struts2 解决上传问题

记录下最近接触的用struct上传文件的方法。

 

• html

符号表：<input type="file" id="fhb" name="binfile" style="cursor:pointer;" onchange="fileChange(this,'fhb');"/>
bin文件：<input type="file" id="bin" name="binfile" style="cursor:pointer;" onchange="fileChange(this,'bin');"/>

补丁文件：<input type="file" id="bdwj1" name="upload" style="cursor:pointer;" onchange="fileChange(this,'bdwj1');"/>

 

•   action

	private static final int NUM = 8192;

	// 补丁文件

• 为了明了其中蹊跷，debug跟了下其中的值
• 补丁文件上传了名为test.txt, test2.txt的文本文件
• 符号表和bin文件上传了名为st.txt, bin.txt的文本文件
