我有一个文件,我的 Java 应用程序将其作为输入,我一次读取 6 个字节。当我从文件系统中读取它时,一切正常。如果我将所有内容构建到一个 jar 中,则第一个 4868 读取工作正常,但之后它开始以错误的顺序返回字节数组,并且最后还读取了更多数据。
这是我的代码的简化版本,它重现了该问题:
InputStream inputStream = this.getClass().getResourceAsStream(filePath);
byte[] byteArray = new byte[6];
int counter = 0;
while ((inputStream.read(byteArray) != -1))
{
counter++;
System.out.println("Read #" + counter +": " + Arrays.toString(byteArray));
}
System.out.println("Done.");
这是我在读取文件系统时得到的 [缩写] 输出:
...
Read #4867: [5, 0, 57, 7, 113, -26]
Read #4868: [2, 0, 62, 7, 114, -26]
Read #4869: [2, 0, 68, 7, 115, -26]
Read #4870: [3, 0, 75, 7, 116, -26]
Read #4871: [2, 0, 83, 7, 117, -26]
...
Read #219687: [1, 0, 4, -8, 67, 33]
Read #219688: [1, 0, 2, -8, 68, 33]
Read #219689: [5, 0, 1, -8, 67, 33]
Done.
这是我从一个罐子里读到的:
...
Read #4867: [5, 0, 57, 7, 113, -26]
Read #4868: [2, 0, 62, 7, 113, -26] //everything is fine up to this point
Read #4869: [7, 114, -26, 2, 0, 68]
Read #4870: [7, 115, -26, 3, 0, 75]
Read #4871: [7, 116, -26, 2, 0, 83]
...
Read #219687: [95, 33, 1, 0, 78, -8]
Read #219688: [94, 33, 1, 0, 76, -8]
Read #219689: [95, 33, 1, 0, 74, -8]
...
Read #219723: [67, 33, 1, 0, 2, -8]
Read #219724: [68, 33, 5, 0, 1, -8]
Read #219725: [67, 33, 5, 0, 1, -8]
Done.
我解压 jar 并确认正在读取的文件是相同的,那么什么会导致阅读器返回不同的结果呢?
