Based OAUTH2 authentication and authorization at Spring Cloud

The Spring Cloudneed to use OAUTH2a unified authentication and authorization services to implement a plurality of micro through to OAUTH服务send some type of grant typecentralized authentication and authorization to obtain access_token, and this token is subject to other micro-service trust, we can follow-up visits access_tokento in order to achieve a unified authentication and authorization micro services.

This example provides four major parts:

eureka: The basic module service registration and discovery
auth: OAUTH2 Certification Authority
account: General micro-services, used to verify authentication and authorization
gateway: Border Gateway (micro services are all behind it)

OAUTH2 roles:

Resource Server: Is authorized to access resources
Authotization Server: OAUTH2 Certification Authority
Resource Owner: User
Client: The client using the API (e.g., Android, IOS, web app)

Grant Type：

authorization_code:
implicit:
password:
refrsh_token:

1. Basic environment

Use Postgresas a storage account, Redisas the Tokenstorage, use docker-composeon server startup Postgresand Redis.

Redis:
  image: sameersbn/redis:latest
  ports:
    - "6379:6379"
  volumes:
    - /srv/docker/redis:/var/lib/redis:Z
  restart: always

PostgreSQL:
  restart: always
  image: sameersbn/postgresql:9.6-2
  ports:
    - "5432:5432"
  environment:
    - DEBUG=false

    - DB_USER=wang
    - DB_PASS=yunfei
    - DB_NAME=order
  volumes:
    - /srv/docker/postgresql:/var/lib/postgresql:Z

2.auth-server

2.1 OAuth2 service configuration

RedisIt used to store token, after the service restarted without re-acquired token.

@Configuration
@EnableAuthorizationServer
public class AuthorizationServerConfig extends AuthorizationServerConfigurerAdapter {
    @Autowired
    private AuthenticationManager authenticationManager;
    @Autowired
    private RedisConnectionFactory connectionFactory;


    @Bean
    public RedisTokenStore tokenStore() {
        return new RedisTokenStore(connectionFactory);
    }


    @Override
    public void configure(AuthorizationServerEndpointsConfigurer endpoints) throws Exception {
        endpoints
                .authenticationManager(authenticationManager)
                .userDetailsService(userDetailsService)//若无，refresh_token会有UserDetailsService is required错误
                .tokenStore(tokenStore());
    }

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

    @Override
    public void configure(ClientDetailsServiceConfigurer clients) throws Exception {
        clients.inMemory()
                .withClient("android")
                .scopes("xx") //此处的scopes是无用的，可以随意设置
                .secret("android")
                .authorizedGrantTypes("password", "authorization_code", "refresh_token")
            .and()
                .withClient("webapp")
                .scopes("xx")
                .authorizedGrantTypes("implicit");
    }
}

2.2 Resource Service Configuration

auth-serverProvide user information, it auth-serveris also aResource Server

@Configuration
@EnableResourceServer
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()
                .authorizeRequests()
                .anyRequest().authenticated()
            .and()
                .httpBasic();
    }
}

@RestController
public class UserController {

    @GetMapping("/user")
    public Principal user(Principal user){
        return user;
    }
}

2.3 Security Configuration

@Configuration
public class SecurityConfig extends WebSecurityConfigurerAdapter {



    @Bean
    public UserDetailsService userDetailsService(){
        return new DomainUserDetailsService();
    }

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

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

    @Bean
    public SecurityEvaluationContextExtension securityEvaluationContextExtension() {
        return new SecurityEvaluationContextExtension();
    }

    //不定义没有password grant_type
    @Override
    @Bean
    public AuthenticationManager authenticationManagerBean() throws Exception {
        return super.authenticationManagerBean();
    }
    


}

2.4 Design authority

Using 用户(SysUser)<-> 角色(SysRole)<-> 权限(SysAuthotity)provided, the relationship between each other 多对多. By DomainUserDetailsService loading the user and permissions.

2.5 Configuration

3.1 Resource Service Configuration

@Configuration
@EnableResourceServer
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()
                .authorizeRequests()
                .anyRequest().authenticated()
            .and()
                .httpBasic();
    }
}

3.2 User Configuration

account is a simple micro-service, using auth-serverauthentication and authorization, specify the user information in its configuration file auth-serverby the address of:

security:
  oauth2:
    resource:
      id: order-service
      user-info-uri: http://localhost:8080/uaa/user
      prefer-token-info: false

3.3 Permissions test controller

Have authoritynot query-demobe able to access, that is, adminthe user

@RestController
public class DemoController {
    @GetMapping("/demo")
    @PreAuthorize("hasAuthority('query-demo')")
    public String getDemo(){
        return "good";
    }
}

4 api-gateway

api-gatewayThere are two roles in this example:

Itself as a client, useimplicit
Acting as the direction of the external app access

4.1 csrf closed and open Oauth2 client support

@Configuration
@EnableOAuth2Sso
public class SecurityConfig extends WebSecurityConfigurerAdapter{
    @Override
    protected void configure(HttpSecurity http) throws Exception {

        http.csrf().disable();

    }

}

4.2 Configuration

zuul:
  routes:
    uaa:
      path: /uaa/**
      sensitiveHeaders:
      serviceId: auth-server
    order:
