学习小项目--学生信息管理系统用ssh2完善数据库用的是mysql

前些天做了个学生信息的管理系统 无非是些信息的增删改查 ?这次用了ssh2不用模拟数据库了

注意点：

1.jar包

2.applicationContext.xml ?struts.xml ?hibernate.cfg.xml ?mode中类和映射文件User.hbm.xml

3.配置稍稍有点不同 ?

用hibernateTemplate配置了sessionFactory在dao中配置了hibernateTemplate ?也可以直接配置seesionFactory

?

4.在struts.xml中配置action 中的class必须和对应在applicationContext.xml的<bean id="***Action" encoding="UTF-8"?><!DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN 2.0//EN" "http://www.springframework.org/dtd/spring-beans-2.0.dtd"><beans><bean id="userAction" scope="prototype"><property name="userService" ref="userService"></property></bean><bean id="userService" ref="userDAO"></property></bean><bean id="userDAO" ref="hibernateTemplate"></property></bean><bean id="hibernateTemplate" ref="sessionFactory"></property></bean><bean id="sessionFactory" value="classpath:hibernate.cfg.xml"></property></bean><!-- 负责开启、提交事务 --><bean id="transactionManager" ref="sessionFactory"></property></bean><bean id="transactionInterceptor" ref="transactionManager"></property><property name="transactionAttributes"><props><prop key="*">PROPAGATION_REQUIRED</prop></props></property></bean><bean id="autoproxy" value="*Service"></property><property name="interceptorNames" value="transactionInterceptor"></property></bean></beans>

?struts

?dao?
?action ?中部分代码是老师的：
