2、分析解决

可以看出是sping对redis查询的返回结果进行deserialize的时候出错了

然异常的提示也很明确：序列号对象生成这个字节数组的方法是否与默认的反序列化方法相对应；应该就是对称性吧 ， 你用A方法对B进行序列化然后用不对称的反序列化方法C进行反序列号 ， 肯定会有问题。

所以需要另外实现序列化：

为什么要实现序列化接口？

当一个类实现了Serializable接口(该接口仅为标记接口,不包含任何方法定义),表示该类可以序列化.序列化的目的是将一个实现了Serializable接口的对象转换成一个字节序列,可以。 把该字节序列保存起来(例如:保存在一个文件里),以后可以随时将该字节序列恢复为原来的对象。甚至可以将该字节序列放到其他计算机上或者通过网络传输到其他计算机上恢复，只要该计 算机平台存在相应的类就可以正常恢复为原来的对象。 实现：要序列化一个对象，先要创建某些OutputStream对象，然后将其封装在一个ObjectOutputStream对象内，再调用writeObject()方法即可序列化一个对象；反序列化也类似。  
注意：使用对象流写入到文件是不仅要保证该对象是序列化的，而且该对象的成员对象也必须是序列化的。

import org.springframework.context.annotation.Bean;
    import org.springframework.context.annotation.Configuration;
    import org.springframework.data.redis.connection.RedisConnectionFactory;
    import org.springframework.data.redis.core.RedisTemplate;
    import org.springframework.data.redis.serializer.Jackson2JsonRedisSerializer;
    import org.springframework.data.redis.serializer.StringRedisSerializer;
     
    import com.fasterxml.jackson.annotation.JsonAutoDetect;
    import com.fasterxml.jackson.annotation.PropertyAccessor;
    import com.fasterxml.jackson.databind.ObjectMapper;
     
    @Configuration
    public class RedisConfig {
        @Bean
        public RedisTemplate<Object, Object> redisTemplate(RedisConnectionFactory redisConnectionFactory) {
            RedisTemplate<Object, Object> redisTemplate = new RedisTemplate<>();
            redisTemplate.setConnectionFactory(redisConnectionFactory);
     
     
            // 使用Jackson2JsonRedisSerialize 替换默认序列化
            @SuppressWarnings("rawtypes")
            Jackson2JsonRedisSerializer jackson2JsonRedisSerializer = new Jackson2JsonRedisSerializer(Object.class);
     
     
            ObjectMapper objectMapper = new ObjectMapper();
            objectMapper.setVisibility(PropertyAccessor.ALL, JsonAutoDetect.Visibility.ANY);
            objectMapper.enableDefaultTyping(ObjectMapper.DefaultTyping.NON_FINAL);
     
     
            jackson2JsonRedisSerializer.setObjectMapper(objectMapper);
     
     
            // 设置value的序列化规则和 key的序列化规则
            redisTemplate.setValueSerializer(jackson2JsonRedisSerializer);
            redisTemplate.setKeySerializer(new StringRedisSerializer());
            redisTemplate.afterPropertiesSet();
            return redisTemplate;
        }
    }

只需将此配置类加入到springboot启动类下即可解决序列化问题。
