急求解测试 testqueryByIdWithSeckill 的问题

Question

//报错 java.lang.NullPointerException

package org.seckill.dao;

import org.junit.Test;
import org.junit.runner.RunWith;
import org.seckill.entity.Seckill;
import org.seckill.entity.SuccessKilled;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration({"classpath:spring/spring-dao.xml"})
public class SucessKilledDaoTest {

@Autowired
private SuccessKilledDao successKilledDao;

@Test
public void testinsertSuccessKilledDao() {
    /*
     * 第一次执行   insertCount:1
     * 第二次执行   insertCount:0
     * 第三次执行   insertCount:0
     * 说明什么？ 一个userid只可以秒杀一次，不可以重复秒杀QAQ
     */
    long itemid = 1000L;
    long userid = 2013002L;
    int insertCount = successKilledDao.insertSuccessKilled(itemid, userid);
    System.out.println("insertCount:" + insertCount);
}

@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());
}
