通过Javamail在MySql表中存储数据失败

Question

如何将我通过javamail编写的消息存储到MySQL表中？我已经配置了james服务器配置文件以连接到MySQL服务器(使用数据源元素名称maildb)，并且我将James服务器配置文件中的<inboxRepository>元素更改为

<inboxRepository>
  <repository destinationURL="db://maildb/spammer/"
    type="MAIL"/>      
</inboxRepository>

但我仍然无法读取MySql邮件数据库中垃圾邮件发送者表的收件箱列中的消息。

下面是我的javamail类：

import java.io.IOException;
import java.io.PrintWriter;
import java.util.Properties;
import javax.mail.*;
import javax.mail.internet.*;

public class mail{

  public static void main(String[] argts){
    String to = "red@localhost";
    String from = "blue@localhost";
    String subject = "jdk";
    String body = "Down to wind";

    if ((from != null) && (to != null) 
      && (subject != null)  && (body != null)) 
    // we have mail to send
    {
      try {
        Properties props = new Properties();

        props.put("mail.host", "127.0.0.1 ");
        props.put("mail.smtp.auth","true");

        Session session = 
          Session.getInstance(props, new javax.mail.Authenticator() {

          protected PasswordAuthentication getPasswordAuthentication() {
            return new PasswordAuthentication("blue", "blue");
          }
        });
        Message message = new MimeMessage(session);
        message.setFrom(new InternetAddress(from));
        Address[] add={ new InternetAddress(to) };
        message.setRecipients(Message.RecipientType.TO,add);
        message.setSubject(subject);
        message.setContent(body, "text/plain");
        message.setText(body);
        Transport.send(message);

        System.out.println
          ("<b>Thank you. Your message to "+to+" was successfully sent.</b>");

      } catch (Throwable t) {
        t.printStackTrace();
      }
    }
  }
}

我在这里做错了什么，我如何从MySQL中的垃圾邮件发送者表中读取邮件？

也许你使用了错误的数据库地址: destinationURL="db://maildb/spammer/“I propose change to destinationURL=" mysql ://maildb/spammer/”如果目标当然是mysql数据库的话。
