解決方法：在struts.xml中加上允許動態聲明：

<constant name="struts.enable.DynamicMethodInvocation" value="true" />

該語句表示允許調用動態方法。

jsp的action寫法：namespace名+action名!方法名：

<s:form action="login!blogin" method="post">

ajax的action動態調用：

$.ajax({
		url : "login!blogin.action",
		type : "post",
		dataType : "json",
		data : params,
		async : false,
		success : function(result) {	
			alert("Success！");	
		}
	});
