convert json to any protocol buffer java

[stephanie mulder]

Hi,

I want to convert any protocol buffer to json.

My protocol buffer looks as below.

```

syntax = "proto3";

message A {

   int32 id = 1;

}

message B {

   int32 id = 2;

}

message C {

   int32 id = 3;

}

```

I am converting each of them as follows using JsonFormat:

```

String jsonString;

A.Builder Abuilder = A.newBuilder();

JsonFormat.parser().ignoringUnknownFields().merge(jsonString, builder);

A a = Abuilder.build();

Similarly for B

B.Builder Bbuilder = B.newBuilder();

JsonFormat.parser().ignoringUnknownFields().merge(jsonString, builder);

B b = Bbuilder.build()

```

I wanted to know if I can write a generic method using template or java generics or using ```com.google.protobuf.Message``` so that I don't have to write the same method for each of my protocol buffer.

Thanks,

Stephanie
