最近一个基于Struts的项目中要用到上传多张图片到系统中，我在网上找了一下，发现大多数都是转载的例子，对项目的作用不大，故写下了这个例子，希望对有用到的朋友有所帮助。要求JDK1.5以上，lib库要包含如下jar文件：antlr.jar，commons-beanutils.jar，commons-collections.jar，commons-digester.jar，commons-fileupload.jar，commons-logging.jar，commons-validator.jar，jakarta-oro.jar，struts.jar这些都是Struts中的jar文件以及Struts中的标签库文件。
