使用Scala Salat（使用mongodb casbah），如何存储和加载二进制数据？

Question

I have a product case class defined in the way Salat expects.

case class Product(@Key("product_id") productId: String, 
                   @Key("png_image_binary") pngImageBinary: ???)

How can I add pngImageBinary so I can store this as a binary object?

Answer 1

For binary data you can use Array[Byte] . It's equivalent of java byte[] , which maps to Binary BSON type. Check java types and BSON types from mongodb documentation.
