因为我在该对象上使用了 bigdecimal 类型而没有添加注释 @Field(type = FieldType.Double)

有没有办法为 bigdecimal 配置默认 FieldType.Double ？或者我们需要为每个 bigdecimal 添加字段注释

问题出在我的解散杰克逊..通过添加这个来修复

公共类 BigDecimalMoneyDeserializer 扩展 JsonDeserializer {

@Override
public BigDecimal deserialize(JsonParser jp, DeserializationContext ctxt) throws IOException, JsonProcessingException {
    return jp.getDecimalValue().setScale(2, BigDecimal.ROUND_HALF_UP);
}

}
