protected static String host = "true";
protected static String auth = "smtp.163.com";
protected static String user = "gonggao_1@163.com"; //发件人账号
protected static String password = "adccatarc2015"; //发件人密码

        final Properties props = new Properties(); // 配置发送邮件的环境属性
        
        props.put("mail.smtp.auth", host);// 表示SMTP发送邮件，需要进行身份验证

        props.put("mail.user", user); // 发件人的账号
        props.put("mail.password", password);  // 访问SMTP服务时需要提供的密码

        Authenticator authenticator = new Authenticator() {

		try {

	        // 设置收件人
	        InternetAddress to = new InternetAddress(addresseeNum);
	        message.setRecipient(RecipientType.TO, to);

	        // 设置邮件标题
	        message.setSubject("厂商代码申请通过");

	        // 设置邮件的内容体
	        message.setContent("企业用户您好！<br/>您的登录账号："+loginNum+"密码："+passwords+"厂商代码："+enterpriseCode, "text/html;charset=UTF-8");

	        // 发送邮件
	        Transport.send(message);
		} catch (AddressException e) {
			e.printStackTrace();
		} catch (MessagingException e) {
			e.printStackTrace();
		}
      
    }

以上是一个简单的邮件发送的方法需要引入javax.mail
