org.springframework.data.redis.core.RedisTemplate 查一个key的哈希怎么查

Answer 1

@Test
public void queryCacheKey() throws Exception{
String key = "00000002";
String hashKey = "513117070";
//校验哈希key是否存在，存在为true,反之false
Boolean hasKey = redisTemplate.opsForHash().hasKey(key, hashKey);
System.out.println(hasKey);
if(hasKey){
//取值
Object object = redisTemplate.opsForHash().get(key, hashKey);
System.out.println("取出存储key-value:" + object.toString());
}
}
