1.创建web项目

2.引入类库

slf4j-log4j12.jar

com.springsource.javax.annotation-1.0.0.jar

com.springsource.javax.xml.bind-2.1.7.jar

3.配置web.xml文件

    <!-- 通过上下文参数指定分解的上下文配置文件 --><context-param><param-name>contextConfigLocation</param-name><param-value>classpath:beans.xml</param-value></context-param><listener><listener-class>org.springframework.web.context.ContextLoaderListener</listener-class></listener>    <!-- 配置spring dispatcherServlet --><servlet><servlet-name>action</servlet-name><servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class><!-- 通过初始化参数指定xml配置位置 --><init-param><param-name>contextConfigLocation</param-name><param-value>classpath:springmvc.xml</param-value></init-param></servlet>

4 编写beans.xml

        <!-- 注解驱动 -->        <mvc:annotation-driven/>        <!-- 组件扫描 -->        <context:component-scan base-package="mym.springmvc"/>         <!-- 数据源 -->        <bean id="dataSource"  class="com.mchange.v2.c3p0.ComboPooledDataSource">           <property name="driverClass" value="com.mysql.jdbc.Driver" />   <property name="jdbcUrl" value="jdbc:mysql://localhost:3306/springmvc" />   <property name="user" value="root" />   <property name="password" value="root" />   <property name="maxPoolSize" value="10" />   <property name="minPoolSize" value="5" />     <property name="initialPoolSize" value="5" />        </bean>        <!-- 本地会话工厂bean -->        <bean id="Sessionfactory"  class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">            <property name="dataSource" ref="dataSource"/>            <property name="hibernateProperties">                  <props>                     <prop key="hibernate.Dialect">org.hibernate.dialect.MySQL5Dialect</prop>     <prop key="hibernate.show_sql">true</prop>     <prop key="hibernate.hbm2ddl.auto">update</prop>                  </props>            </property>            <property name="mappingDirectoryLocations">                 <value>classpath:mym/springmvc/domain</value>            </property>        </bean>        <!-- 事物管理器 -->        <bean id="htm"  class="org.springframework.orm.hibernate3.HibernateTransactionManager">            <property name="sessionFactory" ref="Sessionfactory"/>        </bean>        <!-- 事物通知 -->        <tx:advice id="txadvice" transaction-manager="htm">           <tx:attributes><tx:method name="save*" propagation="REQUIRED"/><tx:method name="delete*" propagation="REQUIRED"/><tx:method name="update*" propagation="REQUIRED"/><tx:method name="find*" read-only="true"/><tx:method name="*" read-only="true"/></tx:attributes>        </tx:advice>               <aop:config><aop:advisor pointcut="execution(* mym.springmvc.service.*.*(..))" advice-ref="txadvice"/>   </aop:config></span>

*这里注解驱动和组件扫描配置在了这里

5.编写spring-mvc.xml

<span style="font-size:12px;"> <!-- 内部资源视图解析器 -->    <bean id="internalResourceViewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver">          <property name="prefix" value="/WEB-INF/jsps/"/>          <property name="suffix" value=".jsp"/>    </bean></span>

6.定义Person实体类

7.定义Person实体类的映射文件Person.hbm.xml

8.创建Persons表

9.定义Dao的接口和实现类，并注入sessionFactory

<span style="font-size:12px;">@Repository(value="personDao")public class PersonDaoImpl implements PersonDao{     @Resource(name="sf")     private SessionFactory sf;     public void deletePerson(Person p) {        sf.getCurrentSession().delete(p);     }     public List<Person> findAllPerson() {        return sf.getCurrentSession().createQuery("from Person").list();     }     public Person findPersonById(String id) {        return (Person)sf.getCurrentSession().get(Person.class, id);     }    public void savePerson(Person p) {        sf.getCurrentSession().save(p);     }    public void updatePerson(Person p) {       sf.getCurrentSession().update(p);     }}</span><strong style="font-size:18px;"></strong>

*@Repository(value="personDao") 不写value属性默认是类名首字母小写 value也可以不写直接 @Repository("personDao")

*@Resource(name="sf") private SessionFactory sf;
name属性不写先去容器找 id为sf的bean 如果没找到找类型为SessionFactory的bean

name属性如果写了只会以id为sf的找

10.定义Service的接口和实现类，并注入dao

11.定义Controller，并注入service

@Controller@RequestMapping(value="/person")public class PersonController {@Resourceprivate PersonService personService;@RequestMapping(value="/savePersonUI")public String savePersonUI(){return "savePersonForm";}@RequestMapping(value="/save")public String savePerson(Person p){personService.save(p);System.out.println("savePerson()...");return "redirect:/person/list";}@RequestMapping(value="/list")public String personList(HttpServletRequest request){List<Person> list = personService.findAll();request.setAttribute("list", list);return "personList";}@RequestMapping(value="/delete")public String deletePerson(Person p){Person p1 = new Person();p1.setId("001");personService.delete(p1);return "redirect:/person/list";}@RequestMapping(value="/deleteAll")public String deletePerson(String ids){ids = ids.substring(0, ids.length()-1);String[] idss = ids.split(",");Person p = new Person();for(int i=0;i<idss.length;i++){p.setId(idss[i]);personService.delete(p);}return "redirect:/person/list";}@RequestMapping(value="/updateForUI")public String updateForUI(String id,HttpServletRequest request){Person p = personService.findPersonById(id);request.setAttribute("p", p);return "update";}@RequestMapping(value="/updatePerson")public String updatePerson(Person p){personService.update(p);return "redirect:/person/list";}

*return "redirect:/person/list"; 重定向不写的话就是转发这里必须要用重定向不然如果是删除的话会再删除一次

12.创建jsp页面

*springmvc 会有中文乱码问题要加一个过滤器解决乱码
