Question

hibernate 对数据库只能查询 不能增删改。

这是添加数据的----
public class Test {
/**
* @param args
*/
public static void main(String[] args) {
// TODO Auto-generated method stub
Session session=null;
Transaction tx=null;

try {
session=new Configuration().configure().buildSessionFactory().openSession();
tx=session.beginTransaction();

Test1 test1=new Test1();
test1.setName("sdfaaa");
test1.setEmail("adfa@souhu.com");

session.save(test1);
tx.commit();
} catch (Exception e) {
if(tx!=null)
{
tx.rollback();
}
}finally{
if(session!=null&&session.isOpen())
{
session.close();
}
}

}
}

这个映射文件------
<?xml version="1.0" encoding="utf-8"?>
<!DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD 3.0//EN"
"http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd">

<param name="sequence">emp_seq</param>

</class>

Answer 1

spring配置文件错误，对事务提交那块，你估计配置成只读了，看下

追问

tx=session.beginTransaction();
Test1 test1=new Test1();
test1.setName("sdfaaa");
test1.setEmail("adfa@souhu.com");

session.save(test1);
tx.commit();
我的事务提交了啊 ！

Answer 2

保存、或删除，报什么错了呢

追问

没有报错 就是发送一条select语句 查询sequence的下个数字
