FileNotFoundException（系统找不到指定的路径） [英] FileNotFoundException (The system cannot find the path specified)

问题描述

  java.io.FileNotFoundException：C：\ ... \filename.xml （系统找不到指定的路径）
  

使用此代码：

  FileWriter fileWriter = new FileWriter（new File（path + date + timefilename.xml））; 
 BufferedWriter writer = new BufferedWriter（fileWriter）; 
 writer.write（data）; 
  

路径存在，但需要创建'date'和'time'目录。应用程序对目录拥有完全的权限。

有什么想法？

解决方案

问题是因为我正在创建一个子目录来写文件。所以我现在有 C：\example\ ，并且想把我的文件写入 C：\ example \< date> \ < time> \< files>

您需要调用 File＃mkdirs（）
$ b

  File file = new File（C：/ example / newdir / NEWDIR / FILENAME.EXT）; 
 file.mkdirs（）; 
 // ... 
  




I get this exception:

java.io.FileNotFoundException: C:\...\filename.xml (The system cannot find the path specified)

using this code:

FileWriter fileWriter = new FileWriter(new File(path + date + time "filename.xml"));
BufferedWriter writer = new BufferedWriter(fileWriter);
writer.write("data");

Path exists but directories for 'date' and 'time' need to be created. Application has full permissions on the directory.

Any ideas?

解决方案

The problem is because I'm creating a subdirectory in which to write the files. So I currently have C:\example\ and want to write my files in C:\example\<date>\<time>\<files>

You need to call File#mkdirs() before writing.

File file = new File("C:/example/newdir/newdir/filename.ext");
file.mkdirs();
// ...
