<!--
  - DispatcherServlet application context for the Countries web tier.
  -->
<beans>

 <!-- ========================= MAPPING DEFINITIONS ========================= -->

 <!--
   - 使用ResourceBundleViewResolver代替默认内部的资源视图解析器(InternalResourceViewResolver)声明绑定的视图映射.
   - 从本地类路径文件"views_appname"获取视图映射,例如.
   - "/WEB-INF/classes/views-countries.properties" 或 "/WEB-INF/classes/views-countries_fr.properties".
   -
   - 由控制器(controllers)返回的视图的名字将被在各自的属性文件里解析,允许任意的在名字-资源间的映射
   - 我们使用"defaultParentView" 属性. 所有视图的定义将默认继承"modelView"视图定义的属性.
   -->
 <bean id="viewResolver" class="org.springframework.web.servlet.view.ResourceBundleViewResolver">
  <property name="basename" value="views-countries"/>
  <property name="defaultParentView" value="modelView"/>
 </bean>

 <!--
  - 我们再次指定保存在cookies里的现场和主题(theme).
   - 他们被保存在一个会话里(Session). 默认的解析器不允许在闲置时更改他们.
  -->
 <bean id="localeResolver" class="org.springframework.web.servlet.i18n.CookieLocaleResolver"/>

 <bean id="themeResolver" class="org.springframework.web.servlet.theme.CookieThemeResolver">
  <property name="defaultThemeName" value="spring"/>
 </bean>

 <!--
  - 使用SimpleUrlHandlerMapping代替 BeanNameUrlHandlerMapping声明URL handler 映射.
  -->
 <bean id="urlMapping" class="org.springframework.web.servlet.handler.SimpleUrlHandlerMapping">
  <property name="interceptors">
   <list>
    <ref bean="localeChangeInterceptor"/>
    <ref bean="themeChangeInterceptor"/>
   </list>
  </property>
  <property name="mappings">
   <props>
    <prop key="/home.htm">countriesController</prop>
    <prop key="/config.htm">countriesController</prop>
    <prop key="/copy.htm">countriesController</prop>
    <prop key="/main/home.htm">countriesController</prop>
    <prop key="/main/detail.htm">countriesController</prop>
    <prop key="/main/countries.xls">countriesController</prop>
    <prop key="/main/countries.pdf">countriesController</prop>
    <prop key="/notfound.htm">errorsController</prop>
   </props>
  </property>
 </bean>

 <!-- ========================= CONTROLLER DEFINITIONS ========================= -->

 <!--
  - 拦截器将会预先操控(pre-handle)该servlet中任何请求,而不管哪个controller已经映射于该请求
  - 我们使用两个内建的拦截器来检查使用者的现场(locale)或主题(theme)更改请求.
  - 第三个拦截器在该演示中指定. 它使视图很容易的了解到配置已经被检测过了
  - 同时会了解是否一份数据库的数据拷贝可以提供给使用者.
 -->
 <bean id="localeChangeInterceptor" class="org.springframework.web.servlet.i18n.LocaleChangeInterceptor"/>

 <bean id="themeChangeInterceptor" class="org.springframework.web.servlet.theme.ThemeChangeInterceptor"/>

 <!-- 一般用法,使用multi-action controller for errors -->
 <bean id="errorsController" class="org.springframework.samples.countries.web.ErrorsController">
  <property name="methodNameResolver">
   <bean class="org.springframework.web.servlet.mvc.multiaction.PropertiesMethodNameResolver">
    <property name="mappings">
     <props>
      <prop key="/notfound.htm">handleHttp404</prop>
     </props>
    </property>
   </bean>
  </property>
 </bean>

 <!-- Application specific multi-action controller -->
 <bean id="countriesController" class="org.springframework.samples.countries.web.CountriesController">
  <property name="methodNameResolver">
   <bean class="org.springframework.web.servlet.mvc.multiaction.PropertiesMethodNameResolver">
    <property name="mappings">
