以`login!blogin.action`动态访问调用action时报错

解决方法：在struts.xml中加上允许动态声明：

该语句表示允许调用动态方法。

jsp的action写法：namespace名+action名!方法名：

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

ajax的action动态调用：

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