1、文章前言介绍

在前面文章中我们学习了OAuth2的一些基本概念，对OAuth2有了基本的认识，也对OAuth2.0的令牌等进行数据库存储，对应博客：jdbc方式的数据存储，然后如果不想存储令牌可以实现？

IDEA中，Ctrl+Alt+B，可以看到TokenStore的实现，有如下几种：

ok，其实对于token存储有如上方式，分别进行介绍：

• InMemoryTokenStore，默认存储，保存在内存
• JdbcTokenStore，access_token存储在数据库
• JwtTokenStore，JWT这种方式比较特殊，这是一种无状态方式的存储，不进行内存、数据库存储，只是JWT中携带全面的用户信息，保存在jwt中携带过去校验就可以
• RedisTokenStore，将 access_token 存到 redis 中。
• JwkTokenStore，将 access_token 保存到 JSON Web Key。

2、例子实验验证

实验环境准备：

• IntelliJ IDEA
• Maven3.+版本
  新建SpringBoot Initializer项目，可以命名oauth2-jwt
  

主要加入如下配置：

 <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-web</artifactId>
        </dependency>
 <!-- Spring Cloud Oauth2-->
        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-oauth2</artifactId>
        </dependency>
        <!-- Spring Cloud Security-->
        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-security</artifactId>
        </dependency>

TokenStore：

   @Bean
    public TokenStore jwtTokenStore() {
        //基于jwt实现令牌（Access Token）
        return new JwtTokenStore(accessTokenConverter());
    }

JwtAccessTokenConverter ：

 @Bean
    public JwtAccessTokenConverter accessTokenConverter(){
        JwtAccessTokenConverter converter = new JwtAccessTokenConverter(){
            @Override
            public OAuth2AccessToken enhance(OAuth2AccessToken accessToken, OAuth2Authentication authentication) {
                String grantType = authentication.getOAuth2Request().getGrantType();
                //授权码和密码模式才自定义token信息
                if(AUTHORIZATION_CODE.equals(grantType) || GRANT_TYPE_PASSWORD.equals(grantType)) {
                    String userName = authentication.getUserAuthentication().getName();
                    // 自定义一些token 信息
                    Map<String, Object> additionalInformation = new HashMap<String, Object>(16);
                    additionalInformation.put("user_name", userName);
                    additionalInformation = Collections.unmodifiableMap(additionalInformation);
                    ((DefaultOAuth2AccessToken) accessToken).setAdditionalInformation(additionalInformation);
                }
                OAuth2AccessToken token = super.enhance(accessToken, authentication);
                return token;
            }
        };
        // 设置签署key
        converter.setSigningKey("signingKey");
        return converter;
    }

配置accessTokenConverter

 @Override
    public void configure(AuthorizationServerEndpointsConfigurer endpoints) throws Exception {
        endpoints.tokenStore(jwtTokenStore()).authenticationManager(authenticationManager)
                //自定义accessTokenConverter
                .accessTokenConverter(accessTokenConverter())
                //支持获取token方式
                .allowedTokenEndpointRequestMethods(HttpMethod.GET, HttpMethod.POST,HttpMethod.PUT,HttpMethod.DELETE,HttpMethod.OPTIONS);
    }

3、功能简单测试

访问授权链接，在浏览器访问就可以，授权码模式response_type参数传code：
http://localhost:8888/oauth/authorize?client_id=cms&client_secret=secret&response_type=code

因为没登录，所以会返回SpringSecurity的默认登录页面，具体代码是 http .formLogin().permitAll();，如果要弹窗登录的，可以配置http.httpBasic();，这种配置是没有登录页面的，自定义登录页面可以这样配置http.formLogin().loginPage("/login").permitAll()

如图，输入SpringSecurity配置的数据库密码

登录成功，返回redirect_uri，拿到授权码

重定向回redirect_uri，http://localhost:8084/cms/login?code=???

配置一下请求头的授权参数，用Basic Auth方式，username即client_id，password即client_secret

拿到授权码之后去获取token，本教程使用授权码方式

JWT方式的token

{
    "access_token":"eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJleHAiOjE1OTIzNzYwNjEsInVzZXJfbmFtZSI6Im5pY2t5IiwiYXV0aG9yaXRpZXMiOlsiUk9MRV9hZG1pbiJdLCJqdGkiOiJiM2IwZGExNS1mMmQyLTRlN2MtYTUwNC1iMzg5YjkxMjM0MDMiLCJjbGllbnRfaWQiOiJjbXMiLCJzY29wZSI6WyJhbGwiXX0.TpIBd9Gtb4M7sC1MSQsxsn8mwnhAm59CUBZPU7jwdnE",
