本文介绍如何使用Spring Cloud OAuth2构建鉴权服务。主要内容包括添加依赖、配置授权服务器及资源服务器、实现UserDetailsService接口等步骤，并通过curl命令测试获取access_token。

最近在项目中使用了OAuth2做鉴权服务,将主要步骤整理一下:
使用Spring Cloud OAuth2起步依赖会比较简单,在pom.xml中添加依赖

<dependency>
    <groupId>org.springframework.cloud</groupId>
    <artifactId>spring-cloud-starter-oauth2</artifactId>
</dependency> 
//父项目中使用了cloud版本 Brixton.SR5
<dependencyManagement>
    <dependencies>
        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-dependencies</artifactId>
            <version>Brixton.SR5</version>
            <type>pom</type>
            <scope>import</scope>
        </dependency>
    </dependencies>
</dependencyManagement>

加入Spring Cloud OAuth2后会包含Spring-Security,Spring-Security-OAuth2等依赖.
OAuth2两部分AuthorizationServer和ResourceServer,使用注解@EnableAuthorizationServer的类实现AuthorizationServerConfigurer(一般AuthorizationServerConfigurerAdapter)接口,就可以对授权服务进行配置.
主要配置三个部分,ClientDetailsServiceConfigurer客户端连接详情,grant_type,scopes等,AuthorizationServerSecurityConfigurer,访问token接口的安全限制,如tokenKeyAccess,checkTokenAccess,AuthorizatinoServerEndpointsConfigurer,授权和token的服务,如authenticationManager,passwordEncode,userDetailsService.

@Configuration
@EnableAuthorizationServer
protected static class OAuth2AuthorizationConfig extends AuthorizationServerConfigurerAdapter {

    private TokenStore tokenStore = new InMemoryTokenStore();

    @Autowired
    @Qualifier("authenticationManagerBean")
    private AuthenticationManager authenticationManager;

    @Autowired
    private AuthUserDetailsService userDetailsService;

    @Override
    public void configure(ClientDetailsServiceConfigurer clients) throws Exception {
        clients.inMemory()
               .withClient("browser")
               .authorizedGrantTypes("refresh_token", "password")
               .scopes("ui");
    }

    @Override
    public void configure(AuthorizationServerEndpointsConfigurer endpoints) throws Exception {
        endpoints
                .tokenStore(tokenStore)
                .authenticationManager(authenticationManager)
                .userDetailsService(userDetailsService);
    }

    @Override
    public void configure(AuthorizationServerSecurityConfigurer oauthServer) throws Exception {
        oauthServer
                .tokenKeyAccess("permitAll()")
                .checkTokenAccess("isAuthenticated()");
    }
}

配置WebSecurityConfig,是token服务能够访问.

@Configuration
@EnableWebSecurity
protected static class webSecurityConfig extends WebSecurityConfigurerAdapter {

    @Autowired
    private AuthUserDetailsService userDetailsService;

    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http
            .authorizeRequests().anyRequest().authenticated()
        .and()
            .csrf().disable();
    }

    @Override
    protected void configure(AuthenticationManagerBuilder auth) throws Exception {
        auth.userDetailsService(userDetailsService)
                .passwordEncoder(new BCryptPasswordEncoder());
    }

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

将配置类集成到Application.java类中,

@SpringBootApplication
@EnableResourceServer
@EnableDiscoveryClient
@EnableGlobalMethodSecurity(prePostEnabled = true)
public class Application {
    public static void main(String[] args) {
        SpringApplication.run(Application.class, args);
    }
    protected static class webSecurityConfig extends WebSecurityConfigurerAdapter;
    protected static class OAuth2AuthorizationConfig extends AuthorizationServerConfigurerAdapter;
}

实现UserDetailsService类,

@Service
public class AuthUserDetailsService implements UserDetailsService {

    @Autowired
    private UserRepository repository;

    @Override
    public UserDetails loadUserByUsername(String username) throws UsernameNotFoundException {

        User user = repository.findByUsername(username);

        if (user == null) {
            throw new UsernameNotFoundException(username);
        }

        return user;
    }
}

通过JPA查询数据库当前用户,密码匹配即可生成access-token.
测试, 通过curl命令发送POST请求到接口uaa/oauth/token:

curl -H "Authorization:Basic YnJvd3Nlcjo=" -d "grant_type=password&scope=ui&username=test01&password=123456" localhost:4000/uaa/oauth/token

//得到结果
{"access_token":"18471940-5d80-4f17-8b57-8bb920214121","token_type":"bearer","refresh_token":"db4ed1dc-8ce1-4b91-8fad-9749022fea64","expires_in":41394,"scope":"ui"}

得到access_token后,可以在请求中携带信息获得ResourceServer中的资源:

curl -H "Authorization:Bearer 057c2f03-e69a-446e-bdf1-2e9d183e8814" localhost/accounts/current
//结果
{"id":2,"name":"test01","description":"test01"}
