Spring Cloud下基于OAUTH2認(rèn)證授權(quán)的實現(xiàn)示例

更新時間：2018年03月09日 10:38:17 作者：智頂筆記

這篇文章主要介紹了Spring Cloud下基于OAUTH2認(rèn)證授權(quán)的實現(xiàn)示例，小編覺得挺不錯的，現(xiàn)在分享給大家，也給大家做個參考。一起跟隨小編過來看看吧

在Spring Cloud需要使用OAUTH2來實現(xiàn)多個微服務(wù)的統(tǒng)一認(rèn)證授權(quán)，通過向OAUTH服務(wù)發(fā)送某個類型的grant type進(jìn)行集中認(rèn)證和授權(quán)，從而獲得access_token，而這個token是受其他微服務(wù)信任的，我們在后續(xù)的訪問可以通過access_token來進(jìn)行，從而實現(xiàn)了微服務(wù)的統(tǒng)一認(rèn)證授權(quán)。

本示例提供了四大部分：

discovery-service:服務(wù)注冊和發(fā)現(xiàn)的基本模塊
auth-server:OAUTH2認(rèn)證授權(quán)中心
order-service:普通微服務(wù)，用來驗證認(rèn)證和授權(quán)
api-gateway:邊界網(wǎng)關(guān)(所有微服務(wù)都在它之后)

OAUTH2中的角色：

Resource Server:被授權(quán)訪問的資源
Authotization Server：OAUTH2認(rèn)證授權(quán)中心
Resource Owner：用戶
Client：使用API的客戶端(如Android 、IOS、web app)

Grant Type：

Authorization Code:用在服務(wù)端應(yīng)用之間
Implicit:用在移動app或者web app(這些app是在用戶的設(shè)備上的，如在手機(jī)上調(diào)起微信來進(jìn)行認(rèn)證授權(quán))
Resource Owner Password Credentials(password):應(yīng)用直接都是受信任的(都是由一家公司開發(fā)的，本例子使用
Client Credentials:用在應(yīng)用API訪問。

1.基礎(chǔ)環(huán)境

使用Postgres作為賬戶存儲，Redis作為Token存儲，使用docker-compose在服務(wù)器上啟動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

2.auth-server

2.1 OAuth2服務(wù)配置

Redis用來存儲token，服務(wù)重啟后，無需重新獲取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)
    .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") //此處的scopes是無用的，可以隨意設(shè)置
    .secret("android")
    .authorizedGrantTypes("password", "authorization_code", "refresh_token")
   .and()
    .withClient("webapp")
    .scopes("xx")
    .authorizedGrantTypes("implicit");
 }
}

2.2 Resource服務(wù)配置

auth-server提供user信息，所以auth-server也是一個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;
 }
}

2.3 安全配置

@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();
 }

 //不定義沒有password grant_type
 @Override
 @Bean
 public AuthenticationManager authenticationManagerBean() throws Exception {
  return super.authenticationManagerBean();
 }

}

2.4 權(quán)限設(shè)計

采用用戶(SysUser) 角色(SysRole) 權(quán)限(SysAuthotity)設(shè)置，彼此之間的關(guān)系是多對多。通過DomainUserDetailsService 加載用戶和權(quán)限。

2.5 配置

spring:
 profiles:
 active: ${SPRING_PROFILES_ACTIVE:dev}
 application:
  name: auth-server

 jpa:
 open-in-view: true
 database: POSTGRESQL
 show-sql: true
 hibernate:
  ddl-auto: update
 datasource:
 platform: postgres
 url: jdbc:postgresql://192.168.1.140:5432/auth
 username: wang
 password: yunfei
 driver-class-name: org.postgresql.Driver
 redis:
 host: 192.168.1.140

server:
 port: 9999


eureka:
 client:
 serviceUrl:
  defaultZone: http://${eureka.host:localhost}:${eureka.port:8761}/eureka/



logging.level.org.springframework.security: DEBUG

logging.leve.org.springframework: DEBUG

##很重要
security:
 oauth2:
 resource:
  filter-order: 3

2.6 測試數(shù)據(jù)

data.sql里初始化了兩個用戶admin->ROLE_ADMIN->query_demo,wyf->ROLE_USER

3.order-service

3.1 Resource服務(wù)配置

@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 用戶信息配置

order-service是一個簡單的微服務(wù)，使用auth-server進(jìn)行認(rèn)證授權(quán)，在它的配置文件指定用戶信息在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

3.3 權(quán)限測試控制器

具備authority未query-demo的才能訪問，即為admin用戶

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

4 api-gateway

api-gateway在本例中有2個作用：

本身作為一個client，使用implicit
作為外部app訪問的方向代理

4.1 關(guān)閉csrf并開啟Oauth2 client支持

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

  http.csrf().disable();
 }
}

4.2 配置

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

5 演示

5.1 客戶端調(diào)用

使用Postman向http://localhost:8080/uaa/oauth/token發(fā)送請求獲得access_token(admin用戶的如7f9b54d4-fd25-4a2c-a848-ddf8f119230b)

admin用戶
