Spring cloud GCP data spanner fails with spring boot 3.4.X

[vvahtola]

When trying to start a spring boot 3.4.X -based app that uses spring cloud gap data spanner to configure spanner functionality, the following error prevents the app from starting:

---

An attempt was made to call a method that does not exist. The attempt was made from the following location:
com.google.cloud.spring.autoconfigure.spanner.SpannerTransactionManagerAutoConfiguration$DatabaseClientTransactionManagerConfiguration.spannerTransactionManager(SpannerTransactionManagerAutoConfiguration.java:68)

The following method did not exist:

'void org.springframework.boot.autoconfigure.transaction.TransactionManagerCustomizers.customize(org.springframework.transaction.PlatformTransactionManager)'

The calling method's class, com.google.cloud.spring.autoconfigure.spanner.SpannerTransactionManagerAutoConfiguration$DatabaseClientTransactionManagerConfiguration, was loaded from the following location:

jar:file:/Users/.../.m2/repository/com/google/cloud/spring-cloud-gcp-autoconfigure/5.10.0/spring-cloud-gcp-autoconfigure-5.10.0.jar!/com/google/cloud/spring/autoconfigure/spanner/SpannerTransactionManagerAutoConfiguration$DatabaseClientTransactionManagerConfiguration.class

The called method's class, org.springframework.boot.autoconfigure.transaction.TransactionManagerCustomizers, is available from the following locations:

jar:file:/Users/.../.m2/repository/org/springframework/boot/spring-boot-autoconfigure/3.4.1/spring-boot-autoconfigure-3.4.1.jar!/org/springframework/boot/autoconfigure/transaction/TransactionManagerCustomizers.class

The called method's class hierarchy was loaded from the following locations:

org.springframework.boot.autoconfigure.transaction.TransactionManagerCustomizers: file:/Users/.../.m2/repository/org/springframework/boot/spring-boot-autoconfigure/3.4.1/spring-boot-autoconfigure-3.4.1.jar

Action:

Correct the classpath of your application so that it contains compatible versions of the classes com.google.cloud.spring.autoconfigure.spanner.SpannerTransactionManagerAutoConfiguration$DatabaseClientTransactionManagerConfiguration and org.springframework.boot.autoconfigure.transaction.TransactionManagerCustomizers

---

Downgrading the app to use spring boot 3.3.7 allows the app to run.

The current released versions are not compatible with spring boot 3.4.x yet.
We are working on a new version in #3411, and will be released soon after the release of Spring Boot 3.4.2.

I would recommend waiting for this release and report back to us if this is still an issue. Otherwise, you can also test out from the feature branch.
