Part1序

因为目前做了一个基于Spring Cloud的微服务项目，所以了解到了OAuth2，打算整合一下OAuth2来实现统一授权。关于OAuth是一个关于授权的开放网络标准，目前的版本是2.0，这里我就不多做介绍了。

Part2开发环境

• Windows10
• Intellij Idea2018.2
• jdk1.8
• redis3.2.9
• Spring Boot 2.0.2 Release
• Spring Cloud Finchley.RC2
• Spring 5.0.6

Part3项目目录

• eshop                                      —— 父级工程，管理jar包版本
• eshop-server                 —— Eureka服务注册中心
• eshop-gateway              —— Zuul网关
• eshop-auth                    —— 授权服务
• eshop-member              —— 会员服务
• eshop-email                   —— 邮件服务（暂未使用）
• eshop-common              —— 通用类 关于如何构建一个基本的Spring Cloud 微服务这里就不赘述了

Part4授权服务

首先构建eshop-auth服务，引入相关依赖

接下来，配置Mybatis、redis、eureka，贴一下配置文件

    cache-enabled: true #开启二级缓存
    call-setters-on-nulls: true #map空列不显示问题
  mapper-locations:
    - classpath:mybatis/*.xml

AuthApplication添加@EnableDiscoveryClient和@MapperScan注解。

接下来配置认证服务器AuthorizationServerConfig ，并添加@Configuration和@EnableAuthorizationServer注解，其中ClientDetailsServiceConfigurer配置在内存中，当然也可以从数据库读取，以后慢慢完善。

@Configuration
@EnableAuthorizationServer
public class AuthorizationServerConfig extends AuthorizationServerConfigurerAdapter {
 
    @Autowired
    private AuthenticationManager authenticationManager;
 
    @Autowired
    private DataSource dataSource;
 
    @Autowired
    private RedisConnectionFactory redisConnectionFactory;
 
    @Autowired
    private MyUserDetailService userDetailService;
 
    @Bean
    public TokenStore tokenStore() {
        return new RedisTokenStore(redisConnectionFactory);
    }
 
    @Override
    public void configure(AuthorizationServerSecurityConfigurer security) throws Exception {
        security
                .allowFormAuthenticationForClients()
                .tokenKeyAccess("permitAll()")
                .checkTokenAccess("isAuthenticated()");
    }
 
    @Override
    public void configure(ClientDetailsServiceConfigurer clients) throws Exception {
       // clients.withClientDetails(clientDetails());
        clients.inMemory()
                .withClient("android")
                .scopes("read")
                .secret("android")
                .authorizedGrantTypes("password", "authorization_code", "refresh_token")
                .and()
                .withClient("webapp")
                .scopes("read")
                .authorizedGrantTypes("implicit")
                .and()
                .withClient("browser")
                .authorizedGrantTypes("refresh_token", "password")
                .scopes("read");
    }
    @Bean
    public ClientDetailsService clientDetails() {
        return new JdbcClientDetailsService(dataSource);
    }
 
    @Bean
    public WebResponseExceptionTranslator webResponseExceptionTranslator(){
        return new MssWebResponseExceptionTranslator();
    }
 
    @Override
    public void configure(AuthorizationServerEndpointsConfigurer endpoints) throws Exception {
        endpoints.tokenStore(tokenStore())
                .userDetailsService(userDetailService)
                .authenticationManager(authenticationManager);
        endpoints.tokenServices(defaultTokenServices());
        //认证异常翻译
       // endpoints.exceptionTranslator(webResponseExceptionTranslator());
    }
 
    /**
     * <p>注意，自定义TokenServices的时候，需要设置@Primary，否则报错，</p>
     * @return
     */
    @Primary
    @Bean
    public DefaultTokenServices defaultTokenServices(){
        DefaultTokenServices tokenServices = new DefaultTokenServices();
        tokenServices.setTokenStore(tokenStore());
        tokenServices.setSupportRefreshToken(true);
        //tokenServices.setClientDetailsService(clientDetails());
        // token有效期自定义设置，默认12小时
        tokenServices.setAccessTokenValiditySeconds(60*60*12);
        // refresh_token默认30天
        tokenServices.setRefreshTokenValiditySeconds(60 * 60 * 24 * 7);
        return tokenServices;
    }
}

在上述配置中，认证的token是存到redis里的，如果你这里使用了Spring5.0以上的版本的话，使用默认的RedisTokenStore认证时会报如下异常：

nested exception is java.lang.NoSuchMethodError: org.springframework.data.redis.connection.RedisConnection.set([B[B)V

原因是spring-data-redis 2.0版本中set(String,String)被弃用了，要使用RedisConnection.stringCommands().set(…)，所有我自定义一个RedisTokenStore，代码和RedisTokenStore一样，只是把所有conn.set(…)都换成conn..stringCommands().set(…)，测试后方法可行。

配置资源服务器

@Configuration
@EnableResourceServer
@Order(3)
public class ResourceServerConfig extends ResourceServerConfigurerAdapter {
    @Override
    public void configure(HttpSecurity http) throws Exception {
        http.csrf().disable()
            .exceptionHandling()
            .authenticationEntryPoint((request, response, authException) -> response.sendError(HttpServletResponse.SC_UNAUTHORIZED))
            .and()
            .requestMatchers().antMatchers("/api/**")
            .and()
            .authorizeRequests()
            .antMatchers("/api/**").authenticated()
            .and()
            .httpBasic();
    }
}

配置Spring Security

@Configuration
@EnableWebSecurity
@Order(2)
public class SecurityConfig extends WebSecurityConfigurerAdapter {
    @Autowired
    private MyUserDetailService userDetailService;
 
    @Bean
    public PasswordEncoder passwordEncoder() {
        //return new BCryptPasswordEncoder();
        return new NoEncryptPasswordEncoder();
    }
 
    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http.requestMatchers().antMatchers("/oauth/**")
                .and()
                .authorizeRequests()
                .antMatchers("/oauth/**").authenticated()
                .and()
                .csrf().disable();
    }
 
    @Override
    protected void configure(AuthenticationManagerBuilder auth) throws Exception {
        auth.userDetailsService(userDetailService).passwordEncoder(passwordEncoder());
    }
 
    /**
     * 不定义没有password grant_type
     *
     * @return
     * @throws Exception
     */
    @Override
    @Bean
    public AuthenticationManager authenticationManagerBean() throws Exception {
        return super.authenticationManagerBean();
    }
}

可以看到ResourceServerConfig 是比SecurityConfig 的优先级低的。

二者的关系：

• ResourceServerConfig 用于保护oauth相关的endpoints，同时主要作用于用户的登录(form login,Basic auth)
• SecurityConfig 用于保护oauth要开放的资源，同时主要作用于client端以及token的认证(Bearer auth)

所以我们让SecurityConfig优先于ResourceServerConfig，且在SecurityConfig 不拦截oauth要开放的资源，在ResourceServerConfig 中配置需要token验证的资源，也就是我们对外提供的接口。所以这里对于所有微服务的接口定义有一个要求，就是全部以/api开头。

如果这里不这样配置的话，在你拿到access_token去请求各个接口时会报 invalid_token 的提示。

另外，由于我们自定义认证逻辑，所以需要重写UserDetailService

@Service("userDetailService")
public class MyUserDetailService implements UserDetailsService {
 
    @Autowired
    private MemberDao memberDao;
 
    @Override
    public UserDetails loadUserByUsername(String memberName) throws UsernameNotFoundException {
        Member member = memberDao.findByMemberName(memberName);
        if (member == null) {
            throw new UsernameNotFoundException(memberName);
        }
        Set<GrantedAuthority> grantedAuthorities = new HashSet<>();
        // 可用性 :true:可用 false:不可用
        boolean enabled = true;
        // 过期性 :true:没过期 false:过期
        boolean accountNonExpired = true;
        // 有效性 :true:凭证有效 false:凭证无效
        boolean credentialsNonExpired = true;
        // 锁定性 :true:未锁定 false:已锁定
        boolean accountNonLocked = true;
        for (Role role : member.getRoles()) {
            //角色必须是ROLE_开头，可以在数据库中设置
            GrantedAuthority grantedAuthority = new SimpleGrantedAuthority(role.getRoleName());
            grantedAuthorities.add(grantedAuthority);
            //获取权限
            for (Permission permission : role.getPermissions()) {
                GrantedAuthority authority = new SimpleGrantedAuthority(permission.getUri());
                grantedAuthorities.add(authority);
            }
        }
        User user = new User(member.getMemberName(), member.getPassword(),
                enabled, accountNonExpired, credentialsNonExpired, accountNonLocked, grantedAuthorities);
        return user;
    }
 
}

密码验证为了方便我使用了不加密的方式，重写了PasswordEncoder，实际开发还是建议使用BCryptPasswordEncoder。

public class NoEncryptPasswordEncoder implements PasswordEncoder {
 
    @Override
    public String encode(CharSequence charSequence) {
        return (String) charSequence;
    }
 
    @Override
    public boolean matches(CharSequence charSequence, String s) {
        return s.equals((String) charSequence);
    }
}

另外，OAuth的密码模式需要AuthenticationManager支持

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

定义一个Controller，提供两个接口，/api/member用来获取当前用户信息，/api/exit用来注销当前用户

@RestController
@RequestMapping("/api")
public class MemberController {
 
    @Autowired
    private MyUserDetailService userDetailService;
 
    @Autowired
    private ConsumerTokenServices consumerTokenServices;
 
    @GetMapping("/member")
    public Principal user(Principal member) {
        return member;
    }
 
    @DeleteMapping(value = "/exit")
    public Result revokeToken(String access_token) {
        Result result = new Result();
        if (consumerTokenServices.revokeToken(access_token)) {
            result.setCode(ResultCode.SUCCESS.getCode());
            result.setMessage("注销成功");
        } else {
            result.setCode(ResultCode.FAILED.getCode());
            result.setMessage("注销失败");
        }
        return result;
    }
}

    }
}

接下来分别启动eshop-server、eshop-member、eshop-auth、eshop-gateway。

先发送一个请求测试一下未认证的效果

获取认证

使用access_token请求auth服务下的用户信息接口

使用access_token请求member服务下的用户信息接口

请求member服务的query接口

请求member服务的hello接口，数据库里并没有给用户hello权限

刷新token

注销

Part7获取认证时返回401

获取认证时返回401，如下：

{
    "timestamp": "2019-08-13T03:25:27.161+0000",
    "status": 401,
    "error": "Unauthorized",
    "message": "Unauthorized",
    "path": "/oauth/token"
}

原因是在发起请求的时候没有添加Basic Auth认证，如下图：添加Basic Auth认证后会在headers添加一个认证消息头添加Basic Auth认证的信息在代码中有体现：

Part8客户端信息和token信息从MySQL数据库中获取

现在客户端信息都是存在内存中的，生产环境肯定不可以这么做，要支持客户端的动态添加或删除，所以我选择把客户端信息存到MySQL中。

首先，创建数据表，数据表的结构官方已经给出，地址在

https://github.com/spring-projects/spring-security-oauth/blob/master/spring-security-oauth2/src/test/resources/schema.sql

其次，需要修改一下sql脚本，把主键的长度改为128，LONGVARBINARY类型改为blob，调整后的sql脚本：

create table oauth_client_details (
  client_id VARCHAR(128) PRIMARY KEY,
  resource_ids VARCHAR(256),
  client_secret VARCHAR(256),
  scope VARCHAR(256),
  authorized_grant_types VARCHAR(256),
  web_server_redirect_uri VARCHAR(256),
  authorities VARCHAR(256),
  access_token_validity INTEGER,
  refresh_token_validity INTEGER,
  additional_information VARCHAR(4096),
  autoapprove VARCHAR(256)
);
 
create table oauth_client_token (
  token_id VARCHAR(256),
  token BLOB,
  authentication_id VARCHAR(128) PRIMARY KEY,
  user_name VARCHAR(256),
  client_id VARCHAR(256)
);
 
create table oauth_access_token (
  token_id VARCHAR(256),
  token BLOB,
  authentication_id VARCHAR(128) PRIMARY KEY,
  user_name VARCHAR(256),
  client_id VARCHAR(256),
  authentication BLOB,
  refresh_token VARCHAR(256)
);
 
create table oauth_refresh_token (
  token_id VARCHAR(256),
  token BLOB,
  authentication BLOB
);
 
create table oauth_code (
  code VARCHAR(256), authentication BLOB
);
 
create table oauth_approvals (
 userId VARCHAR(256),
 clientId VARCHAR(256),
 scope VARCHAR(256),
 status VARCHAR(10),
 expiresAt TIMESTAMP,
 lastModifiedAt TIMESTAMP
);
 
 
-- customized oauth_client_details table
create table ClientDetails (
  appId VARCHAR(128) PRIMARY KEY,
  resourceIds VARCHAR(256),
  appSecret VARCHAR(256),
  scope VARCHAR(256),
  grantTypes VARCHAR(256),
  redirectUrl VARCHAR(256),
  authorities VARCHAR(256),
  access_token_validity INTEGER,
  refresh_token_validity INTEGER,
  additionalInformation VARCHAR(4096),
  autoApproveScopes VARCHAR(256)
);

调整后的sql脚步也放到了GitHub中，需要的可以自行下载然后在eshop_member数据库创建数据表，将客户端信息添加到oauth_client_details表中如果你的密码不是明文，记得client_secret需要加密后存储。

然后修改代码，配置从数据库读取客户端信息接下来启动服务测试即可。

获取授权

获取用户信息

刷新token

打开数据表发现token这些信息并没有存到表中，因为tokenStore使用的是redis方式，我们可以替换为从数据库读取。修改配

重启服务再次测试

查看数据表，发现token数据已经存到表里了。

Part9源码

关于代码和数据表sql已经上传到GitHub。

注意把数据库和redis替换成自己的地址
