问题描述
三天我试图弄清楚如何使用相对文件路径读取文件。在日食这编译和工作很好,但是当我出口的应用程序。它说,它无法找到该文件。这里是截图和我工作的代码。这个代码可以工作,但只有在eclipse中,它编译和完成工作。但是,当我出口作为可运行jar文件,我得到一个错误,它无法找到licenca.txt
BufferedReader in = new BufferedReader(new FileReader(new File(licenca.txt)。getPath()));
String str; ((str = in.readLine())!= null){
taLicenca.append(str +\\\
);
$ p
$ b $ p这里是我的项目文件的截图
我曾尝试使用扫描仪功能,仍然是相同的结果,它在日食,但不在出口工作。这里是错误信息:
解决方案如果你把这个文件放到类路径中,它会起作用的。
更改您的代码:
InputStream is = this。 。的getClass()getClassLoader()的getResourceAsStream( licenca.txt);
BufferedReader in = new BufferedReader(new InputStreamReader(is));
String str; ((str = in.readLine())!= null){
taLicenca.append(str +\\\
);
试试看。
Three days i was trying to figure out how to read file using relative file path. In eclipse this compiles and works great, but when i export app. It says that it can't find the file. here is the screenshot and code i work on.
This code works, but only in eclipse, it compiles and does job perfectly. But when i export it as as runnable jar file i get an error, that it cannot locate licenca.txt
BufferedReader in = new BufferedReader(new FileReader(new File("licenca.txt").getPath()));
String str;
while ((str = in.readLine()) != null) {
taLicenca.append(str + "\n");
}
here is the screenshot of my project files

i have tried use of scanner function, still the same result, it works in eclipse, but doesn't work on export. Here is the error message:

解决方案 I'll bet it'll work if you put that file into the classpath.
Change your code like this:
InputStream is = this.getClass().getClassLoader().getResourceAsStream("licenca.txt");
BufferedReader in = new BufferedReader(new InputStreamReader(is));
String str;
while ((str = in.readLine()) != null) {
taLicenca.append(str + "\n");
}
Try it and see.
