我已经使用ChainedTransactionManager解决了这个问题-

I've solved this problem using ChainedTransactionManager - http://docs.spring.io/spring-data/commons/docs/1.6.2.RELEASE/api/org/springframework/data/transaction/ChainedTransactionManager.html

Spring Boot配置:

Spring Boot Configuration:

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

然后您可以按以下方式使用它:

And then you can use it as follows:

@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();
}
