有个表的数据需初始化到redis, 目前18w+, 后期会达到千万

 

 

 

 

 

 

1. 使用redisTemplate批量存储数据

 

    @Autowired
    private RedisTemplate redisTemplate;

    public void init(){
        List<WxPois> list = SpringUtils.getBean(WxPoisMapper.class).selectWxPoisList(new WxPois());
        if (CollectionUtils.isEmpty(list)) {
            return;
        }
        redisTemplate.executePipelined(new RedisCallback<String>() {
            @Override
            public String doInRedis(RedisConnection connection) throws DataAccessException {
                for (WxPois wxPois : list) {
                    redisTemplate.opsForValue().set("pois:"+wxPois.getId(),wxPois);
                }
                return null;
            }
        });
        log.info("初始化客源成功");
    }

 

执行结果

20:33:48.029 [restartedMain] DEBUG c.r.r.p.m.W.selectWxPoisList - [debug,137] - <==      Total: 182935
20:34:13.498 [restartedMain] INFO  c.r.r.init.InitData - [init,42] - 初始化客源成功
