与Redis数据库共享Spring Session

以下情况:

说明:

我用Spring开发了两个微服务。一种服务是身份验证服务,它会生成会话。另一个服务是ui服务,它需要知道发出请求的客户端是否被授权。经过一番阅读后,我发现与redis共享会话似乎是一个很好的解决方案。 (如果有更好的方法,请纠正我) 对于编码,我遵循示例here

现状: 我的身份验证服务可以正常工作并在Redis中生成会话:

例如:

127.0.0.1:6379> keys *
1) "spring:session:sessions:a4c11990-94a4-4b99-bc77-33f2084e5e8f"
2) "spring:session:sessions:expires:a4c11990-94a4-4b99-bc77-33f2084e5e8f"
3) "spring:session:sessions:26f24541-74dd-4410-84ac-d051a64d1263"
4) "spring:session:index:org.springframework.session.FindByIndexNameSessionRepository.PRINCIPAL_NAME_INDEX_NAME:userA"
5) "spring:session:expirations:1557314160000"
6) "spring:session:sessions:expires:26f24541-74dd-4410-84ac-d051a64d1263"

现在,我想调用ui服务的测试端点。如果会话有效,则此调用应该成功;如果没有有效的会话,则拒绝访问。 Atm我的ui服务中总是出现拒绝访问错误。

SessionConfig

@Configuration
@EnableRedisHttpSession
public class SessionConfig extends AbstractHttpSessionApplicationInitializer {
      @Bean
        public JedisConnectionFactory jedisConnectionFactory() {
            return new JedisConnectionFactory();
        }
@Bean
public HttpSessionIdResolver httpSessionIdResolver() {
    CookieHttpSessionIdResolver resolver = new CookieHttpSessionIdResolver();
    DefaultCookieSerializer cookieSerializer = new DefaultCookieSerializer();
    cookieSerializer.setUseBase64Encoding(false);
    resolver.setCookieSerializer(cookieSerializer);
    return resolver; 
}

在我的主要课堂上,我就读过

@EnableRedisHttpSession

在我的UI服务中:

    public static void main(String[] args) {
        SpringApplication.run(RedistestApplication.class, args);
    }

        public JedisConnectionFactory jedisConnectionFactory() {
            return new JedisConnectionFactory();

public class WebSecurity extends WebSecurityConfigurerAdapter{

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

}
  

控制器

@RestController
public class TestController {

    @GetMapping("/name")
    public String getName() {
        return "Hallo From Test";
    }

}

问题: 我的服务没有任何错误。看来我只是无法使用reddis的会话。在本教程中,作者说cookie中session-id的base64编码可能有问题。我想这可能是问题所在。您对我的实施有任何建议或发现任何错误吗?我是否必须彻底禁用HttpSession? 感谢您的帮助/提示。

编辑: 我刚刚意识到,在我的浏览器Inspect(Firefox)中,我没有任何“ x-auth”字段。我的意图是将身份验证ID(会话ID)保存在标头中,而不是保存为Cookie。因此,我希望我的身份验证服务应在标题中将sessionid设置为x-auth字段。那是对的吗?那么错误似乎来自auth服务?

答案 0 :(得分:0)

在SessionConfig类中尝试将cookieSerializer.setUseBase64Encoding(false)设置为true。在spring-boot.2.0之后,必须对spring-boot应用程序中的会话进行编码。
