Conversion between bytes and objects in Java

Recently the company has used Message Queuing, and as we know is the binary form between message queues, share the conversion between bytes and objects in Java.

The main use of the Bytearrayoutputstream and objectoutputstream two output streams, as well as Bytearrayinputstream and objectinputstream two input streams. Don't say much nonsense, go directly to the code!
