哪位大佬知道我点击邮箱里的激活邮件链接页面显示空白

Question

//3.激活邮件，邮件正文？
String content = "点击激活【报警信息系统】";
MailUtils.sendMail(user.getEmail(),content,"激活邮件");

@WebServlet("/activeUserServlet")
public class ActiveUserServlet extends HttpServlet {
protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
//1.获取激活码
String code = request.getParameter("code");
if (code != null){
//2.调用service完成激活
UserService service = new UserServiceImpl();
boolean flag = service.active(code);
//3.判断标记
String msg = null;
if (flag){
//激活成功
msg = "激活成功，请登录";
}else {
//激活失败
msg = "激活失败，请联系管理员！";
}
response.setContentType("text/html;charset=utf-8");
response.getWriter().write(msg);
}
}

protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {

}

}

你的网站部署到公网服务器了没有，端口号是默认的么，如果是本地服务器，显然外人无法使用，如果不是默认端口，显然链接打不开
String content = "<a href=你的网站并且包含验证码地址>点击激活【报警信息系统<./a>"
打开你的邮件，检查下发来的地址是不是正确。
