You can do like this:

@Configuration
public class H2ServerConfiguration {

  @Value("${db.port}")
  private String h2TcpPort;

  /**
   * TCP connection to connect with SQL clients to the embedded h2 database.
   *
   * @see Server
   * @throws SQLException if something went wrong during startup the server.
   * @return h2 db Server
   */
   @Bean
    public Server server() throws SQLException {
        return Server.createTcpServer("-tcp", "-tcpAllowOthers", "-tcpPort", h2TcpPort).start();
   }

   /**
    * @return FlywayMigrationStrategy the strategy for migration.
    */
    @Bean
    @DependsOn("server")
    public FlywayMigrationStrategy flywayMigrationStrategy() {
        return Flyway::migrate;
    }
}
