在 property.setProperty( "mail.smtp.host" ，host) 中获取语法错误;

Question

我得到下面一行的语法，而试图通过SMTP发送邮件。我尝试在谷歌，但没有得到任何相关的答案。

property.setProperty("mail.smtp.host"、主机);

代码:

public class SendMail {
//Recipient Mail id 
String to = "Receiver Mail ID";
//Sender Mail Id
String from = "Sender Mail ID";
//Sending email from the localhost
String host = "localhost";
//Get System Properties
Properties property = System.getProperties();
//Setup the mail server
property.setProperty("mail.smtp.host",host);
property.setProperty("mail.smtp.port" , "465");
//property.put("mail.smtp.auth", "true"); 
//Get the default session object
Session session = Session.getDefaultInstance(property);

try
{
    //Create a default MimeMessage object.
    MimeMessage message = new MimeMessage(session);
    //Set From: header field of the header
    message.setFrom(new InternetAddress(from));
    //Set To : header field of the header
    message.addRecipient(Message.RecipientType.TO, new InternetAddress(to));
    //Set Subject : header field
    message.setSubject("Automation Testing Report");
    //Create the Message part
    BodyPart messageBodypart = new MimeBodyPart();
    //Enter the message in the Mail Body
    messageBodypart.setText("***********Find the below for the Report****************");
    //Create a Multipart Message
    Multipart multipart = new MimeMultipart();
    //Set Text message part
    multipart.addBodyPart(messageBodypart);

    //Part two is attachment
    /*create the Message part*/
    messageBodypart = new MimeBodyPart();
    String filename = "E:\Project\jar\Selenium        Scripts\Hybrid_Driven\test-output\emailable-report.html";
    DataSource source = new FileDataSource(filename);
    messageBodypart.setDataHandler(new DataHandler(source));
    messageBodypart.setFileName(filename);
    //set the text message part
    multipart.addBodyPart(messageBodypart);
    //Send the complete message part
    message.setContent(multipart);

    //Send message 
    Transport.send(message);
    System.out.println("Mail has sent successfully");
}
catch(MessagingException mex)
{
    mex.printStackTrace();
}
}
}

请帮我解决这个问题

不能将java代码直接放入类中。它需要在方法中。编译器很乐意接受以下内容:

public class SendMail {
  ...
  //Get System Properties
  java.util.Properties property = System.getProperties();
  void doSomething()
  {
    property.setProperty("mail.smtp.host", host);
    property.setProperty("mail.smtp.port", "465");
    ...
  }
}
