Conversion of jMolecules `Identifier` implementations to primitive fails with Spring Data JDBC

[ddnyer]

Issue

When using the JMolecules Spring integration with Spring Data JDBC, persisting an entity with an id implementing Identifier fails randomly (sometimes is works, sometimes not). More exactly, it's the conversion of the Identifier to a primitive to populate the SQL query that fails.

Spring Boot version 3.3.1
JMolecules integration version 0.20.0

Stacktrace

The exception is raised when IdentifierToPrimitivesConverter is asked to convert into a UUID an Identifier containing a String id.

Root cause

The issue is in CustomConversions.

In its constructor, CustomConversions creates a list of converters. From DEFAULT_CONVERTERS, it finds IdentifierToPrimitivesConverter from the JMolecule package which registers two converters, one for Identifier -> UUID and one for Identifier -> String. Both pairs are listed as converters and also saved in writingPairs. The order in which they appear in this list is random because IdentifierToPrimitivesConverter use an HashSet to store the supported primitive types used to build the pairs returned by getConvertibleTypes().

Now when getCustomWriteTarget is called to determine the target type of a class implementing Identifier, we get into trouble. It calls getCustomTarget which will pick the first converter with Identifier as source type and return the associated target type. In this case it will randomly return String or UUID. Obviously when the wrong target type is selected, the conversion of the Identifier later on fails.

Sample project

https://github.com/ddnyer/spring-data-jdbc-jmolecules/tree/main

run docker compose up to have a running db then you can run the unit test, it will fail as the wrong target type is returned for one of the Identifier.

[schauder]

@odrotbohm Isn't that a jMolecules issue, since registering two writing converters for the same source type is asking for trouble?

[odrotbohm]

I'll have a look.

[odrotbohm]

I can't get the Gradle project to import properly into Eclipse (looks like Gradle 8.5 doesn't properly run on Java 22)? Would you mind reducing the project to Maven and not require Docker compose, i.e. rather use an in-memory database?

[odrotbohm]

Nevermind, I could copy the test over into the Spring Data Commons' unit tests and could reproduce the problem there.

[odrotbohm]

I think you're onto something but got derailed slightly. First of all, there's something clearly broken, as the originally posted stack trace shows. As you have correctly identified, the order of the identifier primitive types is undefined and depending on which one gets returned first, the lookup in CustomConversions will find and use the first type registered. If that's UUID, the subsequent conversion step will try to convert the high-level identifier type into a UUID event, although the underlying value is an arbitrary String. That's, of course, wrong and broken.

That said, the test case you provide implements an assumption that the component under test cannot satisfy. CustomConversions only knows about the ConvertiblePairs that have been returned by the GenericConverter implementations, applying an instance of check on the source type. It will and cannot analyze the concrete identifier type for the type of its underlying value, as that is part of the actual conversion hidden inside the converter.

It looks like us being very specific about the supported primitive types in getConvertibleTypes() is the actual culprit here. We need to change that to simply return new ConvertibleType(Identifier.class, Object.class) and defer the actual resolution of whether the converter is to be used to matches(…). That change will cause only a single entry registered for Identifier in CustomConversions which will solve the ambiguity. That said, the custom write target will simply be Object then and the downstream triggering of convert will then make sure that the value underlying the Identifier implementation will be used as is.

I'll create a ticket in jMolecules Integrations as the problem fundamentally needs to be solved there.

[ddnyer]

Thanks for the detailed explanation.

Indeed having a single pair new ConvertibleType((Identifier.class, Object.class) seems like a good approach.
