2. 配置beans.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:context="http://www.springframework.org/schema/context"

<!--使用field方法注入依赖对象 -->
<context:annotation-config />
<!-- -->
<bean id="personService" class="cn.soldier.service.impl.PersonServiceBean"></bean>
</beans>

3.新建实体bean Person
package cn.soldier.bean;
Person.java
public class Person {
private Long id;
private String name;

public Person() {
}

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

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

public Long getId() {
return id;
}

public void setId(Long id) {
this.id = id;
}

public String getName() {
return name;
}

public void setName(String name) {
this.name = name;
}

public String toString() {
return "Person [id=" + id + " name=" + name + "]";
}

}
4.建立对应的数据库映射
Person.hbm.xml

<?xml version="1.0"?>
<!DOCTYPE hibernate-mapping PUBLIC
"-//Hibernate/Hibernate Mapping DTD 3.0//EN"
"http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd">

<hibernate-mapping package="cn.soldier.bean">

<class name="Person" table="person">
<id name="id">
<generator class="native" />
</id>
<property name="name" />
</class>
</hibernate-mapping>

5.建立访问Person实体的Service接口
package cn.soldier.service;

import java.util.List;
import cn.soldier.bean.Person;

public interface PersonService {

public abstract void save(Person person);

public abstract void update(Person person);

public abstract void delete(Long id);

public abstract Person getPerson(Long id);

public abstract List<Person> getPersons();
}

6.建立访问Person实体的Service实现方法
package cn.soldier.service.impl;

import java.util.List;

import javax.annotation.Resource;

import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.springframework.transaction.annotation.Propagation;
import org.springframework.transaction.annotation.Transactional;

import cn.soldier.bean.Person;
import cn.soldier.service.PersonService;

@Transactional //启用事务管理
public class PersonServiceBean implements PersonService {
@Resource//使用filed注入SessionFactory对象
SessionFactory sessionFactory;

public void save(Person person) {
// 得到容器里面正在被Transaction管理的Session
// 如果使用opeSession(),获得的Session对象是不受Transaction管理的。
Session session = (Session) sessionFactory.getCurrentSession();
session.persist(person);
}

public void update(Person person) {
sessionFactory.getCurrentSession().merge(person);// SaveOrUpdate
}

public void delete(Long id) {
// load方法性能最佳，因为get方法有一个数据装配的过程
sessionFactory.getCurrentSession().delete(
sessionFactory.getCurrentSession().load(Person.class, id));
}

@Transactional(propagation = Propagation.NOT_SUPPORTED, readOnly = true)// 不启用事务管理，只读
public Person getPerson(Long id) {
return (Person) sessionFactory.getCurrentSession()
.get(Person.class, id);
}
@Transactional(propagation = Propagation.NOT_SUPPORTED, readOnly = true)
@SuppressWarnings("unchecked")
// 终止警告
public List<Person> getPersons() {
return sessionFactory.getCurrentSession().createQuery("From Person").list();
}
}
7.测试开发好的PersonServiceBean
package junit.test;

import org.junit.BeforeClass;
import org.junit.Test;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;

import cn.soldier.bean.Person;
import cn.soldier.service.PersonService;

public class PersonServiceBeanTest {
private static PersonService personService;

@BeforeClass
public static void setUpBeforeClass() throws Exception {
try {
ApplicationContext ctx = new ClassPathXmlApplicationContext(
"beans.xml");
personService = (PersonService) ctx.getBean("personService");

} catch (Exception e) {
e.printStackTrace();
}
}

@Test
public void testSave() {
for (int i = 0; i <10; i++) {
Person person = new Person("逗比---"+i+"---号");
personService.save(person);
}
}

@Test
public void testUpdate() {
Person person = personService.getPerson(1L);
person.setName("逗比2号");
personService.update(person);
System.out.println(personService.getPerson(1L));
}

@Test
public void testDelete() {
personService.delete(2L);
}

@Test
public void testGetPersons() {
for (Person person : personService.getPersons()) {
System.out.println(person);
}
}
}

/************************************************以上步骤已经把Spring 和 Hibernate 集成好了，下面开始继承struts1.3********************************************************/

a.导入jar
struts-1.3.8解压目录下的所有jar，jstl-1.0.2.jar和Standard-1.0.2.jar更换为1.1版本额。
另外因为Spring中已经存在一个antlir-2.7.6.jar，所以struts中的antilr-2.7.2.jar应删除避免jar包冲突

b.配置web.xml
<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" version="2.5">
<!--在web容器中实例化Spring容器-->
<!--指定spring的配置文件，默认是从web根目录下寻找配置文件。可以通过spring提供的classpath:前缀指定从类路径下寻找 -->
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:beans.xml</param-value>
</context-param>
<!--对spring容器进行实例化 -->
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
<!--在web容器中配置struts-->
<servlet>
<!-- -->
<servlet-name>action</servlet-name>
<servlet-class>org.apache.struts.action.ActionServlet</servlet-class>
<!--指定struts的配置文件 -->
<init-param>
<param-name>config</param-name>
<param-value>/WEB-INF/struts-config.xml</param-value>
</init-param>
<load-on-startup>0</load-on-startup>
</servlet>
<!--处理所有以.do后缀的请求-->
<servlet-mapping>
<servlet-name>action</servlet-name>
<url-pattern>*.do</url-pattern>
</servlet-mapping>
<!--index-->
<welcome-file-list>
<welcome-file>index.jsp</welcome-file>
</welcome-file-list>
</web-app>

c.配置Struts-config.xml
<?xml version="1.0" encoding="utf-8" ?>
<!DOCTYPE struts-config PUBLIC
"-//Apache Software Foundation//DTD Struts Configuration 1.2//EN"
"http://struts.apache.org/dtds/struts-config_1_2.dtd">
<struts-config>
<!--配置action-->
<action-mappings>
<action path="/person/list" type="cn.soldier.web.action.PersonAction"
validate="false">
<forward name="list" path="/WEB-INF/page/personlist.jsp" />
</action>
</action-mappings>
<!--配置请求控制器-->
<controller>
<set-property property="processorClass" value="org.springframework.web.struts.DelegatingRequestProcessor" />
</controller>
</struts-config>

d.编写Action，Action要继承org.apache.struts.action.Action，并重写execute方法
package cn.soldier.web.action;

import javax.annotation.Resource;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import org.apache.struts.action.Action;
import org.apache.struts.action.ActionForm;
import org.apache.struts.action.ActionForward;
import org.apache.struts.action.ActionMapping;

import cn.soldier.service.PersonService;

public class PersonAction extends Action {

public ActionForward execute(ActionMapping mapping, ActionForm form,
HttpServletRequest request, HttpServletResponse response)
throws Exception {
/*
如果没有把action交给spring管理时，可以通过下面语句向spring获取容器实例
*/
WebApplicationContext ctx = WebApplicationContextUtils
.getWebApplicationContext(this.getServlet().getServletContext());
PersonService personService = (PersonService) ctx
.getBean("personService");
request.setAttribute("persons", personService.getPersons());
return mapping.findForward("list");
}
}
e.上面步骤好了就可以访问这个Action了
http://localhost:8080/SSH/person/list.do

f.配置把action交给spring管理
首先：配置beans.xml
<!--在struts配置文件中，添加进spring的请求控制器，该请求控制器会先根据action的path属性值到spring容器中寻找该属性名相同二代bean。如果找到该bean则处理用户请求-->
<!--将action注入业务层的bean，确保action的path属性与bean名称相同。-->
<!--例子如下：-->
<!--<action path="XXXXX" ...></action>-->
<!--<bean name="XXXXX" clas="cn.soldier.action.PersonAction" />-->

<bean name="/person/list" class=" cn.soldier.web.action.PersonAction"></bean>

然后在struts-config.xml下配置spring的求情控制器：
<controller>
<set-property value="processorClass" property="org.springframework.web.struts.DelegatingRequestProcessor"/>
</controller>

g.配置spring的二级缓存
1.首先在bean.xml配置的sessionFactory中配置开启二级缓存
<bean id="sessionFactory" class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">
<property name="dataSource" ref="dataSource" />
<property name="mappingResources">
<list><value>cn/soldier/bean/Person.hbm.xml</value></list>
</property>
<property name="hibernateProperties">
<props>
<!-- 指定数据库方言 -->
<prop key="hibernate.dialect">org.hibernate.dialect.MySQLInnoDBDialect</prop>
<!-- 是否根据需要每次自动创建数据库 -->
<prop key="hibernate.hbm2ddl.auto">update</prop>
<!-- 显示Hibernate持久化操作所生成的SQL -->
<prop key="hibernate.show_sql">true</prop>
<!-- 将SQL脚本进行格式化后再输出 -->
<prop key="hibernate.format_sql">false</prop>
<!--启用Hibernate二级缓存 -->
<prop key="hibernate.cache.use_second_level_cache">true</prop>
<!--启用query查询缓存 -->
<prop key="hibernate.cache.use_query_cache">false</prop>
<!-- 指定缓存的供应商 -->
<prop key="hibernate.cache.provider_class">org.hibernate.cache.EhCacheProvider</prop>
</props>
</property>
</bean>
2.然后配置ehCache.xml，上面指定的缓存供应商是EhCache，EhCache的配置文件默认是classpath下的ehCache.xml
<?xml version="1.0" encoding="UTF-8"?>
<ehcache>
<!--缓存对象存储路径 -->
<diskStore path="D:\temp\javawebe\cache" />
<!--defaultCache 节点为缺省的缓存策略 -->
<!--maxElementsInMemory 内存中最大允许存在的对象数量 -->
<!--eternal 设置缓存中的对象是否永不过期 -->
<!--overflowToDisk 把溢出的对象存放到硬盘上 -->
<!--timeToIdleSeconds 指定缓存对象空闲多长时间过期，过期的对象会被清除掉 -->
<!--timeToLiveSeconds 指定缓存对象总的粗活时间 -->
<!--diskPersistent 当jvm结束是否持久化对象 -->
<!--diskExpiryThreadIntervalSeconds 指定专门用于清除过期对象的监听线程轮询时间 -->
<defaultCache maxElementsInMemory="10000" eternal="false"
timeToIdleSeconds="120" timeToLiveSeconds="120" overflowToDisk="true"
diskPersistent="false" diskExpiryThreadIntervalSeconds="60" />

<cache name="sampleCache1" maxElementsInMemory="10000" eternal="false"
timeToIdleSeconds="300" timeToLiveSeconds="600" overflowToDisk="true" />

<cache name="sampleCache2" maxElementsInMemory="1000" eternal="true"
timeToIdleSeconds="0" timeToLiveSeconds="0" overflowToDisk="false" />
</ehcache>

3.配置Person.hbm.xml,指定需要使用缓存的bean的Hibernate映射文件中添加缓存配置
<?xml version="1.0"?>
<!DOCTYPE hibernate-mapping PUBLIC
"-//Hibernate/Hibernate Mapping DTD 3.0//EN"
"http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd">
<hibernate-mapping package="cn.soldier.bean">
<class name="Person" table="person">
<!--配置启用缓存 -->
<!--usage：缓存策略-->
<!--region：缓存的区域 -->
<cache usage="read-write" region="cn.soldier.bean.Person"/>
<id name="id">
<generator class="native" />
</id>
<property name="name" />
</class>
</hibernate-mapping>

4.可省略(针对某个缓存区域指定特定策略)
ehcache.xml下配置
<!--针对某个缓存区域指定特定策略 -->
<Cache name="cn.soldier.bean.Person" maxElementsInMemory="100"
eternal="false" timeToIdleSeconds="120" timeToLiveSeconds="120"
overflowToDisk="true" diskPersistent="false"diskExpiryThreadIntervalSeconds="60" />

5.可以使用了(下面是测试缓存是否启用)
PersonServiceBeanTest.java
@Test
public void testSecondLevelCache() {
System.out.println("第一次请求getPerson()");
System.out.println(personService.getPerson(1L));
//
try {
System.out.println("请关闭数据库");
Thread.sleep(1000 * 15);
} catch (InterruptedException e) {
e.printStackTrace();
}
//
System.out.println("关闭数据库后第二次请求getPerson()");
System.out.println(personService.getPerson(1L));
}

h.使用spring解决strut1.3的中文乱码问题
1.创建一个html表单 index.jap
<%@ page language="java" import="java.util.*" pageEncoding="utf-8"%>
<%@ taglib uri="http://struts.apache.org/tags-html" prefix="html"%>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
<head>
<title>Struts1.3+Sprin2.5+Hibernate3.3集成</title>
<meta http-equiv="pragma" content="no-cache">
<meta http-equiv="cache-control" content="no-cache">
<meta http-equiv="expires" content="0">
<meta http-equiv="keywords" content="keyword1,keyword2,keyword3">
<meta http-equiv="description" content="This is my page">

</head>
<body>
<html:form action="/person/manage" method="post">
名称：<html:text property="name"></html:text>
<br />
<input type="submit" value="提交" />
<input type="hidden" name="method" value="add" />
</html:form>
</body>
</html>
2.定义请求Action PersonManageAction.java
package cn.soldier.web.action;

import javax.annotation.Resource;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import org.apache.struts.action.ActionForm;
import org.apache.struts.action.ActionForward;
import org.apache.struts.action.ActionMapping;
import org.apache.struts.actions.DispatchAction;
import cn.soldier.bean.Person;
import cn.soldier.service.PersonService;
import cn.soldier.web.form.PersonForm;

public class PersonManageAction extends DispatchAction {
@Resource
PersonService personService;

public ActionForward add(ActionMapping mapping, ActionForm form,HttpServletRequest request, HttpServletResponse response) throws Exception {
//将form转为PersonForm
PersonForm formbean = (PersonForm) form;
//从formbean中获取数据
personService.save(new Person(formbean.getName()));
//
request.setAttribute("message", "添加成功");
//
return mapping.findForward("message");
}
}

3.定义ActionForm
package cn.soldier.web.form;

import org.apache.struts.action.ActionForm;

public class PersonForm extends ActionForm {
/**
* 简单来说，Java的序列化机制是通过在运行时判断类的serialVersionUID来验证版本一致性的。
* 在进行反序列化时，JVM会把传来的字节流中的serialVersionUID与本地相应实体（类）的serialVersionUID进行比较，
* 如果相同就认为是一致的，可以进行反序列化，否则就会出现序列化版本不一致的异常。(InvalidCastException)
*/
private static final long serialVersionUID = 1L;

private Long id;
private String name;

public Long getId() {
return id;
}

public void setId(Long id) {
this.id = id;
}

public String getName() {
return name;
}

public void setName(String name) {
this.name = name;
}

}

4.配置strut-config.xml
<action path="/person/manage" parameter="method" validate="false" scope="request" name="personForm">
<forward name="message" path="/WEB-INF/page/message.jsp"></forward>
</action>

5.配置beans.xml
<bean name="/person/manage" class=" cn.soldier.web.action.PersonManageAction"></bean>

6.这次一个form表单的提交就建立好了。这时可以测试一下。
测试的结果是如果提交的是中文，存进数据库中的是乱码。

7.使用filter，通过spring解决中文乱码问题。配置web.xml
<!--使用spring解决strut1.3的中文乱码问题 -->
<filter>
<filter-name>encoding</filter-name>
<filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
<init-param>
<param-name>encoding</param-name>
<param-value>utf8</param-value>
</init-param>
</filter>
<filter-mapping>
<filter-name>encoding</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>

i使用Spring解决hibernte因Session关闭导致的延迟加载例外问题。
测试步骤忽略
<filter>
<filter-name>OpenSessionViewFilter</filter-name>
<filter-class>org.springframework.orm.hibernate3.support.OpenSessionInViewFilter</filter-class>
</filter>
<filter-mapping>
<filter-name>OpenSessionViewFilter</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
