郵件未使用Apache Commons Mail發送出去

Question

我正在使用1.3.3版Apache Commons Mail來發送電子郵件。 我試過了

• 更改Apache郵件版本
• 使用telnet smtp.gmail.com 587測試連接性（它可以正常工作，因此與防火牆無關）
• 用不同的端口嘗試
• 設置SSL / TSL並嘗試了其他方法
• 將我的gmail配置為啟用IMAP，POP

但郵件仍未發送出去。

這是我的調試消息，谷歌搜索解決方案，但沒有一個解決我的問題

和我的代碼如下

MultiPartEmail email = new MultiPartEmail();
email.setSmtpPort(587);
email.setHostName("smtp.gmail.com");
email.setAuthentication("xxx@gmail.com", "xxx");
email.setDebug(true);
email.setStartTLSEnabled(true);
email.setFrom(from);
email.setSubject(subject);
email.setMsg(msg);
email.addTo(to);
email.attach(attachment);
email.send();

看來您的類路徑中有一個郵件模擬服務。 從名稱猜測，我猜想此實現不會發送真實郵件。

因此，請嘗試從類路徑中刪除該庫，然后重試。

我使用maven時，可以將模擬依賴項的scope設置為test 。
