java.io.IOException:传入ByteArrayInputStream时不是GZIP格式
java.io.IOException:传入ByteArrayInputStream时不是GZIP格式,java,jaxb,gzipinputstream,Java,Jaxb,Gzipinputstream,persistenceService.put看起来像 final ByteArrayOutputStream stream = new ByteArrayOutputStream(); try { jaxbContext.createMarshaller().marshal(proposal, stream); try { stream.close();
persistenceService.put
看起来像
final ByteArrayOutputStream stream = new ByteArrayOutputStream();
try {
jaxbContext.createMarshaller().marshal(proposal, stream);
try {
stream.close();
} catch (IOException e) {
throw new PersistenceException("Failed to close output stream for " + proposal.getUniqueId());
}
// call persistenceService.put to send data to respective PersistenceServiceClass
InputStream inputStream = new ByteArrayInputStream(stream.toByteArray());
persistenceService.put(inputStream, proposal.getUniqueId());
当我运行这段代码时,我看到下面的stacktrace
public void put(@Nonnull final InputStream inputStream, @Nonnull final String uniqueId) throws PersistenceException {
// a.) create xml.zip of inputStream as inputStream
final GZIPInputStream zipInputStream;
try {
zipInputStream = new GZIPInputStream(inputStream);
} catch (IOException e) {
e.printStackTrace();
throw new PersistenceException("Persistence Service could not received input stream to persist for " + uniqueId);
}
// b.) call amazonS3client.putObject() to put data
final PutObjectRequest putObjectRequest = new PutObjectRequest(bucketName, getProposalName(uniqueId), zipInputStream, new ObjectMetadata());
}

您可以将其作为
fileInputStream
传递并测试它您正在将一组非gzip字节传递给gzip解压器。
private static void gzip(File file) {
//logic to extract file
GZIPInputStream in = null;
FileInputStream fin = null;
OutputStream out = null;
int noread = 0;
try {
in = new GZIPInputStream(new FileInputStream(file));
extractedFile = new File("C:\\DATA\\extracted.txt");
out = new FileOutputStream(extractedFile);
byte[] buffer = new byte[65536];
noread = in.read(buffer);
while(noread > 0) {
out.write(buffer, 0, noread);
System.out.println("done");
break;
}
}
