在Spring Cloud
需要使用OAUTH2
来实现多个微服务的统一认证授权,通过向OAUTH服务
发送某个类型的grant type
进行集中认证和授权,从而获得access_token
,而这个token是受其他微服务信任的,我们在后续的访问可以通过access_token
来进行,从而实现了微服务的统一认证授权。
本示例提供了四大部分:
discovery-service
:服务注册和发现的基本模块auth-server
:OAUTH2认证授权中心order-service
:普通微服务,用来验证认证和授权api-gateway
:边界网关(所有微服务都在它之后)
OAUTH2中的角色:
Resource Server
:被授权访问的资源Authotization Server
:OAUTH2认证授权中心Resource Owner
: 用户Client
:使用API的客户端(如Android 、IOS、web app)
Grant Type:
authorization_code
:implicit
:password
:refrsh_token
:
使用Postgres
作为账户存储,Redis
作为Token
存储,使用docker-compose
在服务器上启动Postgres
和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
Redis
用来存储token
,服务重启后,无需重新获取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");
}
}
auth-server
提供user信息,所以auth-server
也是一个Resource 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;
}
}
@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();
}
}
采用用户(SysUser)
<->角色(SysRole)
<->权限(SysAuthotity)
设置,彼此之间的关系是多对多
。通过DomainUserDetailsService
加载用户和权限。
spring:
profiles:
active: ${SPRING_PROFILES_ACTIVE:dev}
application:
name: auth-server
jpa:
open-in-view: true
database: POSTGRESQL
show-sql: true

logging.level.org.springframework.security: DEBUG
logging.leve.org.springframework: DEBUG
##很重要
security:
oauth2:
resource:
filter-order: 3
data.sql
里初始化了两个用户admin
->ROLE_ADMIN
->query_demo
,wyf
->ROLE_USER
@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();
}
}
order-service
是一个简单的微服务,使用auth-server
进行认证授权,在它的配置文件指定用户信息在auth-server
的地址即可:
security:
oauth2:
resource:
id: order-service
user-info-uri: http://localhost:8080/uaa/user
prefer-token-info: false
具备authority
未query-demo
的才能访问,即为admin
用户
@RestController
public class DemoController {
@GetMapping("/demo")
@PreAuthorize("hasAuthority('query-demo')")
public String getDemo(){
return "good";
}
}
api-gateway
在本例中有2个作用:
-
本身作为一个client,使用
implicit
-
作为外部app访问的方向代理
@Configuration
@EnableOAuth2Sso
public class SecurityConfig extends WebSecurityConfigurerAdapter{
@Override
protected void configure(HttpSecurity http) throws Exception {
http.csrf().disable();
}
}
zuul:
routes:
uaa:
path: /uaa/**
sensitiveHeaders:
serviceId: auth-server
order:
path: /order/**
sensitiveHeaders:
serviceId: order-service
add-proxy-headers: true
security:
oauth2:
client:
access-token-uri: http://localhost:8080/uaa/oauth/token
user-authorization-uri: http://localhost:8080/uaa/oauth/authorize
client-id: webapp
resource:
user-info-uri: http://localhost:8080/uaa/user
prefer-token-info: false
feign client没有将access token放入请求头里,需定义一个OAuth2FeignRequestInterceptor
的bean:
使用Postman
向http://localhost:8080/uaa/oauth/token
发送请求获得access_token
(admin用户的如7f9b54d4-fd25-4a2c-a848-ddf8f119230b
)
暂时没有做测试,下次补充。
所谓注销只需将access_token
和refresh_token
失效即可,我们模仿org.springframework.security.oauth2.provider.endpoint.TokenEndpoint
写一个使access_token
和refresh_token
失效的Endpoint
:
@FrameworkEndpoint
public class RevokeTokenEndpoint {
@Autowired
@Qualifier("consumerTokenServices")
ConsumerTokenServices consumerTokenServices;
@RequestMapping(method = RequestMethod.DELETE, value = "/oauth/token")
@ResponseBody
public String revokeToken(String access_token) {
if (consumerTokenServices.revokeToken(access_token)){
return "注销成功";
}else{
return "注销失败";
}
}
}
