The root cause is the following code:

public static InputStream String2Inputstream(String str) throws IOException {        return new ByteArrayInputStream(str.getBytes("UTF-8"));    }

Add the UTF-8 in getBytes. The root cause is that the encoding method on our server is GBK. At this time, when getBytes is obtained, the encoding method on the server is obtained, and an error is reported.

 

Conclusion: encoding is a key concern when string and binary stream conversion are involved anywhere. All encoding methods must be determined, rather than taken from the server, unified management of coding methods is king. At the same time, I can only sigh, but I am used to it ~
