfrm"); //对称加密key
        return accessTokenConverter;
    }

    @Bean
    public TokenEnhancer tokenEnhancer() {
        return new JWTTokenEnhancer(); // token增强
    }
}

JwtAccessTokenConverter：TokenEnhancer的子类，帮助程序在JWT编码的令牌值和OAuth身份验证信息之间进行转换。
此处定义token 签名的方式，采用对称加密方式。

增加JwtTokenEnhancer类

public class JWTTokenEnhancer implements TokenEnhancer {

    @Override
    public OAuth2AccessToken enhance(OAuth2AccessToken oAuth2AccessToken, OAuth2Authentication oAuth2Authentication) {
        Map<String, Object> info = new HashMap<>();
        info.put("license", "entfrm");
        ((DefaultOAuth2AccessToken) oAuth2AccessToken).setAdditionalInformation(info);
        //设置token的过期时间120分钟
        Calendar nowTime = Calendar.getInstance();
        nowTime.add(Calendar.MINUTE, 120);
        ((DefaultOAuth2AccessToken) oAuth2AccessToken).setExpiration(nowTime.getTime());
        return oAuth2AccessToken;
    }
}

重写TokenEnhancer的enhance方法，根据个人需求实现关键字段注入到 JWT 中，方便资源服务器使用。在此处也可以定义token过期时间。

新增AuthorizationServerConfig类，继承AuthorizationServerConfigurerAdapter

@Configuration
@AllArgsConstructor
@EnableAuthorizationServer
public class AuthorizationServerConfig extends AuthorizationServerConfigurerAdapter {

    private final AuthenticationManager authenticationManager;
    private final EntfrmUserDetailService userDetailService;
    private final TokenStore jwtTokenStore;
    private final JwtAccessTokenConverter jwtAccessTokenConverter;
    private final TokenEnhancer tokenEnhancer;
    private final DataSource dataSource;

    @Override
    public void configure(AuthorizationServerEndpointsConfigurer endpoints) {
        TokenEnhancerChain enhancerChain = new TokenEnhancerChain();
        List<TokenEnhancer> enhancers = new ArrayList<>();
        enhancers.add(tokenEnhancer);
        enhancers.add(jwtAccessTokenConverter);
        enhancerChain.setTokenEnhancers(enhancers);

        endpoints.authenticationManager(authenticationManager)
                .tokenStore(jwtTokenStore)
                .tokenEnhancer(enhancerChain)
                .accessTokenConverter(jwtAccessTokenConverter)
                .userDetailsService(userDetailService)
                .allowedTokenEndpointRequestMethods(HttpMethod.GET, HttpMethod.POST);//允许 GET、POST 请求获取 token，即访问端点：oauth/token

        endpoints.reuseRefreshTokens(true);//oauth2登录异常处理
        endpoints.exceptionTranslator(new EntfrmWebResponseExceptionTranslator());//oauth2登录异常处理
    }

    @Override
    public void configure(AuthorizationServerSecurityConfigurer oauthServer) {
        oauthServer
                .checkTokenAccess("isAuthenticated()")
                .allowFormAuthenticationForClients();//允许表单认证
    }

    @Override
    public void configure(ClientDetailsServiceConfigurer clients) throws Exception {
        clients.withClientDetails(clientDetails());
    }

    @Bean
    public ClientDetailsService clientDetails() {
        return new JdbcClientDetailsService(dataSource);//客户端配置 使用jdbc数据库存储
    }
}

endpoints的tokenEnhancer方法需要我们提供一个token增强器链对象TokenEnhancerChain，所以我们需要在链中加入我们重写的TokenEnhancer和jwtAccessTokenConverter，然后放入endpoints。同时我们将客户端配置放到了jdbc数据库中，方便多种客户端的扩展，这儿需要在数据库中创建一张表oauth_client_details，表sql脚本如下：

CREATE TABLE `oauth_client_details`  (
  `client_id` varchar(48) CHARACTER SET utf8 COLLATE utf8_general_ci NOT NULL,
  `resource_ids` varchar(256) CHARACTER SET utf8 COLLATE utf8_general_ci NULL DEFAULT NULL,
  `client_secret` varchar(256) CHARACTER SET utf8 COLLATE utf8_general_ci NULL DEFAULT NULL,
  `scope` varchar(256) CHARACTER SET utf8 COLLATE utf8_general_ci NULL DEFAULT NULL,
  `authorized_grant_types` varchar(256) CHARACTER SET utf8 COLLATE utf8_general_ci NULL DEFAULT NULL,
  `web_server_redirect_uri` varchar(256) CHARACTER SET utf8 COLLATE utf8_general_ci NULL DEFAULT NULL,
  `authorities` varchar(256) CHARACTER SET utf8 COLLATE utf8_general_ci NULL DEFAULT NULL,
  `access_token_validity` int(11) NULL DEFAULT NULL,
  `refresh_token_validity` int(11) NULL DEFAULT NULL,
  `additional_information` varchar(4096) CHARACTER SET utf8 COLLATE utf8_general_ci NULL DEFAULT NULL,
  `autoapprove` varchar(256) CHARACTER SET utf8 COLLATE utf8_general_ci NULL DEFAULT NULL,
  PRIMARY KEY (`client_id`) USING BTREE
) ENGINE = InnoDB CHARACTER SET = utf8 COLLATE = utf8_general_ci ROW_FORMAT = Dynamic;

以上就是OAuth 授权服务器配置。

启动项目 查看效果

token获取 token解析

从图中我们可以看到返回的token中携带了我们加入的扩展信息license，以及授权信息。
