OAuth2.0协议专区-SpringCloud微服务实战-基于OAUTH2.0统一认证授权的微服务基础架构

£可爱£侵袭症+ 提交于 2020-08-14 02:42:10

1.架构图

  技术团队通过一段时间的积累后,我们打算对往后的一些新项目采用Spring Cloud技术栈来实现。大概微服务的架构如下:

 

  • Euraka注册中心集群
  • Zuul网关集群
  • 各模块微服务集群
  • Nginx实现负载均衡
  • Spring Cloud Config 统一配置中心
  • Monitor微服务监控

2.注册中心

  注册中心很简单,这里主要说一下注册中心的高可用配置‘

这里看到我设置了node-1,node-2两个配置文件,就是在启动应用的时候,分别启动不同的配置。

node-1的端口为9010,并向node-2注册,配置如下:

server:
  port: 9010
spring:
  application:
    name: register ##name必须一样,不然高可用会导致unavailable-replicas
eureka:
  instance:
    hostname: register1
  client:
    register-with-eureka: true 
    fetch-registry: true 
    service-url:
      defaultZone: http://register2:9011/eureka/

node-2的端口为9011,并向node-1注册,配置如下:

server:
  port: 9011
spring:
  application:
    name: register ##name必须一样,不然高可用会导致unavailable-replicas
eureka:
  instance:
    hostname: register2
  client:
    register-with-eureka: true 
    fetch-registry: true 
    service-url:
      defaultZone: http://register2:9010/eureka/
这里注意一下:spring.application.name需要一致,不然会出现unavailable-replicas的情况

3.OAUTH2认证服务器

  我这里采用认证服务器与资源服务器分离的方式。

3.1 oauth2 server 配置

  我采取了数据库和redis两种方式来存储token,可以方便切换,生成环境下建议使用redis方式。

AuthorizationServer:

@Configuration
@EnableAuthorizationServer
public class AuthorizationServerConfig extends AuthorizationServerConfigurerAdapter {

  @Autowired
  private AuthenticationManager authenticationManager;

  @Autowired
  private DataSource dataSource;
  @Autowired   private UserDetailsServiceImpl userDetailsService;   @Autowired   private RedisConnectionFactory redisConnectionFactory;   @Bean   RedisTokenStore redisTokenStore(){     return new RedisTokenStore(redisConnectionFactory);   }

token存储数据库

// @Bean
// public JdbcTokenStore jdbcTokenStore(){
//   return new JdbcTokenStore(dataSource);
// }

@Override
public void configure(ClientDetailsServiceConfigurer clients) throws Exception {
  clients.withClientDetails(clientDetails());
}
@Bean public ClientDetailsService clientDetails() {   return new JdbcClientDetailsService(dataSource); }
@Override public void configure(AuthorizationServerEndpointsConfigurer endpoints) throws Exception {    endpoints.tokenStore(redisTokenStore())   .userDetailsService(userDetailsService)   .authenticationManager(authenticationManager);   endpoints.tokenServices(defaultTokenServices()); }

  

/**
* <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(redisTokenStore());
  tokenServices.setSupportRefreshToken(true);
  tokenServices.setClientDetailsService(clientDetails());
  tokenServices.setAccessTokenValiditySeconds(60*60*12); // token有效期自定义设置,默认12小时
  tokenServices.setRefreshTokenValiditySeconds(60 * 60 * 24 * 7);//默认30天,这里修改
  return tokenServices;
}

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

WebSecurityConfig:

@Configuration
public class WebSecurityConfig extends WebSecurityConfigurerAdapter {

@Autowired private UserDetailsServiceImpl userDetailsService; @Bean public PasswordEncoder passwordEncoder() {   return new BCryptPasswordEncoder(); } @Override @Bean public AuthenticationManager authenticationManagerBean() throws Exception {   return super.authenticationManagerBean(); }
@Override protected void configure(AuthenticationManagerBuilder auth) throws Exception {   auth.userDetailsService(userDetailsService)   .passwordEncoder(passwordEncoder()); } @Override protected void configure(HttpSecurity http) throws Exception {   http   .authorizeRequests()   .anyRequest().authenticated()   .and()   .formLogin().and()   .csrf().disable()   .httpBasic(); } @Override public void configure(WebSecurity web) throws Exception {   web.ignoring().antMatchers("/favor.ioc"); } }

3.2 ResourceServer

  因为我们认证中心会提供User信息,所以也是资源服务器。

@Configuration
@EnableResourceServer
public class ResourceServerConfig extends ResourceServerConfigurerAdapter{
  @Override
  public void configure(HttpSecurity http) throws Exception {
  http.csrf().disable()
  .exceptionHandling()
  .authenticationEntryPoint(new Http401AuthenticationEntryPoint("Bearer realm=\"webrealm\""))
  .and()
  .authorizeRequests().anyRequest().authenticated()
  .and()
  .httpBasic();
  }
}

4.资源服务器 Resource

ResourceServer:

@Configuration
@EnableResourceServer
public class ResourceServerConfig extends ResourceServerConfigurerAdapter {
@Override
public void configure(HttpSecurity http) throws Exception {
  http.csrf().disable()
  .exceptionHandling()
  .authenticationEntryPoint(new Http401AuthenticationEntryPoint("Bearer realm=\"webrealm\""))
  .and()
  .authorizeRequests().anyRequest().authenticated()
  .and()
  .httpBasic();
  }
}

主要是application.yml的配置

security:
  oauth2:
    resource:
      id: resource
      user-info-uri: http://10.10.8.2:9030/uaa/user
      prefer-token-info: false

5.Zuul网关

5.1开启支持Sso

@Configuration
@EnableOAuth2Sso
public class SecurityConfig extends WebSecurityConfigurerAdapter{
  @Override
  protected void configure(HttpSecurity http) throws Exception {
    http.csrf().disable();
  }
}

5.2配置

spring:
  application:
    name: Gateway
  zipkin:
    base-url: http://10.10.8.2:9050
server:
  port: 9030
eureka:
  instance:
    prefer-ip-address: true #使用IP注册
    instance-id: ${spring.cloud.client.ipAddress}:${server.port}
  client:
      service-url:
        defaultZone: http://register1:9010/eureka/,http://register2:9011/eureka/
###actuator监控点 start####
endpoints:
  health:
    sensitive: false
    enabled: true
##默认情况下很多端点是不允许访问的,会返回401:Unauthorized
management:
  security:
    enabled: false
###actuator监控点 end####
zuul:
  host:
    connect-timeout-millis: 10000
    socket-timeout-millis: 60000
  routes:
    uaa:
      path: /uaa/**
      strip-prefix: true
      sensitiveHeaders:
      serviceId: auth2.0-center
security:
  basic:
    enabled: false
  oauth2:
    client:
      access-token-uri: http://10.10.8.2:9030/uaa/oauth/token ##网关的地址
      user-authorization-uri: http://10.10.8.2:9030/uaa/oauth/authorize
    resource:
      user-info-uri:  http://10.10.8.2:9030/uaa/user
      prefer-token-info: false
##############end#####################
####超时配置####
ribbon:
  ReadTimeout: 10000
  ConnectTimeout: 10000
  MaxAutoRetries: 1
  MaxAutoRetriesNextServer: 2
  eureka:
    enabled: true
hystrix:
  command:
    default:
      execution:
        timeout:
          enabled: true
        isolation:
          thread:
            timeoutInMilliseconds: 600000
###超时配置###

6.展示

  分别启动register、auth-center、gateway、resource。效果如下:

 

6.1获取access_token


6.2刷新token

 

6.3用access_token获取资源

 

 

 

7.结束

到这里Spring Cloud OAUTH2.0统一认证的骨架就完成了,具体项目拿过来修改就可以满足项目的需求了。
