编程中遇到的因脑残造成的错误--struts2（2016/7/14）

1、struts.xml与页面url不匹配

     struts.xml

<action name="eg4Action_*" class="demo02.Eg04Action" method="{1}"></action>

     index4.html

function showPic(){
$("#form").ajaxSubmit({
type: "post",
url: "eg04Action_showPic.action",
cache: false,
dataType:"text",
success:function(data){
$("#img").attr("src","upload/"+data);
}
});
}

    错误信息

WARNING: Could not find action or result
There is no Action mapped for namespace [/] and action name [eg04Action_showPic] associated with context path [/20160713]. - [unknown location]
