[Java教程]Java实现注册时发送激活邮件+激活


最近从项目分离出来的注册邮箱激活功能,整理一下,方便下次使用

1.RegisterController.java

package com.app.web.controller;import java.text.ParseException;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;@Controllerpublic 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;  }  }

 

2.RegisterValidateService.java

3.UserModel.java

4.SendEmail.java
