xmlns:context=\"http://www.springframework.org/schema/context\"

xmlns:util=\"http://www.springframework.org/schema/util\" xmlns:mvc=\"http://www.springframework.org/schema/mvc\"

xsi:schemaLocation=\"http://www.springframework.org/schema/beans

http://www.springframework.org/schema/beans/spring-beans-3.2.xsd

http://www.springframework.org/schema/context

http://www.springframework.org/schema/context/spring-context-3.2.xsd

http://www.springframework.org/schema/util

http://www.springframework.org/schema/util/spring-util-3.2.xsd http://www.springframework.org/schema/mvc

http://www.springframework.org/schema/mvc/spring-mvc-3.2.xsd\">

class=\"org.springframework.web.servlet.view.InternalResourceViewResolver\"

id=\"internalResourceViewResolver\">

加入WEB依赖和json依赖。

org.springframework spring-web 4.3.7.RELEASE

org.springframework spring-webmvc 4.3.7.RELEASE

com.fasterxml.jackson.core jackson-databind 2.8.5

添加类

package com.test.smvc.control;

import java.util.Date; import java.util.HashMap;

import org.springframework.stereotype.Controller;

import org.springframework.web.bind.annotation.RequestMapping; import org.springframework.web.bind.annotation.ResponseBody; import org.springframework.web.servlet.ModelAndView;

@Controller

@RequestMapping(\"/mvc\") publicclass Test {

@RequestMapping(\"/hello\") public String hello() { return\"hello\"; }

@RequestMapping(\"/hello1\")

public ModelAndView hello1() {

ModelAndView modelAndView = new ModelAndView(); modelAndView.addObject(\"name\", new Date());

modelAndView.addObject(\"namexx\", new Object()); modelAndView.setViewName(\"hello\"); returnmodelAndView; }

@RequestMapping(\"/hello2\") @ResponseBody

public HashMap hello2() { HashMapmap = new HashMap(); map.put(\"kkkk\", \"vvvv\"); returnmap; } }

添加JSP页面到WebContent/WEB-INF/jsp/hello.jsp

配置启动服务。

访问地址：如下，说明成功。
