Answer 1

不确定，请尝试：

int saveToDb= mo.addMembers( memberName, repImage.getBytes() );

If I understand your question properly, you want to store the binary data in your database. I'd say this is a bad idea in the first place for multiple reasons. A better method would be to reference a relative path that you can then use in your web application or the file system directly. Better yet, just store the reference to the location in Amazon/S3 where you want to save it/use it.

Regardless, to answer your question you would want to use ByteArrayOutputStream .
