Question

In prototyping communication between .NET desktop app and Java server, using REST with JSON posts, I am running into a case-sensitivity issue. The .NET objects have there properties in Pascal Casing (which is conventional for .NET), e.g.: Symbol, EntryValue (etc), while the Java representation of same object uses camel casing, e.g. symbol, entryValue.

The server receives json value as:

{"EntrySize":100,"Symbol":"AMZN"}

But Gson doesn’t deserialize in case-insensitive manner. Is there any way to get Gson to do this?

Answer 1

Use FieldNamingPolicy on a GsonBuilder, to get your Gson object. Yours seems to match UPPER_CAMEL_CASE.

Gson gson = new GsonBuilder()
        .setFieldNamingPolicy(FieldNamingPolicy.UPPER_CAMEL_CASE)
        .create();

For any exceptions, annotate your class field with a @SerializedName annotation.
