初学ssh框架调整小项目-老师学生成绩管理系统

初学ssh框架整合小项目--老师学生成绩管理系统

前天学习了关于三个框架的整合，主要spring-hibernate-struts1，因为没学struts2所以暂时是用1做的

一个很简单的项目---老师学生成绩管理系统

先说三个框架的整合：

1.导入三个框架的jar包；

2.拷贝hibernate.cfg.xml文件到SRC目录下，拷贝spring的配置文件applicationContext.xml和struts1的配置文件放入到WEB-INF目录下 <listener>

3.在web.xml文件里加入下面这个监听器

 

  <listener>
  	<listener-class>
              org.springframework.web.context.ContextLoaderListener
        </listener-class>
  </listener>

 

 下面是我的两个spring配置文件的

这个是applicationContext_dao_service_action导入到applicationContext中

 

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN 2.0//EN" "http://www.springframework.org/dtd/spring-beans-2.0.dtd">

<beans>
	<bean name="/login" class="com.aowin.action.LoginAction">
		<property name="studentService" ref="studentService"></property>
		<property name="sysuserService" ref="sysuserService"></property>
		<property name="scoreService" ref="scoreService"></property>
	</bean>
	
	<bean id="scoreDAO" class="com.aowin.dao.imp.ScoreDAO">
		<property name="sessionFactory" ref="sessionFactory"></property>
	</bean>
	
	<bean id="studentDAO" class="com.aowin.dao.imp.StudentDAO">
		<property name="sessionFactory" ref="sessionFactory"></property>
	</bean>
	
	<bean id="sysuserDAO" class="com.aowin.dao.imp.SysuserDAO">
		<property name="sessionFactory" ref="sessionFactory"></property>
	</bean>
	
	<bean id="scoreService" class="com.aowin.service.ScoreService">
		<property name="scoreDAO" ref="scoreDAO"></property>
	</bean>
	
	<bean id="studentService" class="com.aowin.service.StudentService">
		<property name="studentDAO" ref="studentDAO"></property>
	</bean>
	
	<bean id="sysuserService" class="com.aowin.service.SysuserService">
		<property name="sysuserDAO" ref="sysuserDAO"></property>
	</bean>
</beans>

 下面是applicationContext

 

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN 2.0//EN" "http://www.springframework.org/dtd/spring-beans-2.0.dtd">

<beans>
	<import resource="applicationContext_dao_service_action.xml"/>
	
	<bean id="sessionFactory" class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">
		<property name="configLocation" value="classpath:hibernate.cfg.xml"></property>
	</bean>
	
	<bean id="transactionManager" class="org.springframework.orm.hibernate3.HibernateTransactionManager">
		<property name="sessionFactory" ref="sessionFactory"></property>
	</bean>
	
	<bean id="transactionInterceptor" class="org.springframework.transaction.interceptor.TransactionInterceptor">
		<property name="transactionManager" ref="transactionManager"></property>
		<property name="transactionAttributes">
			<props>
				<prop key="*add*">PROPAGATION_REQUIRED</prop>
				<prop key="*delete*">PROPAGATION_REQUIRED</prop>
				<prop key="*update*">PROPAGATION_REQUIRED</prop>
				<prop key="*get*">readOnly</prop>
			</props>
		</property>
	</bean>
	
	<bean id="autoProxty" class="org.springframework.aop.framework.autoproxy.BeanNameAutoProxyCreator">
		<property name="beanNames" value="*Service"></property>
		<property name="interceptorNames" value="transactionInterceptor"></property>
	</bean>
</beans>

 model类和映射的文件包括hibernate的配置文件都可以自动生成还可以用DB反向生成，这里就不放配置文件了。

注：在struts1中的配置文件路径后的type应该是

 

  <action path="/login" type="org.springframework.web.struts.DelegatingActionProxy"parameter="action">

  <forward name="success" path="/welcome.jsp"></forward>

  <forward name="fail" path="/index.jsp"></forward>

  </action>

接下来就是编写业务的代码：service主要是对业务的逻辑处理  dao层主要处理数据库 比较简单

主要还是action中
