gitee项目练习地址：https://gitee.com/xzq25_com/springsecurity.oauth2

OAuth2.0单点登录实践

一、搭建OAuth授权服务器，采用授权码模式+JWT令牌
二、创建服务client：SSOA、SSOB 并进行测试

1，导入依赖：

   <dependencies>

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

        <dependency>

            <artifactId>jjwt</artifactId>
            <version>0.9.1</version>
        </dependency>

    </dependencies>

    <dependencyManagement>
        <dependencies>
            <dependency>
                <groupId>org.springframework.cloud</groupId>

                <scope>import</scope>
            </dependency>
        </dependencies>
    </dependencyManagement>

2，配置AuthorizationServerConfig认证授权服务

/**
 * @author xzq
 * @description: 授权服务器
 * @date 2022/12/5 13:43
 */
@Configuration
@EnableAuthorizationServer
public class AuthorizationServerConfig extends AuthorizationServerConfigurerAdapter {

    @Autowired
    private PasswordEncoder passwordEncoder;

    @Autowired
    private TokenStore jwtTokenStore;

    @Autowired
    private JwtAccessTokenConverter jwtAccessTokenConverter;

    @Autowired
    private JwtTokenEnhancer jwtTokenEnhancer;

    /**
     * @description: 使用密码模式所需配置
     * @author liyonghui
     * @date 2021/12/5 14:27
     */
    @Override
    public void configure(AuthorizationServerEndpointsConfigurer endpoints) throws Exception {

        List<TokenEnhancer> delegates = new ArrayList<>();
        delegates.add(jwtTokenEnhancer);
        delegates.add(jwtAccessTokenConverter);

        //配置JWT内容增强
        TokenEnhancerChain tokenEnhancerChain = new TokenEnhancerChain();
        tokenEnhancerChain.setTokenEnhancers(delegates);

        //配置存储令牌策略
        endpoints.tokenStore(jwtTokenStore)
                .accessTokenConverter(jwtAccessTokenConverter)
                .tokenEnhancer(tokenEnhancerChain);
    }

    @Override
    public void configure(ClientDetailsServiceConfigurer clients) throws Exception {
        clients.inMemory()
                //配置client-id
                .withClient("super")
                //配置client-secret
                .secret(passwordEncoder.encode("xxx"))
                //配置刷新令牌的有效期
                .refreshTokenValiditySeconds(6000)
                //配置redirect-url,用于授权成功后跳转
                .redirectUris("http://localhost:8081/login","http://localhost:8082/login")
                //自动授权
                .autoApprove(true)
                //配置申请的权限范围
                .scopes("user","order","payment")
                //授权类型-使用授权码模式
                .authorizedGrantTypes("authorization_code","refresh_token");
    }

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

3，配置WebSecurityConfigurerAdapter

/**
 * @author xzq
 * @description: TODO
 * @date 2022/12/5 13:35
 */
@Configuration
@EnableWebSecurity
public class SecurityConfig extends WebSecurityConfigurerAdapter {

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

    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http.csrf().disable()
                .authorizeRequests()
                .antMatchers("/oauth/**", "/login/**")
                .permitAll()
                .anyRequest()
                .authenticated()
                .and()
                .formLogin()
                .permitAll();
    }
}

4，配置JwtTokenStoreConfig

/**
 * @author xzq
 * @description: TODO
 * @date 2022/12/5 15:39
 */
@Configuration
public class JwtTokenStoreConfig {

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

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

5，配置JwtTokenEnhancer：Jwt增强

/**
 * @author liyonghui
 * @description: JWT内容增强
 * @date 2021/12/5 15:58
 */
@Component
public class JwtTokenEnhancer implements TokenEnhancer {

    @Override
    public OAuth2AccessToken enhance(OAuth2AccessToken oAuth2AccessToken, OAuth2Authentication oAuth2Authentication) {
        Map<String, Object> objectObjectHashMap = new HashMap<>();
        objectObjectHashMap.put("enhance", "enhance info");
        objectObjectHashMap.put("ceshi", "测试一下增强令牌!");
        ((DefaultOAuth2AccessToken) oAuth2AccessToken).setAdditionalInformation(objectObjectHashMap);
        return oAuth2AccessToken;
    }
}

6，配置pojo类

/**
 * @author xzq
 * @description: TODO
 * @date 2022/12/5 13:37
 */
public class User implements UserDetails {
    private String username;
    private String password;
    private List<GrantedAuthority> authorities;

    public User(String username, String password, List<GrantedAuthority> authorities) {
        this.username = username;
        this.password = password;
        this.authorities = authorities;
    }

    @Override
    public Collection<? extends GrantedAuthority> getAuthorities() {
        return null;
    }

    @Override
    public String getPassword() {
        return null;
    }

    @Override
    public String getUsername() {
        return null;
    }

    @Override
    public boolean isAccountNonExpired() {
        return false;
    }

    @Override
    public boolean isAccountNonLocked() {
        return false;
    }

    @Override
    public boolean isCredentialsNonExpired() {
        return false;
    }

    @Override
    public boolean isEnabled() {
        return false;
    }
}

配置一个用户的账号密码

/**
 * @author xzq
 * @description: TODO
 * @date 2022/12/5 13:34
 */
@Service
public class UserService implements UserDetailsService {
    @Autowired
    private PasswordEncoder passwordEncoder;

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

二、创建服务client：SSOA、SSOB 并进行测试

创建client：SSOA
目录如下：
在这里插入图片描述
1，配置yml文件

server:
  port: 8081
  servlet:
    session:
      cookie:
        name: OAUTH2-CLIENT-SESSION01  # 防止cookie冲突

security:
  oauth2:
    client:
      client-id: super # appid
      client-secret: xxx #appsecret
      user-authorization-uri: http://localhost:8080/oauth/authorize #oauth认证地址
      access-token-uri: http://localhost:8080/oauth/token # 获取access_token

    resource:
     jwt:
        key-uri:  http://localhost:8080/oauth/token_key  # 获取和校验JWT(包装获取access_token)

写一个controller

/**
 * @Author xiaozq
 * @Date 2022/12/12 9:26
 * <p>@Description:</p>
 */
@RequestMapping
@RestController
public class SystemAController {

    @GetMapping("/user")
    public Object userinfo(Authentication authentication){
        return authentication;
    }

    @GetMapping("/info")
    public Object ssoinfo(Authentication authentication){
        return  "系统A单点登录";
    }
}

创建client：SSOB： 复制A系统，改一下yml文件的端口号和cookie名设置，如下：

server:
  port: 8082
  servlet:
    session:
      cookie:
        name: OAUTH2-CLIENT-SESSION02  # 防止cookie冲突

security:
  oauth2:
    client:
      client-id: super # appid
      client-secret: xxx #appsecret
      user-authorization-uri: http://localhost:8080/oauth/authorize #oauth认证地址
      access-token-uri: http://localhost:8080/oauth/token # 获取access_token

    resource:
     jwt:
        key-uri:  http://localhost:8080/oauth/token_key  # 获取和校验JWT(包装获取access_token)

开测！！！！
1，启动授权服务器，启动服务器A、B ：注意授权服务器先启动！！！

2，访问服务器A接口： http://localhost:8081/user

在这里插入图片描述
自动跳转到授权服务器的登录页面
输入用户名，密码： admin 123456

点击登录，则重定向回服务A，成功访问接口

上述截图响应的内容josn格式化如下：

    "authorities": [{
            "authority": "admin"
        }
    ],
