练习redis--保存为hash

Person person = new Person(); 
person.setName("zhangsan"); 
person.setAge(18);

ObjectMapper objectMapper = new ObjectMapper();
//实体类转map使用jackson2HashMapper，需要一个ObjectMapper，所以实例化一个
Jackson2HashMapper jackson2HashMapper = new Jackson2HashMapper(objectMapper, false);
//实体类转Map
Map<String, Object> map = jackson2HashMapper.toHash(person);

//重写序列化器
stringRedisTemplate.setHashValueSerializer(new Jackson2JsonRedisSerializer<Object>(Object.class));

//缓存数据
stringRedisTemplate.opsForHash().putAll("zs",map);

//读取缓存数据
Map zs = stringRedisTemplate.opsForHash().entries("zs");

//map转实体
Person p = objectMapper.convertValue(zs, Person.class);

System.out.println(p.toString());
