通过Servlet发送电子邮件时，在消息正文中添加链接

Question

在我使用jsp和servlet的Web申请人中，有一个成员注册，但是当成员忘记密码时，我想进行帐户恢复，当他们单击该链接并且我拥有此servlet时，它将发送一个链接以重置其密码。可以在需要时向用户发送电子邮件，但我不知道设计电子邮件的技术，可以像其他所有重置密码电子邮件一样在邮件正文中附加链接和图像。

    }else{
        response.sendRedirect("error.jsp");
    }

    out.close();

}
}

something like this..

我所能做的就是使用此代码输入一些短信。
