JAVA: Converting Struct protobuf type to Map<String, Object> in java

[Kush Trivedi]

Hi,

I have been working on a java-grpc side-project & I have been stuck at a point. I have an variable of Struct(protobuf) type & now I want it to convert to Map<String, Object> since Jackson is unable to serialise a Struct(protobuf) type object.

I tried to search the web but it was all in vain, can anyone help how can I approach solving this problem?

Regards,

Kush

I'm not aware of such a util. Most of the consumers of Struct use Struct directly. I think you'd need to write a converter. Seems like a simple recursive converter could be written in, say, ~30 lines of code. Value is very simple, so it'd mainly be a switch on the kind oneof.
