java Java发送电子邮件非法分号？

Java Send Email Illegal semicolon?

提问by espresso_coffee

I'm trying to send emails with java from database. After I run my main method for some reason I'm getting this error:

我正在尝试从数据库中使用 java 发送电子邮件。由于某种原因运行我的主要方法后，我收到此错误：

Exception in thread "main" javax.mail.internet.AddressException: Illegal semicolon, not in group in string ``[email protected];[email protected];[email protected];[email protected];[email protected]'' at position 23
    at javax.mail.internet.InternetAddress.parse(InternetAddress.java:929)

I'm assuming that my array list is built wrong. Here is my code:

这是我的 main.java：

public class Main {
    public static void main(String[] args) throws Exception {
        TestSendEmailD dao=new TestSendEmailD();
        List<TestSendEmails> list=dao.getTestSendEmails();
        EmailSender sender=new EmailSender();
        sender.sendEmail(list);
    }
}

Can anyone help with this? Thanks in advance.

有人能帮忙吗？提前致谢。

By default it parse with comma(,) separated email addresses and not with semicolon (;),

默认情况下，它使用逗号 ( ,) 分隔的电子邮件地址而不是分号 ( ;) 进行解析，

InternetAddress[] parse = InternetAddress.parse("[email protected],[email protected]");
System.out.println(parse[0].getAddress());

OUTPUT:

输出：

[email protected]
