以上Dao的方法已經(jīng)正常。
對(duì)此方法的測(cè)試，我是在后期補(bǔ)上的。但是居然報(bào)錯(cuò)。幫我看看：
Junit4:(不用繼承TestCase)
public class TestDrawDao{
private DrawDao drawDao;
@Before
public void setUp(){
drawDao = new DrawDao();
}
/**
* 測(cè)試'卡領(lǐng)用申請(qǐng)信息的添加'
*/
@Test
public void testInsertDraw(){
Carddrawapply draw = new Carddrawapply();
draw.setApplyoperid(1);
draw.setApplydesc("申請(qǐng)說明");
List<Carddrawapplydetail> drawdetailList = new ArrayList<Carddrawapplydetail>();
//IC卡，100元面值的100張
Carddrawapplydetail drawdetail1 = new Carddrawapplydetail();
drawdetail1.setCardtype("1");
drawdetail1.setParvalue(100);
drawdetail1.setAmount(100);
//充值卡，50元面值的50張
Carddrawapplydetail drawdetail2 = new Carddrawapplydetail();
drawdetail2.setCardtype("2");
drawdetail2.setParvalue(50);
drawdetail2.setAmount(50);
drawdetailList.add(drawdetail1);
drawdetailList.add(drawdetail2);
boolean flag = drawDao.insertDraw(draw, drawdetailList);
//斷言
Assert.assertEquals(true,flag);
}
}
異常如下:
java.lang.NullPointerException
at org.springframework.orm.hibernate3.support.HibernateDaoSupport.getSession(HibernateDaoSupport.java:142)
at com.htdz.card.admin.dao.DrawDao.insertDraw(DrawDao.java:35)
也就是調(diào)用到DrawDao里insertDraw()的這句時(shí)報(bào)錯(cuò)：session = this.getSession();
業(yè)務(wù)類里調(diào)用這個(gè)Dao都能正常使用，為什么從測(cè)試類里調(diào)用就報(bào)這個(gè)錯(cuò)誤？
DrawDao繼承了HibernateDaoSupport了啊。
