java - 如何克服异常-在Java中发送电子邮件时字符串``'中的非法地址

这是我的代码：

prop.load(new FileInputStream("config.properties"));
        String emailTo = prop.getProperty("To");
        String emailCC = prop.getProperty("CC");
        String emailBCC = prop.getProperty("BCC")

String[] to = emailTo.trim().split(",");
        String[] cc = emailCC.trim().split(",");
        String[] bcc = emailBCC.trim().split(",");

 --- Note: Value of CC and BCC is blank in properties file

config.properties

To = [email protected]
CC =
BCC =

-我尝试过，我认为这是因为CC和BCC的值为空，但是如何解决它。我不知道。

发生异常：

DEBUG: setDebug: JavaMail version 1.3.1
javax.mail.internet.AddressException: Illegal address in string ``''
    at javax.mail.internet.InternetAddress.<init>(InternetAddress.java:68)
    at com.neosoft.reporting.SendEmail.sendMail(SendEmail.java:165)
    at com.neosoft.reporting.SendEmail.execute(SendEmail.java:60)

    at sun.reflect.NativeMethodAccessorImpl.invoke(Unknown Source)
    at sun.reflect.DelegatingMethodAccessorImpl.invoke(Unknown Source)
    at java.lang.reflect.Method.invoke(Unknown Source)

使用参数传递的sendMail（）声明：

如果CC和BCC的值在属性文件中为空，那么我应该在方法中传递什么。

SendEmail.sendMail("[email protected]", "xxxx", "smtp.gmail.com",
                            "465", "true", "true", true,
                            javax.net.ssl.SSLSocketFactory.class.getCanonicalName(),
                            "false", to, cc, bcc, "Automation Test Report",
                            "Hi \n Here is your test report of current run that was initiated.",
                            path, reportFileName);
}

public  static boolean sendMail(String userName, String passWord, String host, String port,
                String starttls, String auth, boolean debug, String socketFactoryClass,
                String fallback, String[] to, String[] cc, String[] bcc,
                String subject, String text, String attachmentPath, String attachmentName)

最佳答案

首先像您一样从CC文件中获取BCC和config.properties

 String emailTo = prop.getProperty("To");
 String emailCC = prop.getProperty("CC");
 String emailBCC = prop.getProperty("BCC")

然后检查它们是否像NULL

String[] cc;
String[] bcc;
if(emailCC.length() != 0){
    cc = emailCC.trim().split(",");
}else if(emailBCC.length() != 0){
    bcc = emailBCC.trim().split(",");
}

当cc和bcc是null时，请在sendMail（）中添加以下条件：

for(int i = 0; i < cc.length; i++) {
    if(!cc[i].isEmpty())
        message.addRecipient(Message.RecipientType.CC, new InternetAddress(cc[i]));
}
for(int i = 0; i < bcc.length; i++) {
    if(!bcc[i].isEmpty())
        msg.addRecipient(Message.RecipientType.BCC, new InternetAddress(bcc[i]));
}

我希望这能解决您的问题。
