java - 在Spring集成电子邮件接收适配器中设置我的Store-Uri时，如何转义@字符

Question

我正在使用 imapIdle 为密码中包含字符“@”的电子邮件帐户配置电子邮件接收 channel 。我注意到代码 store-uri 中断了，因为它根据“@”字符分割字符串。

我读了加里·拉塞尔的评论，他说这个角色需要转义。我尝试通过输入“\@”来转义“@”字符，但这不起作用。 store-uri 字符串仍然在第一个“@”字符处被分割。因此我得到

我尝试用其 unicode 表示形式“U+0040”替换“@”，但这也不起作用

store-uri="imaps://${email.username}:${email.password.contains("@")}@outlook.office365.com"
