Question

我想用自己的值替换application-dev.hml属性文件中的邮件设置值。我这样做：

$date = array ('today', 'yesterday', 'in last week', 'in last month');
foreach( $date as $item ) {
    $sum = $sums[$item];
    $color = '';

    if ($sum < 0) {
        $color = 'red';
    } elseif ($sum > 0) {
        $color = 'green';
    } else {
        $color = 'black';
    }

    $html .= '<span style="color:'.$color.';">'.$sums[$item].'</span>';
} echo $html;

但是当我收到邮箱中的邮件时。它仍然来自属性文件中设置的地址（userLogin@gmail.com）：

Properties properties = new Properties();
properties.put("mail.smtp.host", "ssl0.ovh.net");
properties.put("mail.smtp.user", "myOwnLogin@myApp.fr");
properties.put("mail.smtp.password", "xxx");
properties.put("mail.smtp.port", "25");
properties.put("mail.smtp.auth", "true");
properties.put("mail.smtp.starttls.enable", "true");
javaMailSender.setJavaMailProperties(properties);
MimeMessage mimeMessage = javaMailSender.createMimeMessage();
MimeMessageHelper message = new MimeMessageHelper(mimeMessage, isMultipart, CharEncoding.UTF_8);
message.setFrom("myOwnLogin@myApp.fr");

如何动态更改Java代码中的邮件设置？

感谢。

更新：

mail:
    host: smtp.gmail.com
    port: 587
    username: userLogin@gmail.com
    password: xxxxxx
    protocol: smtp
    properties.mail.smtp:
        auth: true
        starttls.enable: true

很奇怪，我需要使用任何工作值重置javaMailSender属性（这里的值与属性文件中的值相同），然后我可以设置＆＃34; From＆＃34;值。这很难看，但它确实有效。

Answer 1

试试这个

    mimeMessage.setFrom(new InternetAddress(userName));
    mimeMessage.saveChanges(); // add this line here

    return mailSender;

}

// in MailService.java inject the configs above by adding them as constructor parameters:
private final JavaMailSender secondaryJavaMailSender;
private final JavaMailSender javaMailSender;

public MailService(@Qualifier("primaryMailSender") JavaMailSender javaMailSender
@Qualifier("secondaryMailSender") JavaMailSender secondaryJavaMailSender) {
    this.javaMailSender = javaMailSender;
    this.secondaryJavaMailSender = secondaryJavaMailSender;
}
