Answer 1

DAO里的
public String findbyId(final String hf) {
// TODO Auto-generated method stub

return (String) super.getHibernateTemplate().execute(new HibernateCallback(){
public Object doInHibernate(Session arg0) {
String sql="SELECT articleIdId FROM ArticleId AS ar WHERE ar.articleIdName =:hf";

System.out.println("sql语句返回的num：========="+arg0.createQuery(sql)
.setString("hf", hf)
.uniqueResult());

String num =(String)arg0.createQuery(sql)
.setParameter("hf", hf)
.uniqueResult();

return num;
}
});
}
public Integer findbyintName(final String name) {
// TODO Auto-generated method stub
return (Integer) super.getHibernateTemplate().execute(new HibernateCallback(){
public Object doInHibernate(Session arg0) {
System.out.println("进入来integer");
String sql="SELECT articleIdId FROM ArticleId AS ar WHERE ar.articleIdName =:name";

System.out.println("Integer：========="+arg0.createQuery(sql)
.setString("name", name)
.uniqueResult());

int num =(Integer)arg0.createQuery(sql)
.setString("name", name)
.uniqueResult();

return num;
}
});
}

Answer 2

我知道你进了,但是你看"MainAction.java:140"
是不是140行的那个方法找不到

Answer 3

140行是这个，他前面的 ==========-========= 都没有打印出来呢，这个错误不是action里的
是在dao里面，如果 我在System.out.println("==========-==========");里的
                Integer jhh = articleIdBiz.findbyintName(aid.getArticleIdName());
方法换成public String findbyId(final String hf）在add的时候转换integer.p的时候 会报错System.out.println("看看jh是否有返回件号ID："+jhh+"==也要看看有没有:"+aid.getArticleIdName());

Answer 4

这个if里换了下语句
if(jh == null){//判断是否有这个件号；
System.out.println("判断是否给予外键件号:"+aid);
articleIdBiz.addIArticle(aid);//如果没有这个件号系统就会添加这个件号
System.out.println("==========-==========");
String jhh = articleIdBiz.findbyId(aid.getArticleIdName());
//String jhh= articleIdBiz.findbyId(aid.getArticleIdName());
System.out.println("==========-==========");
System.out.println("看看jh是否有返回件号ID："+jhh+"==也要看看有没有:"+aid.getArticleIdName());
System.out.println(jhh);
hd.setArticleId(Integer.parseInt(jhh));//然后在把这个件号给hd的外键给予联系
}else{//如果有返回件号的id给Hmain上的外键赋值
hd.setArticleId(Integer.parseInt(articleIdBiz.findbyId(aid.getArticleIdName())));
}

sql语句返回的num：=========26
Hibernate: select articleid0_.articleId_Id as col_0_0_ from hdData.dbo.articleId articleid0_ where articleid0_.articleId_Name=?
