暑假项目总结（二）

搭建SSH+JAP+MYSQL开发环境

一、严格的三层包结构，加入相应包

2.引入struts.xml,名字一定要写对否则报错。

3.引入ssh.xml,配置数据源及事务处理，将注解的实体一一添上。

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
		xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

		<context:annotation-config/>
		<context:component-scan base-package="cn.edu"/>
		<tx:annotation-driven transaction-manager="transactionManager"/>

		<bean id="mydataSource" class="org.apache.commons.dbcp.BasicDataSource">
			<property name="driverClassName" value="com.mysql.jdbc.Driver"/>
			<property name="url" value="jdbc:mysql://localhost:3306/music"/>
			<property name="username" value="root"/>
			<property name="password" value="pxj1989"/>
		</bean>	

		<bean id="mysessionFactory" class="org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean">
			<property name="dataSource" ref="mydataSource"></property>
			<property name="hibernateProperties">
				<props>
					<prop key="hibernate.dialect">
					org.hibernate.dialect.MySQLDialect
					</prop>
					<prop key="hibernate.show_sql">false</prop>
					<prop key="hibernate.format_sql">false</prop>
				</props>
			</property>
			<property name="annotatedClasses">
				<list>
					<value>cn.edu.cqu.cqzy.entity.User</value>
					<value>cn.edu.cqu.cqzy.entity.Category</value>
					<value>cn.edu.cqu.cqzy.entity.CategoryRelation</value>

					<value>cn.edu.seu.cqzy.domain.MapAudio</value>
					<value>cn.edu.seu.cqzy.domain.MapPoints</value>
				</list>
			</property>
		</bean>	

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

4.修改web.xml,添加struts2过滤器及实例化spring容器

<filter>
        <filter-name>struts2</filter-name>
        <filter-class>
            org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter</filter-class>
    </filter>
    <filter-mapping>
        <filter-name>struts2</filter-name>
        <url-pattern>/*</url-pattern>
    </filter-mapping>

    <!-- 指定spring容器配置文件位置， 利用Listener实例化spring容器 -->
    <context-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>classpath:ssh.xml</param-value>
    </context-param>

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

    <!-- 为了支持scope="request|session" -->
    <listener>
        <listener-class>
            org.springframework.web.context.request.RequestContextListener</listener-class>
    </listener>

4.合理分包，理清项目结构，struts.xml,ssh.xml也分割、引入

struts中引入其它.xml

<include file="struts-*.xml"></include>

ssh中引入其他.xml

<import resource="user_spring.xml" />
