Java中发送带抄送的邮件可以通过使用JavaMail API中的Message类的setRecipients()方法来设置收件人和抄送人。以下是一个示例代码:
```java
import java.util.Properties;
import javax.mail.*;
import javax.mail.internet.*;
public class SendEmail {
public static void main(String[] args) throws Exception {
String to = "recipient@example.com";
String cc = "cc@example.com";
String from = "sender@example.com";
String password = "password";
Properties props = new Properties();
props.put("mail.smtp.auth", "true");
props.put("mail.smtp.starttls.enable", "true");
props.put("mail.smtp.host", "smtp.gmail.com");
props.put("mail.smtp.port", "587");
Session session = Session.getInstance(props, new javax.mail.Authenticator() {
protected PasswordAuthentication getPasswordAuthentication() {
return new PasswordAuthentication(from, password);
}
});
Message message = new MimeMessage(session);
message.setFrom(new InternetAddress(from));
message.setRecipients(Message.RecipientType.TO, InternetAddress.parse(to));
message.setRecipients(Message.RecipientType.CC, InternetAddress.parse(cc));
message.setSubject("Testing email with CC");
message.setText("Hello,\n\nThis is a test email with CC.");
Transport.send(message);
System.out.println("Email sent successfully.");
}
}
```
如果抄送人没有收到邮件,可能是由于以下原因导致:
1. 抄送人的邮件地址不正确或者被屏蔽,建议再次确认抄送人的邮件地址是否正确。
2. 邮件可能被归类为垃圾邮件,建议查看抄送人的垃圾邮件文件夹中是否有该邮件。
3. 邮件发送失败,可以查看JavaMail API返回的错误信息以及邮件服务器的日志信息来定位问题所在。
