java.io.FileNotFoundException: (访问被拒绝) 当我有文件权限时
java.io.FileNotFoundException: (Access is denied) when i have permission to the file
所以我收到了这个错误:
java.io.FileNotFoundException: C:\Users\censored\Documents\Electrocode Productions\template\resources\images(访问被拒绝)
当我 运行 此代码时:
package com.template;
import java.io.BufferedInputStream;
import java.io.BufferedOutputStream;
import java.io.File;
import java.io.FileOutputStream;
import java.io.IOException;
import java.io.InputStream;
import java.io.OutputStream;
public class Copy {
static File folder = new File(System.getProperty("user.home") + "/Documents/Electrocode Productions/template");
public static void writeSaves() {
File imagesFile = new File(folder + "/resources/images");
if(!imagesFile.exists()) {
try {
InputStream input = (Main.class.getResourceAsStream("/resources/images"));
BufferedInputStream buffedInput = new BufferedInputStream(input);
File fileFolder = new File(folder + "/resources/images");
try {
fileFolder.mkdirs();
} catch(SecurityException e) {
Log.error(e);
}
OutputStream output = new FileOutputStream(fileFolder);
BufferedOutputStream buffedOutput = new BufferedOutputStream(output);
byte[] buffer = new byte[input.available()];
System.out.println(buffer);
int bytesRead;
while((bytesRead = buffedInput.read(buffer)) > 0 ) {
buffedOutput.write(buffer, 0, bytesRead);
}
input.close();
output.close();
} catch(IOException e) {
Log.error(e);
}
}
尽管我很确定我可以像在代码的另一部分中一样访问该文件,但我还是这样做了:
public static void dump() {
if(!folder.exists()) {
try {
folder.mkdirs();
} catch(SecurityException e) {
Log.error(e);
}
}
Path oldFilePath = Paths.get(folder + "/latest.log");
Path newFilePath = Paths.get(folder + "/" + time.getDayOfMonth() + "." + time.getMonth() + "." + time.getYear() + "_" + time.getHour() + "." + time.getMinute() + "." + time.getSecond() + ".log");
if(Config.get("keeplogs").equals("true")) {
try(BufferedWriter writer = Files.newBufferedWriter(newFilePath, StandardOpenOption.CREATE, StandardOpenOption.APPEND, StandardOpenOption.WRITE)) {
@SuppressWarnings("resource")
Scanner scanner = new Scanner(oldFilePath);
while(scanner.hasNextLine()) {
writer.write(scanner.nextLine());
writer.newLine();
}
} catch(IOException e) {
e.printStackTrace();
}
} else if(Config.get("keeplogs").equals("false")) {
} else {
Log.warning("Unknown argument " + Config.get("log") + " in config.properties. Must be true or false");
}
}
我做错了什么?这可能是重复的,但可能不是,因为我已经查看了我在此处 (Whosebug) 上可以找到的所有内容并尝试了所有内容。似乎没有任何效果。
您似乎使用 mkdirs 调用创建了 C:\Users\censored\Documents\Electrocode Productions\template\resources\images
目录。然后你试图像打开文件一样打开它,但显然失败了。
这是回答我问题的代码:
public static void writeSaves(File src, File dest) throws IOException {
if(src.isDirectory()){
//if directory not exists, create it
if(!dest.exists()){
dest.mkdirs();
}
//list all the directory contents
String files[] = src.list();
for (String file : files) {
//construct the src and dest file structure
File srcFile = new File(src, file);
File destFile = new File(dest, file);
//recursive copy
writeSaves(srcFile,destFile);
}
}else{
//if file, then copy it
//Use bytes stream to support all file types
InputStream in = new FileInputStream(src);
OutputStream out = new FileOutputStream(dest);
byte[] buffer = new byte[1024];
int length;
//copy the file content in bytes
while ((length = in.read(buffer)) > 0){
out.write(buffer, 0, length);
}
in.close();
out.close();
}
