简单的JQuery(AJAX)+SpringMVC的小例子(JSON)
简单的JQuery(AJAX)+SpringMVC的小例子，实现将对象以JSON的形式返回给页面。
(本例包含一个HelloWorld，一个表单参数传递，一个JSON实例)
如有时间可以在http://www.verycd.com/topics/2917293/下载相关视频。

目录结构：


1.相关Jar包的引入，spring的jar包,jstl的jar包特别是jaskson相关的两个jar包

2.web.xml配置：

<?xml version="1.0" encoding="UTF-8"?>
<web-app version="2.5" 
	xmlns="http://java.sun.com/xml/ns/javaee" 
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
	xsi:schemaLocation="http://java.sun.com/xml/ns/javaee 
	http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd">
  <welcome-file-list>
    <welcome-file>index.jsp</welcome-file>
  </welcome-file-list>
  
  <servlet>
  	<servlet-name>springmvc</servlet-name>
  	<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
  </servlet>
  
  <servlet-mapping>
  	<servlet-name>springmvc</servlet-name>
  	<url-pattern>*.do</url-pattern>
  </servlet-mapping>
  
  	<context-param>
		<param-name>contextConfigLocation</param-name>
		<param-value>/WEB-INF/springmvc-servlet.xml</param-value>
	</context-param>

	<listener>
		<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
	</listener>
  
</web-app>

2.根据web.xml的配置,创建对应的xxxx-servlet.xml文件
这里是springmvc-servlet.xml

<?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:tx="http://www.springframework.org/schema/tx"
	xmlns:mvc="http://www.springframework.org/schema/mvc"
	xsi:schemaLocation="http://www.springframework.org/schema/beans
           http://www.springframework.org/schema/beans/spring-beans-3.0.xsd
           http://www.springframework.org/schema/context
           http://www.springframework.org/schema/context/spring-context-2.5.xsd
           http://www.springframework.org/schema/tx 
     	   http://www.springframework.org/schema/tx/spring-tx-3.0.xsd
     	   http://www.springframework.org/schema/mvc
           http://www.springframework.org/schema/mvc/spring-mvc-3.0.xsd">

	<context:component-scan base-package="com.mvc"></context:component-scan>
	<mvc:annotation-driven />
	<bean id="viewResolver"
		class="org.springframework.web.servlet.view.UrlBasedViewResolver">
		<property name="viewClass"
			value="org.springframework.web.servlet.view.JstlView"></property>
		<property name="prefix" value="/"></property>
		<property name="suffix" value=".jsp"></property>
	</bean>
	
</beans>

3.Model类的编写

public class Shop {

	String name;
	
	String staffName[];
	public String getName() {
		return name;
	}
	public void setName(String name) {
		this.name = name;
	}
	public String[] getStaffName() {
		return staffName;
	}
	public void setStaffName(String[] staffName) {
		this.staffName = staffName;
	}
	public Shop() {
	} 
	
}

4.Controller的编写

@Controller
public class JSONController {

	@RequestMapping(value="/json", method = RequestMethod.GET)
	public @ResponseBody Shop getShopInJSON() {

		//测试数据
		Shop shop = new Shop();
		System.out.println("Shop");
		shop.setName("Eric");
		shop.setStaffName(new String[]{"mkyong1", "mkyong2"});
		
		return shop;

	}
	
}

5.jsp中的ajax代码：

<script type="text/javascript" src="jquery-1.7.2.min.js">
</script>
<script type="text/javascript">
$(function() {
	getjson();
});

function getjson() {
	$.ajax( {
		type : "get
