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

Spring MVC屬於SpringFrameWork的後續產品，已經融合在Spring Web Flow裏面。Spring 框架提供了構建 Web 應用程序的全功能 MVC 模塊。使用 Spring 可插入的 MVC 架構，從而在使用Spring進行WEB開發時，可以選擇使用Spring的SpringMVC框架或集成其他MVC開發框架,如hibernate，MyBatis等。

註解：
掃描指定的包中的類上的註解，常用的註解有：
@Controller 聲明Action組件 @RequestMapping (“/user”) @RequestMapping (“/login”)
@Service 聲明Service組件 @Service(“myMovieLister”)
@Repository 聲明Dao組件
@Component 泛指組件, 當不好歸類時.
@RequestMapping(“/menu”) 請求映射
@Resource 用於注入，( j2ee提供的 ) 默認按名稱裝配，@Resource(name=”beanName”)
@Autowired 用於注入，(srping提供的) 默認按類型裝配
@Transactional( rollbackFor={Exception.class}) 事務管理
@ResponseBody 返回數據以json數據形式返回
@Scope(“prototype”) 設定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的分發配置文件
        </init-param>
     </servlet >

     <servlet-mapping >
         <servlet-name> springmvc</servlet-name >
         <url-pattern> /</ url-pattern>//攔截/user/login
     </servlet-mapping >
 <context-param >
                    <param-name> contextConfigLocation</param-name >
                   <param-value> classpath:application-context.xml</param-value >//數據庫初始化，事務初始化，model層掃描
     </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對靜態資源的訪問 -->
        <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.數據庫鏈接，model層掃描，事務配置
