java 注册时发送激活邮件和激活的实现示例

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;

@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;

}

}
