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>
