本次环境选择：JDK1.6+MySQL数据库+C3P0连接池+（struts2，spring3，hibernate3）
首先，创建WEB工程
然后倒入相关jar包（maven项目，在pom.xml中导入坐标）
首先配置web.xml文件
1 ，Spring的监听器
|
<!--spring配置文件的加载的监听 器--> <context-param> <param-name>contextConfigLocation</param-name> <param-value>classpath:applicationContext.xml</param-value> </context-param> <listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> |
2，配置Struts2的过滤器
|
<!--3.struts2核心控制器--> <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> |
其次：在web.xml中可配置前端编码过滤器，以及hibernate的加载方式
|
<!--CharacterEncodingFilter进行编码过滤--> <filter> <filter-name>characterEncodingFilter</filter-name> <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class> </filter> <filter-mapping> <filter-name>characterEncodingFilter</filter-name> <url-pattern>/*</url-pattern> </filter-mapping> |
|
<!--2.懒加载 OpenSessionInviewFilter--> <filter> <filter-name>openSessionInViewFilter</filter-name> <filter-class>org.springframework.orm.hibernate3.support.OpenSessionInViewFilter</filter-class> <init-param> <param-name>singleSession</param-name> <param-value>true</param-value> </init-param> <init-param> <param-name>sessionFactoryBeanName</param-name> <param-value>sessionFactory</param-value> </init-param> </filter> <filter-mapping> <filter-name>openSessionInViewFilter</filter-name> <url-pattern>/*</url-pattern> </filter-mapping> |
接下来配置struts2，hibernate，spring的配置文件
struts.xml
|
<?xml version="1.0" encoding="UTF-8" ?> <!DOCTYPE struts PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 2.3//EN" "http://struts.apache.org/dtds/struts-2.3.dtd"> <struts> <constant name="struts.ui.theme" value="simple"/> <constant name="struts.devMode" value="true" /> <constant name="struts.i18n.encoding" value="UTF-8" /> <package name="default" namespace="/" extends="struts-default"> <action name="testAction" method="test" class="cn.dvt.action.TestAvtion"> <result name="success">/WEB-INF/test.jsp</result> </action> </package> </struts> |
hibernate.cfg.xml
|
<?xml version='1.0' encoding='UTF-8'?> <!DOCTYPE hibernate-configuration PUBLIC "-//Hibernate/Hibernate Configuration DTD 3.0//EN" "http://www.hibernate.org/dtd/hibernate-configuration-3.0.dtd"> <hibernate-configuration> <session-factory> <property name="dialect"> org.hibernate.dialect.MySQLDialect </property> <property name="show_sql">true</property> <property name="format_sql">false</property> <property name="hbm2ddl.auto">update</property> <!-- 懒加载，配合web.xml中配置的 openSessionInViewFilter --> <property name="hibernate.enable_lazy_load_no_trans">true</property> <!--hibernate映射文件的校验模式--> <property name="javax.persistence.validation.mode">none</property> <mapping resource="cn/dvt/domain/User.hbm.xml"></mapping> </session-factory> </hibernate-configuration> |
hibernate的po映射文件
xxx.hbm.xml
|
<?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD 3.0//EN" "http://www.hibernate.org/dtd/hibernate-mapping-3.0.dtd"> <hibernate-mapping package="cn.dvt.domain"> <class name="User" table="T_USER"> <id name="id" column="ID"> <generator class="uuid"></generator> </id> <property name="name" column="NAME"></property> <property name="age" column="AGE"></property> </class> </hibernate-mapping> |
Spring文件
applicationContext.xml
|
<?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:p="http://www.springframework.org/schema/p" xmlns:context="http://www.springframework.org/schema/context" xmlns:tx="http://www.springframework.org/schema/tx" xmlns:aop="http://www.springframework.org/schema/aop" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-3.0.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-3.0.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd"> <!--1.数据源--> <bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource"> <property name="driverClass" value="com.mysql.jdbc.Driver"></property> <property name="jdbcUrl" value="jdbc:mysql://127.0.0.1:3306/dvt?characterEncoding=utf8"></property> <property name="user" value="root"></property> <property name="password" value="admin"></property> </bean> <!--2.SessionFactory--> <bean id="sessionFactory" class="org.springframework.orm.hibernate3.LocalSessionFactoryBean"> <property name="dataSource" ref="dataSource"></property> <property name="configLocation" value="classpath:hibernate.cfg.xml"></property> </bean> <!--3.事务管理器--> <bean id="transactionManager" class="org.springframework.orm.hibernate3.HibernateTransactionManager"> <property name="sessionFactory" ref="sessionFactory"></property> </bean> <!--4.事务通知--> <tx:advice id="txAdvice" transaction-manager="transactionManager"> <tx:attributes> <tx:method name="save*" propagation="REQUIRED"></tx:method> <tx:method name="update*" propagation="REQUIRED"></tx:method> <tx:method name="delete*" propagation="REQUIRED"></tx:method> <tx:method name="find*" read-only="true"></tx:method> <tx:method name="*" propagation="REQUIRED"></tx:method> </tx:attributes> </tx:advice> <!--5.aop切面--> <aop:config> <aop:pointcut expression="execution(* cn.dvt.service.impl.*.*(..))" id="myPointCut"></aop:pointcut> <aop:advisor advice-ref="txAdvice" pointcut-ref="myPointCut"></aop:advisor> </aop:config> <!--6.DAO--> <bean id="userDao" class="cn.dvt.dao.impl.UserDaoImpl"> <property name="sessionFactory" ref="sessionFactory"></property> </bean> <import resource="classpath:spring/applicationContext-action.xml"></import> <import resource="classpath:spring/applicationContext-service.xml"></import> </beans> |
Struts2在Spring配置文件中配置时 ， 一定要注意声明“多例”scope = “prototype”
原因：Spring自身为多例，而struts2是多实例的基于filter。
