redis client 2.0.0 pipeline 的list的rpop bug，redisrpop

描述:

redis client 2.0.0 pipeline 的list的rpop 存在嚴重bug,rpop list的時候,如果list已經為空白的時候,rpop出來的Response依然不為null,導致吊response.get()方法拋異常

代碼:

@Testpublic void testRedisPipeline(){    Jedis jedis = null;    try{        jedis = new Jedis("127.0.0.1",6379);        Pipeline pipelined = jedis.pipelined();        for(int i=200;i<10000;i++){            pipelined.lpush("aa", "val"+i);        }        pipelined.sync();            }catch(Exception e){        e.printStackTrace();    }finally{        if(jedis!=null){            jedis.disconnect();        }    }}

<span style="white-space:pre"></span>//這個方法會造成redis qps無限上升@Testpublic void testRedisPipelinePop(){    Jedis jedis = null;    try{        List<Response<String>> result = new ArrayList<Response<String>>();        jedis = new Jedis("127.0.0.1",6379);        Pipeline pipelined = jedis.pipelined();        for(int i=0;i<10;i++){            //System.out.println(i);            Response<String> rpop = pipelined.rpop("aa");            //System.out.println(rpop);            result.add(rpop);        }        pipelined.sync();        //Response<Long> r = pipelined.bitcount("aa");        for (Response<String> response : result) {                System.out.println(response.get());//異常            }            }catch(Exception e){        e.printStackTrace();    }finally{        if(jedis!=null){            jedis.disconnect();        }    }}

解決方案:

使用redis-cli 2.1.0以上版本
