主要用到的是<input>的multiple属性
复制代码代码如下:
<input type="file" name="multipleFileUpload" multiple />
下面是页面的详细代码：
复制代码代码如下:
<!DOCTYPE html>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=gb2312" />
<title>Solution 4-5: Sending multiple files</title>
</head>
<body>
<form id="myForm"
action="http://10.10.25.31:8080/myupload/UploadPhotoServlet" ENCTYPE="multipart/form-data" METHOD="POST">
<input type="file" name="multipleFileUpload" multiple /> <input
type="submit" value="提交"> <input type="reset" value="重设">
</form>
</body>
</html>
java后台的详细代码：

String fileName=null;
try {

if(list.size()<1){

if(fileName.equals("")){
request.getRequestDispatcher("/com/visualizerPhoto.jsp").forward(request, response);
return;
}
int pos=fileName.lastIndexOf(".");//取图片文件格式
if(pos>0){
Date date=new Date();
fileName=imagePath+date.getTime()+fileName.substring(pos);
}
System.out.println("item:"+item);
item.write(new File(fileName));//写到磁盘

}
// 13-11-15
public static String getEachDate() {
Calendar cal = Calendar.getInstance();
cal.add(Calendar.DATE, 0);
String yesterday = new SimpleDateFormat("yyyy-MM-dd ").format(cal
.getTime());
String[] dates = yesterday.split("-");
String realDate = dates[0].substring(2, 4) + "-" + dates[1] + "-"
+ dates[2];
return realDate.trim();
}
}
下面是效果图：
