如何获取form表单下file的路径

确认：

1.是以post方式提交的的吗

2.有无 ：enctype= "multipart/form-data "

表单上传如果不加enctype= "multipart/form-data "，上传文件时使用默前游认编码application/x-www-form-urlencoded，不能用于文件上传，而添加后设置编码为MIME编码才能完整纯悔历上传。还有就是天加了enctype= "multipart/form-data "不能使用request.getParameter("fileName")来获取表单元做搜素

<form action="" method="post">

<input type="file" name="file1"/态胡孙>

</form>

request.getParameter("file1"帆链)

<form action="做型" method="post" enctype="multipart/form-data">

<input type="file" name="file1"/>

</form>

ServletInputStream sis = request.getInputStream()

用sis读取,一行一行分析.
