Spring MVC 中怎么设置使用多视图解析器-JSP与FreeMarker

首先是在Web.xml 中配置请求分法器 代码如下：
<?xml version="1.0" encoding="UTF-8"?>
<web-app version="2.4" xmlns="http://java.sun.com/xml/ns/j2ee"
??? xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
??? xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee
??? http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd">
??? <listener>
??? ??? <listener-class>
??? ??? ??? org.springframework.web.context.ContextLoaderListener
??? ??? </listener-class>
??? </listener>
??? <!-- ======================================================== -->
??? <!--????????????????? Spring MVC Config Servlet?????????????? -->
??? <!-- ======================================================== -->
??? <!-- JSP DispatcherServlet -->
??? <servlet>
??? ??? <servlet-name>jspdpt</servlet-name>
??? ??? <servlet-class>
??? ??? ??? org.springframework.web.servlet.DispatcherServlet
??? ??? </servlet-class>
??? ??? <load-on-startup>1</load-on-startup>
??? </servlet>
??? <!-- FreeMarker DispatcherServlet -->
??? <servlet>
??? ??? <servlet-name>ftldpt</servlet-name>
??? ??? <servlet-class>
??? ??? ??? org.springframework.web.servlet.DispatcherServlet
??? ??? </servlet-class>
??? ??? <load-on-startup>2</load-on-startup>
??? </servlet>

??? <!-- ======================================================== -->
??? <!--????????????????? Spring MVC Config Mapping?????????????? -->
??? <!-- ======================================================== -->
??? <servlet-mapping>
??? ??? <servlet-name>jspdpt</servlet-name>
??? ??? <url-pattern>*.view</url-pattern>
??? </servlet-mapping>

??? <servlet-mapping>
??? ??? <servlet-name>ftldpt</servlet-name>
??? ??? <url-pattern>*.ftl</url-pattern>
??? </servlet-mapping>

??? <welcome-file-list>
??? ??? <welcome-file>index.html</welcome-file>
??? </welcome-file-list>

??? <jsp-config>
??? ??? <taglib>
??? ??? ??? <taglib-uri>/spring</taglib-uri>
??? ??? ??? <taglib-location>/WEB-INF/spring.tld</taglib-location>
??? ??? </taglib>
??? </jsp-config>
</web-app>
然后为不同的servlet 映射编写不同的Spring 的IOC 容器：
<?xml version="1.0" encoding="GB2312"?>
<beans xmlns="http://www.springframework.org/schema/beans"
??? xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
??? xmlns:util="http://www.springframework.org/schema/util"
??? xsi:schemaLocation="
??? http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.0.xsd
??? http://www.springframework.org/schema/util http://www.springframework.org/schema/util/spring-util-2.0.xsd">

??? <!-- ===================================================== -->
??? <!--?????????? ViewResolver For FreeMarker???????????????? -->
??? <!-- ===================================================== -->
??? <bean id="viewResolver"
??? ??? class="org.springframework.web.servlet.view.freemarker.FreeMarkerViewResolver">
??? ??? <property name="cache">
??? ??? ??? <value>true</value>
??? ??? </property>
??? ??? <property name="suffix">
??? ??? ??? <value>.ftl</value>
??? ??? </property>
??? ??? <property name="exposeRequestAttributes">
??? ??? ??? <value>true</value>
??? ??? </property>
??? ??? <property name="exposeSessionAttributes">
??? ??? ??? <value>true</value>
??? ??? </property>
??? ??? <property name="exposeSpringMacroHelpers">
??? ??? ??? <value>true</value>
??? ??? </property>
??? ??? <property name="contentType">
??? ??? ??? <value>text/html; charset=GB2312</value>
??? ??? </property>
??? </bean>
??? <!-- ===================================================== -->
??? <!--??? ViewResolver For FreeMarkerConfigurer????????????? -->
??? <!-- ===================================================== -->
??? <bean id="freemarkerConfig"
??? ??? class="org.springframework.web.servlet.view.freemarker.FreeMarkerConfigurer">
??? ??? <property name="templateLoaderPath">
??? ??? ??? <value>/WEB-INF/FTL/</value>
??? ??? </property>
??? ??? <property name="defaultEncoding">
??? ??? ??? <value>GB2312</value>
??? ??? </property>
??? ??? <property name="freemarkerSettings">
??? ??? ??? <props>
??? ??? ??? ??? <prop key="template_update_delay">3600</prop>
??? ??? ??? </props>
??? ??? </property>
??? </bean>

??? <bean id="welcomeController" class="sprinl.mvc.WelcomeController">
??? ??? <property name="viewName">
??? ??? ??? <value>welcome</value>
??? ??? </property>
??? </bean>

??? <bean id="simpleUrlHandlerMapping"
??? ??? class="org.springframework.web.servlet.handler.SimpleUrlHandlerMapping">
??? ??? <property name="mappings">
??? ??? ??? <props>
??? ??? ??? ??? <prop key="/welcome.ftl">welcomeController</prop>
??? ??? ??? </props>
??? ??? </property>
??? </bean>
</beans>
以及
<?xml version="1.0" encoding="GB2312"?>
<beans xmlns="http://www.springframework.org/schema/beans"
??? xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
??? xmlns:util="http://www.springframework.org/schema/util"
??? xsi:schemaLocation="
??? http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.0.xsd
??? http://www.springframework.org/schema/util http://www.springframework.org/schema/util/spring-util-2.0.xsd">

??? <!-- ===================================================== -->
??? <!--???????????????? ViewResolver For JSP????????????????? -->
??? <!-- ===================================================== -->
??? <bean id="JSPViewResolver"
??? ??? class="org.springframework.web.servlet.view.InternalResourceViewResolver">
??? ??? <property name="divfix">
??? ??? ??? <value>/WEB-INF/JSP/</value>
??? ??? </property>
??? ??? <property name="suffix">
??? ??? ??? <value>.jsp</value>
??? ??? </property>
??? </bean>

??? <bean id="IndexController" class="sprinl.mvc.IndexController">
??? ??? <property name="messages">
??? ??? ??? <value> 我的第一个Spring-View 例子-- 要给我鼓励</value>
??? ??? </property>
??? ??? <property name="page">
??? ??? ??? <value>home</value>
??? ??? </property>
??? </bean>

??? <bean id="divsonController" class="sprinl.mvc.PresonController">
??? ??? <property name="page">
??? ??? ??? <value>divson</value>
??? ??? </property>
??? </bean>

??? <bean id="simpleUrlHandlerMapping"
??? ??? class="org.springframework.web.servlet.handler.SimpleUrlHandlerMapping">
??? ??? <property name="mappings">
??? ??? ??? <props>
??? ??? ??? ??? <prop key="/home.view">IndexController</prop>
??? ??? ??? ??? <prop key="/divson.view">divsonController</prop>
??? ??? ??? </props>
??? ??? </property>
??? </bean>
</beans>

通过上述代码 就可以实现JSP 以及FreeMarker 的合作工作，前提条件是根据後最名称来进行请求的分发
