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

有没有办法为bigdecimal配置默认FieldType.Double？或者我们需要在每个bigdecimal中添加字段表示

问题出在我的去世俗化杰克逊..通过添加以下内容进行修复

公共类BigDecimalMoneyDeserializer扩展了JsonDeserializer {

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

}
