[JSONRPC-18] Add support for invocation of RPC method with object argument

Fri, 23 Mar 2018 19:59:11 +0000

Messagelib currently support only scalar method argument types.

It is possible to add support for them.

Consider this POJO

public class SomePojo {
    private int field1;
    private String field2;
    // + getters/setters
}

And this RPC method

public interface SomeRpc {
    Result callMe(SomePojo input);
}

This RPC method can be invoked like this:

{"jsonrpc":"2.0","id":2,"method":"callMe","params":{"field1":10,"field2":"ABC"}}

Also it is possible to exploit GSON feature to add explicit mapping of parameter name to java field name. Let's say you have parameters named "field-1" and "field-2"

{"jsonrpc":"2.0","id":2,"method":"callMe","params":{"field-1":10,"field-2":"ABC"}}

Now you can specify json field name using annotation `SerializedName`:

import com.google.gson.annotations.SerializedName;
public class SomePojo {
    @SerializedName("field-1")    
    private int field1;
    
    @SerializedName("field-2")
    private String field2;    
    // + getters/setters
}
