使用Spring Boot的redis中的嵌套键

@Autowired
private RedisTemplate<String, Object> redisTemplate;

public void saveUser(User user) {
    String key = "user:" + user.getId();
    redisTemplate.opsForHash().put(key, "name", user.getName());
    redisTemplate.opsForHash().put(key, "age", user.getAge());
    redisTemplate.opsForHash().put(key, "address", user.getAddress());
}

public User getUser(String userId) {
    String key = "user:" + userId;
    Map<Object, Object> userMap = redisTemplate.opsForHash().entries(key);

    User user = new User();
    user.setId(userId);
    user.setName((String) userMap.get("name"));
    user.setAge((Integer) userMap.get("age"));
    user.setAddress((String) userMap.get("address"));

    return user;
}
