我只是想在JSP中使用表单上传图像,因为我编写了一个代码,按照下面的代码,它不是插入while循环。结果图像未上传到目录中。
你能帮忙解决问题吗?
html代码
<html>
<head><title>Upload page</title></head></p> <p><body>
<form action="upload_jsp.jsp" method="post" enctype="multipart/form-data" name="form1" id="form1">
<center>
<table border="2">
<tr>
<td align="center"><b>Multipale file Uploade</td>
</tr>
<tr>
<td>
Specify file: <input name="file" type="file" id="file">
<td>
</tr>
<tr>
<td>
Specify file:<input name="file" type="file" id="file">
</td>
<tr>
<td>
Specify file:<input name="file" type="file" id="file">
</td>
</tr>
<tr>
<td align="center">
<input type="submit" name="Submit" value="Submit files"/>
</td>
</tr>
</table>
<center>
</form>
</body>
</html>

答案 0 :(得分:0)
这是可能有问题的代码行,因为item.getName()将返回源文件所在的完整路径。这可能会导致格式错误的文件路径。
尝试更换:
String itemName = item.getName();
使用:
String itemName = FilenameUtils.getName(item.getName());
确保导入了FilenameUtils:
<%@ page import="org.apache.commons.io.FilenameUtils" %>
您的网络应用程序库中有 commons-io.jar 。
