2022-06-15 00:46:43

所使用的Jar包：

Hibernate：

Spring（使用MyEclipse自动导入框架功能）

Struts2:

注解包和MySql驱动包：

1、配置Hibernate和Spring：

<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"

	xmlns:context="http://www.springframework.org/schema/context"

	xmlns:tx="http://www.springframework.org/schema/tx"

	xmlns:aop="http://www.springframework.org/schema/aop"

	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/tx

	http://www.springframework.org/schema/tx/spring-tx-2.5.xsd

	http://www.springframework.org/schema/aop

	http://www.springframework.org/schema/aop/spring-aop-2.5.xsd">

	<context:annotation-config />

	<bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource" destroy-method="close">

		<property name="driverClassName" value="com.mysql.jdbc.Driver" />

		<property name="url"

			value="jdbc:mysql://localhost:3306/ssh?useUnicode=true&characterEncoding=UTF-8" />

		<property name="username" value="root" />

		<property name="password" value="" />

		<!--初始化时获取的连接数，取值应在minPoolSize与maxPoolSize之间。Default: 3 -->

		<property name="initialSize" value="1" />

		<!--连接池中保留的最大连接数。Default: 15 -->

		<property name="maxActive" value="500" />

		<!--最大空闲值,当经过一段峰值以后，连接会被释放掉一部分，直到释放到maxidle -->

		<property name="maxIdle" value="2" />

		<!--最小空闲值 当空闲的连接数小于阀值时，连接池会主去的去申请一些连接 -->

		<property name="minIdle" value="1" />

	</bean>

	<bean id="sessionFactory" class="org.springframework.orm.hibernate4.LocalSessionFactoryBean" >

		<property name="dataSource" ref="dataSource" />

		<property name="mappingResources">

			<list>

				<value>cn/raffaello/hbm/Person.hbm.xml</value>

			</list>

		</property>

		<property name="hibernateProperties">

			<value>

				hibernate.dialect=org.hibernate.dialect.MySQL5Dialect

				hibernate.hbm2ddl.auto=update

				hibernate.show_sql=true

				hibernate.format_sql=false

			</value>

		</property>

	</bean>

	<bean id="txManager" class="org.springframework.orm.hibernate4.HibernateTransactionManager">

		<property name="sessionFactory" ref="sessionFactory" />

	</bean>

	<tx:annotation-driven transaction-manager="txManager"/>

	<bean id="personIDao" class="cn.raffaello.dao.impl.PersonDaoImpl" />

	<bean id="personIService" class="cn.raffaello.service.impl.PersonServiceImpl">

		<property name="personIDao" ref="personIDao" />

	</bean>

</beans>

2、新建实体和映射文件：

public class Person {

	public Person(){}

	public Person(String name) {

		super();

		this.name = name;

	}

	private Integer id;

	private String name;

	public Integer getId() {

		return id;

	}

	public void setId(Integer id) {

		this.id = id;

	}

	public String getName() {

		return name;

	}

	public void setName(String name) {

		this.name = name;

	}

}

<hibernate-mapping package="cn.raffaello.model">

	<class name="Person" table="PERSON">

		<id name="id" column="ID">

			<generator class="native" />

		</id>

		<property name="name" column="NAME" />

	</class>

</hibernate-mapping>

3、新建DaoBean，并在Bean中实现部分方法，使用@Resource给SessionFactory注入:

public interface PersonIDao {

	void add(Person person);

	void update(Person person);

	Person getById(Integer id);

	List<Person> getPersons();

}

public class PersonDaoImpl implements PersonIDao {

	@Resource(name="sessionFactory")

	private SessionFactory sessionFactory;

	@Override

	public void add(Person person) {

		sessionFactory.getCurrentSession().persist(person);

	}

	@Override

	public void update(Person person) {

		sessionFactory.getCurrentSession().merge(person);

	}

	@Override

	public Person getById(Integer id) {

		return (Person)sessionFactory.getCurrentSession().get(Person.class, id);

	}

	@SuppressWarnings("unchecked")

	@Override

	public List<Person> getPersons() {

		return sessionFactory.getCurrentSession().createQuery("from Person").list();

	}

}

5、新建ServiceBean，并实现部分方法；在ServiceBean的头部添加@Transactional 注解，使用该ServiceBean纳入Spring事务管理；

public interface PersonIService {

	void add(Person person);

	void update(Person person);

	Person getById(Integer id);

	List<Person> getPersons();

}

@Transactional

public class PersonServiceImpl implements PersonIService {

	private PersonIDao personIDao;

	@Override

	public void add(Person person) {

		personIDao.add(person);

	}

	@Override

	public void update(Person person) {

		personIDao.update(person);

	}

	@Transactional(readOnly=true)

	@Override

	public Person getById(Integer id) {

		return personIDao.getById(id);

	}

	@Transactional(readOnly=true)

	@Override

	public List<Person> getPersons() {

		return personIDao.getPersons();

	}

	public PersonIDao getPersonIDao() {

		return personIDao;

	}

	public void setPersonIDao(PersonIDao personIDao) {

		this.personIDao = personIDao;

	}

}

6、测试Spring和Hibernate的代码：

public class test {

	private static PersonIService personIService;

	@BeforeClass

	public static void init(){

		ApplicationContext cxt=new ClassPathXmlApplicationContext("beans.xml");

		personIService=(PersonIService)cxt.getBean("personIService");

	}

	@Test

	public void test() {

		personIService.add(new Person("克露丝"));

		personIService.add(new Person("Json"));

		personIService.add(new Person("布尔曼"));

		personIService.add(new Person("HHH"));

		personIService.add(new Person("汤姆"));

	}

	@Test

	public void testUpdate(){

		Person person=personIService.getById(1);

		person.setName("汉克丝 hankesi");

		personIService.update(person);

	}

	@Test

	public void testList(){

		List<Person> list=personIService.getPersons();

		for(Person per : list){

			System.out.println(per.getName());

		}

	}

}

7、整合Struts2+Spring+Hibernate，将下面代码添加到Web.xml中：

<listener>

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

  </listener>

  <context-param>

    <param-name>contextConfigLocation</param-name>

    <param-value>classpath:beans.xml</param-value>

  </context-param>

  <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>

8、在Struts.xml中进行如下配置：

	<constant name="struts.118n.encoding" value="UTF-8" />

	<!-- Action 后缀 -->

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

    <!-- 设置浏览器是否缓存静态内容，默认值为true,开发环境下建议设置为false -->

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

    <!-- 当Struts　修改文件以后，是否重新加载该文件，默认为false,推荐开发环境下设置为true -->

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

    <!-- 开发模式下可以打印更详细的错误信息 -->

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

    <!-- 默认视图主题  -->

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

    <!-- 与Spring集成是，指定有Spring创建Action对象 -->

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

    <package name="raffaello" namespace="/raffaello" extends="struts-default">

    	<action name="main_*" class="cn.raffaello.action.MainAction" method="{1}">

    		<result name="message">/WEB-INF/pages/message.jsp</result>

    		<result name="list">/WEB-INF/pages/list.jsp</result>

    	</action>

    </package>

9、新建Action：MainAction:

public class MainAction {

	private String message;

	private Person person;

	private PersonIService personIService;

	public String hello(){

		setMessage("struts2 测试消息！");

		return "message";

	}

	public String save(){

		if(person!=null && !person.getName().equals("")){

			personIService.add(person);

			setMessage("添加成功");

		}else{

			setMessage("对象为空");

		}

		return "message";

	}

	public String list(){

		List<Person> list=personIService.getPersons();

		HttpServletRequest request=ServletActionContext.getRequest();

		request.setAttribute("PersonList", list);

		return "list";

	}

	public String getMessage() {

		return message;

	}

	public void setMessage(String message) {

		this.message = message;

	}

	public Person getPerson() {

		return person;

	}

	public void setPerson(Person person) {

		this.person = person;

	}

	public PersonIService getPersonIService() {

		return personIService;

	}

	public void setPersonIService(PersonIService personIService) {

		this.personIService = personIService;

	}

}

10、添加测试代码和获取的测试代码：

	<form action="/SSH2/raffaello/main_save.do" method="post">

    		添加人员     <a target="_blank" href="/SSH2/raffaello/main_list.do">人员列表</a>

    		<hr />

    		姓名：<input type="text" name="person.name" />

    		<input type="submit" value="提交">

    	</form>

<span style="white-space:pre">	</span><c:forEach items="${PersonList}" var="per">

    		${per.name}

    	</c:forEach>
