java.io.IOException: Corrupt form data: premature ending

来源：互联网发布：旅行者一号知乎编辑：程序博客网时间：2024/05/29 07:37

Cos1.3.1+Struts1.2->放在纯jsp里是可以的,但是放在Struts1.2的action中就有问题了,要求解决方案.如果换一中lib,必须处理多个file request,请明示.

<form name="form_attach_add" method="post"

enctype="multipart/form-data"

action="<%=path%>/addNodeAttach.do">

<input name="nodeTitle" type="hidden"

value="<%=nodeTitle%>">

<table width="100%" border="1" cellpadding="5"

cellspacing="0" bordercolor="#999999"

style="border-collapse: collapse" align="center">

附件：

</td>

<input type="file" name="attachFile" size="40"

required class="input">

</td>

</tr>

<table width="100%" border="0" cellspacing="0"

cellpadding="0">

<tr>

<input type="Button" value="增加"

onclick="button_validate(this.form)" class=input />

<input type="reset" name="reset" value="清空"

class="input">

</td>

</tr>

</table>

</td>

</tr>

</table>

</form>

public NodeAttach evaluate() throws FileNotFoundException, IOException {

NodeAttach na = new NodeAttach();

int maxPostSize = 3 * 5 * 1024 * 1024;

MultipartRequest mr = new MultipartRequest(ActionContext

.getActionContext().getRequest(), "D:/", maxPostSize, "gb2312");

// 输出反馈信息

Enumeration files = mr.getFileNames();

while (files.hasMoreElements()) {

String filePath = (String) files.nextElement();

System.out.println("filePath:" + filePath);

File file = mr.getFile(filePath);

if (file != null) {

String fileName = file.getName();

// 创建输入数据流

FileInputStream fis = new FileInputStream(file);

// 创建输出数据流

String newFileName = System.currentTimeMillis() + "."

+ FileU.getFilePostfix(fileName);

FileOutputStream fos = new FileOutputStream(getSaveDir() + "/"

+ newFileName);

int bytesRead = 0;

byte[] buffer = new byte[8192];

while ((bytesRead = fis.read(buffer, 0, buffer.length)) != -1) {

fos.write(buffer, 0, bytesRead);

}

na.setAttachFile(newFileName);

na.setAttachName(fileName);

na.setAttachSize((int) file.length());

na.setAttachType(mr.getContentType(filePath));

}

return na;

}

异常:
