Spring @Transactional,具有跨多个数据源的事务

>我在DB1中做了更新.

如果DB2中的更新失败,我想回滚DB1和DB2以进行回滚.这可以使用@Transactional完成吗？

这是一个示例代码 –

@Transactional(value="db01TransactionManager")
public void updateDb01() {
    Entity01 entity01 = repository01.findOne(1234);
    entity01.setName("Name");
    repository01.save(entity01);

    //Calling method to update DB02
    updateDb02();
}

@Transactional(value="db02TransactionManager")
public void updateDb02() {
    Entity02 entity02 = repository02.findOne(1234);
    entity02.setName("Name");
    repository02.save(entity02);

    //Added this to force a roll back for testing
    TransactionAspectSupport.currentTransactionStatus().setRollbackOnly();
}

我的问题是,updateDb02中的setRollbackOnly()仅回滚Db01事务.

Spring Boot配置：

    @Bean(name = "chainedTransactionManager")
    public ChainedTransactionManager transactionManager(@Qualifier("primaryDs") PlatformTransactionManager ds1,
                                                    @Qualifier("secondaryDs") PlatformTransactionManager ds2) {
         return new ChainedTransactionManager(ds1, ds2);
    }

然后你可以按如下方式使用它：

@Transactional(value="chainedTransactionManager")
public void updateDb01() {
    Entity01 entity01 = repository01.findOne(1234);
    entity01.setName("Name");
    repository01.save(entity01);

    //Calling method to update DB02
    updateDb02();
}

public void updateDb02() {
    Entity02 entity02 = repository02.findOne(1234);
    entity02.setName("Name");
    repository02.save(entity02);

    //Added this to force a roll back for testing
    TransactionAspectSupport.currentTransactionStatus().setRollbackOnly();
}
