出现这个错误

是因为你没有正确josn数据的返回视图，在struts2中的配置如下：

<action name="acorder!*" class="orderinfo" method="{1}">
        <result type="json" name="jsonok">
            <param name="root">json</param>
        </result>
        <result type="redirect" name="success">admin/Allfenlei.jsp?iden=orderok</result>
</action>

type应该是json，而参数root的值就是我们的json数组或json对象
