1、mapper是这样的。在网上没有查到insert ignore into对应的oracle写法，暂时这样写了。

<insert id="insertSuccessKilled">

insert into success_killed(seckill_id,user_phone)

values (#{seckillId}, #{userPhone})

</insert>

2、报错信息是这样的，Error getting generated key or setting result to parameter object. Cause: java.lang.NullPointerException
