@Override
public JsonElement serialize(LogThrowable throwable, Type typeOfSrc, JsonSerializationContext context) {
JsonObject json = new JsonObject();
json.addProperty("className", throwable.getClassName());
json.addProperty("message", throwable.getMessage());
json.add("stackTraces", context.serialize(throwable.getStackTraces(), StackTraceElement[].class));
LogThrowable cause = throwable.getCause();
if (cause != null) {
json.add("cause", context.serialize(cause, LogThrowable.class));
}
return json;
