带有 Javax 单元的 Quarkus Panache Mongo 实体

[英]Quarkus Panache Mongo entity with Javax Units

问题描述

I'm writing an application that needs to keep track of various amounts of stuff with differing units of measurement.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。

I would like to store this measurement data with the help of javax.measure, and a reference implementation from tec.units我想借助javax.measure 和 tec.units 的参考实现来存储这些测量数据

The problem here is that Panache/ Mongo does not seem to know how to process the datatypes.这里的问题是 Panache/Mongo 似乎不知道如何处理数据类型。 For instance:例如：

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


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

}

Will yield the following of I attempt to persist the class: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')

I also have trouble with the objects in the (lombok generated) equals() / toString() for the following error:我对（生成的龙目岛） equals() / toString()中的对象也有以下错误：

I am wondering if the core issue is the same here.我想知道这里的核心问题是否相同。

One way I was thinking about getting around this was by simply mapping a string value to the constants in the library and storing that string value, but was unsure if anyone knew of a perhaps more compatible library/implementation.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。

For reference, using the following dependencies: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'

I don't know anything about javax.measure but MongoDB with Panache uses the POJO Codec of MongoDB to transform your object to a BSON document.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。

If this codec is not able to transform your object to a BSON document, you need to create a dedicated codec for the type that causes the issue.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。 This codec will be automatically picked up by Quarkus and registered to the MongoDB client.这个编解码器将被 Quarkus 自动拾取并注册到 MongoDB 客户端。

You can read the following section about MongoDB codec usage in Quarkus: https://quarkus.io/guides/mongodb#simplifying-mongodb-client-usage-using-bson-codec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
