使用GenericFastJsonRedisSerializer的RedisTemplate无法反序列化父类属性

Question

首先，我创建了一个实现Serializable的父类，然后创建一个子类来扩展它。我使用带有GenericFastJsonRedisSerializer配置的RedisTemplate将数据放入redis，但是当我从Reids取回数据时，数据是changed.Please告诉我为什么和如何修复它？

@Data
public class People implements Serializable {
    public Long id;
    public String name;
}

@EqualsAndHashCode(callSuper = true)
@Data
public class Student extends People{
    private String sName;
}

    @Bean(name = "redisTemplate")
    public RedisTemplate<String, Object> redisTemplate(RedisConnectionFactory factory) {
        RedisTemplate<String, Object> redisTemplate = new RedisTemplate<>();
        redisTemplate.setConnectionFactory(factory);

        RedisSerializer keySerializer = new StringRedisSerializer();
        RedisSerializer valueSerializer = new GenericFastJsonRedisSerializer();

        redisTemplate.setDefaultSerializer(valueSerializer);
        redisTemplate.setKeySerializer(keySerializer);
        redisTemplate.setValueSerializer(valueSerializer);
        redisTemplate.setHashKeySerializer(keySerializer);
        redisTemplate.setHashValueSerializer(valueSerializer);

        RedisUtil.init(redisTemplate);
        return redisTemplate;
    }

    @Autowired
    private RedisTemplate<String, Object> redisTemplate;

    @Test
    public void cacheDeserialize(){
        Student student = new Student();
        student.setId(11111111111111111L);
        student.setName("parent name");
        student.setSName("child name");
        redisTemplate.opsForValue().set("parent-child-test", student);
        Object value = redisTemplate.opsForValue().get("parent-child-test");
        System.out.println(value); // print:Student(sName=child name), but I wish it print Student(id=111111111,name=parent name,sName=child name)
    }

但是：Test result image

Answer 1

解决方案一:在智利类中使用Lombok.annotation @ToString(callSuper = true)；

解决方案二:将父类属性转换为子类属性；

Answer 2

您需要使用Serializable实现这两个类，并像这样定义serialVersionUID

public class People implements Serializable {

private static final long serialVersionUID = 7156526077883281623L;

}
