public static class JsonText.ByteArrayToStringOrJsonSerializer extends com.fasterxml.jackson.databind.ser.std.StdSerializer<byte[]>
Custom serializer for byte arrays.

This serializer attempts to convert a byte array to a string and parse it as JSON. If the string is valid JSON, it serializes the byte array as JSON. If the string is not valid JSON, it serializes the byte array as a plain string.

To use this serializer, annotate the relevant field or class with @JsonSerialize(using = ByteArrayToStringOrJsonSerializer.class).

Example usage: 

 
 public class Example {

     @JsonSerialize(using = ByteArrayToStringOrJsonSerializer.class)
     private byte[] byteArray;

     // getters and setters
 }

In this example, the byteArray field will be serialized using the ByteArrayToStringOrJsonSerializer, which will serialize the value as JSON if it's valid JSON, or as a plain string otherwise.
