Java 注冊時發(fā)送激活郵件和激活的實(shí)現(xiàn)示例

最近從項目分離出來的注冊郵箱激活功能，整理一下，方便下次使用

1.RegisterController.java

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)) {
      //注冊
      String email = request.getParameter("email");
      service.processregister(email);//發(fā)郵箱激活
      mav.addObject("text","注冊成功");
      mav.setViewName("register/register_success");
    }
    else if("activate".equals(action)) {
      //激活
      String email = request.getParameter("email");//獲取email
      String validateCode = request.getParameter("validateCode");//激活碼
      try {
        service.processActivate(email , validateCode);//調(diào)用激活方法
        mav.setViewName("register/activate_success");
      } catch (ServiceException e) {
        request.setAttribute("message" , e.getMessage());
