Struts2学习系列 -- Struts2增加json插件2 + ajax请求
主要jar包：
springframework 3.1.1版本
struts2 2.3.4.1版本
其他
js包：
jquery.ms.js
Domain
Device2.java：
public class Device2 {
private String deviceId;
private String userName;
private String pwd;
private String netAddr;
private String netPort;
// set/get方法略
}
Action类：
@Component
@Scope("prototype")
@SuppressWarnings("serial")
public class MyAction extends ActionSupport{
private Device2 device;
private Integer id;
private String result;
public String add3(){
System.out.println("add3");
System.out.println(device);
// result = "{name:pxj, password:'登录成功!'}";
result = device.toString();
return SUCCESS;
}
// set/get方法略
}
struct.xml重点配置如下
<package name="struts3" extends="struts-default,json-default" namespace="/">
<action name="myAction3" class="myAction" method="add3">
<result type="json">
<param name="root">result</param>
</result>
</action>
</package>
包必须继承json-default。
result的type为json，其中root参数的值result表示将对应action中属性为result属性值返回给客户端。
jsp页面：
<form action="myAction3" method="post"> 设备id：<input type="text" name="deviceId3" id="deviceId3" /><br> 登陆账号：<input type="text" name="userName3" id="userName3" /> <br> 登陆密码：<input type="text" name="pwd3" id="pwd3" /> <br> <input type="button" onclick="onclickSave()" value="提交" /> <div id="info"></div> </form>
js代码如下：
<script src="jquery/jquery.min.js" type="text/javascript"></script>
<script>
function onclickSave()
{
$.post('myAction3',
{
"device.deviceId":$('#deviceId3')[0].value,
"device.userName":$('#userName3')[0].value,
"device.pwd":$('#pwd3')[0].value
// loginName:$('#userName2')[0].value,
// loginPwd:$('#pwd2')[0].value
},
function(data){
alert(data);//请求返回的内容
},'json');
}
</script>
