我正在尝试通过我的Java Mail应用程序向我的朋友发送邮件.我能够成功完成,但邮箱中的接收者列显示完整的电子邮件地址,而不是发件人的姓名.我尝试更改各种参数,但邮箱仍会显示完整的电子邮件地址,而不是发件人的姓名.

使用此方法发送消息:

 public void send(String key){
    String to=key;
    String from="mygmailid";
    String subject="wassp";
    String text="Hello";
    Properties props=new Properties();

    props.put("mail.smtp.host", "smtp.gmail.com");
    props.put("mail.smtp.user", "myname");
    props.put("mail.smtp.socketFactory.port", "465");
    props.put("mail.smtp.socketFactory.class","javax.net.ssl.SSLSocketFactory");
    props.put("mail.smtp.auth", "true");
    props.put("mail.smtp.port", "465");
    Session mailSession=Session.getDefaultInstance(props);
    Message simpleMessage=new MimeMessage(mailSession);

    InternetAddress fromAddress=null;
    InternetAddress toAddress=null;

    try{
        fromAddress=new InternetAddress(from);
        toAddress=new InternetAddress(to);
    }
    catch(AddressException e){
        e.printStackTrace();
    }

    try{
        simpleMessage.setFrom(fromAddress);
        simpleMessage.setRecipient(RecipientType.TO,toAddress);
        simpleMessage.setSubject(subject);
        simpleMessage.setText(text);

        transport.connect("smtp.gmail.com",465, "myid@gmail.com", "mygmailpassword");
        transport.sendMessage(simpleMessage, simpleMessage.getAllRecipients());
        transport.close();  

    }
    catch(MessagingException e){
        e.printStackTrace();
    }
}

我将此方法称为:

public static void main(String[] args) {
    MailSender mailer=new MailSender();
    mailer.send("friendmail@gmail.com");
}

是否可以向Java系统属性添加新值.如果有任何可以在Java系统属性中引入具有相应值的新密钥.

我试图在preparedStatement中使用to_date在oracle数据库中输入日期,但是我收到错误.

代码片段:

sql = "select Identifier from metadata where content_cdate >=to_date(?,'dd-mm-yyyy') and content_cdate < to_date(?,'dd-mm-yyyy') and status='published' and content_mdate is null";

ps.setString(1, commonUtil.dateToString(startTime));

dateToString方法返回如下值:2012-01-01 12:00:00

错误:

[Oracle][ODBC][Ora]ORA-01861: literal does not match format string

请指教.
