struts2+json配置方式和jar包

Struts2.0的Action

Struts2.0的xml

 

 

 

注:只会返回list的json格式

<?xml version="1.0" encoding="UTF-8" ?>

<!DOCTYPE struts PUBLIC
 "-//Apache Software Foundation//DTD Struts Configuration 2.0//EN"
 "http://struts.apache.org/dtds/struts-2.0.dtd">

<struts>
 <package name="AddCartAction" namespace="" extends="json-default">

<!-- 备选地址列表 

配置多个对象时要注意按action对象的前后循序摆放,如果是boolean类型的不管你的变量名开头字母是大写还是小写,这里配置都要写小写的

-->
 <action name="addCartAddressList" class="unite.action.index.AddCartAction" method="addCartAddressList">

 </result>
 </action>

</package>
</struts>

 


jquery的ajax调用函数

$.ajax({
 type: "POST", //请求方式
 async: false,
 url: "addCartAddressList.action",
 dataType: "json",
 data: {
 randoms: Math.random(),
 key : values,
 sumintegral : $("#Point").text(),
 sumPrice :$("#ItemAmount").text()
 },
 success: function(data) {
 if(data)
 {
// var a= eval('('+data+')');
// var b=a['list'];
 alert(data.list[0].udid);
 //location.href="/users/consigneeAddress1.jsp";
 }else
 {
 //结账失败,可能是您的账号已经注销或未登录！
 alert("\u7ED3\u8D26\u5931\u8D25,\u53EF\u80FD\u662F\u60A8\u7684\u8D26\u53F7\u5DF2\u7ECF\u6CE8\u9500\u6216\u672A\u767B\u5F55\uFF01");
 }
 },
 error: function(e) {
 //服务器连接失败！
 alert("\u670D\u52A1\u5668\u8FDE\u63A5\u5931\u8D25\uFF01");
 }
 });
