spring - 如何将 hashmap 添加到 Redis 中？

Question

我在我的 Spring-data-redis 项目中使用 Redis。我正在尝试将 HashMap 插入 Redis，但找不到相应的 API？

public class EmployeeRepositoryImpl {
private static final String KEY = "Employee";

private RedisTemplate<String, Object> redisTemplate;
private HashOperations hashOperations;

@Autowired
public EmployeeRepositoryImpl(RedisTemplate<String, Object> redisTemplate){
    this.redisTemplate = redisTemplate;
}

@PostConstruct
private void init(){
    hashOperations = redisTemplate.opsForHash();
}

public void add(HashMap<Integer, Employee> employees) {
    hashOperations.put(KEY, employees);
}

}
