带有 Javax 单元的 Quarkus Panache Mongo 实体

Question

我正在编写一个应用程序，它需要使用不同的测量单位来跟踪各种数量的东西。

我想借助javax.measure 和 tec.units 的参考实现来存储这些测量数据

这里的问题是 Panache/Mongo 似乎不知道如何处理数据类型。 例如：

...
import javax.measure.Unit;
...


@EqualsAndHashCode(callSuper = true)
@Data
@MongoEntity(collection = "inventoryItem")
public class InventoryItem extends PanacheMongoEntity {
    ...
    private Unit capMeasurement;

}

将产生以下我尝试持久化 class 的结果：

Cannot use 'TransformedUnit' with the PojoCodec.: java.lang.ClassCastException: class sun.reflect.generics.reflectiveObjects.ParameterizedTypeImpl cannot be cast to class java.lang.Class (sun.reflect.generics.reflectiveObjects.ParameterizedTypeImpl and java.lang.Class are in module java.base of loader 'bootstrap')

我对（生成的龙目岛） equals() / toString()中的对象也有以下错误：

我想知道这里的核心问题是否相同。

我正在考虑解决此问题的一种方法是将字符串值简单地映射到库中的常量并存储该字符串值，但不确定是否有人知道可能更兼容的库/实现。

作为参考，使用以下依赖项：

    compile 'javax.measure:unit-api:2.1.2'
    compile 'tec.units:unit-ri:1.0.3'

我对 javax.measure 一无所知，但是带有 Panache 的 MongoDB 使用 MongoDB 的 POJO 编解码器将您的 object 转换为 BSON 文档。

如果此编解码器无法将 object 转换为 BSON 文档，则需要为导致问题的类型创建专用编解码器。 这个编解码器将被 Quarkus 自动拾取并注册到 MongoDB 客户端。

您可以阅读以下有关 Quarkus 中 MongoDB 编解码器用法的部分： https://quarkus.io/guides/mongodb#simplifying-mongodb-client-usage-using-bson-codec
