hibernate中查询出int值后为何显示不出来。

代码如下
try {
s.beginTransaction();

String hql = "from Car a "+
"where a.id=? ";

List carlist = s.createQuery(hql)
.setInteger(0, 101)
.list();

StringBuffer sb = new StringBuffer();
for(Car car1 : (List)carlist){
sb.append(car1.getId() + ":");
sb.append(car1.getType()+"\n");
}

System.out.println(sb.toString());

log4j:WARN No appenders could be found for logger (org.hibernate.cfg.Environment).

Hibernate: select car0_.OID as OID0_, car0_.ID as ID0_, car0_.MAKE as MAKE0_, car0_.TYPE as TYPE0_, car0_.COL as COL0_ from t_car car0_ where car0_.OID=?
--------------------------------
请问为什么无法显示查询结果？

你把Hibernate的语句稍微改改到mysql中执行（car0_.OID=101）看有没有结果，如果有

lazy="false" 试试。你的事务只有开始，怎么没有见到提交呢？

 string sql = "select count(*) as count from orderform";

然后就像平常取字段值一样，取count字段值就行了

代码好像没什么明显错误，先看看数据库里有没有ID是101的记录。
