错误这样

用的code

Pipeline p = jedis.pipelined();
Response<String> omObj = p.hget("om.ctr", "rekoe");
omObj.get();

要先执行pipeline.multi(),然后才能取值

另外,集群不支持pipeline,分片也不支持pipeline的

每次 omObj.get(); 前调用 还是 jedis.pipelined() 后调用一次

两者都没用

omObj.get() 之前仅调用一次

Pipeline p = jedis.pipelined();

			for (String id : ids) {
				Response<String> omObj = p.hget("om.ctr", id);
				p.multi();
				long number = Castors.me().castTo(omObj.get(), long.class);
				p.hset("om.ctr", id, (number + 1) + "");
			}
			p.sync();

还是提示这个错误

完全错误啦... pipeline是收集全部操作,然后发送给服务器,然后全部取回结果.

                        Pipeline p = jedis.pipelined();
                        List<Response<String>> resps = new ArrayList<>();
			for (String id : ids) {
				Response<String> omObj = p.hget("om.ctr", id);
				resps.add(omObj);
			}
			p.sync();
			for (Response<String> resp : resps) {
				long number = Castors.me().castTo(omObj.get(), long.class);
				jedis.hset("om.ctr", id, (number + 1) + "");
                        }

再说了, 你需要的是hincr, 并不需要hget+hset

我是需要统计一堆id的累加值
