1、创建java web程序，加入jar文件

2、编写bean.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:context="http://www.springframework.org/schema/context"
xmlns:aop="http://www.springframework.org/schema/aop"
xmlns:tx="http://www.springframework.org/schema/tx"
xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans-2.5.xsd
http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-2.5.xsd
http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-2.5.xsd
http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-2.5.xsd">

</beans>

3、编写配置

<context:annotation-config/>

<bean id="sessionFactory" class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">
<property name="dataSource" ref="dataSource"/>
<property name="mappingResources">
<list>
<value>cn/itcast/bean/Person.hbm.xml</value>
</list>
</property>
<property name="hibernateProperties">
<value>
hibernate.dialect=org.hibernate.dialect.MySQL5Dialect
hibernate.hbm2ddl.auto=update
hibernate.show_sql=false
hibernate.format_sql=false
hibernate.cache.use_second_level_cache=true
hibernate.cache.use_query_cache=false
hibernate.cache.provider_class=org.hibernate.cache.EhCacheProvider
</value>
</property>
</bean>

<bean id="txManager" class="org.springframework.orm.hibernate3.HibernateTransactionManager">
<property name="sessionFactory" ref="sessionFactory"/>
</bean>
<tx:annotation-driven transaction-manager="txManager"/> ---事务管理

4、编写普通类Person类。

public class Person {
private Integer id;
private String name;

public Person(){}

public Person(String name) {
this.name = name;
}

.....省略get，set方法。

5、植入对应的Person.hbm.xml

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE hibernate-mapping PUBLIC
"-//Hibernate/Hibernate Mapping DTD 3.0//EN"
"http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd">
<hibernate-mapping package="cn.itcast.bean">
<class name="Person" table="person">
<cache usage="read-write" region="cn.itcast.bean.Person"/>
<id name="id">
<generator class="native"/>
</id>
<property name="name" length="10" not-null="true"/>
</class>
</hibernate-mapping>

6、编写对应的二级缓存文件ehcache.xml

<?xml version="1.0" encoding="UTF-8"?>

<ehcache>
<diskStore path="D:\cache"/>
<defaultCache maxElementsInMemory="1000" eternal="false" overflowToDisk="true"
timeToIdleSeconds="120"
timeToLiveSeconds="180"
diskPersistent="false"
diskExpiryThreadIntervalSeconds="60"/>
<cache name="cn.itcast.bean.Person" maxElementsInMemory="100" eternal="false"
overflowToDisk="true" timeToIdleSeconds="300" timeToLiveSeconds="600" diskPersistent="false"/>
</ehcache>

7、编写struts2的配置文件，载入person对象。

<?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>

<constant name="struts.i18n.encoding" value="UTF-8"/>

<constant name="struts.action.extension" value="do"/>

<constant name="struts.serve.static.browserCache" value="false"/>

<constant name="struts.configuration.xml.reload" value="true"/>

<constant name="struts.devMode" value="true" />

<constant name="struts.ui.theme" value="simple" />
<constant name="struts.objectFactory" value="spring" />

<package name="person" namespace="/person" extends="struts-default">
<global-results>
<result name="message">/WEB-INF/page/message.jsp</result>
</global-results>
<action name="action_*" class="personList" method="{1}">
<result name="list">/WEB-INF/page/personlist.jsp</result>
<result name="add">/WEB-INF/page/addperson.jsp</result>
</action>
</package>
</struts>

8、编写业务类

public interface PersonService {
public void save(Person person);
public void update(Person person);
public Person getPerson(Integer personid);
public void delete(Integer personid);
public List<Person> getPersons();
}

9、编写实现类

package cn.itcast.service.impl;
import java.util.List;
import javax.annotation.Resource;
import org.hibernate.SessionFactory;
import org.springframework.transaction.annotation.Propagation;
import org.springframework.transaction.annotation.Transactional;
import cn.itcast.bean.Person;
import cn.itcast.service.PersonService;

@Transactional
public class PersonServiceBean implements PersonService {
@Resource private SessionFactory sessionFactory;

public void save(Person person){
sessionFactory.getCurrentSession().persist(person);
}

public void update(Person person){
sessionFactory.getCurrentSession().merge(person);
}
@Transactional(propagation=Propagation.NOT_SUPPORTED,readOnly=true)
public Person getPerson(Integer personid){
return (Person)sessionFactory.getCurrentSession().get(Person.class, personid);
}

public void delete(Integer personid){
sessionFactory.getCurrentSession().delete(
sessionFactory.getCurrentSession().load(Person.class, personid));
}
@Transactional(propagation=Propagation.NOT_SUPPORTED,readOnly=true)
@SuppressWarnings("unchecked")
public List<Person> getPersons(){
return sessionFactory.getCurrentSession().createQuery("from Person").list();
}
}

10、编写web.xml文件

<?xml version="1.0" encoding="UTF-8"?>
<web-app version="2.4"
xmlns="http://java.sun.com/xml/ns/j2ee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee
http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd">
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:beans.xml</param-value>
</context-param>

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

<filter>
<filter-name>struts2</filter-name>
<filter-class>org.apache.struts2.dispatcher.FilterDispatcher</filter-class>
</filter>
<filter-mapping>
<filter-name>struts2</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
<filter>
<filter-name>OpenSessionInViewFilter</filter-name>
<filter-class>org.springframework.orm.hibernate3.support.OpenSessionInViewFilter</filter-class>
</filter>
<filter-mapping>
<filter-name>OpenSessionInViewFilter</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
<welcome-file-list>
<welcome-file>index.jsp</welcome-file>
</welcome-file-list>
</web-app>

10、编写PersonAction类

package cn.itcast.web;
import java.util.List;
import javax.annotation.Resource;
import cn.itcast.bean.Person;
import cn.itcast.service.PersonService;

public class PersonAction {
@Resource PersonService personService;
private String message;
private List<Person> persons;
private Person person;

public Person getPerson() {
return person;
}
public void setPerson(Person person) {
this.person = person;
}
/**
* 人员列表显示
*/
public String list(){
this.persons = personService.getPersons();
return "list";
}
/**
* 人员添加界面
*/
public String addUI(){
return "add";
}
/**
* 人员添加
*/
public String add(){
this.personService.save(this.person);
this.message="添加成功";
return "message";
}
public List<Person> getPersons() {
return persons;
}

public void setPersons(List<Person> persons) {
this.persons = persons;
}

public String getMessage() {
return message;
}

public void setMessage(String message) {
this.message = message;
}
}

11、编写personlist.jsp

<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>
<%@ taglib uri="/struts-tags" prefix="s"%>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
<head>
<title>人员列表</title>
</head>

<body>
<s:iterator value="persons">
id=<s:property value="id"/>,name=<s:property value="name"/><br>
</s:iterator>
</body>
</html>

12、编写message.jsp

<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>
<%@ taglib uri="/struts-tags" prefix="s"%>

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
<head>
<title>My message page</title>
</head>

<body>
<s:property value="message"/> <br>
</body>
</html>

13、编写addperson.jsp

<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>
<%@ taglib uri="/struts-tags" prefix="s"%>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
<head>
<title>人员添加</title>
</head>

<body>
<s:form action="action_add" namespace="/person">
名称:<s:textfield name="person.name"/>
