記錄一個格式：發郵件時顯示郵件聯繫人名稱（暱稱）

一直在用javax.mail發郵件，但是我的郵件顯示的都是郵件地址，像其它服務郵箱，京東，淘寶之類的都顯示的是名稱。很奇怪。

百度之，網上沒有類似。

百度之好久，發現有人說是需要用固定的格式填充From屬性。

// 設置收件人，寄件人
String nick = javax.mail.internet.MimeUtility.encodeText("顯示名稱");
messageHelper.setFrom(new InternetAddress(nick + " <[email protected]>"));
messageHelper.setTo(toMail);
messageHelper.setSubject(subject);

這樣即可，前面的名稱就會正常顯示出來。

附發郵件的代碼：

        <dependency>
            <groupId>javax.mail</groupId>
            <artifactId>mail</artifactId>
            <version>1.5.0-b01</version>
        </dependency>

這是以前寫的代碼，源碼已經找不到的，只有jar還在，現反編譯出來，保存下。
