executSeckill测试问题？

@Test
public void executeSeckill() throws Exception {
   long id = 1000;
   long phone = 13877093290L;
   String  md5 = "42d56fec120bf23e3af750569ca017c3";
   SeckillExcution seckillExcution = seckillService.executeSeckill(id,phone,md5);
   logger.info("SeckillExcution={}"+seckillExcution);

输出结果
