struts上传文件
Struts的文件上传
本文用的是Struts1.1的org.apache.struts.upload.FormFile类。很方便，不用自己写。也不用写一个jsp调用jspsmartupload就可以搞定。
选择上传文件页面：selfile.jsp
<%@ taglib uri="/WEB-INF/struts-html.tld" prefix="html"%>
<html:html>
<html:form action="/uploadsAction.do" enctype="multipart/form-data">
<html:file property="theFile"/>
<html:submit/>
</html:form>
</html:html>
最近刚做完一个项目，用Struts1.1做的。从不懂，到熟练使用，都靠参考优快云的一些文档。但是文章上讲的并不一定适合自己，所以我把我自己做的一些东西拿上来给大家看看，互相交流一下。如果您有跟好的方法，可以和我联系。
