I want to parse quantities like "1cm", "5m/s" etc.

Describe the solution you'd like
It would be nice to have the ability to pass custom parser/serializers with the annotation.

Describe alternatives you've considered
Make if possible to parse the given quantities by default.

Additional context

Make it possible to enable the automatic use of system units, but disable it by default.

I'm always frustrated when using Quantity Arrays in PostgreSQL

Describe the solution you'd like

    @Column(name = "elevations", nullable = false)
    private Quantity<Length>[] elevations

Describe alternatives you've considered
Converting the Quantity Array to a double Array.

Additional context

We want to use the Unit classes for the JsonUnit/JpaUnit Annotations.
This should prevent misspelling (at runtime), due to compiler checks.

Aceptance Criteria

• JsonUnit value property type is Class<Unit>
• JsonUnit unit property type is Class<Unit>
• JpaUnit value property type is Class<Unit>
• JpaUnit unit property type is Class<Unit>
• All occurences of the String Unit specification gets replaced by the class definition

I would like to Serialize/Deserialize Quantities as Objects

It has come to my attention, that the JPA Usage description is not good enough.

It was not clear for some users, to use the type descriptor annotation for their entity.
This should be improved.

I'm always frustrated when i have to deal with negative Quantities.
Example: Metre(-12.0) < Metre(11.0)

Describe the solution you'd like
It would be nice to have an absolute value converter.
Metre(-12.0).abs() < Metre(11.0)

Describe alternatives you've considered
Currently i use something like:

Quantity<Length> x = Metre(-12.0)
if ((x < Metre(0.0) && x < Metre(-11.0)) || (x > Metre(0.0) && x > Metre(11.0)) {
    ...
}

For the Kotlin Part of my Code i used this extension function:

fun <T : Quantity<T>> Quantity<T>.abs(): Quantity<T> {
    if (this.value.toDouble() < 0)
        return this * -1.0
    return this
}

Provide Extension Methods for the Time Quantity to convert it to a duration and the other way around.

val duration = Duration.ofSeconds(10)
val quantity = duration.toQuantity()
val result = quantity.toDuration()

Describe the bug
JsonQuantityReader Annotation is broken and not covered by test cases.

To Reproduce

1. use the JsonQuantityReader
2. It will not work

Expected behavior

@Target({METHOD, FIELD})
@Retention(RetentionPolicy.RUNTIME)
public @interface JsonQuantityReader {

Additional context
Add any other context about the problem here.

Describe the bug
The springdoc property does not use the specified quantity shape.
