如何将 zip 文件转换为字节？
byte[] ba; InputStream is = new ByteArrayInputStream(ba); InputStream zis = new ZipInputStream(is);
byte[] ba; InputStream is = new ByteArrayInputStream(ba); InputStream zis = new ZipInputStream(is);

You can read a file from disk into a byte[]using
您可以将文件从磁盘读入byte[]using
byte[] ba = java.nio.file.Files.readAllBytes(filePath);
This is available from Java 7.
这在 Java 7 中可用。

The basic principle is to feed the InputStreaminto the OutputStream, for example...
其基本原理是喂InputStream到OutputStream，例如...
byte bytes[] = null;
try (FileInputStream fis = new FileInputStream(new File("..."))) {
try (ByteArrayOutputStream baos = new ByteArrayOutputStream()) {
byte[] buffer = new byte[1024];
int read = -1;
while ((read = fis.read(buffer)) != -1) {
baos.write(buffer, 0, read);
}
bytes = baos.toByteArray();
}
} catch (IOException exp) {
exp.printStackTrace();
}
