Question

电子邮件仅会发送到String[] to数组中的最后一个电子邮件地址。我打算发送到添加到阵列的所有电子邮件地址。我怎样才能做到这一点？

public void sendMail(String from, String[] to, String subject, String msg, List attachments) throws MessagingException {

    // Creating message  
    sender.setHost("smtp.gmail.com");
    MimeMessage mimeMsg = sender.createMimeMessage();
    MimeMessageHelper helper = new MimeMessageHelper(mimeMsg, true);
    Properties props = new Properties();
    props.put("mail.smtp.starttls.enable", "true");
    props.put("mail.smtp.auth", "true");
    props.put("mail.smtp.port", "425");

    Session session = Session.getDefaultInstance(props, null);

    helper.setFrom(from);

    helper.setTo(to);

    helper.setSubject(subject);
    helper.setText(msg + "<html><body><h1>hi welcome</h1><body></html", true);

    Iterator it = attachments.iterator();

    while (it.hasNext()) {
        FileSystemResource file = new FileSystemResource(new File((String) it.next()));
        helper.addAttachment(file.getFilename(), file);
    }

    // Sending message  
    sender.send(mimeMsg);
}

Answer 1

使用以逗号分隔的地址列表：

helper.setTo(to1,to2,to3....);

Answer 2

更好的方法是创建一个包含多个收件人地址的数组。

function fillStreetLocationSelect() {
    $.ajax({
        async: true,
        url: web + "/FillStreetLocationSelect",
        dataType: "json",
        method: "POST",
        data: JSON.stringify(hazard),
        contentType: "application/json; charset=utf-8",
        success: function (data) {
            /*   */
        }
    });
}

Answer 3

就这样尝试吧。

helper.setTo(InternetAddress.parse("email1@test.com,email2@test.com"))

Answer 4

将所有电子邮件ID添加到String []数组中

public String[] sendEmailIds() {
String[] emailIds = new String[4];
emailIds[0] = "abc@mail.com";
emailIds[1] = "deg@mail.com";
emailIds[2] = "sgh@mail.com";
emailIds[3] = "hht@mail.com";
return emailIds;
}

SimpleMailMessage mailMessage = new SimpleMailMessage();
mailMessage.setTo(sendEmailIds());
mailMessage.setSubject(subject);
mailMessage.setText(message);
mailMessage.setFrom(fromEmailAddress);
javaMailSender.send(mailMessage);

Answer 5

You can try this, instead of

helper.setTo(to);

String multipleEmailIds = "abc@abc.com, abc@abc.com"
mimeMsg.setRecipients(Message.RecipientType.TO, InternetAddress.parse(multipleEmailIds ));

Answer 6

我认为更好的方法是在spring.xml文件中将“to”属性声明为数组，传递值并使用Deinum在评论中建议的方法setTo(string[])。进程在xml文件中将'to'定义为

<property name="to">
    <array>
    <value>abc@gmail.com</value>
    <value>xyz@gmail.com</value>
    </array>
</property>

现在为包含多个收件人地址的数组生成getter setter方法，并将其传递给setTo(String[])方法： -

helper.setTo(to);

Answer 7

它与SimpleMailMessage配合良好。像Siri

的答案

String[] to = {"user1@gmail.com", "user2@gmail.com"};
        
SimpleMailMessage simpleMailMessage = new SimpleMailMessage();
simpleMailMessage.setTo(to);
simpleMailMessage.setSubject("subject of mail");
simpleMailMessage.setText("content of mail");

try {
    javaMailSender.send(simpleMailMessage);
} catch (MailSendException e) {
     //...
}

Answer 8

<bean id="mailSender" class="org.springframework.mail.javamail.JavaMailSenderImpl">
      <property name="host" value="smtp.ccc.corp"/>
      <property name="port" value="25"/>
      <property name="javaMailProperties"><props>
        <prop key="mail.smtp.sendpartial">true</prop>
      </props></property>
</bean>

设置mail.smtp.sendpartial为真。我相信它的工作对你来说
