急求解test testqueryByIdWithSeckill 報(bào)錯(cuò) java.lang.NullPointerException的問(wèn)題
我試著幾種方法解決，好像都沒(méi)用。代碼如下
@Test
?? ?public void testqueryByIdWithSeckill() {
?? ??? ?long itemid = 1000L;
?? ??? ?long userid = 2013000L;
?? ??? ?SuccessKilled seckill = successKilledDao.queryByIdWithSeckill(itemid, userid);
?? ??? ?System.out.println("seckill:" + seckill);
?? ??? ?System.out.println("*********/n" + seckill.getSeckill());
?? ?}
