Spring Security Oauth2整合JWT

Spring Security Oauth2 整合JWT

整合JWT

我们拿之前Spring Security Oauth2的完整代码进行修改

添加配置文件JwtTokenStoreConfig.java

package com.yjxxt.springsecurityoauth2demo.config;

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.security.oauth2.provider.token.TokenStore;
import org.springframework.security.oauth2.provider.token.store.JwtAccessTokenConverter;
import org.springframework.security.oauth2.provider.token.store.JwtTokenStore;

/**
 * 使用Jwt存储token的配置
 * @author ylc
 * @since 1.0.0
 */
@Configuration
public class JwtTokenStoreConfig {

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

   @Bean
   public JwtAccessTokenConverter jwtAccessTokenConverter(){
      JwtAccessTokenConverter accessTokenConverter = new JwtAccessTokenConverter();
      //配置JWT使用的秘钥
      accessTokenConverter.setSigningKey("test_key");
      return accessTokenConverter;
   }
}

在认证服务器配置中指定令牌的存储策略为JWT

package com.yjxxt.springsecurityoauth2demo.config;

import com.yjxxt.springsecurityoauth2demo.service.UserService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.annotation.Qualifier;
import org.springframework.context.annotation.Configuration;
import org.springframework.security.authentication.AuthenticationManager;
import org.springframework.security.crypto.password.PasswordEncoder;
import org.springframework.security.oauth2.config.annotation.configurers.ClientDetailsServiceConfigurer;
import org.springframework.security.oauth2.config.annotation.web.configuration.AuthorizationServerConfigurerAdapter;
import org.springframework.security.oauth2.config.annotation.web.configuration.EnableAuthorizationServer;
import org.springframework.security.oauth2.config.annotation.web.configurers.AuthorizationServerEndpointsConfigurer;
import org.springframework.security.oauth2.provider.token.TokenStore;
import org.springframework.security.oauth2.provider.token.store.JwtAccessTokenConverter;

/**
 * 授权服务器配置
 * @author ylc
 * @since 1.0.0
 */
@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;


    /**
     * 使用密码模式需要配置
     */
    @Override
    public void configure(AuthorizationServerEndpointsConfigurer endpoints) {
        endpoints.authenticationManager(authenticationManager)
                .userDetailsService(userService)
                //配置存储令牌策略
                .tokenStore(tokenStore)
                .accessTokenConverter(jwtAccessTokenConverter);
    }

    @Override
    public void configure(ClientDetailsServiceConfigurer clients) throws Exception {
        clients.inMemory()
                //配置client_id
                .withClient("admin")
                //配置client-secret
                .secret(passwordEncoder.encode("112233"))
                //配置访问token的有效期
                .accessTokenValiditySeconds(3600)
                //配置刷新token的有效期
                .refreshTokenValiditySeconds(864000)
                //配置redirect_uri，用于授权成功后跳转
                .redirectUris("http://www.baidu.com")
                //配置申请的权限范围
                .scopes("all")
                //配置grant_type，表示授权类型
                .authorizedGrantTypes("authorization_code","password");
    }
}

用密码模式测试：

发现获取到的令牌已经变成了JWT令牌，将access_token拿到https://jwt.io/ 网站上去解析下可以获得其中内容。

扩展JWT中存储的内容

　有时候我们需要扩展JWT中存储的内容，这里我们在JWT中扩展一个key为enhance，value为enhance info的数据。

继承TokenEnhancer实现一个JWT内容增强器

package com.yjxxt.springsecurityoauth2demo.config;

import org.springframework.security.oauth2.common.DefaultOAuth2AccessToken;
import org.springframework.security.oauth2.common.OAuth2AccessToken;
import org.springframework.security.oauth2.provider.OAuth2Authentication;
import org.springframework.security.oauth2.provider.token.TokenEnhancer;

import java.util.HashMap;
import java.util.Map;

/**
 * JWT内容增强器
 * @author ylc
 * @since 1.0.0
 */
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;
   }
}

创建一个JwtTokenEnhancer实例

package com.yjxxt.springsecurityoauth2demo.config;

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.security.oauth2.provider.token.TokenStore;
import org.springframework.security.oauth2.provider.token.store.JwtAccessTokenConverter;
import org.springframework.security.oauth2.provider.token.store.JwtTokenStore;

/**
 * 使用Jwt存储token的配置
 * @author ylc
 * @since 1.0.0
 */
@Configuration
public class JwtTokenStoreConfig {

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

   @Bean
   public JwtAccessTokenConverter jwtAccessTokenConverter(){
      JwtAccessTokenConverter accessTokenConverter = new JwtAccessTokenConverter();
      //配置JWT使用的秘钥
      accessTokenConverter.setSigningKey("test_key");
      return accessTokenConverter;
   }

   @Bean
   public JwtTokenEnhancer jwtTokenEnhancer() {
      return new JwtTokenEnhancer();
   }
}

在认证服务器配置中配置JWT的内容增强器

package com.yjxxt.springsecurityoauth2demo.config;

import com.yjxxt.springsecurityoauth2demo.component.JwtTokenEnhancer;
import com.yjxxt.springsecurityoauth2demo.service.UserService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.annotation.Qualifier;
import org.springframework.context.annotation.Configuration;
import org.springframework.security.authentication.AuthenticationManager;
import org.springframework.security.crypto.password.PasswordEncoder;
import org.springframework.security.oauth2.config.annotation.configurers.ClientDetailsServiceConfigurer;
import org.springframework.security.oauth2.config.annotation.web.configuration.AuthorizationServerConfigurerAdapter;
import org.springframework.security.oauth2.config.annotation.web.configuration.EnableAuthorizationServer;
import org.springframework.security.oauth2.config.annotation.web.configurers.AuthorizationServerEndpointsConfigurer;
import org.springframework.security.oauth2.provider.token.TokenEnhancer;
import org.springframework.security.oauth2.provider.token.TokenEnhancerChain;
import org.springframework.security.oauth2.provider.token.TokenStore;
import org.springframework.security.oauth2.provider.token.store.JwtAccessTokenConverter;

import java.util.ArrayList;
import java.util.List;

/**
 * 授权服务器配置
 * @author ylc
 * @since 1.0.0
 */
@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;

    /**
     * 使用密码模式需要配置
     */
    @Override
    public void configure(AuthorizationServerEndpointsConfigurer endpoints) {
        TokenEnhancerChain enhancerChain = new TokenEnhancerChain();
        List<TokenEnhancer> delegates = new ArrayList<>();
        //配置JWT的内容增强器
        delegates.add(jwtTokenEnhancer);
        delegates.add(jwtAccessTokenConverter);
        enhancerChain.setTokenEnhancers(delegates);
        endpoints.authenticationManager(authenticationManager)
                .userDetailsService(userService)
                //配置存储令牌策略
                .tokenStore(tokenStore)
                .accessTokenConverter(jwtAccessTokenConverter)
                .tokenEnhancer(enhancerChain);
    }

    @Override
    public void configure(ClientDetailsServiceConfigurer clients) throws Exception {
        clients.inMemory()
                //配置client_id
                .withClient("admin")
                //配置client-secret
                .secret(passwordEncoder.encode("112233"))
                //配置访问token的有效期
                .accessTokenValiditySeconds(3600)
                //配置刷新token的有效期
                .refreshTokenValiditySeconds(864000)
                //配置redirect_uri，用于授权成功后跳转
                .redirectUris("http://www.baidu.com")
                //配置申请的权限范围
                .scopes("all")
                //配置grant_type，表示授权类型
                .authorizedGrantTypes("authorization_code","password");
    }
}

运行项目后使用密码模式来获取令牌，之后对令牌进行解析，发现已经包含扩展的内容。

Java中解析JWT中的内容

添加依赖

<!--jwt 依赖-->
<dependency>
   <groupId>io.jsonwebtoken</groupId>
   <artifactId>jjwt</artifactId>
   <version>0.9.0</version>
</dependency>

修改UserController类，使用jjwt工具类来解析Authorization头中存储的JWT内容

package com.yjxxt.springsecurityoauth2demo.controller;

import io.jsonwebtoken.Jwts;
import org.springframework.security.core.Authentication;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

import javax.servlet.http.HttpServletRequest;
import java.nio.charset.StandardCharsets;

/**
 * @author ylc
 * @since 1.0.0
 */
@RestController
@RequestMapping("/user")
public class UserController {

   @GetMapping("/getCurrentUser")
   public Object getCurrentUser(Authentication authentication, HttpServletRequest request) {
      String header = request.getHeader("Authorization");
      String token = header.substring(header.indexOf("bearer") + 7);
      return Jwts.parser()
            .setSigningKey("test_key".getBytes(StandardCharsets.UTF_8))
            .parseClaimsJws(token)
            .getBody();
   }
}

将令牌放入Authorization头中，访问如下地址获取信息：

http://localhost:8080/user/getCurrentUser

刷新令牌

　在Spring Cloud Security 中使用oauth2时，如果令牌失效了，可以使用刷新令牌通过refresh_token的授权模式再次获取access_token。

只需修改认证服务器的配置，添加refresh_token的授权模式即可。

@Override
public void configure(ClientDetailsServiceConfigurer clients) throws Exception {
    clients.inMemory()
            //配置client_id
            .withClient("admin")
            //配置client-secret
            .secret(passwordEncoder.encode("112233"))
            //配置访问token的有效期
            .accessTokenValiditySeconds(3600)
            //配置刷新token的有效期
            .refreshTokenValiditySeconds(86400)
            //配置redirect_uri，用于授权成功后跳转
            .redirectUris("http://www.baidu.com")
            //配置申请的权限范围
            .scopes("all")
            //配置grant_type，表示授权类型
            .authorizedGrantTypes("authorization_code","password","refresh_token");
}

使用刷新令牌模式来获取新的令牌，访问如下地址：

http://localhost:8080/oauth/token

Spring Security Oauth2 整合单点登录（SSO）

修改配置文件

application.properties

server.port=8081
#防止Cookie冲突，冲突会导致登录验证不通过
server.servlet.session.cookie.name=OAUTH2-CLIENT-SESSIONID01
#授权服务器地址
oauth2-server-url: http://localhost:8080
#与授权服务器对应的配置
security.oauth2.client.client-id=admin
security.oauth2.client.client-secret=112233
security.oauth2.client.user-authorization-uri=${oauth2-server-url}/oauth/authorize
security.oauth2.client.access-token-uri=${oauth2-server-url}/oauth/token
security.oauth2.resource.jwt.key-uri=${oauth2-server-url}/oauth/token_key

在启动类上添加@EnableOAuth2Sso注解来启用单点登录功能

package com.yjxxt.oauth2client01demo;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.autoconfigure.security.oauth2.client.EnableOAuth2Sso;

@SpringBootApplication
@EnableOAuth2Sso
public class Oauth2client01demoApplication {

   public static void main(String[] args) {
      SpringApplication.run(Oauth2client01demoApplication.class, args);
   }

}

添加接口用于获取当前登录用户信息

package com.yjxxt.oauth2client01demo.controller;

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

@RestController
@RequestMapping("/user")
public class UserController {
    
    @GetMapping("/getCurrentUser")
    public Object getCurrentUser(Authentication authentication) {
        return authentication;
    }

}

修改认证服务器配置

修改授权服务器中的AuthorizationServerConfig类，将绑定的跳转路径为

http://localhost:8081/login，并添加获取秘钥时的身份认证

@Override
public void configure(ClientDetailsServiceConfigurer clients) throws Exception {
    clients.inMemory()
            //配置client_id
            .withClient("admin")
            //配置client-secret
            .secret(passwordEncoder.encode("112233"))
            //配置访问token的有效期
            .accessTokenValiditySeconds(3600)
            //配置刷新token的有效期
            .refreshTokenValiditySeconds(864000)
            //配置redirect_uri，用于授权成功后跳转
            // .redirectUris("http://www.baidu.com")
            //单点登录时配置
            .redirectUris("http://localhost:8081/login")
            //配置申请的权限范围
            .scopes("all")
            //自动授权配置
            .autoApprove(true) 
            //配置grant_type，表示授权类型
            .authorizedGrantTypes("authorization_code","password","refresh_token");
}

@Override
public void configure(AuthorizationServerSecurityConfigurer security) {
    // 获取密钥需要身份认证，使用单点登录时必须配置
    security.tokenKeyAccess("isAuthenticated()");
}  

测试

启动授权服务和客户端服务；

访问客户端需要授权的接口http://localhost:8081/user/getCurrentUser

会跳转到授权服务的登录界面；

授权后会跳转到原来需要权限的接口地址，展示登录用户信息；
