通过 javax.mail 发送多封电子邮件

Question

我正在尝试使用 JAVA Mail 发送多封邮件 -

当我添加一个收件人时 -

message.addRecipient(Message.RecipientType.TO, new InternetAddress(“abc@xyz.com”));

它工作正常，但当我添加多个电子邮件地址时 -

这里是代码

message.addRecipient(Message.RecipientType.TO, new InternetAddress(“abc@xyz.com”));
message.addRecipient(Message.RecipientType.TO, new InternetAddress(“def@xyz.com"));

message.addRecipient(Message.RecipientType.CC, new InternetAddress(“ghi@xyz.com"));
message.addRecipient(Message.RecipientType.CC, new InternetAddress(“jkl@xyz.com"));

message.addRecipient(Message.RecipientType.BCC, new InternetAddress(“mno@xyz.com"));

邮件已发送和接收，但当我查看abc@xyz.com 的电子邮件时，我看不到该电子邮件也已发送到def@xyz.com，反之亦然。我也看不到列表中的 CC。

来自 abc@xyz.com 的邮件详细信息

from:   xyz@xyz.com
to: abc@xyz.com

来自 def@xyz.com 的邮件详细信息

from:   xyz@xyz.com
to: def@xyz.com

来自 ghi@xyz.com 的邮件详细信息

from:   xyz@xyz.com
to: ghi@xyz.com

来自 jkl@xyz.com 的邮件详细信息

from:   xyz@xyz.com
to: jkl@xyz.com

我尝试稍微改变一下逻辑，但结果相同 -

message.addRecipients(Message.RecipientType.TO, InternetAddress.parse(“abc@xyz.com, def@xyz.com"));

message.addRecipient(Message.RecipientType.CC, InternetAddress.parse(“ghi@xyz.com, jkl@xyz.com”));

message.addRecipient(Message.RecipientType.BCC, InternetAddress.parse(“mno@xyz.com"));

我希望看到详细信息 -

from:   xyz@xyz.com
to: abc@xyz.com, def@xyz.com
cc: ghi@xyz.com, jkl@xyz.com

Answer 1

你应该试试：

Address[] toArray = new Address[] {InternetAddress.parse("abc@xyz.com"),
                               InternetAddress.parse("def@xyz.com")};
message.addRecipients(Message.RecipientType.TO, toArray);

Answer 2

为防止任何错误和意外，我建议使用setRecipients(Message.RecipientType type, Address[] addresses) 作为下一个：

message.setRecipients(
    Message.RecipientType.TO, 
    new Address[]{new InternetAddress("abc@xyz.com"), new InternetAddress("def@xyz.com")}
);
