先是struts2和hibernate的配置
web.xml:
<?xml version="1.0" encoding="UTF-8"?>
<web-app version="2.5" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"> <!-- structs2的配置 --> <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></web-app> 然后在src下添加一个struts.xml:
<?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE struts PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 2.0//EN" "http://struts.apache.org/dtds/struts-2.0.dtd"> <struts> </struts>
然后在src下添加一个hibernate.cfg.xml：（这是一些数据库的配置）
<?xml version='1.0' encoding='UTF-8'?>
<!DOCTYPE hibernate-configuration PUBLIC
"-//Hibernate/Hibernate Configuration DTD3.0//EN"
"http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd">
<!-- Generated by MyEclipse Hibernate Tools. -->
<hibernate-configuration>
<session-factory>
<property name="connection.username">sa</property>
<property name="connection.url">
jdbc:jtds:sqlserver://localhost:1433;DatabaseName=LQQ
</property>
<property name="dialect">
org.hibernate.dialect.SQLServerDialect
</property>
<!--<property name="myeclipse.connection.profile">
LoginSystem
</property> -->
<property name="connection.password">sa</property>
<property name="connection.driver_class">
net.sourceforge.jtds.jdbc.Driver
</property>
<property name="show_sql">true</property>
<!-- POJO 类映射配置-->
<mapping resource="sedion/xq/ORM/Stuinfo.hbm.xml" />
</session-factory>
</hibernate-configuration>
重点讲Spring：
1. 在src下面新建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" xmlns:p="http://www.springframework.org/schema/p"
xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.0.xsd">
<!-- 这是个例子待会会用到 可以先不要 -->
<bean id="TUser_id" class="test.TUser">
<property name="username" value="你"></property>
<property name="allname" value="李"></property>
<property name="address" value="温州市"></property>
</bean>
</beans>
然后在web-xml：
<context-param>
<param-name>contextConfigLocation</param-name> <!--spring 的配置文件加载路径--> <param-value>classpath:applicationContext.xml</param-value></context-param>2.Spring基本配置完毕
下面我们测试下：src建个test包
建两个类User和SpringTest类:
public class User implements java.io.Serializable {
/**
*
*/
private static final long serialVersionUID = 1L;
private String username;
private String allname;
private String address;
public String getUsername() {
return this.username;
}
public void setUsername(String username) {
this.username = username;
}
public String getAllname() {
return this.allname;
}
public void setAllname(String allname) {
this.allname = allname;
}
public String getAddress() {
return this.address;
}
public void setAddress(String address) {
this.address = address;
}
public class SpringTest {
public static void main(String[] args) { // 加载spring配置文件，初始化IoC容器 ApplicationContext ac = new ClassPathXmlApplicationContext( "applicationContext.xml"); // 从容器 接管Bean TUser user = (TUser) ac.getBean("TUser_id"); // 输出欢迎信息 System.out.println("Hello:" + user.getUsername() + ";u is in " + user.getAddress() + " ; and u is " + user.getAllname()); }}<br><br>在applicationContext.xml中配置一个bean，在xml中增加如下代码：
<!-- 这是个例子 可以先不要 -->
<bean id="TUser_id" class="test.TUser"> <property name="username" value="你"></property> <property name="allname" value="李"></property> <property name="address" value="重庆市"></property> </bean>运行main方法后
控制台出现：Hello:你;u is in 重庆市 ; and u is 李
下面开始整合
1.整合struts2配置web.xml文件。在web.xml中加入以下代码：
<!-- Spring与Struts的整合其实就是把Struts的Action类交给Spring来管理 -->
<listener> <listener-class> org.springframework.web.context.ContextLoaderListener </listener-class></listener>2.举个例子：
把struts的action交给spring：
先把
<action name="login" class="test.LoginAction ">
改为
<action name="login" class="loginAction_id">
然后在
在applicationContext.xml中增加如下代码：
<bean id="loginAction_id" class="test.action.LoginAction" scope="prototype">
</bean>
在applicationContext.xml中增加如下代码：
<!-- 配置sessionFactory -->
<bean id="sessionFactory" class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">
<property name="configLocation">
<value>classpath:hibernate.cfg.xml<![]()
alue>
</property>
</bean>
还有个例子上的配置：
<bean id="sessionFactory" class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">
<property name="configLocation">
<value>classpath:hibernate.cfg.xml<
</property>
</bean>
还有个例子上的配置：
<bean id="sessionFactory"
class="org.springframework.orm.hibernate3.LocalSessionFactoryBean"> <property name="dataSource" ref="dataSource"></property> <property name="hibernateProperties"> <props> <prop key="hibernate.dialect">org.hibernate.dialect.SQLServerDialect</prop> <prop key="hibernate.show_sql">true</prop> </props> </property> <property name="mappingResources"> <list> <value>sedion/xq/bean/User.hbm.xml</value><!--这里是将映射文件加载--> </list> </property> </bean>2.然后DAO层匹配一个session工厂，<ref bean="sessionFactory"/>这个sessionFactory是指session工厂的ID。
<bean id="userDao" class="sedion.xq.dao.iml.UserDAOImpl" scope="singleton">
<property name="sessionFactory">
<ref bean="sessionFactory" />
</property>
</bean>
3.service层注入DAO层
<bean id="userService" class="sedion.xq.sevice.iml.UserServiceImpl">
<property name="userDAO" ref="userDao"></property>
</bean>
然后就是各个action注入service层：（随便写个）
<bean id="saveUesrAction" class="sedion.xq.action.user.SaveUserAction"
scope="prototype">
<property name="userService" ref="userService"></property>
</bean>
整合就这样好
