Java는 사용자가 등록할 때 이메일 활성화를 어떻게 구현합니까?-java지도 시간-php.cn

등록 중 활성화 이메일 전송 및 활성화의 Java 구현 예

최근 프로젝트에서 분리되어 다음 번에도 쉽게 사용할 수 있도록 등록 이메일 활성화 기능을 구성했습니다

1.RegisterController.java

package com.app.web.controller;

import javax.annotation.Resource;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.servlet.ModelAndView;
import com.app.service.impl.RegisterValidateService;
import com.app.tools.ServiceException;
 
@Controller
public class RegisterController {
 
  @Resource
  private RegisterValidateService service;
 
  @RequestMapping(value="/user/register",method={RequestMethod.GET,RequestMethod.POST})
  public ModelAndView load(HttpServletRequest request,HttpServletResponse response) throws ParseException{
    String action = request.getParameter("action");
    ModelAndView mav=new ModelAndView();
    if("register".equals(action)) {
      //注册
      String email = request.getParameter("email");
      service.processregister(email);//发邮箱激活
      mav.addObject("text","注册成功");
      mav.setViewName("register/register_success");
    }
    else if("activate".equals(action)) {
      //激活
      String email = request.getParameter("email");//获取email
      String validateCode = request.getParameter("validateCode");//激活码
      try {
        service.processActivate(email , validateCode);//调用激活方法
        mav.setViewName("register/activate_success");
      } catch (ServiceException e) {
        request.setAttribute("message" , e.getMessage());
        mav.setViewName("register/activate_failure");
      }
    }
    return mav;
