如何在java中强制JSON日期不接受整数

Answer 1

首先创建一个类自定义localDate反序列化器

公共类LocalDateDserializer扩展StdDeserializer{

private final SimpleDateFormat formatter = new SimpleDateFormat("yyyy-MM-dd");

public LocalDateDserializer() {
    this(null);
}

public LocalDateDserializer(final Class<?> vc) {
    super(vc);
}

@Override
public LocalDate deserialize(final JsonParser jsonparser, final DeserializationContext context)
        throws IOException, JsonProcessingException {
    final String date = jsonparser.getText();
    try {
        return formatter.parse(date).toInstant().atZone(ZoneId.systemDefault()).toLocalDate();
    } catch (final ParseException e) {
        throw new RuntimeException(e);
    }
}

}
