组建Jquery+Spring3 MVC架构的尝试_jquery+spring 系统架构-优快云博客

本文介绍了一个使用Spring MVC框架处理JSON数据的简单示例。通过CustomerController类实现了一个POST请求，接收并修改Customer对象的数据，再将其返回。前端采用jQuery发起AJAX请求，并展示响应结果。

看完上面的文章深受启发，于是先尝试着把上文中的工程搭建起来.

代码如下：

CustomerController.java

package com.jqweb.action; import org.springframework.stereotype.Controller; import org.springframework.web.bind.annotation.RequestBody; import org.springframework.web.bind.annotation.RequestMapping; import org.springframework.web.bind.annotation.RequestMethod; import org.springframework.web.bind.annotation.ResponseBody; import com.jqweb.model.Customer; @Controller @RequestMapping("/customerInfo") public class CustomerController { @RequestMapping(value = "/new", method = RequestMethod.POST) @ResponseBody public Customer newCustomer(@RequestBody Customer customer) { customer.setName(customer.getName() + "shenbin"); customer.setAddr(customer.getAddr() + "kunshan"); return customer; } }

Customer.java

package com.jqweb.model; import java.io.Serializable; public class Customer implements Serializable { private static final long serialVersionUID = 6661953752626765129L; private String name; private String addr; public String getName() { return name; } public void setName(String name) { this.name = name; } public String getAddr() { return addr; } public void setAddr(String addr) { this.addr = addr; } }

jqWeb-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:p="http://www.springframework.org/schema/p" xmlns:util="http://www.springframework.org/schema/util" xmlns:context="http://www.springframework.org/schema/context" xsi:schemaLocation=" http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.5.xsd http://www.springframework.org/schema/util http://www.springframework.org/schema/util/spring-util-2.5.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-2.5.xsd"> <context:component-scan base-package="com.jqweb.action"/> <bean class="org.springframework.web.servlet.mvc.annotation.DefaultAnnotationHandlerMapping"/> <bean class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter"> <property name="messageConverters"> <util:list id="beanList"> <ref bean="mappingJacksonHttpMessageConverter" /> </util:list> </property> </bean> <bean id="mappingJacksonHttpMessageConverter" class="org.springframework.http.converter.json.MappingJacksonHttpMessageConverter" /> </beans>

web.xml

<?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"> <servlet> <servlet-name>jqWeb</servlet-name> <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> <load-on-startup>1</load-on-startup> </servlet> <servlet-mapping> <servlet-name>jqWeb</servlet-name> <url-pattern>*.do</url-pattern> </servlet-mapping> <welcome-file-list> <welcome-file>index.jsp</welcome-file> </welcome-file-list> </web-app>

index.jsp

注：

以上使用的是Spring3.0.1版本。

Jackson JSON Processor下载地址：http://jackson.codehaus.org/

json2下载地址：http://www.json.org/js.html

下来发现在Spring3.0.2版本下最新的Jackson JSON Processor版本不能正常工作，参见：http://jira.springframework.org/browse/SPR-7063?page=com.atlassian.jira.plugin.system.issuetabpanels%3Achangehistory-tabpanel

解决等办法是等待Spring3的下一个子版本，或者如上图所示使用低版本的Jackson JSON Processor.
