redis hash怎么用

public static void testHsh() {          System.out.println("==Hash==");          Jedis jedis = RedisUtil.getJedis();          try {              Map<String, String> pairs = new HashMap<String, String>();              pairs.put("name", "Akshi");              pairs.put("age", "2");              pairs.put("sex", "Female");              jedis.hmset("kid", pairs);              List<String> name = jedis.hmget("kid", "name");// 结果是个泛型的LIST              // jedis.hdel("kid","age"); //删除map中的某个键值              System.out.println(jedis.hmget("kid", "pwd")); // 因为删除了，所以返回的是null              System.out.println(jedis.hlen("kid")); // 返回key为user的键中存放的值的个数              System.out.println(jedis.exists("kid"));// 是否存在key为user的记录              System.out.println(jedis.hkeys("kid"));// 返回map对象中的所有key              System.out.println(jedis.hvals("kid"));// 返回map对象中的所有value                Iterator<String> iter = jedis.hkeys("kid").iterator();              while (iter.hasNext()) {                  String key = iter.next();                  System.out.println(key + ":" + jedis.hmget("kid", key));              }                List<String> values = jedis.lrange("messages", 0, -1);              values = jedis.hmget("kid", new String[] { "name", "age", "sex" });              System.out.println(values);              Set<String> setValues = jedis.zrange("hackers", 0, -1);              setValues = jedis.hkeys("kid");              System.out.println(setValues);              values = jedis.hvals("kid");              System.out.println(values);              pairs = jedis.hgetAll("kid");              System.out.println(pairs);          } catch (Exception e) {              e.printStackTrace();          } finally {              RedisUtil.getPool().returnResource(jedis);          }            // 清空数据          System.out.println(jedis.flushDB());          // 添加数据          jedis.hset("hashs", "entryKey", "entryValue");          jedis.hset("hashs", "entryKey1", "entryValue1");          jedis.hset("hashs", "entryKey2", "entryValue2");          // 判断某个值是否存在          System.out.println(jedis.hexists("hashs", "entryKey"));          // 获取指定的值          System.out.println(jedis.hget("hashs", "entryKey")); // 批量获取指定的值          System.out.println(jedis.hmget("hashs", "entryKey", "entryKey1"));          // 删除指定的值          System.out.println(jedis.hdel("hashs", "entryKey"));          // 为key中的域 field 的值加上增量 increment          System.out.println(jedis.hincrBy("hashs", "entryKey", 123l));          // 获取所有的keys          System.out.println(jedis.hkeys("hashs"));          // 获取所有的values          System.out.println(jedis.hvals("hashs"));      }
