spring mvc 多视图配置

1、创建MultiViewResover类

package org.pzy.module.result_view.view_resolver;import java.util.Locale;import java.util.Map;import org.springframework.web.servlet.View;import org.springframework.web.servlet.ViewResolver;public class MultiViewResover implements ViewResolver {private Map<String, ViewResolver> resolvers;/** * 默认视图类型为jsp视图 */private static final String DEFAULT_VIEW_TYPE = "jsp";@Overridepublic View resolveViewName(String viewName, Locale locale) throws Exception {int n = viewName.lastIndexOf("_"); // 获取// viewName(modelAndView中的名字)看其有没有下划线String suffix = MultiViewResover.DEFAULT_VIEW_TYPE;// 默认使用jsp视图if (n != -1) {// 有的话截取下划线后面的字符串 这里一般是jsp,ftl,vm与配置文件中的<entry key="ftl">的key匹配suffix = viewName.substring(n + 1);// 取下划线前面的部分 那时真正的资源名.比如我们要使用hello.jsp 那viewName就应该是hello_jspviewName = viewName.substring(0, n);}// 根据下划线后面的字符串去获取托管的视图解析类对象ViewResolver resolver = resolvers.get(suffix);if (resolver != null)return resolver.resolveViewName(viewName, locale);return null;}public Map<String, ViewResolver> getResolvers() {return resolvers;}public void setResolvers(Map<String, ViewResolver> resolvers) {this.resolvers = resolvers;}}

2、配置spring mvc的视图转换规则(dispacher-servlet)

<?xml version="1.0" encoding="UTF-8"?><beans xmlns="http://www.springframework.org/schema/beans"xmlns:mvc="http://www.springframework.org/schema/mvc" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xmlns:p="http://www.springframework.org/schema/p" xmlns:context="http://www.springframework.org/schema/context"xsi:schemaLocation="        http://www.springframework.org/schema/beans         http://www.springframework.org/schema/beans/spring-beans-3.0.xsd        http://www.springframework.org/schema/context         http://www.springframework.org/schema/context/spring-context-3.0.xsd        http://www.springframework.org/schema/mvc         http://www.springframework.org/schema/mvc/spring-mvc-3.0.xsd"><mvc:annotation-driven /><context:component-scan base-package="org.pzy" /><mvc:resources location="/resources/" mapping="/resources/**" /><bean id="velocityConfig"class="org.springframework.web.servlet.view.velocity.VelocityConfigurer"><!-- Velocity模版文件存放路径(spring mvc会在该路径下寻找) --><property name="resourceLoaderPath" value="/WEB-INF/vm" /><!-- Velocity配置文件 --><property name="configLocation" value="classpath:velocity/velocity.properties" /></bean><bean id="viewResolver"class="org.pzy.module.result_view.view_resolver.MultiViewResover"><property name="resolvers"><map><entry key="jsp"><beanclass="org.springframework.web.servlet.view.InternalResourceViewResolver"><property name="viewClass"value="org.springframework.web.servlet.view.JstlView" /><property name="prefix" value="/" /><property name="suffix" value=".jsp" /></bean></entry><entry key="ftl"><beanclass="org.springframework.web.servlet.view.freemarker.FreeMarkerViewResolver"><property name="cache" value="true" /><property name="prefix" value="/" /><property name="suffix" value=".ftl" /></bean></entry><entry key="vm"><beanclass="org.springframework.web.servlet.view.velocity.VelocityViewResolver"><property name="cache" value="true" /><property name="prefix" value="/" /><property name="suffix" value=".vm" /></bean></entry></map></property></bean></beans>

3、编写测试controller类

package org.pzy.module.result_view.controller;import java.util.Map;import org.springframework.stereotype.Controller;import org.springframework.web.bind.annotation.PathVariable;import org.springframework.web.bind.annotation.RequestMapping;import org.springframework.web.bind.annotation.RequestMethod;@Controller@RequestMapping("index")public class IndexController {@RequestMapping(value = { "/test/{test}" }, method = RequestMethod.GET)public String test(@PathVariable String test, Map<String, Object> result) {result.put("flag", test);// 不加任何后缀，使用jsp视图return "index";// 使用jsp视图// return "index_jsp" ;// 使用velocity视图// return "index_vm";// 使用freemark视图// return "index_ftl"}}

4、分别编写velocity/freemark/jsp的测试页面，测试效果
