hibernate+spring

一，新建一个web工程，添加hibernate的支持（要选择copy方式来引入jar包，不要用映射方式的，而且要注意不要创建hibernate的sessionFactory的类）二，随即添加spring的支持（要选择copy方式来引入jar包，不要用映射方式的，在选择的时候选择五个jar包，前面三个，和web和mis）三，偷梁换柱，把asm2.2.3的这个包删掉，build path -->config build path -- > remove asm2.2.3 ,删掉这里面的之后，还要删除lib包下面的jar包四，把log4j属性文件放置src目录下面五，先对数据库的表反转生成pojo类和DAO的方法，然后把dao层的方法移到dao层，然后建立service的包和action的包六，配置hibernate.cfg.xml中的一些配置项（要使用连接池要手工的导入c3p0的包）<property name="show_sql">true</property><propertyname="connection.driver_class">org.hibernate.connection.C3P0ConnectionProvider</property><propertyname="cache.provider_class">org.hibernate.cache.OSCacheProvider</property> <property name="hbm2ddl.auto">update</property>七，写一个测试的方法得到一张表的所有内容，到页面显示action中的内容：action是要交个springMVC-servlet.xml里面来注册的@Controller@RequestMapping("/article.do")public class ArticleAction {@Resource private PersonService personService ;@RequestMapping(params="method=getAllArticles")public void getAllArticles(HttpServletRequest request,HttpServletResponse response) throws ServletException, IOException{List<Articles> articlesList = personService.getArticlesList();request.setAttribute("list", articlesList);request.getRequestDispatcher("/myjsp.jsp").forward(request, response);}}七，把applicationContext.xml中的头子换掉，然后在里面配置事务管理<bean id="sessionFactory"class="org.springframework.orm.hibernate3.LocalSessionFactoryBean"><property name="configLocation"value="classpath:hibernate.cfg.xml"></property></bean><!-- 事务管理器 --><bean id="transactionManager" class="org.springframework.orm.hibernate3.HibernateTransactionManager"> <property name="sessionFactory" ref="sessionFactory"/></bean><!-- 注解方式的事务 --><tx:annotation-driven transaction-manager="transactionManager"/><!-- xml的事务管理 --><!-- <aop:config><aop:pointcut id="mypt" expression="execution(* hwt.service.PersonService.*(..))"/><aop:advisor advice-ref="mytx" pointcut-ref="mypt"/></aop:config><tx:advice id="mytx" transaction-manager="transactionManager"><tx:attributes><tx:method name="get*" propagation="NOT_SUPPORTED"/><tx:method name="*"/></tx:attributes></tx:advice> --><!-- 用扫描的方式来注册bean --><context:component-scan base-package="hwt.service"/><!-- 注册dao --><bean id="ArticlesDAO" class="hwt.DAO.ArticlesDAO"><property name="sessionFactory"><ref bean="sessionFactory" /></property></bean>八，配置完了之后不要急着去页面测试，先到控制台输出一下结果public static void main(String[] args) {ApplicationContext act = new ClassPathXmlApplicationContext("applicationContext.xml");PersonService personService= (PersonService) act.getBean("personService");List<Articles> articleList = personService.getArticlesList();for (Articles articles : articleList) {System.out.println(articles.getAtitle());}}九，配置web.xml<!--context配置--><context-param><param-name>contextConfigLocation</param-name><param-value>classpath:app*.xml</param-value></context-param><!-- 过滤器 --><filter><filter-name>chineseFilter</filter-name><filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter -class><init-param><param-name>encoding</param-name><param-value>utf-8</param-value></init-param></filter><filter-mapping><filter-name>chineseFilter</filter-name><url-pattern>/*</url-pattern></filter-mapping><!--监听器--><listener><listener-class>org.springframework.web.context.ContextLoaderListener</liste ner-class></listener><!--spring的DispatcherServlet--><servlet><servlet-name>SpringMVC</servlet-name><servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-cl ass><load-on-startup>0</load-on-startup></servlet><servlet-mapping><servlet-name>SpringMVC</servlet-name><url-pattern>*.do</url-pattern></servlet-mapping>要在WEB-INF下面配置SpringMVC-servlet.xml<?xml version="1.0" encoding="UTF-8"?><beans xmlns="/schema/beans"xmlns:xsi="/2001/XMLSchema-instance"xmlns:p="/schema/p"xmlns:context="/schema/context"xsi:schemaLocation="/schema/beans/schema/beans/spring-beans-2.5.xsd/schema/context/schema/context/spring-context-2.5.xsd"><!-- 扫描 --><context:component-scanbase-package="hwt.action"></context:component-scan></beans>ps:如果在service层需要用到SessionFactory的话可以依赖注入到serviceBean中如：@resource private SessionFactory factory;//要用factory.getCurrentSession()；来得到session，这样得到的session是有spring来管理的public void test(Articles articles){//如果在service层需要用到session的话Session session = factory.getCurrentSession();session.persist(articles);}。
