上传文件
文件上传
采用struts上传文件
* 页面的配置，如：
<form action="upload.do" method="post" enctype="multipart/form-data">
标题：<input type="text" name="title"><br>
文件：<input type="file" name="myfile"><br>
<input type="submit" value="提交">
</form>
* ActionForm中使用FormFile来接收上传的文件
* 在Action中调用FormFile取得上传文件数据，采用流输出，即完成上传
* 在struts-config.xml中采用<controller/>标签配置上传参数，在<action-mappings>标签后边，如：<controller maxFileSize="10M"/>
