Cannot run job with LocalDate(Time) job parameters

[winfr34k]

I didn't find any obvious duplicate but maybe I'm also misunderstanding the scopes of the Spring Batch project, so maybe this "bug" is really as designed.

Bug description

If a job is run with LocalDate or LocalDateTime job parameters, the run fails because the execution cannot be persisted.
An exception like "No converter found capable of converting from type [java.time.LocalDate] to type [java.lang.String]" is thrown.

Environment

• Spring Boot 3.0.0
• Spring Batch 5.0.0
• H2 Database 2.1.214
• OpenJDK Runtime Environment Temurin-17.0.5+8 (build 17.0.5+8)
• macOS 13.0.1

Steps to reproduce

1. Prepare JobParameters using the JobParametersBuilder with either LocalDate or LocalDateTime instances.
2. Run any job with the aforementioned job parameters

Expected behavior

Since the builder offers convenience methods, I would expect the job execution to just complete with either of them.

Thank you for raising this issue and for providing a sample.

The problem is that the default conversion service from Spring Framework that Spring Batch uses by default does not support the conversion of String literals to/from LocalDate and LocalDateTime OOTB.

The issue could be fixed by providing a conversion service that augments the default one with converters for LocalDate and LocalDateTime. But since the JobParametersBuilder provides methods to add job parameters with such types, I agree that those converters should be provided by default.

I will plan the fix for v5.0.1.
