在测试的hibernate的时候一直在运行 也不提示错误 也不提示失败 一直处于运行状态 但是数据没有提交 这是一个一对多的表查询，单表查询就没有问题，多对多查询也是一样不行，整了一天了都没解决，自学的hibernate，哪位大哥帮忙解决一下 谢谢

public class HibernateDemo1 {
@Test
public void demo1() {
Session session = HibernateUtils.getCurrentSession();
Transaction tx = session.beginTransaction();
//创建一个客户
Customer customer = new Customer();
customer.setCust_name("李冰");

for(int i = 1;i<=10;i++) {
    LinkMan linkMan = new LinkMan();
    linkMan.setLkm_name("凤姐"+i);
    linkMan.setCustomer(customer);
    customer.getLinkMans().add(linkMan);
    session.save(linkMan);
}
tx.commit();
}

}
