Method Detail

gsonBuilderWithBase64EncodedByteArrays

public static GsonBuilder gsonBuilderWithBase64EncodedByteArrays()

Obtain a GsonBuilder which Base64-encodes byte[] properties when reading and writing JSON.

A custom com.google.gson.TypeAdapter will be registered via GsonBuilder#registerTypeHierarchyAdapter(Class, Object) which serializes a byte[] property to and from a Base64-encoded String instead of a JSON array.

NOTE: Use of this option requires the presence of the Apache Commons Codec library on the classpath when running on Java 6 or 7. On Java 8, the standard Base64 facility is used instead.
