import org.springframework.session.data.redis.config.annotation.web.http.EnableRedisHttpSession;

/**

@Configuration
@EnableRedisHttpSession(redisNamespace = "demo:session")
public class HttpSessionConfigurer {

    /**
     * token放在http请求的header中，name=X-Auth-Token
     *
     * @return

    @Bean
    public HeaderHttpSessionIdResolver httpSessionStrategy() {
        return new HeaderHttpSessionIdResolver(AppConstants.HEADER_TOKEN_NAME);
    }

}

其中@EnableRedisHttpSession注解用于启用redis session。
