xheditor struts2 上传文件

注意，上传图片可能会显示不出来（如果你没放在tomcat的webapps目录下），这是由于上传图片时是默认上传到tomcat的目录下！！！

1. jsp页面

<textarea name="editor1" style="width:100%;min-height: 400px;" id="xheditor"></textarea>                   
        <script type="text/javascript">

            $(function(){
                $('#xheditor').xheditor({
                    tools:'Img',
                    skin:'vista',
                    html5Upload : false, //此属性必须为false 否则无法上传图片 
                    onUpload : uploadImg,   
                    upImgUrl:"${pageContext.request.contextPath}/plan/preplan/preplan_picture_uploadImg.action",//action请自己配置
                    upImgExt:"jpg,jpeg,gif,png"
                }); 
                function uploadImg(data) {  
                    //...回调函数  
                } 

            })
  </script>             

2. strust.xml配置（action的名字请自己配置）

        <!-- Picture拦截和结果配置 -->
        <action name="preplan_picture_*" class="com.gsafety.plan.module.actions.PictureAction" method="{1}">
            <result name="jsonObject" type="json">
                <!-- 为该Result指定参数 -->
                <param name="noCache">true</param>
                <param name="contentType">text/html</param>
                <!-- 设置只序列Action的map属性 -->
                <param name="root">jsonObject</param>
            </result>           
            <result name="jsonArray" type="json">
                <!-- 为该Result指定参数 -->
                <param name="noCache">true</param>
                <param name="contentType">text/html</param>
                <!-- 设置只序列Action的map属性 -->
                <param name="root">jsonArray</param>
            </result>                       
        </action>
