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)@ResponseBodypublic 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

index.jsp

<html><head><script type="text/javascript" src="js/jquery-1.4.2.js"></script><script type="text/javascript" src="js/json2.js"></script><script type="text/javascript"><!--function save() {var elemUserinfo = $('#customerInfo');var userinfo = elemUserinfo.serializeObject();  var jsonuserinfo = JSON.stringify(userinfo);jQuery.ajax({type : 'POST',contentType : 'application/json',url : 'customerInfo/new.do',data : jsonuserinfo,dataType : 'json',success : function(data){$('div#responseName').text(data.name);  $('div#responseAddr').text(data.addr);  },error : function(data){alert(data);}});  }$.fn.serializeObject = function() {      var o = {};  var a = this.serializeArray();    $.each(a, function() {          if (o[this.name]) {              if (!o[this.name].push) {                  o[this.name] = [ o[this.name] ];              }              o[this.name].push(this.value || '');          } else {              o[this.name] = this.value || '';          }      });      return o;  };// --></script></head><body><form id="customerInfo"><input name="name" type="text" value="123"><input name="addr" type="text" value="234"></form><br><input type="button" value="test" onclick="save()"><br><div id="responseName"></div><div id="responseAddr"></div></body></html>

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
