我想使用以下方法向多个收件人发送邮件:
message.addRecipient(Message.RecipientType.TO, String arg1);
要么
message.setRecipients(Message.RecipientType.TO,String arg1);
但令人困惑的是,在第二个参数中,如何传递多个地址,如:
message.addRecipient(Message.RecipientType.CC, "[email protected],[email protected],[email protected]");
要么
message.addRecipient(Message.RecipientType.CC, "[email protected];[email protected];[email protected]");
我也可以使用替代方法发送消息,但想知道上述方法的目的。如果我不能使用它(因为直到现在我还没有得到上述要求的任何答案)那么这个方法需要在邮件API中。
如果多次调用addRecipient
,它会将给定的收件人添加到给定时间(TO,CC,BCC)的收件人列表中
例如:
message.addRecipient(Message.RecipientType.CC, InternetAddress.parse("[email protected]"));
message.addRecipient(Message.RecipientType.CC, InternetAddress.parse("[email protected]"));
message.addRecipient(Message.RecipientType.CC, InternetAddress.parse("[email protected]"));
将3个地址添加到CC
如果您希望一次添加所有地址,您应该使用setRecipients
或addRecipients
并为其提供一组地址
Address[] cc = new Address[] {InternetAddress.parse("[email protected]"),
InternetAddress.parse("[email protected]"),
InternetAddress.parse("[email protected]")};
message.addRecipients(Message.RecipientType.CC, cc);
您还可以使用InternetAddress.parse
来解析地址列表
message.addRecipients(Message.RecipientType.CC,
InternetAddress.parse("[email protected],[email protected],[email protected]"));
您可以使用以下方法的n个收件人:
commons-email-1.3.1
如果你想使用MimeMessageHelper作为Cc发送
email.addTo( addressList );
您可以使用相同的方式添加多个收件人。
简单的方法
public static void sendSimpleMail() throws Exception {
Email email = new SimpleEmail();
email.setSmtpPort(587);
DefaultAuthenticator defaultAuthenticator = new DefaultAuthenticator( USER_NAME, PASSWORD );
email.setAuthenticator( defaultAuthenticator );
email.setDebug(false);
email.setHostName( MAIL_SERVER_NAME );
email.setFrom( USER_NAME );
email.setSubject("Hi");
email.setMsg("This is a test mail ... :-)");
//email.addTo( "[email protected]", "Yash" );
String[] toAddressList = { "[email protected]", "[email protected]" }
email.addTo( addressList );
email.setTLS(true);
email.setStartTLSEnabled( true );
email.send();
System.out.println("Mail sent!");
}
嗨,每个这个代码都适合我,请尝试使用此发送邮件给多个收件人
private String recipient = "[email protected] ,[email protected] ";
String[] recipientList = recipient.split(",");
InternetAddress[] recipientAddress = new InternetAddress[recipientList.length];
int counter = 0;
for (String recipient : recipientList) {
recipientAddress[counter] = new InternetAddress(recipient.trim());
counter++;
}
message.setRecipients(Message.RecipientType.TO, recipientAddress);
试试这种方式:
message.setRecipients(Message.RecipientType.TO, InternetAddress.parse("[email protected]"));
String address = "[email protected],[email protected]";
InternetAddress[] iAdressArray = InternetAddress.parse(address);
message.setRecipients(Message.RecipientType.CC, iAdressArray);
只需使用带有逗号分隔的多个地址的message.setRecipients方法:
message.setRecipients(Message.RecipientType.TO, InternetAddress.parse("[email protected],[email protected],[email protected]"));
message.setRecipients(Message.RecipientType.CC, InternetAddress.parse("[email protected],[email protected],[email protected]"));
只有一个地址也可以正常工作
message.setRecipients(Message.RecipientType.TO, InternetAddress.parse("[email protected]"));
您可以使用逗号分隔多个地址
if (cc.indexOf(',') > 0)
message.setRecipients(Message.RecipientType.CC, InternetAddress.parse(cc));
else
message.setRecipient(Message.RecipientType.CC, new InternetAddress(cc));
所以......花了好几个月,但仍然......你可以使用','作为分隔符,向多个收件人发送电子邮件
message.setRecipients(Message.RecipientType.CC, "[email protected],[email protected],[email protected]");
没关系。至少在JavaMail 1.4.5中
InternetAddress.Parse将成为你的朋友!请参阅下面的工作示例:
String to = "[email protected], [email protected], [email protected]";
String toCommaAndSpaces = "[email protected] [email protected], [email protected]";
msg.setRecipients(Message.RecipientType.CC,
InternetAddress.parse(to, true));
msg.setRecipients(Message.RecipientType.BCC,
InternetAddress.parse(toCommaAndSpaces, false));
互联网电子邮件地址格式(String[] mailAddressTo = new String[3];
mailAddressTo[0] = emailId_1;
mailAddressTo[1] = emailId_2;
mailAddressTo[2] = "[email protected]";
InternetAddress[] mailAddress_TO = new InternetAddress[mailAddressTo.length];
for (int i = 0; i < mailAddressTo.length; i++)
{
mailAddress_TO[i] = new InternetAddress(mailAddressTo[i]);
}
message.addRecipients(Message.RecipientType.TO, mailAddress_TO);ress_TO = new InternetAddress[mailAddressTo.length];
)
RFC 822
comma分开的地址序列
javax.mail - 1.4.7不允许使用(,)
。所以我们必须将逗号分隔的地址序列放入parse( String[] )
对象中。地址必须遵循RFC822语法。
InternetAddress
String toAddress = "[email protected],[email protected]"; InternetAddress.parse( toAddress );
分号分隔的地址序列«如果(;)
提供的分隔符为“;”然后使用split方法转换为String数组以使用以下函数。
group of address list
String[] addressList = { "[email protected]", "[email protected]" };
String toGroup = "[email protected];[email protected]";
String[] addressList2 = toGroup.split(";");
setRecipients(message, addressList);
完整示例:
public static void setRecipients(Message message, Object addresslist) throws AddressException, MessagingException {
if ( addresslist instanceof String ) { // CharSequence
message.setRecipients(Message.RecipientType.TO, InternetAddress.parse( (String) addresslist ));
} else if ( addresslist instanceof String[] ) { // String[] « Array with collection of Strings/
String[] toAddressList = (String[]) addresslist;
InternetAddress[] mailAddress_TO = new InternetAddress[ toAddressList.length ];
for (int i = 0; i < toAddressList.length; i++) {
mailAddress_TO[i] = new InternetAddress( toAddressList[i] );
}
message.setRecipients(Message.RecipientType.TO, mailAddress_TO);
}
}
