我不知道这里是否有人使用Spring框架提供的 FileCopyUtils ，但我在我的系统中使用了图像的复制方法。它的目标是捕捉＆＃34;我系统的临时文件夹中的图像并复制到服务器上的另一个文件夹。下面是一些评论的方法：
public Set<Image> imageReplication(String destination) throws IOException {
Set<Image> img = new HashSet<>();
Image image =null;
try {
List<ImageJson> imagePathTmpList = dashboardFacade.getImagePathTmpList();
Gson gson = null;
String subdomain = dashboardFacade.getAgency().getSubdomain();
File base = new File("/home/manolo/joocebox-img/" + subdomain + "/"+ destination);
for (ImageJson imageJsonList : imagePathTmpList) {
gson = new Gson();
image = new Image();
FileMeta imgTmp = gson.fromJson(imageJsonList.getJson(), FileMeta.class);
//File Old path
String oldPath = imgTmp.getFileTmpPath();
//New File Path
String newPath = base + "/" + imgTmp.getFileName();
//Checks if the base directory exists, if not it creates the path and makes copies of the files. I believe here that trigger the exeption.
if(!base.exists()){
base.mkdirs();
FileCopyUtils.copy(new FileInputStream(oldPath), new FileOutputStream(newPath));
}else{
FileCopyUtils.copy(new FileInputStream(oldPath), new FileOutputStream(newPath));
}
image.setJson(newPath);
img.add(image);
}
} catch (FileNotFoundException e) {
e.printStackTrace();
}finally{
deleteTmp();
}
return img;
}
好的家伙问题是，在检查我的方式时，＆＃34; base＆＃34;存在于服务器中，它不是创建的，并且正在启动FileNotFoundException异常。
但奇怪的是，在我的机器上行为是正常的。并且只发生在我的Amazon EC2实例上。
我想知道你是否同意我的逻辑，如果我错过了什么。
最好的问候
