在spring MVC中配置多个视图

如果在一个项目中有人比较喜欢用freemarker,而有人对JSTL（Jsp标准标记库）比较熟，那就得配置多种视图的方式！
１.首先在web.xml，配置多个Dispatcher，不同视图当然转发不一样！

web.xml

<servlet-name>fm</servlet-name>
<servlet-class>
org.springframework.web.servlet.DispatcherServlet
</servlet-class>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>jstl</servlet-name>
<url-pattern>/*.do</url-pattern>
</servlet-mapping>
<servlet-mapping>
<servlet-name>fm</servlet-name>
<url-pattern>/*.fm</url-pattern>
</servlet-mapping>
<servlet>

２.然后再配置*-servlet文件

jstl-servlet.xml

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN//EN" "http://www./dtd/spring-beans.dtd">
<beans>
<bean id="simpleUrlHandlerMapping" class="org.springframework.web.servlet.handler.SimpleUrlHandlerMapping">
<property name="mappings">
<props>
<prop key="/hello.do">showCon</prop>
</props>
</property>
</bean>
<bean name="showCon" class="test.mvc.web.ShowController"/>
<bean id="viewResolver"
class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="prefix"><value>/WEB-INF/template/jsp/</value></property>
<property name="suffix"><value>.jsp</value></property>
<property name="viewClass">
<value>org.springframework.web.servlet.view.JstlView</value>
</property>
</bean>
</beans>

fm-servlet.xml

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN//EN" "http://www./dtd/spring-beans.dtd">
<beans>
<bean id="simpleUrlHandlerMapping" class="org.springframework.web.servlet.handler.SimpleUrlHandlerMapping">
<property name="mappings">
<props>
<prop key="/hello.fm">showCon</prop>
</props>
</property>
</bean>
<bean name="showCon" class="test.mvc.web.ShowController"/>
<bean id="viewResolver" class="org.springframework.web.servlet.view.freemarker.FreeMarkerViewResolver">
<property name="suffix"><value>.fm</value></property>
<property name="viewClass">
<value>org.springframework.web.servlet.view.freemarker.FreeMarkerView</value>
</property>
<property name="contentType"><value>text/html; charset=gb2312</value></property>
</bean>
</beans>

两个视图都调用test.mvc.web.ShowController，所以即使全部换了视图层，也不影响到控制层的东西，这就是spring MVC强大之一！
