我使用spring-boot和spring集成来接收电子邮件并将附件保存到文件中。
我使用了PseudoTransactionManager，因为我想在电子邮件没有附件的情况下引发异常和角色（在角色中我将电子邮件移动到失败文件夹并在提交时将其移动到成功文件夹）。
@Bean(name="emailTransactionManager")
public PseudoTransactionManager emailTransactionManager() {
return new PseudoTransactionManager();
}
@Bean(name="transactionManager")
@Primary
public PlatformTransactionManager transactionManager() {
return new JpaTransactionManager();
}
每件事情都很好，除非我回来时我得到了以下错误。

我不知道它是一个spring-boot还是集成但是日志记录适配器订阅了errorChannel并且它不能自动装入transactionManager我试图用@Primary注释transactionManager但是它没有工作< / p>

我发现问题，在拆分器上，该方法使用@Transactional注释，因此它使用默认的transactionManager。
要确认我使用@Transactional(transactionManager="emailTranasactionmanager")进行了尝试，它确实有效。在我的情况下，我刚删除了@Transaction，因为我只需要一次交易。
