DaoImp.java

package com.zcq.dao;

import org.springframework.orm.hibernate3.support.HibernateDaoSupport;

public class DaoImp extends HibernateDaoSupport {
	public void insert(Zcqbb as)
	{
		this.getSession().save(as);
		this.getSession().beginTransaction().commit();
	}

}

Test.java

package com.zcq.dao;

import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;

 

public class Test {
	
	public static void main(String[] args) {
		
		ApplicationContext ctx=null;
		ctx=new ClassPathXmlApplicationContext("applicationContext.xml");
		DaoImp dao=(DaoImp) ctx.getBean("daoimp");
		 Zcqbb bb=new Zcqbb();
		 
		 bb.setUsername("zcq");
		 bb.setPassword("zz");
		dao.insert(bb);
	}
}

有什么异常或者错误的提示,贴出来!

[burningice44]

<id name="id" type="java.lang.Long">
<column name="ID" precision="22" scale="0" />
<generator class="increment" />
</id>

上面代码中，如果你的主键id是自动生成的，那么在<generator class="increment" />处
应该配置上你建立的序列。要不id插入不了，就会出错。

谢谢你们 我解决了 呵呵】】】



修改
public void insert(Zcqbb as)
{
Session session=this.getSession();
session.save(as);
session.beginTransaction().commit();

}

就OK了

[M_song]

恩,ok就行,但你知道原因么?
这样写就是在同一个session中!

其实先前你那是属于事务未提交!

[zcqzcq]

我的那个session 关闭 就直接写在那个dao里 没什么问题吧？？

[M_song]

恩,可以的!

 public void insert(User user)
    {
        Session session=sessionFactory.openSession();
        Transaction tx=session.beginTransaction();
        session.save(user);
        tx.commit();
        session.close();
    }
