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>
