springMVC框架整合--（Spring+SpringMVC+hibernate）

Spring MVC属于SpringFrameWork的后续产品，已经融合在Spring Web Flow里面。Spring 框架提供了构建 Web 应用程序的全功能 MVC 模块。使用 Spring 可插入的 MVC 架构，从而在使用Spring进行WEB开发时，可以选择使用Spring的SpringMVC框架或集成其他MVC开发框架,如hibernate，MyBatis等。

注解：
扫描指定的包中的类上的注解，常用的注解有：
@Controller 声明Action组件 @RequestMapping (“/user”) @RequestMapping (“/login”)
@Service 声明Service组件 @Service(“myMovieLister”)
@Repository 声明Dao组件
@Component 泛指组件, 当不好归类时.
@RequestMapping(“/menu”) 请求映射
@Resource 用于注入，( j2ee提供的 ) 默认按名称装配，@Resource(name=”beanName”)
@Autowired 用于注入，(srping提供的) 默认按类型装配
@Transactional( rollbackFor={Exception.class}) 事务管理
@ResponseBody 返回数据以json数据形式返回
@Scope(“prototype”) 设定bean的作用域

1.配置web.xml ， 使用Spring MVC,配置DispatcherServlet

<servlet>         <servlet-name> springmvc</servlet-name >         <servlet-class> org.springframework.web.servlet.DispatcherServlet</servlet-class >         <init-param>              <param-name> contextConfigLocation</param-name >             <param-value> classpath:dispatcher-servlet.xml</param-value > //SpringMvc的分发配置文件        </init-param>     </servlet >     <servlet-mapping >         <servlet-name> springmvc</servlet-name >         <url-pattern> /</ url-pattern>//拦截/user/login     </servlet-mapping > <context-param >                    <param-name> contextConfigLocation</param-name >                   <param-value> classpath:application-context.xml</param-value >//数据库初始化，事务初始化，model层扫描     </context-param ><listener>      <listener-class> org.springframework.web.context.ContextLoaderListener</listener-class >    </listener >

2.dispatcher-servlet.xml或者springMVC.xml的配置

<!-- Enables the Spring MVC @Controller programming model -->     <mvc:annotation-driven >           <mvc:argument-resolvers>                    <bean class="org.springframework.mobile.device.DeviceWebArgumentResolver" />               <bean                    class= "org.springframework.mobile.device.site.SitePreferenceWebArgumentResolver" />           </mvc:argument-resolvers>     </mvc:annotation-driven ><!-- Handles HTTP GET requests for /resources/** by efficiently serving          up static resources in the ${webappRoot}/resources directory -->     <mvc:resources mapping="/resources/**" location="/resources/" />     <!-- spring mvc对静态资源的访问 -->        <mvc:resources location= "/image/" mapping="/image/**" />               <mvc:resources location= "/js/" mapping ="/js/**"/>                <mvc:resources location= "/css/" mapping="/css/**" />                         <mvc:resources location="/static/" mapping="/static/**"/>     <!-- Resolves views selected for rendering by @Controllers to .jsp resources          in the /WEB-INF/views directory -->           <bean class="org.springframework.mobile.device.view.LiteDeviceDelegatingViewResolver" >           <constructor-arg>               <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver" >                    <property name= "prefix" value="/WEB-INF/views/" />                    <property name= "suffix" value =".jsp" />               </bean>           </constructor-arg>           <property name= "enableFallback" value ="true" />           <property name= "mobilePrefix" value ="mobile/" />           <property name= "tabletPrefix" value ="tablet/" />     </bean ><!-- json -->   <bean class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter" >           <property name="messageConverters">                <list >                   <ref bean="mappingJacksonHttpMessageConverter" />               </list>            </property >         </bean > 

3.数据库链接，model层扫描，事务配置

4.jdbc.properties配置

jdbc.url=jdbc\:mysql \://localhost\:3306/test?useUnicode\=true&characterEncoding\=UTF-8jdbc.user=rootjdbc.pass=jdbc.driver=com.mysql.jdbc.Driver
