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?

The translated name is used as the parameter to the get(String) method of members , and Gson provides no mechanism for this final call to be made case insensitive.
You could read the JSONObject into a java string, and call String. toLowerCase on it and store it back into a JSONObject. This will turn the entire case of the string to lower case, so you will have to account for that elsewhere in your logic.
ExclusionStrategy strategy = new ExclusionStrategy() { @Override public boolean shouldSkipClass(Class<?> clazz) { return false; } @Override public boolean shouldSkipField(FieldAttributes field) { return field. getAnnotation(Exclude. class) !=
3. Deserialize JSON With Extra Unknown Fields to Object. As you can see, Gson will ignore the unknown fields and simply match the fields that it's able to.
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.
