Answer 1

application.xml中的MyuserDAOProxy，你的信息不够

Answer 2

这个问题困扰我几天了，如果能够解决真是太感谢了！！！！！applicationContext.xml文件：<?xml version="1.0" encoding="UTF-8"?>
<beans
xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.0.xsd">
<bean id="sessionFactory"
class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">
<property name="configLocation"
value="classpath:hibernate.cfg.xml">
</property>
</bean>


<bean id="man" name="man_name" class="springtest.Man">
<property name="massage">
<value>お疲れ様です！劉さん。</value>
</property>
</bean>

<bean id="MyuserDAO" class="springdao.MyuserDAO">
<property name="sessionFactory">
<ref bean="sessionFactory" />
</property>
</bean>
<bean id="transactionManager"
class="org.springframework.orm.hibernate3.HibernateTransactionManager">
<property name="sessionFactory">

</property>
</bean>


<bean id="MyuserDAOProxy"

</property>
<property name="transactionManager">

<property name="target">

</property>
<property name="transactionAttributes">

</bean>

</beans>

Answer 3

MyuserDAO,你的名字不要这么写，所有的bean id要小写开头
at springdao.SpringDAOTest.main(SpringDAOTest.java:14) 
Caused by: net.sf.cglib.core.CodeGenerationException: java.lang.reflect.InvocationTargetException-->null
反正是没找到，你先改一下吧

Answer 4

还是不行啊
我再把SpringDAOTest.java文件放上来package springdao;import org.hibernate.SessionFactory;
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");

Myuser user = new Myuser();
user.setPassword("pa");
user.setUsername("spring dao");

MyuserDAO dao = (MyuserDAO)ctx.getBean("myuserDAOProxy");
dao.save(user);


}}

Answer 5

MyuserDAO dao = (MyuserDAO)ctx.getBean("myuserDAOProxy"); 
这是什么，你不是要myuserDAO么，为什么要用这个呢

Answer 6

用Spring 1.2 的事务代理类解决事务提交问题

Answer 7

MyuserDAO dao = (MyuserDAO)ctx.getBean("myuserDAOProxy"); 
不是myuserDAOProxy,是myuserDAO

Answer 8

把你MyuserDAO里的main 方法去掉试试看
另外bean id可以大写开头，不要乱说

Answer 9

跟7楼说的那样改成MyuserDAO dao = (MyuserDAO)ctx.getBean("MyuserDAO"); 
myuserDAOProxy只是做事务代理用的，真正使用的时候还是用MyuserDAO

Answer 10

是的
改成MyuserDAO dao = (MyuserDAO)ctx.getBean("MyuserDAO"); 这种做法我已经通过了。只是用Spring 1.2 的事务代理类解决事务提交问题不行
