Missing Neo4jTransactionManager after migrated from Spring Boot 2.7.3 to 3

[luan-cestari-trustly]

To solve the problem, we had to redefine it:

import org.neo4j.driver.Driver;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.autoconfigure.condition.ConditionalOnMissingBean;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.data.neo4j.core.DatabaseSelectionProvider;
import org.springframework.data.neo4j.core.transaction.Neo4jBookmarkManager;
import org.springframework.data.neo4j.core.transaction.Neo4jTransactionManager;
import org.springframework.data.neo4j.repository.config.Neo4jRepositoryConfigurationExtension;

import java.util.Objects;

@Configuration
@SuppressWarnings("unused")
public class Neo4jTransactionConfiguration {

    @ConditionalOnMissingBean(name = Neo4jRepositoryConfigurationExtension.DEFAULT_TRANSACTION_MANAGER_BEAN_NAME)
    @Bean(name = "transactionManager")
    public Neo4jTransactionManager neo4jTransactionManager(@Autowired Driver driver,
                                                           @Autowired DatabaseSelectionProvider databaseSelectionProvider,
                                                           @Autowired(required = false) Neo4jBookmarkManager neo4jBookmarkManager) {
        return new Neo4jTransactionManager(driver, databaseSelectionProvider,
                                           Objects.requireNonNullElseGet(neo4jBookmarkManager, Neo4jBookmarkManager::create));
    }
}

I opened this Issue to share the problem and help people with a workaround until this got fixed

That should not be the case, really. But we do only consult on the Spring Boot integration, not maintain it our self. However, I am relatively sure that we would have heard from the Spring Boot team if there are issues during testing.

Please raise this issue with Spring Boot: https://github.com/spring-projects/spring-boot, maybe sharing your @Configuration classes.

Thank you!
