5.使用spring注解注入service,DAO
?action：

@ParentPackage(value = "struts-default") @Namespace("/") @Controller @Scope("prototype") public class BookAction extends ActionSupport implements ModelDriven<Book>{ //模型驅動 public Book book = new Book(); public void setBook(Book book) { this.book = book; } @Override public Book getModel() { return book; } @Autowired @Qualifier("bookService") private BookService bookService; @Override @Action(value="addBook",results={@Result(name="success",location="/success.jsp")}) public String execute() throws Exception { bookService.save(book); return SUCCESS; }

?service:

@Service("bookService") @Transactional public class BookService { @Autowired @Qualifier("bookDAO") private BookDAO bookDAO; public void save(Book book) { bookDAO.save(book); }

}
6.DAO完成數據操作，首先要有hibernateTemplate，通過spring注解注入?

@Repository("bookDAO") public class BookDAO { @Autowired @Qualifier("hibernateTemplate")? private HibernateTemplate hibernateTemplate; public void save(Book book) { this.hibernateTemplate.save(book); }

7.實體類，不再需要hbm.xml文件?
?@Entity

@Table(name = "book") public class Book { @Id private int id; @Column(name="name") private String name; @Column(name="author") private String author;
8.applicationContext.xml文件
?<!-- 自動掃描 --> <context:component-scan base-package="cn.yuzhi"></context:component-scan> <!-- 注解注入 --> <context:annotation-config></context:annotation-config> <!-- 引入外部屬性文件 --> <context:property-placeholder location="classpath:jdbc.properties"/> <property name="password" value="${jdbc.password}"></property> </bean> <!-- 定義Bean ： SessionFactory ?--> <bean id="sessionFactory" class="org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean"> <!-- 將連接池注入到SessionFactory --> <property name="dataSource" ref="dataSource"></property> <!-- 配置hibernate常用屬性 --> <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.hbm2ddl.auto">update</prop> </props> </property> <!-- 引用注解類 ,不再引用hbm文件--> <property name="packagesToScan"> <list> <value>cn.yuzhi.domain</value> </list> </property> </bean> <bean id="hibernateTemplate" class="org.springframework.orm.hibernate3.HibernateTemplate"> <property name="sessionFactory" ref="sessionFactory"></property> </bean> <!-- spring 采用聲明式事務管理 ?--> <bean id="transactionManager" class="org.springframework.orm.hibernate3.HibernateTransactionManager"> <property name="sessionFactory" ref="sessionFactory"></property> </bean> <tx:annotation-driven transaction-manager="transactionManager"/>
