Enhanced Testcontainers Support

[mbechto]

We were trying to use the mq-container with Spring Boot 3.x Testcontainers with @ServiceConnection similar to what you can do with a PostgreSQL container:

@TestConfiguration(proxyBeanMethods = false)
public class TestcontainersConfiguration {
  @Bean
  @ServiceConnection
  @RestartScope
  PostgreSQLContainer<?> postgresContainer() {
    return new PostgreSQLContainer<>(DockerImageName.parse("postgres:latest"));
  }
}

Our intention is to avoid unnecessary container restarts between @SpringBootTests as that slows down the testing process significantly therefore @RestartScope. Maybe more importantly @ServiceConnection configures the correct connection properties, since Testcontainers exposes services on a random port (by default) this is crucial. So similar to PostgreSQL, we tried something like this:

@TestConfiguration(proxyBeanMethods = false)
public class TestcontainersConfiguration {
  @Bean
  @ServiceConnection
  @RestartScope
  GenericContainer<?> ibmMqTestContainer() {
    return new GenericContainer<>(DockerImageName.parse("ibm-messaging/mq-container:latest"));
  }
}

Resulting in the following error on startup:

org.springframework.boot.autoconfigure.service.connection.ConnectionDetailsNotFoundException: No ConnectionDetails found for source '@ServiceConnection source for Bean 'ibmMqTestContainer' defined in class path resource [TestcontainersConfiguration.class]'. You may need to add a 'name' to your @ServiceConnection annotation

After some debugging through Spring code, I guess this would require some integration to make it work, e.g. implementing some classes similar to the ActiveMQ Testcontainers integration.

• ibmmq-jms-spring version: 3.3.1
• Java version (including vendor and platform): Temurin-21.0.3+9
• A small code sample that demonstrates the issue.
