//实现邮件发送的方法
public static void sendMsg(String to ,String subject ,String content) throws Exception{
	Properties props = new Properties();
	props.setProperty("mail.smtp.host", "smtp.163.com");  //设置主机地址   smtp.qq.com    smtp.sina.com
	
	props.setProperty("mail.smtp.auth", "true");//认证 
	
	//2.产生一个用于邮件发送的Session对象
	Session session = Session.getInstance(props);
	
	//3.产生一个邮件的消息对象
	MimeMessage message = new MimeMessage(session);
	
	//4.设置消息的发送者
	Address fromAddr = new InternetAddress("[email protected]");
	message.setFrom(fromAddr);
	
	//5.设置消息的接收者

	//TO 直接发送  CC抄送    BCC密送
	message.setRecipient(RecipientType.TO, toAddr);
	
	//6.设置主题
