Extract out later this empty file is missing, excuse me each big shrimp: what is this? How to solve?

PS:
Some compression on the software that is the case, as shown in figure:


Attach a snippet:

 
Try {
ZipOutputStream out=new ZipOutputStream (new FileOutputStream (strZipPath)); 
//need to download multiple files at the same time 
//traverse folders, assembly file directory 
Set Keys.=folderMap keySet (); 
For (Integer key: keys) {
HashMap ValueItem=folderMap. Get (key); 
//absolute path to the file name (format:/LJZSG/fastdfs/file/data/00/06/wKgD91vHCPuAJdNzAAEn6ED7yKg207. JPG) 
String urlPath=valueItem. Get (" url "); 
//the full path to the file name (format: test \ \ 2 2. JPG) 
String fullPathName=valueItem. Get (" fullPathName "); 

If (FileType. FILE. GetValue (). The toString (). The equals (valueItem. Get (" type "))) {//type of the FILE, then download 
if (null !=urlPath & amp; & !" ". The equals (urlPath) 
& & Null!=fullPathName & amp; & !" ". The equals (fullPathName)) {
//Java. IO. File f=new Java. IO. The File (absolutePathName); 
//a FileInputStream fis=new FileInputStream (f); 
BufferedInputStream in=dfsClient. DownLoad (urlPath); 
Out. PutNextEntry (new ZipEntry (fullPathName)); 
//set up a character encoding in the compressed file, or it will become garbled 
Out. SetEncoding (" GBK "); 
Int len. 
//read the content of the need to download the file, packaged into zip file 
While ((len=in. Read (buffer)) & gt; 0 {
Out. Write (buffer, 0, len); 
} 
Out. CloseEntry (); 
in.close(); 
} 

} else if (FileType. DEMAND_FOLDER. GetValue (), toString (). The equals (valueItem. Get (" type ")) 
| | FileType. DEMAND_REFERENCE_SUB_FOLDER. GetValue (). The toString (). The equals (valueItem. Get (" type ")) 
| | FileType. INTERPOSE_REFERENCE_SUB_FOLDER. GetValue (). The toString (). The equals (valueItem. Get (" type ")) 
| | FileType. VALIDATE_REFERENCE_SUB_FOLDER. GetValue (). The toString (). The equals (valueItem. Get (" type ")) 
| | FileType. OTHER_FOLDER. GetValue (). The toString (). The equals (valueItem. Get (" type "))) {//type to folder, then the packaging empty folder 
if (null !=fullPathName & amp; & !" ". The equals (fullPathName)) {
Out. PutNextEntry (new ZipEntry (fullPathName + Java. IO. File. The separator)); 
//set up a character encoding in the compressed file, or it will become garbled 
Out. SetEncoding (" GBK "); 
Out. CloseEntry (); 
} 
} 
} 
Out. The close (); 
Logger. The info (download "start"); 
Logger. The info (" fileNameNoSufix="+ FileUtil. GetFileNameNoEx (filename)); 
DownloadFile (request, response, strZipPath, FileUtil getFileNameNoEx (filename) + ". Zip "); 
Logger. The info (" download end "); 
Java. IO. File temp=new Java IO. The File (strZipPath); 
{if (temp. The exists ()) 
Temp. The delete (); 
Logger. The info (" delete the zip file. "); 
} 
} the catch (Exception e) {
Logger. Error (ReturnCode ERR_DOWNLOAD_FAILED + "", e); 
}

Meet the same problem not clear why

CodePudding user response:

Found two problems:
1. You should use UTF8 encoding is better, this as file and directory name, are less likely to produce noise,
2. FolderMap. KeySet () returns a collection of the inside of the content is unordered, how do you ensure storage directory first, and then store files in the directory? Try out the effect of row a sequence,
