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"
xmlns:aop="http://www.springframework.org/schema/aop" xmlns:tx="http://www.springframework.org/schema/tx"
xsi:schemaLocation="http://www.springframework.org/schema/beans

<!--导入外部properties -->
<context:property-placeholder location="classpath:jdbc.properties" />
<!--配置数据源 -->

<!--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);
}
}
}

/*******************************************以上步骤集成了Spring+Hibernate****************************************************/

2.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">
<!--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 -->

</welcome-file-list>

</web-app>

3.配置classpath下的 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>

<!-- 指定Web应用的默认编码集，相当于调用 HttpServletRequest的setCharacterEncoding方法 -->
<constant name="struts.i18n.encoding" value="http://www.mamicode.com/UTF-8" />
<!-- 该 属性指定需要Struts2处理的请求后缀，该属性的默认值是action，即 所有匹配*.action的请求都由Struts 2处理。如
果用户需要指定多个请求后缀，则多个后缀之间以英文逗号（，）隔开 -->
<constant name="struts.action.extension" value="http://www.mamicode.com/action" />
<!-- 设 置浏览器是否缓存静态内容，默认值为true（生产环境下使用），开发阶段最好 关闭 -->
<constant name="struts.serve.static.browserCache " value="http://www.mamicode.com/false" />
<!-- 当 struts的配置文件修改后，系统是否自动重新加载该文件，默认值为false（生 产环境下使用），开发阶段最好打开 -->

<!-- 默 认的视图主题 -->
<constant name="struts.ui.theme" value="http://www.mamicode.com/simple" />
<!-- 该 属性指定Struts 2中的action由Spring容器创 建 -->
<constant name="struts.objectFactory" value="http://www.mamicode.com/spring" />
<package name="person" namespace="/person" extends="struts-default">
<global-results>
<result name="message">/WEB-INF/page/message.jsp</result>

<action name="action_*" class="personList" method="{1}">
<result name="list">/WEB-INF/page/list.jsp</result>
<result name="add">/WEB-INF/page/add.jsp</result>
</action>
</package>
</struts>

4.配置beans.xml
<bean id="personList" class="cn.soldier.web.PersonAction"></bean>

5.添加 list.jap
<%@ page language="java" import="java.util.*" pageEncoding="utf-8"%>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<%@ taglib uri="/struts-tags" prefix="s"%>

</s:iterator>
<body>
</body>
</html>
6.创建 PersonAction.java

package cn.soldier.web;

import java.util.List;
import javax.annotation.Resource;
import cn.soldier.bean.Person;
import cn.soldier.service.PersonService;

public class PersonAction {
@Resource
PersonService personService;
private String message;
private List<Person> persons;
private Person person;// 负责接收form表单的参数

public String list() {
this.persons = personService.getPersons();
return "list";
}

public String add() {
personService.save(this.person);
this.message = "添加成功";
return "message";
}

public String addUI() {

return "add";
}

public String getMessage() {
return message;
}

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

public List<Person> getPersons() {
return persons;
}

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

public Person getPerson() {
return person;
}

public void setPerson(Person person) {
this.person = person;
}
}
