spring boot security 登录成功后session问题。

Question

最近在处理一个springboot的项目session共享问题，项目采用的是springboot2.0，使用了spring security控制登录和权限，不加session共享项目是正常的，加了之后报各种基础类没有序列化。加session共享也是参考过各种网上方案，用的是这个：
pom.xml添加如下依赖

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-data-redis</artifactId>
</dependency>
<dependency>
    <groupId>org.springframework.session</groupId>
    <artifactId>spring-session-data-redis</artifactId>
</dependency>

增加一个redis共享httpSession的配置类

@Configuration
@EnableRedisHttpSession
public class RedisSessionConfig {
    @Bean
    public RedisTemplate<Object, Object> sessionRedisTemplate(
            RedisConnectionFactory connectionFactory) {
        RedisTemplate<Object, Object> template = new RedisTemplate<>();
        template.setKeySerializer(new GenericJackson2JsonRedisSerializer());
        template.setHashKeySerializer(new GenericJackson2JsonRedisSerializer());
        template.setConnectionFactory(connectionFactory);
        return template;
    }
}

其他redi配置就不多说了，程序启动是正常的，也能打开登录界面。密码错误等校验都是正常的，但是登录成功后发现报有类没有序列化，这个是spring-session-code里面的类，spring应该不会犯这种错误才对啊！我查了一下，是spring security登录成功后把相关的认证信息通过"SPRING_SECURITY_CONTEXT"这个key放到了session里面，
想请教使用springboot和security的大神们，你们是用什么做session共享的？
有什么办法不放这个session到redis里面？或者其他的解决方案？
求解，谢谢...
