Fix #221 Support alternate radixes for numeric values #5317

tiger9800 · 2025-09-16T01:59:24Z

When writing numeric values as strings, we would like to support alternative to base-10 representations. Let's add it via @JsonFormat annotation. Whenever the shape is STRING and pattern is a number, we serialize/deserialize annotated properties using the specified alternative radix.

I based the change on the 2.x branch. I understand that the latest release is 2.20 and this should is a backwards compatible change, so it should be done against the next minor version (2.21), but I could not find it as one of the remote branches.

Also addressing the comments now @pjfanning, thank you.

I considered explicitly throwing here, but this seemed like a more common way to indicate an error.

2.x is the right target branch indeed (for 2.21.x).

Impressive PR!

One big(ger) question/concern I have is the addition of radix in BaseSettings as discrete config option. I think I'd prefer requiring use of "Config Overrides" with JsonFormat.Value a la:

        mapper.configOverride(Integer.TYPE) // for `int`
            .setFormat(JsonFormat.Value.forShape(JsonFormat.Shape.STRING));
            // but with "Value.forPattern("16")"

but I realize there's the problem of changing radix for ALL integral types.

Perhaps that could be tackled by adding actual radix property for @JsonFormat annotation, and then allowing setting of base radix in ConfigOverrides, merged via ConfigOverride.
Or something along those lines.

I'd just not want to force it through all machinery via BaseSettings.

cowtowncoder · 2025-09-18T01:59:26Z

Fails CI; probably uses some Java 17 language feature (2.x still has Java 8 baseline; 3.x has 17)

tiger9800 · 2025-09-19T19:47:31Z

Just want to preface by saying this is not a final change but more of an outline where I am still using pattern as the field containing radix.

A few comments and questions:

I initially wanted to make ConfigOverrides have a JsonFormat.Value field instead of just radix, but there is a test that checks that ObjectReader is serializable. ObjectReader has a reference to ConfigOverrides through some other configs it refers to directly. As a result, we want to serialize ConfigOverrides as a part of that test and JsonFormat.Value is not serializable because Feature does not implement Serializable.
I refactored ConcreteBeanPropertyBase#findPropertyFormat because it seemed like an appropriate place to use _defaultFormat (that I was going to get from ConfigOverride) as a base format that gets overriden by v1 and v2. Since keeping JsonFormat.Value in ConfigOverride did not work, I just reserved to creating a JsonFormat.Value inside the method from an empty format, and I kept the refractor. To make sure the refactor works as intended, I added a unit test that uses stubs. I did not find a lot of other tests that use mockito, so I am not sure it is something you do in the repo. The problem with using mockito is that it shows a warning described here https://openjdk.org/jeps/451. The solution (described here) is adding a VM flag to test run configuration, and a flag to surefire plugin:

<plugin>
	<groupId>org.apache.maven.plugins</groupId>
	<artifactId>maven-surefire-plugin</artifactId>
	<version>3.5.2</version>
	<configuration>
		<argLine>
			-javaagent:${org.mockito:mockito-core:jar}
			-Xshare:off
		</argLine>
	</configuration>
</plugin>

However, the solution only works with newer mockito jars. The mockito-core-4.11.0.jar databind depends on does not specify Premain class in its MANIFEST.MF. I do not know which version is the first one to specify it, but here is an example of Premain being specified in mockito-core-5.19.0.jar's MANIFEST.MF: Premain-Class: org.mockito.internal.PremainAttach.
I also left a TODO saying this needs to be done once mockito is upgraded.

I think we have 2 options here:

Create another issue to upgrade mockito & add the argument to the surefire plugin
Remove the test

Finally, I was wondering what is the correct process for updating another "internal" project databind depends on to use a newly added construct from there. Specifically for adding radix field to the JsonFormat in the annotations repo, how do we get a new release of the annotations repo and then change the databind's pom to point to that new release?

cowtowncoder · 2025-09-19T23:38:15Z

Quick note on:

JsonFormat.Value is not serializable because Feature does not implement Serializable.

I think it's Features (since Feature is Enum and should be java.io.Serializable).
But either way, could you please file an issue on jackson-annotations as we definitely do want all Value objects to be Serializable.
(change to go in 2.21 but good to solve now).

tiger9800 · 2025-09-20T02:21:13Z

Will file an issue and try to address it!

Please let me know what you think about the other questions/concerns once you get the chance.

tiger9800 · 2025-09-26T00:48:54Z

FasterXML/jackson-annotations#316 - made the pull request. Would it make sense to make the change to annotations and go with the initial approach that failed?

cowtowncoder · 2025-10-31T03:16:33Z

Fudge! Was not supposed to merge; need to revert ASAP

cowtowncoder · 2025-10-31T03:48:09Z

I do not know how, but somehow I managed to merge this -- not via UI. So had to revert via #5373.

Not sure how to re-create PR... sorry. I hate git sometimes. Today is such a day. :-(

tiger9800 · 2025-11-03T19:26:04Z

I can just try and get it from my local branch. Should I create a new PR?

JooHyukKim · 2025-11-04T00:50:37Z

New PR sounds good @tiger9800

tiger9800 · 2025-11-12T17:40:29Z

I think the changes are still in. Though the change is incomplete, and I will finish it in with a new PR that starts using radix property of @JsonFormat annotation. We just need to merge FasterXML/jackson-annotations#321 first. I would appreciate if you could help with that @JooHyukKim.

pjfanning · 2025-11-12T18:03:59Z

Just my opinion but I would prefer if this was removed from 2.x and only a 3.x target considered.

tiger9800 · 2025-11-12T18:08:39Z

Do you mean the new pull request or should we revert the changes from this one in 2.x?

cowtowncoder · 2025-11-12T18:08:53Z

Agree wrt this targeting 3.1.
Note tho that annotation support needs to go in annotations 2.21 (PR is pointing to 2.x which is just fine).

cowtowncoder · 2025-11-12T18:09:32Z

Do you mean the new pull request or should we revert the changes from this one in 2.x?

New PR with changes targeting 3.x. Changes were reverted from 2.x already.

tiger9800 · 2025-11-12T18:12:35Z

I see it in my 2.x local branch after pulling, but I guess there is a different 2.x branch somewhere. I will make the new PR targeting 3.x once the annotation change is merged.

cowtowncoder · 2025-11-12T19:36:53Z

@tiger9800 Just merged annotations changes -- should be available via 2.21-SNAPSHOT

cowtowncoder · 2025-11-13T18:20:58Z

I see it in my 2.x local branch after pulling, but I guess there is a different 2.x branch somewhere.

Main Github repo has 2.x branch too. The fact your remote repo (fork) used same name somehow contributed to accidental merge I did. Fwtw.

tiger9800 · 2025-11-18T19:42:10Z

I pulled the 3.x branch, but it does not look like radix made it to JsonFormat for some reason. Anything special I need to do?

pjfanning · 2025-11-18T19:50:45Z

Jackson-annotations remains as a 2.x only release. Ignore any 3.x snapshots. Use com.fasterxml.jackson.core jackson-annotations 2.21-SNAPSHOT.
(it will be pulled by jackson-databind from 3.x branch (3.1.0-SNAPSHOT))

pjfanning · 2025-11-18T19:53:13Z

https://github.com/FasterXML/jackson-annotations/blob/54cc2e40b317dfcf8984da22c9cae36cc897b36e/release-notes/VERSION-2.x#L23

Looks like you need the 2.21-SNAPSHOT

tiger9800 · 2025-11-18T20:10:12Z

When I look at the version pulled in from jackson bom, I see <jackson.version.annotations>2.21-SNAPSHOT</jackson.version.annotations>.

However, I see that it says that 2.21 is not released yet in the release notes hence databind cannot use it.

pjfanning · 2025-11-18T21:16:23Z

Your PR can use jackson-annotations 2.21-SNAPSHOT - we will ensure that the jars are released in the right order.

If you create a branch based on jackson-databind 3.x branch, that build should already depend on jackson-annotations 2.21-SNAPSHOT.

cowtowncoder · 2025-11-18T22:38:06Z

@tiger9800 Things "should just work" when starting branch from 3.x -- it has version 3.1.0-SNAPSHOT and depends on matching SNAPSHOT versions of its dependencies. At worst you may need to use -U flag for Maven to force update (reload) SNAPSHOT dependencies.

@tiger9800 I am not sure how you get the sources, but have a look at jar they come from, it is likely an older version: needs to be "2.21-SNAPSHOT".

Jackson-annotations, branch 2.x has:

    Add radix property to JsonFormat (#320) (#321)

and CI-built and published to Sonatype snapshot repo.

So something in your system is stale. It could be jackson-base or jackson-bom bringing in, say, version 2.20.

The name of the jar says it's 2.21: jackson-annotations-2.21-20250909.010129-3-sources.jar

cowtowncoder · 2025-11-20T22:58:15Z

From September…. Way old 😀 ``` 20250909.010129-3-sources.jar ^^ ``` so you need to make sure you get later/-est snapshot either built locally, or from Sonatype snapshot repo (as defined on `pom.xml` of project you are building). Or refresh IDE etc.

I thought maybe it was my change but after dropping my commit I still see the same issue with other tests. Any chance you know what is happening?

JooHyukKim · 2025-11-29T08:02:55Z

@tiger9800 test actions seem to be passing, so try clearing library cache

tiger9800 · 2025-11-29T18:37:50Z

@JooHyukKim I think the actions use maven and mvn test work locally for me too. However, I cannot debug with maven, so I tried using Intellij and saw the error above.
