下面是js 和后台java完整代码：
function uploadImage()
{
uuid = new UUID().createUUID();
var fileName = $("#videoImage").val();
var array1=fileName.split(".");
if(array1[array1.length-1]=="jpg"||array1[array1.length-1]=="JPG")
{
$.ajaxFileUpload({
url:‘upload!uploadImage.action‘,
secureuri:false,
files:[$(‘#videoImage‘)],
dataType: ‘json‘,
global: false,
data:{"videoImageFileName1":uuid+"."+array1[1],"uuid":uuid},
complete:function()
{
// alert("上传成功");
$("#image").attr("src","tem/"+username+"/"+uuid+"."+array1[1]+".jpg?"+Math.random());
$("#xttp").attr("src","tem/"+username+"/"+uuid+"."+array1[1]+".jpg?"+Math.random());
$("#picName").val(fileName);
$("#lla").html(fileName);
//$("#videoImage").replaceWith(‘<input type="file" name="videoImage" style="width: 455px" id="videoImage" onchange="uploadImage()" class="uplod" />‘);
}
});
}else
{
alert(‘请选择jpg图片‘);
}
}
//ftp 上传
private boolean ftpUpLoad(String ip, String userName, String password,
File srcFile, String directory) {
boolean res = false;
FTPClient ftpClient = new FTPClient();//ftp客户端
try {
int indexOf = directory.indexOf("/");
String user = directory.substring(0, indexOf);//获取上传路径
String md5Str = directory.substring(indexOf + 1);
ftpClient.connect(ip);//根据ip创建连接
boolean r0 = ftpClient.login(userName, password);//ftp登录
boolean r1 = ftpClient.makeDirectory("/img/" + user);//ftp创建文件夹
boolean r2 = ftpClient.makeDirectory("/img/" + user + "/"+ md5Str);//ftp创建加密文件夹
