if(isYes){
//构建文件目录及文件
File file = new File(savePath);
if(!file.exists()){
file.mkdirs();
}
//创建一个File
// File file = new File(savePath + "\\" + name);
try {
//重命名文件
// String filename = UUID.randomUUID().toString();
String filename = new Date().getTime()+"" ;
File savefile = new File(savePath + filename +"."+ extension);
//写入文件
item.write(savefile);
savePathName = savefile.getPath();
//截取路径，删掉前面的tomcat路径 fcgcredit 改SQL
//int l = savePathName.lastIndexOf("nnxdcredit");
int l = savePathName.lastIndexOf("fcgcredit"); //第169行
savePathName = savePathName.substring(l,savePathName.length());
//增加'/'
savePathName = "/"+savePathName;
//转换'/'
savePathName = savePathName.replace("\\", "/");
//如果是信用表格上传，则保存路径
