Question

Apache Camel Mail Component是否支持重复使用TCP连接发送批量电子邮件？

如果没有，编写自定义org.apache.camel.component.mail.JavaMailSender是否可行/可推荐？

Answer 1

我认为使用标准的camel邮件组件是不可能的，并且实现JavaMailSender也不会为你做到这一点。

如果您查看org.apache.camel.component.mail.MailProducer（2.13.0）：

只有1个消息或交换对象发送/处理。因此，使用您需要的功能实现自己的“BulkMailComponent”可以为您提供解决方案。
