我正在尝试使用Spring-Integration-Mail从电子邮件服务器获取电子邮件，下面是我得到的那种跟踪。
从程序的行为角度来看，我注意到只有在程序的初始运行时才能成功检索消息，之后看起来它没有收到任何新的电子邮件，可能是因为IDLE任务失败了？
无论如何，ArrayIndexOutOfBoundsException对我来说似乎很奇怪。我只能告诉INBOX在此脚本运行时包含6条消息，但是其他文件夹中包含消息。
有什么想法吗？

更新
看起来这可能不得不处理已删除的消息，而不是从INBOX中清除bean。当我从桌面邮件客户端检查INBOX时，它在收件箱中显示6条消息，但是当我通过网络邮件登录邮件时，它显示了6封常用电子邮件，1条用一条线交叉，并注释了它们在说INBOX中有7条消息，其中1条被删除。一旦我从INBOX移动了该电子邮件，以前未处理的新邮件就会被spring-mail-integration检索到。
问题是，有没有办法通过spring-mail-integration设置改变这种行为，例如：忽略已删除但未清除的邮件？
