3.添加配置文件
?? ??? ???? a.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>
?? ??? ??? ??? ??? ?
?? ??? ??? ??? ??? ?<constant name="struts.devMode" value="true"/>

?? ??? ??? ??? ?http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd">
?? ??? ??? ??? ?</beans>
?? ??? ??? ?c.過濾器配置
?? ??? ??? ??? ?修改web.xml文件添加struts核心過濾器
?? ??? ??? ??? ?
?? ??? ??? ??? ?<filter>
?? ??? ??? ??? ??? ?<filter-name>struts</filter-name>
?? ??? ??? ??? ??? ?<filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter</filter-class>
?? ??? ??? ??? ?</filter>
?? ??? ??? ??? ?<filter-mapping>
?? ??? ??? ??? ??? ?<filter-name>struts</filter-name>
?? ??? ??? ??? ??? ?<url-pattern>/*</url-pattern>
?? ??? ??? ??? ?</filter-mapping>
?? ??? ??? ??? ?修改web.xml文件添加Session生命周期開發到web層

?? ??? ??? ??? ??? ?<filter-name>openSessionFilter</filter-name>
?? ??? ??? ??? ??? ?<url-pattern>/*</url-pattern>
?? ??? ??? ??? ?</filter-mapping>
?? ??? ??? ?d.修改web.xml文件添加spring監聽器
?? ??? ??? ??? ?
?? ??? ??? ??? ?<listener>
?? ??? ??? ??? ??? ?<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
?? ??? ??? ??? ?</listener>
?? ??? ??? ??? ?<context-param>
?? ??? ??? ??? ??? ?<param-name>contextConfigLocation</param-name>
?? ??? ??? ??? ??? ?<param-value>classpath:applicationContext.xml</param-value>
?? ??? ??? ??? ?</context-param>
?? ??? ??? ?e.實體類的創建
?? ??? ??? ??? ?@Entity
?? ??? ??? ??? ?@Table(name ="d_book")
?? ??? ??? ??? ?public class Book implements Serializable {
?? ??? ??? ??? ??? ?private static final long serialVersionUID = 1L;
?? ??? ??? ??? ??? ?@Id
?? ??? ??? ??? ??? ?@GeneratedValue(strategy=GenerationType.AUTO)
?? ??? ??? ??? ??? ?private Integer id;
?? ??? ??? ??? ??? ?private String name;
?? ??? ??? ??? ??? ?private Double price;
?? ??? ??? ??? ??? ?private String author;
?? ??? ??? ??? ??? ?//省略getter and setter
?? ??? ??? ??? ?}
?? ??? ??? ?f.在spring核心配置文件applicationContext.xml中添加Hibernate配置信息
?? ??? ??? ??? ?
?? ??? ??? ??? ?<context:property-placeholder location="classpath:jdbc.properties"/>
?? ??? ??? ??? ?
?? ??? ??? ??? ?
?? ??? ??? ??? ?<context:annotation-config/>
?? ??? ??? ??? ?<context:component-scan base-package="cn.jbit"></context:component-scan>
?? ??? ??? ??? ??? ?
?? ??? ??? ??? ?
?? ??? ??? ??? ?<bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource">
?? ??? ??? ??? ??? ?<property name="driverClass" value="${jdbc.driver}"></property>
?? ??? ??? ??? ??? ?<property name="jdbcUrl" value="${jdbc.url}"></property>
?? ??? ??? ??? ??? ?<property name="user" value="${jdbc.user}"></property>
?? ??? ??? ??? ??? ?<property name="password" value="${jdbc.password}"></property>
?? ??? ??? ??? ?</bean>
?? ??? ??? ??? ?
?? ??? ??? ??? ?
?? ??? ??? ??? ?<bean id="sessionFactory" class="org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean">
?? ??? ??? ??? ??? ?
?? ??? ??? ??? ??? ?<property name="dataSource" ref="dataSource"></property>
?? ??? ??? ??? ??? ?
?? ??? ??? ??? ??? ?<property name="hibernateProperties">
?? ??? ??? ??? ??? ??? ?<props>
?? ??? ??? ??? ??? ??? ??? ?<prop key="hibernate.dialect">org.hibernate.dialect.MySQLDialect</prop>
?? ??? ??? ??? ??? ??? ??? ?<prop key="hibernate.show_sql">true</prop>
?? ??? ??? ??? ??? ??? ??? ?<prop key="hibernate.format_sql">true</prop>
?? ??? ??? ??? ??? ??? ??? ?<prop key="hibernate.current_session_context_class">thread</prop>
?? ??? ??? ??? ??? ??? ?</props>
?? ??? ??? ??? ??? ?</property>
?? ??? ??? ??? ??? ?
?? ??? ??? ??? ??? ?<property name="packagesToScan">
?? ??? ??? ??? ??? ??? ?<list>
?? ??? ??? ??? ??? ??? ??? ?<value>cn.jbit.spring9.domain</value>
?? ??? ??? ??? ??? ??? ?</list>
?? ??? ??? ??? ??? ?</property>
?? ??? ??? ??? ?</bean>
?? ??? ??? ??? ?
?? ??? ??? ??? ?
?? ??? ??? ??? ?<bean id="hibernateTemplate" class="org.springframework.orm.hibernate3.HibernateTemplate">
?? ??? ??? ??? ??? ?<property name="sessionFactory" ref="sessionFactory"></property>
?? ??? ??? ??? ?</bean>
?? ??? ??? ??? ?
?? ??? ??? ??? ?
?? ??? ??? ??? ?<bean id="transactionManager" class="org.springframework.orm.hibernate3.HibernateTransactionManager">
?? ??? ??? ??? ??? ?<property name="sessionFactory" ref="sessionFactory"></property>
?? ??? ??? ??? ?</bean>
?? ??? ??? ??? ?
?? ??? ??? ??? ?
?? ??? ??? ??? ?<tx:annotation-driven transaction-manager="transactionManager"/>
4.持久層
?? ??? ?1).接口
?? ??? ??? ?public interface IBookDao {
?? ??? ??? ??? ?public void insert(Book book);
?? ??? ??? ??? ?public Book select(int id);
?? ??? ??? ?}
?? ??? ?2).實現
?? ??? ??? ?@Repository
?? ??? ??? ?public class BookDaoImpl implements IBookDao {
?? ??? ??? ??? ?@Autowired
?? ??? ??? ??? ?private HibernateTemplate hibernateTemplate;
?? ??? ??? ??? ?public void insert(Book book) {
?? ??? ??? ??? ??? ?System.out.println("dao save");
?? ??? ??? ??? ??? ?this.hibernateTemplate.save(book);
?? ??? ??? ??? ?}
?? ??? ??? ?}
?? ??? ??? ?public Book select(int id) {
?? ??? ??? ??? ?return this.hibernateTemplate.load(Book.class, id);
?? ??? ??? ?}
5.業務層
?? ??? ?1).接口
?? ??? ??? ?public interface IBookService {
?? ??? ??? ??? ?public void save(Book book);
?? ??? ??? ??? ?public Book find(int id);
?? ??? ??? ?}
?? ??? ?2).實現
?? ??? ??? ?@Service
?? ??? ??? ?@Transactional
?? ??? ??? ?public class BookServiceImpl implements IBookService {
?? ??? ??? ??? ?@Autowired
?? ??? ??? ??? ?private IBookDao bookDao;
?? ??? ??? ??? ?public void save(Book book) {
?? ??? ??? ??? ??? ?bookDao.insert(book);
?? ??? ??? ??? ?}
?? ??? ??? ??? ?public Book find(int id) {
?? ??? ??? ??? ??? ?return bookDao.select(id);
?? ??? ??? ??? ?}
?? ??? ??? ?}
6.控制器
?? ??? ?1).創建BookAction類繼承ActionSupport
?? ??? ??? ?@Namespace("/")
?? ??? ??? ?@Controller
?? ??? ??? ?public class BookAction extends ActionSupport implements ModelDriven<Book>{
?? ??? ??? ??? ?private Book book = new Book();
?? ??? ??? ??? ?//業務邏輯層
?? ??? ??? ??? ?private IBookService bookService;
?? ??? ??? ??? ?@Action(value="bookAction_add",results={@Result(name="add",location="/index.jsp")})
?? ??? ??? ??? ?public String add(){
?? ??? ??? ??? ??? ?System.out.println("添加信息");
?? ??? ??? ??? ??? ?//bookService.save(book);
?? ??? ??? ??? ??? ?return "add";
?? ??? ??? ??? ?}
?? ??? ??? ??? ?public Book getModel() {
?? ??? ??? ??? ??? ?return book;
?? ??? ??? ??? ?}
?? ??? ??? ??? ?public void setBookService(IBookService bookService) {
?? ??? ??? ??? ??? ?this.bookService = bookService;
?? ??? ??? ??? ?}
?? ??? ??? ??? ?@Action(value="bookAction_load",results={@Result(name="load",location="/index.jsp")})
?? ??? ??? ??? ?public String load(){
?? ??? ??? ??? ??? ?book = bookService.find(1);
?? ??? ??? ??? ??? ?System.out.println(book);
?? ??? ??? ??? ??? ?return "load";
?? ??? ??? ??? ?}
?? ??? ??? ?}
7.表示層
????以表單方式提交數據，此處省略!
