Spring Security OAuth2之自定义令牌配置与使用JWT令牌替换默认令牌

飞熊 • • 后端漫谈 • 阅读 177

生活中，最使人疲惫的往往不是道路的遥远，而是心中的郁闷;最使人痛苦的往往不是生活的不幸，而是希望的破灭;最使人颓废的往往不是前途的坎坷，而是自信的丧失;最使人绝望的往往不是挫折的打击，而是心灵的死亡。所以我们要有自己的梦想，让梦想的星光指引着我们走出落漠，走出惆怅，带着我们走进自己的理想。

导读：本篇文章讲解 Spring Security OAuth2之自定义令牌配置与使用JWT令牌替换默认令牌，希望对大家有帮助，欢迎收藏，转发！站点地址：www.bmabk.com，来源：原文

Spring Security OAuth2之自定义令牌配置与使用JWT令牌替换默认令牌

搭建基本的认证与资源服务

添加依赖

            </dependency>
        </dependencies>
    </dependencyManagement>

搭建认证服务

创建MyAuthorizationServerConfig 类并继承WebSecurityConfigurerAdapter ，同时实用@EnableAuthorizationServer注解申明这里一个认证服务配置类

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.security.config.annotation.web.configuration.WebSecurityConfigurerAdapter;
import org.springframework.security.crypto.bcrypt.BCryptPasswordEncoder;
import org.springframework.security.crypto.password.PasswordEncoder;
import org.springframework.security.oauth2.config.annotation.web.configuration.EnableAuthorizationServer;

@Configuration
@EnableAuthorizationServer
public class MyAuthorizationServerConfig extends WebSecurityConfigurerAdapter {

    @Bean
    public PasswordEncoder passwordEncoder() {
        return new BCryptPasswordEncoder();
    }
}

自定义MyUserDetailService，实现账号登录相关校验逻辑，预设密码必须为123456，且拥有admin权限，使用任意账号即可登录。

@Service
public class MyUserDetailService implements UserDetailsService {

    @Autowired
    private PasswordEncoder passwordEncoder;

    @Override
    public UserDetails loadUserByUsername(String username) throws UsernameNotFoundException {
        return new User(username, this.passwordEncoder.encode("123456"),
                true, true, true,
                true, AuthorityUtils.commaSeparatedStringToAuthorityList("admin"));
    }
}

配置客户端，若不配置指定client-id和client-secret，则会随机分配

security:
  oauth2:
    client:
      client-id: web
      client-secret: 123456789
      registered-redirect-uri: http://127.0.0.1:8888/test

搭建资源服务

定义资源一个资源类，用于访问测试。

import org.springframework.security.core.Authentication;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RestController;

@RestController
public class TestController {

    @GetMapping("index")
    public Object index(Authentication authentication) {
        return authentication;
    }
}

创建MyResourceServerConfig 类继承ResourceServerConfigurerAdapter 类，同时使用@EnableResourceServer注解申明这是一个资源服务配置类

import org.springframework.context.annotation.Configuration;
import org.springframework.security.oauth2.config.annotation.web.configuration.EnableResourceServer;
import org.springframework.security.oauth2.config.annotation.web.configuration.ResourceServerConfigurerAdapter;

@Configuration
@EnableResourceServer
public class MyResourceServerConfig extends ResourceServerConfigurerAdapter {

}

配置指定资源服务器地址

security:
  oauth2:
    resource:
      user-info-uri: http://127.0.0.1:8888

自定义令牌配置

配置认证服务器

创建MySecurityConfig配置类

@Configuration
public class MySecurityConfig extends WebSecurityConfigurerAdapter {

    @Bean(name = BeanIds.AUTHENTICATION_MANAGER)
    @Override
    public AuthenticationManager authenticationManagerBean() throws Exception {
        return super.authenticationManagerBean();
    }
}

创建AuthorizationServerConfig类继承AuthorizationServerConfigurerAdapter适配器，同时重写configure()相关的2个方法

@Configuration
@EnableAuthorizationServer
public class MyAuthorizationServerConfig extends AuthorizationServerConfigurerAdapter {

    @Bean
    public PasswordEncoder passwordEncoder() {
        return new BCryptPasswordEncoder();
    }

    @Autowired
    private AuthenticationManager authenticationManager;

    @Autowired
    private MyUserDetailService userDetailService;

    /**
     * 指定AuthenticationManage和UserDetailService
     */
    @Override
    public void configure(AuthorizationServerEndpointsConfigurer endpoints) {
        endpoints.authenticationManager(authenticationManager)
                .userDetailsService(userDetailService);
    }

    /**
     * 创建两个客户端：web app,不同客户端获取不同的令牌
     * web客户端令牌有效时间为3600秒。app客户端令牌有效时间为7200秒。
     * web客户端的的refresh_token有效时间为86400*7秒，在规定时间内可通过refresh_token换取新的令牌
     * web客户端获取令牌时，scope只能指定为all、a、b中的某个值，否则将获取失败
     * web客户端只能通过密码模式(password)来获取令牌，而app客户端无限制
     */
    @Override
    public void configure(ClientDetailsServiceConfigurer clients) throws Exception {
        clients.inMemory()
                .withClient("web")
                .secret(new BCryptPasswordEncoder().encode("123456789"))
                .accessTokenValiditySeconds(3600)
                .refreshTokenValiditySeconds(86400 * 7)
                .scopes("all", "a", "b")
                .authorizedGrantTypes("password")
                .and()
                .withClient("app")
                .secret(new BCryptPasswordEncoder().encode("123456789"))
                .accessTokenValiditySeconds(7200);
    }
}

在新版本的spring-cloud-starter-oauth2指定client_secret需要进行加密处理，否则将如此如下错误：
1.请求出现异常

{
	"error": "unauthorized",
	"error_description": "Full authentication is required to access this resource"
}

2.控制台输出告警

2022-10-22 13:15:48.489  WARN 22500 --- [qtp645715998-37] o.s.s.c.bcrypt.BCryptPasswordEncoder     : Encoded password does not look like BCrypt

执行测试

	"token_type": "bearer",
	"expires_in": 7200,
	"scope": "b"
}

令牌存储策略

令牌默认是存储在内存中的，可以将它保存到第三方存储中，通常使用Redis。

添加依赖

   <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-data-redis</artifactId>
        </dependency>

创建令牌通存储策略配置

@Configuration
public class TokenStoreConfig {

    @Autowired
    private RedisConnectionFactory redisConnectionFactory;

    @Bean
    public TokenStore redisTokenStore (){
        return new RedisTokenStore(redisConnectionFactory);
    }
}

配置认证服务器

在认证服务器指定要求使用该令牌存储策略

@Configuration
@EnableAuthorizationServer
public class MyAuthorizationServerConfig extends AuthorizationServerConfigurerAdapter {

    @Bean
    public PasswordEncoder passwordEncoder() {
        return new BCryptPasswordEncoder();
    }

    @Autowired
    private AuthenticationManager authenticationManager;

    @Autowired
    private MyUserDetailService userDetailService;

    @Autowired
    private TokenStore redisTokenStore;

    /**
     * 指定AuthenticationManage和UserDetailService
     */
    @Override
    public void configure(AuthorizationServerEndpointsConfigurer endpoints) {
        endpoints.authenticationManager(authenticationManager)
                .tokenStore(redisTokenStore)
                .userDetailsService(userDetailService);
    }
    
	/**
     * 创建两个客户端：web app,不同客户端获取不同的令牌
     */
    @Override
    public void configure(ClientDetailsServiceConfigurer clients) throws Exception {
        clients.inMemory()
                .withClient("web")
                .secret(new BCryptPasswordEncoder().encode("123456789"))
                .accessTokenValiditySeconds(3600)
                .refreshTokenValiditySeconds(86400 * 7)
                .scopes("all", "a", "b")
                .authorizedGrantTypes("password")
                .and()
                .withClient("app")
                .secret(new BCryptPasswordEncoder().encode("123456789"))
                .accessTokenValiditySeconds(7200);
    }
}

执行测试

重启项目，获取令牌，查看Redis中是否存储了令牌信息

Redis:0>keys *
1) "client_id_to_access:web"
2) "access:d816292d-9487-4def-b680-897025382778"
3) "auth:d816292d-9487-4def-b680-897025382778"
4) "auth_to_access:81b695a6db737a1bed92d38ec9beb09d"
5) "uname_to_access:web:test_user"

JWT替换默认令牌

默认令牌使用UUID生成，使用JWT替换默认的令牌，只需要指定TokenStore为JwtTokenStore即可。

创建JWTokenConfig配置类

@Configuration
public class JWTokenConfig {

	/**
     * 注意：若定义了redisTokenStore，则此处需要使用@Primary申明，默认优先使用jwtTokenStore令牌存储策略
     * @return
     */
    @Bean
    @Primary
    public TokenStore jwtTokenStore() {
        return new JwtTokenStore(jwtAccessTokenConverter());
    }

    @Bean
    public JwtAccessTokenConverter jwtAccessTokenConverter() {
        JwtAccessTokenConverter accessTokenConverter = new JwtAccessTokenConverter();
        // 设置签名密钥
        accessTokenConverter.setSigningKey("signingKey");
        return accessTokenConverter;
    }
}

配置认证服务器

在认证服务器中指定使用JWTokenConfig

@Configuration
@EnableAuthorizationServer
public class MyAuthorizationServerConfig extends AuthorizationServerConfigurerAdapter {

    @Bean
    public PasswordEncoder passwordEncoder() {
        return new BCryptPasswordEncoder();
    }

    @Autowired
    private AuthenticationManager authenticationManager;

    @Autowired
    private MyUserDetailService userDetailService;
    
    @Autowired
    private TokenStore jwtTokenStore;
    
    @Autowired
    private JwtAccessTokenConverter jwtAccessTokenConverter;


    /**
     * 指定AuthenticationManage和UserDetailService
     */
    @Override
    public void configure(AuthorizationServerEndpointsConfigurer endpoints) {
        endpoints.authenticationManager(authenticationManager)
                .tokenStore(jwtTokenStore)
                .accessTokenConverter(jwtAccessTokenConverter)
                .userDetailsService(userDetailService);
    }

    /**
     * 创建两个客户端：web app,不同客户端获取不同的令牌
     */
    @Override
    public void configure(ClientDetailsServiceConfigurer clients) throws Exception {
        clients.inMemory()
                .withClient("web")
                .secret(new BCryptPasswordEncoder().encode("123456789"))
                .accessTokenValiditySeconds(3600)
                .refreshTokenValiditySeconds(86400 * 7)
                .scopes("all", "a", "b")
                .authorizedGrantTypes("password")
                .and()
                .withClient("app")
                .secret(new BCryptPasswordEncoder().encode("123456789"))
                .accessTokenValiditySeconds(7200);
    }
}

获取令牌，返回如下格式令牌

{
	"access_token": "eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJleHAiOjE2NjY0NTUyMzIsInVzZXJfbmFtZSI6InRlc3RfdXNlciIsImF1dGhvcml0aWVzIjpbImFkbWluIl0sImp0aSI6ImQ2Y2U1MmNmLWQxNmItNDNiOS1iMjM1LTg3MWNkMzQ0MTljNiIsImNsaWVudF9pZCI6IndlYiIsInNjb3BlIjpbImEiXX0.du3OtENDz8VHjZ3QSWBe491mFDirt_9xmq-06bG1puc",
	"token_type": "bearer",
	"expires_in": 3599,
	"scope": "a",
	"jti": "d6ce52cf-d16b-43b9-b235-871cd34419c6"
}

访问https://jwt.io/，将access_token中的内容复制并解析
在这里插入图片描述

JWT扩展增强

Token解析将得到PAYLOAD，如果想在JWT中添加额外信息，需要实现TokenEnhancer，相当于是一个Token增强器

创建JWTokenEnhancer

创建JWTokenEnhancer类，实现TokenEnhancer接口，重写enhance()方法，添加额外的JWT信息。

public class JWTokenEnhancer implements TokenEnhancer {
    @Override
    public OAuth2AccessToken enhance(OAuth2AccessToken oAuth2AccessToken, OAuth2Authentication oAuth2Authentication) {
        Map<String, Object> info = new HashMap<>();
        info.put("msg", "hello world Jwt");
        DefaultOAuth2AccessToken defaultOAuth2AccessToken = (DefaultOAuth2AccessToken) oAuth2AccessToken;
        defaultOAuth2AccessToken.setAdditionalInformation(info);
        return oAuth2AccessToken;
    }
}

配置JWTokenConfig

在JWTokenConfig类里注册该JWTokenEnhancer对象

@Configuration
public class JWTokenConfig {

    /**
     * 注意：若定义了redisTokenStore，则此处需要使用@Primary申明，默认优先使用jwtTokenStore令牌存储策略
     *
     * @return
     */
    @Bean
    @Primary
    public TokenStore jwtTokenStore() {
        return new JwtTokenStore(jwtAccessTokenConverter());
    }

    @Bean
    public JwtAccessTokenConverter jwtAccessTokenConverter() {
        JwtAccessTokenConverter accessTokenConverter = new JwtAccessTokenConverter();
        // 设置签名密钥
        accessTokenConverter.setSigningKey("signingKey");
        return accessTokenConverter;
    }

    @Bean
    public TokenEnhancer tokenEnhancer() {
        return new JWTokenEnhancer();
    }
}

认证服务器配置JWT增强器

    @Autowired
    private TokenStore jwtTokenStore;
    @Autowired
    private JwtAccessTokenConverter jwtAccessTokenConverter;
    @Autowired
    private TokenEnhancer tokenEnhancer;


    @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)
                .accessTokenConverter(jwtAccessTokenConverter)
                .tokenEnhancer(enhancerChain)
                .userDetailsService(userDetailService);
    }

执行测试

{
	"access_token": "eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJtc2ciOiJoZWxsbyB3b3JsZCBKd3QiLCJ1c2VyX25hbWUiOiJ0ZXN0X3VzZXIiLCJzY29wZSI6WyJhIl0sImV4cCI6MTY2NjQ1NjI0NCwiYXV0aG9yaXRpZXMiOlsiYWRtaW4iXSwianRpIjoiZTA4YmQwNmItYjRhNi00NDFlLWI2YzUtZTdkOWQ3MjViZmFiIiwiY2xpZW50X2lkIjoid2ViIn0.tUsuBH_o6YTyhqhfEAwGrY69ij-HhYs52cTHvYAmzfI",

	"msg": "hello world Jwt",
	"jti": "e08bd06b-b4a6-441e-b6c5-e7d9d725bfab"
}

解析JWT

在Java代码中解析JWT

添加依赖

 <dependency>
            <groupId>io.jsonwebtoken</groupId>
            <artifactId>jjwt</artifactId>
            <version>0.9.1</version>
        </dependency>

解析JWT

解析JWT需要注意：signkey需要和JwtAccessTokenConverter中指定的签名密钥一致

@RestController
public class TestController {

    @GetMapping("index")
    public Object index(Authentication authentication, HttpServletRequest request) {
        System.out.println("authentication = " + authentication.toString());
        String header = request.getHeader("Authorization");
        String token = StringUtils.substringAfter(header, "bearer ");
        // signkey需要和JwtAccessTokenConverter中指定的签名密钥一致
        return Jwts.parser().setSigningKey("signingKey".getBytes(StandardCharsets.UTF_8)).parseClaimsJws(token).getBody();
    }
}

执行测试

先获取令牌

{
	"access_token": "eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJtc2ciOiJoZWxsbyB3b3JsZCBKd3QiLCJ1c2VyX25hbWUiOiJ0ZXN0X3VzZXIiLCJzY29wZSI6WyJhIl0sImV4cCI6MTY2NjQ1Njc0MSwiYXV0aG9yaXRpZXMiOlsiYWRtaW4iXSwianRpIjoiNmE4YzRkMGUtMGZiZS00N2U1LTk2MzItNDAzODYyYTY4MTVlIiwiY2xpZW50X2lkIjoid2ViIn0.KDz0PCe53HBycIocxOoE8fV6OjyPZik4w9NBy3fiWbI",
	"token_type": "bearer",

	"scope": "a",
	"msg": "hello world Jwt",
	"jti": "6a8c4d0e-0fbe-47e5-9632-403862a6815e"
}

在这里插入图片描述

{
	"msg": "hello world Jwt",
	"user_name": "test_user",
	"scope": [
		"a"
	],
	"exp": 1666456741,
	"authorities": [
		"admin"
	],
	"jti": "6a8c4d0e-0fbe-47e5-9632-403862a6815e",
	"client_id": "web"
}

刷新令牌

令牌过期后需要使用refresh_token从系统中换取一个新的可用令牌。

目前，系统是未返回refresh_token，需要在认证服务器自定义配置。

配置认证服务器

只需要指定授权方式处，添加refresh_token，是支持四种标准的OAuth2获取令牌方式。

配置后，web客户端获取令牌时将返回refresh_token，refresh_token有效期为10天，即10天之内可以用它换取新的可用令牌。

    @Override
    public void configure(ClientDetailsServiceConfigurer clients) throws Exception {
        clients.inMemory()
                .withClient("web")
                .secret(new BCryptPasswordEncoder().encode("123456789"))
                .accessTokenValiditySeconds(3600)
                .refreshTokenValiditySeconds(86400 * 7)
                .scopes("all", "a", "b")
                .authorizedGrantTypes("password","refresh_token")
                .and()
                .withClient("app")
                .secret(new BCryptPasswordEncoder().encode("123456789"))
                .accessTokenValiditySeconds(7200);
    }

执行测试

重启项目，获取令牌
