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
