Suggest adding custom features to Gson for LocalDateTime and LocalDate #18
Description
Since use com.google.gson.Gson to parse the json of Etherscan's api response.
However the error will appear:
io.api.etherscan.error.ParseException: Unable to make field private final java.time.LocalDate java.time.LocalDateTime.date accessible: module java.base does not "opens java.time" to unnamed module @38d8f54a
The reason is at:
io.api.etherscan.core.impl.BasicProvider
Line 47:
this.gson = new Gson();
I change the below code to fix this issuse:
this.gson = new GsonBuilder()
.registerTypeAdapter(LocalDateTime.class, (JsonSerializer<LocalDateTime>) (src, typeOfSrc, context) -> new JsonPrimitive(src.format(DateTimeFormatter.ofPattern("yyyy-MM-dd HH:mm:ss"))))
.registerTypeAdapter(LocalDate.class, (JsonSerializer<LocalDate>) (src, typeOfSrc, context) -> new JsonPrimitive(src.format(DateTimeFormatter.ofPattern("yyyy-MM-dd"))))
.registerTypeAdapter(LocalDateTime.class, (JsonDeserializer<LocalDateTime>) (json, type, jsonDeserializationContext) -> {
String datetime = json.getAsJsonPrimitive().getAsString();
return LocalDateTime.parse(datetime, DateTimeFormatter.ofPattern("yyyy-MM-dd HH:mm:ss"));
}).registerTypeAdapter(LocalDate.class, (JsonDeserializer<LocalDate>) (json, type, jsonDeserializationContext) -> {
String datetime = json.getAsJsonPrimitive().getAsString();
return LocalDate.parse(datetime, DateTimeFormatter.ofPattern("yyyy-MM-dd"));
}).create();
Maybe the best way is either update the source code or supply a custom features.
