spring 联合hibernate不能保存数据???
spring 联合hibernate不能保存数据???????????? 程序没报错
我用的数据库是mysql5.0; 高手们,帮我指点一下啊,谢谢了啊
这是我的测试代码:
package springdao;

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

public class Springdaotest {

/**
* @param args
*/
public static void main(String[] args) {
ApplicationContext ctx=
new ClassPathXmlApplicationContext("applicationContext.xml");
BbsuserDAO dao=(BbsuserDAO)ctx.getBean("BbsuserDAO");
Bbsuser user=new Bbsuser();
user.setUsername("lmbmb");
user.setPassword("12323");
System.out.println(user.getUsername());



dao.save(user);
System.out.println(user.getPassword());

}

}

这是Bbsuser.hbm.xml
<?xml version="1.0" encoding="utf-8"?>
<!DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD 3.0//EN"
"http://hibernate.
<!--

</property>
<property name="age" type="java.lang.String">

这是applicationContext.xml
