Quarkus Panache Mongo 实体与 Javax 单元

标签： java mongodb quarkus quarkus-panache

我正在编写一个应用程序，需要跟踪具有不同测量单位的各种数量的东西。

我想在 javax.measure, and a reference implementation from tec.units

的帮助下存储此测量数据

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类的结果：

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')

我在处理（lombok 生成的）equals()/toString() 中的对象时也遇到了以下错误：

我想知道这里的核心问题是否相同。

我正在考虑解决这个问题的一种方法是简单地将字符串值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'

1 个答案:

答案 0 :(得分：0)

我对 javax.measure 一无所知，但 MongoDB with Panache 使用 MongoDB 的 POJO 编解码器将您的对象转换为 BSON 文档。

如果此编解码器无法将您的对象转换为 BSON 文档，则您需要为导致问题的类型创建专用的编解码器。这个编解码器会被 Quarkus 自动选取并注册到 MongoDB 客户端。

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