sturst2+json的action属性较多时指定返回指定数据

action:

private String commonStr;
	public String getCommonStr() {
		return commonStr;
	}         /**
	 * 获取常用消息
	 */
	public String doGetCommonMsg(){
		.....
	         commonStr = ....
		return "commonMsg";
	}

sturst2.xml(json的配置文件)

设置 param：includeProperties

<result type="json" name="commonMsg">
<param name="includeProperties">

commonStr
</param>
</result>



注：如果commonStr为数组 则需要用正则变达式，

<result type="json" name="commonMsg">
<param name="includeProperties">

commonStr/[/d+/]
</param>
</result>
