javaMail实现邮件发送

平常我们在做登陆注册的时候需要需要对邮箱进行验证，向邮箱发送验证信息。下面是我在做注册的时候向邮箱发送验证码代码。

邮箱校验正则

邮箱匹配规则：boolean mflag = mail.matches("^\\s*\\w+(?:\\.{0,1}[\\w-]+)*@[a-zA-Z0-9]+(?:[-.][a-zA-Z0-9]+)*\\.[a-zA-Z]+\\s*$");

邮箱发送入口

if(!mflag){
	result.setCode("-1");
	result.setmessage("邮箱格式验证不正确");
}else {
	//获取随机的六位数字 用于发送验证码
	String identifyingCode = SendEmailUtils.generatePassword();
	
	//拼装邮件内容   发送邮件的具体内容
	String emailcontent = getEmailContent4RegEmail(identifyingCode);
	
        //将验证码放入缓存服务器中memcache 
	MemcacheUtil.set(mail, 30, identifyingCode);
	
	//邮件服务器地址  从配置文件中读取邮件服务器地址
	String mailHost = SendEmailUtils.getPropValue("mail.smtp.host");
	
	//发送人邮箱     <span style="font-family: Arial, helvetica, sans-serif;">从配置文件中读取发送人邮箱</span>
	String mailEmail = SendEmailUtils.getPropValue("mail.smtp.email");
	
	//邮箱用户名     从配置文件中读取发送人邮箱用户名
	String mailUser = SendEmailUtils.getPropValue("mail.smtp.user");
	
	//邮箱密码      从配置文件中读取发送人邮箱密码
	String mailPassword = SendEmailUtils.getPropValue("mail.smtp.password");
	
	//邮件主题
	String title = "****邮箱注册";
	
	//发送邮箱  参数包括  发送目的地邮箱    发送人邮箱   邮件主题  邮件内容  邮件服务器  发送人邮箱用户名  发送人邮箱密码  是否是html格式
	new SendEmailUtils().send(mail, mailEmail, title, emailContent,
			mailHost, mailUser, mailPassword, true);
	
	Map<String, String> reMap = new HashMap<String, String>();
	
	reMap.put("sendCode", identifyingCode);
	
	result.setData(reMap);
	result.setCode("1");
	result.setMessage("发送成功");
}

拼装邮件内容（html格式的）

private String getEmailContent4RegEmail(String identifyingCode) {
		stringbuilder emailContent = new StringBuilder()
		.APPend("您在***进行邮箱注册操作的验证码为：<span style=\"color: #F3750F;font-weight: bold;font-size: larger;font-family: cursive;\">")
		.append(identifyingCode).append("</span><br/>")
		.append("此验证码只能使用一次，验证成功自动失效；<br/>")
		.append("<p style=\"font-size: small;color: gray;\">")
		.append("(请在10分钟内完成验证，10分钟后验证码失效，您需要重新进行验证。感谢您对***的支持。)<br/>")
		.append("如果您错误的收到了本电子邮件，请您忽略上述内容<br/>").append("</p>");
		return emailContent.toString();
	}
