Java實現注冊時發送激活郵件+激活，java注冊時

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 javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.servlet.ModelAndView;

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);//調用激活方法
                mav.setViewName("register/activate_success");
            } catch (ServiceException e) {
                request.setAttribute("message" , e.getMessage());
                mav.setViewName("register/activate_failure");
            }
