RedisTemplate set方法疑问

请参考：
使用：redisTemplate.opsForValue().set("name","tom",10, TimeUnit.SECONDS);
结果：redisTemplate.opsForValue().get("name")由于设置的是10秒失效，十秒之内查询有结果，十秒之后返回为null

RedisTemplate中有一个execute方法，如下图：

 @Override
    public Object execute(String command, byte[]... args) {
        Assert.hasText(command, "a valid command needs to be specified");
        try {
            List<byte[]> mArgs = new ArrayList<>();
            if (!ObjectUtils.isEmpty(args)) {
                Collections.addAll(mArgs, args);
            }

            ReflectionUtils.invokeMethod(SEND_COMMAND, client, Command.valueOf(command.trim().toUpperCase()),
                    mArgs.toArray(new byte[mArgs.size()][]));
            if (isQueueing() || isPipelined()) {
                Object target = (isPipelined() ? pipeline : transaction);
                @SuppressWarnings("unchecked")
                Response<Object> result = (Response<Object>) ReflectionUtils.invokeMethod(GET_RESPONSE, target,
                        new Builder<Object>() {
                            public Object build(Object data) {
                                return data;
                            }

                            public String toString() {
                                return "Object";
                            }
                        });
                if (isPipelined()) {
                    pipeline(newJedisResult(result));
                } else {
                    transaction(newJedisResult(result));
                }
                return null;
            }
            return client.getOne();
        } catch (Exception ex) {
            throw convertJedisAccessException(ex);
        }
    }

底层利用了反射原理去间接调用redis.clients.jedis.Client的set方法，在去调用redis.clients.jedis.BinaryClient 的sendCommand方法，所以如果自己要调用底层jedis的

set(final String key, final String value, final String nxxx, final String expx,
      final long time) 

我们需要对代码进行如下修改，这个是思路，我还没有测试：
代码的大概逻辑是这样

  RedisTemplate<String, String> template = new StringRedisTemplate(new JedisConnectionFactory());
        template.execute(new RedisCallback<Object>() {

            @Override
            public Object doInRedis(RedisConnection connection) throws DataAccessException {
                return connection.execute("set", new byte[][]{
                        SafeEncoder.encode("key"), SafeEncoder.encode("value"), SafeEncoder.encode("nxxx"),
                        SafeEncoder.encode("expx"), Protocol.toByteArray(10)});
            }
        });

请参考我的github项目:
https://github.com/xiaohu-liu/springboot-app/edit/master/redis-test/src/test/java/com/indi/spring/redis/RedisTest.java

 package com.indi.spring.redis;


import com.indi.spring.redis.mapper.impl.RedisServiceImpl;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.context.SpringBootTest;

import org.springframework.test.context.web.WebAppConfiguration;

@RunWith(SpringJUnit4ClassRunner.class)
@SpringBootTest(classes = App.class)
@WebAppConfiguration
public class RedisTest {

    @Autowired
    private RedisServiceImpl redisService;


    @Test
    public void test1() {
        redisService.set("name", "xiaohu-liu");
        redisService.set("nickname2", "xiaohu-liu", "NX", "EX", 10);
    }


}

stringRedisTemplate.opsForValue().set(key, value);
stringRedisTemplate.expire(key,expires,tu);

expires是时间数值 tu是单位（TimeUnit），时分秒等，这个是设个存留时间，比如，缓存两小时
还可以设置到期时间，比如，设置今天晚上十点失效
public Boolean expire(K key, final long timeout, final TimeUnit unit) {
final byte[] rawKey = rawKey(key);
final long rawTimeout = TimeoutUtils.toMillis(timeout, unit);

    return execute(new RedisCallback<Boolean>() {

        public Boolean doInRedis(RedisConnection connection) {
            try {
                return connection.pExpire(rawKey, rawTimeout);
            } catch (Exception e) {
                // Driver may not support pExpire or we may be running on Redis 2.4
                return connection.expire(rawKey, TimeoutUtils.toSeconds(timeout, unit));
            }
        }
    }, true);
}

public Boolean expireAt(K key, final Date date) {
    final byte[] rawKey = rawKey(key);

    return execute(new RedisCallback<Boolean>() {

        public Boolean doInRedis(RedisConnection connection) {
            try {
                return connection.pExpireAt(rawKey, date.getTime());
            } catch (Exception e) {
                return connection.expireAt(rawKey, date.getTime() / 1000);
            }
        }
    }, true);
}

 Boolean success = redisTemplate.execute((RedisCallback<Boolean>) connection -> {
            RedisSerializer defaultSerializer = redisTemplate.getDefaultSerializer();
            Object result = connection.set(defaultSerializer.serialize("name"),
                    defaultSerializer.serialize("my name"),
                    Expiration.from(1000, TimeUnit.SECONDS),
                    RedisStringCommands.SetOption.ifAbsent());

            return (Boolean) result;
        });
