我有两个数据库（第一个和第二个）的Spring启动 . 我有这个工作配置：

@Bean
public DataSourceTransactionManager firstDbTransactionManager(@Qualifier ("primaryDataSource") DataSource datasource) {
    return new DataSourceTransactionManager(datasource);
}

@Bean
public DataSourceTransactionManager secondDbTransactionManager(@Qualifier("secondaryDataSource") DataSource datasource) {
    return new DataSourceTransactionManager(datasource);
}

我有两个db需要@Transactional的方法 . 我一直在做，它工作正常：

@Autowired
private SubscriptionFeeService thisBeanSelfProxy;

@Transactional("firstDbTransactionManager")
public void withdrawalOfMonthlyFee(Project project) throws Exception {
    thisBeanSelfProxy.intermediateMethod(project);
}

@Transactional("secondDbTransactionManager")
public void intermediateMethod(Project project) throws Exception {
    thisBeanSelfProxy.withdrawalOfMonthlyFeeInner(project);
}

public void withdrawalOfMonthlyFeeInner(Project project) throws Exception {
    firstDbRepository.update(project);
    secondDbRepostory.addNewOperationToProjectTable(project.generateOperations());
    throw new RuntimeException(); //i want rollback both db
}

我正在为@Transactional注释创建intermediateMethod，因为它不支持@Transactional（{“firstDbTransactionManager”，“secondDbTransactionManager”}） . 如何通过一个注释打开两个事务？
