struts2和hibernate的配置我这里就不多说了,先把两个有关的东西说下。一个是所有的包。struts2+hibernate3+spring2.5我包准备放上去给大家下载。
放在的我百度云盘里面
闲话不说:开始。
先是struts2和hibernate的配置
web.xml:
<?xml version= "1.0" encoding= "UTF-8" ?> 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>
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> |
别忘了:在applicationContext.xml中配置一个bean,在xml中增加如下代码:
<!-- 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> |
运行main方法后
控制台出现:Hello:你;u is in 温州市 ; and u is 李
下面开始整合
整合struts2
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> |
整合Hibernate
Spring整合Hibernate主要是对hibernate的Session进行管理,包含Session的创建、提交、关闭的整个生命周期。Spring对事务的管理应用了AOP的技术
1) 配置sessionFactory,让spring来创建Session。
我们原来是用HibernateSessionFactory.java来创建Session的,现在删除即可,交给Spring创建。(这样就spring来整合hibernate来创建session)
这里,创建了一个Session工厂类的Bean,其ID为“sessionFactory”.
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</value> </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层调用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调用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
下面是整合下载的例子。
