调用redisTemplate的executePipelined方法，传入RedisCallback实现，要跟redis沟通的命令都写在这实现里，代表一次pipeline。
注意：此时的RedisCallback返回值必须为null，可以看源码，很简单
StringRedisSerializer stringRedisSerializer = new StringRedisSerializer();
redisTemplate.executePipelined((RedisCallback<Object>) connection -> {
for (int j = 0; j < 1000; j++) {
byte[] rawKey = stringRedisSerializer.serialize("books");
byte[] rawValue = stringRedisSerializer.serialize(j + "");
connection.zIncrBy(rawKey, 10000L, rawValue);
}
return null;
});
