在網(wǎng)上看到許多上傳文件的例子，可是都是jsp程序，每碰到需要文件上傳的地方就要復(fù)制這段上傳代碼并做相應(yīng)修改，維護(hù)起來(lái)極不方便。為了增強(qiáng)代碼的可重用性，我將這段通用的上傳程序?qū)懗闪?a href="http://m.survivalescaperooms.com/article.asp?typeid=160">javaBean，請(qǐng)大家多提意見(jiàn)。

首先，下載 commons-fileupload-1.0.zip 和 commons-beanutils-1.7.0.zip,

http://apache.freelamp.com/jakarta/commons/fileupload/binaries/commons-fileupload-1.0.zip
http://apache.freelamp.com/jakarta/commons/beanutils/binaries/commons-beanutils-1.7.0.zip

解壓縮得到 commons-fileupload-1.0-beta-1.jar 和commons-beanutils.jar, 并將兩個(gè)包放到 "YourWebApp/WEB-INF/lib"文件夾下。

UploadFile.java
