spring　mvc配置文件：

<?xml version="1.0" encoding="UTF-8"?><beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:context="http://www.springframework.org/schema/context" xmlns:mvc="http://www.springframework.org/schema/mvc"xsi:schemaLocation="http://www.springframework.org/schema/beans   http://www.springframework.org/schema/beans/spring-beans.xsd                           http://www.springframework.org/schema/context                           http://www.springframework.org/schema/context/spring-context.xsd                           http://www.springframework.org/schema/mvc                           http://www.springframework.org/schema/mvc/spring-mvc.xsd"><mvc:annotation-driven  content-negotiation-manager="contentNegotiationManager"/><mvc:view-controller path="/" view-name="index"/><bean id="contentNegotiationManager" class="org.springframework.web.accept.ContentNegotiationManagerFactoryBean"><property name="mediaTypes"><value>html=text/htmljson=application/json</value></property><property name="defaultContentType" value="text/html"/></bean><bean class="org.springframework.web.servlet.view.ContentNegotiatingViewResolver"><property name="order" value="0"/><property name="contentNegotiationManager" ref="contentNegotiationManager"/><property name="viewResolvers"><list><bean class="org.springframework.web.servlet.view.InternalResourceViewResolver"><property name="viewClass" value="org.springframework.web.servlet.view.JstlView"/><property name="prefix" value="/WEB-INF/jsp/"/><property name="suffix" value=".jsp"></property></bean></list></property><property name="defaultViews"><list><bean class="com.alibaba.fastjson.support.spring.FastJsonJsonView"><property name="charset" value="UTF-8"/></bean></list></property></bean><bean class="com.alibaba.fastjson.support.spring.FastJsonHttpMessageConverter"/></beans>

写个测试controller

package com.doctor.springframework.web.view;import java.util.HashMap;import java.util.Map;import org.springframework.stereotype.Controller;import org.springframework.web.bind.annotation.RequestMapping;import org.springframework.web.servlet.ModelAndView;  @Controllerpublic class SimpleController {@RequestMapping({"/test.html","/test.json"})public ModelAndView test() {Map<String, String> map = new HashMap<>();map.put("test", "json");map.put("test-html", "html");map.put("what", "what");ModelAndView modelAndView = new ModelAndView("/contentViewTest");modelAndView.addObject(map);return modelAndView;}}

测试代码：

package com.doctor.springframework.web.view;import org.apache.http.client.fluent.Request;import org.apache.http.client.fluent.Response;import org.junit.After;import org.junit.Before;import org.junit.Test;import com.doctor.embeddedjetty.EmbeddedJettyServer3;/** * ContentNegotiatingViewResolverPractice 根据路径后缀，选择不同视图 * @author doctor * * @time   2015年1月7日 上午10:08:24 */public class ContentNegotiatingViewResolverPractice2 {private EmbeddedJettyServer3 embeddedJettyServer;private int port;@Beforepublic void init() throws Throwable {port = 8989;embeddedJettyServer = new EmbeddedJettyServer3(port,"/contentNegotiatingViewResolverPractice/webapp", SpringContextConfig.class, SpringMvcConfig2.class);embeddedJettyServer.start();}@Testpublic void test() throws Throwable {Response response = Request.Get("http://localhost:8989/test.json").execute();System.out.println(response.returnContent().asString());response = Request.Get("http://localhost:8989/test.html").execute();System.out.println(response.returnContent().asString());response = Request.Get("http://localhost:8989").execute();System.out.println(response.returnContent().asString());}@Afterpublic void destroy() throws Throwable {embeddedJettyServer.stop();}}

输出内容：

01-10 10:18:40.513 main  INFO  o.e.j.s.Server -Started @4908ms{"hashMap":{"test":"json","test-html":"html","what":"what"}}<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"><html><head><meta http-equiv="Content-Type" content="text/html; charset=UTF-8"><title>Insert title here</title></head><body>hello contentNegotiatingViewResolverTest</body></html><html><body><h2>Hello World! doctor</h2></body></html>
