spring-mybatis实现注册通过邮箱发送激活码激活注册用户
网站用户注册：
主要实现如下两个功能:
1、用户在网站上注册完成后给用户发一封邮件。
2、用户通过邮件激活后才可以登录。
思路：
首先需要一个思路:
用户在前台点击注册，向controller提交请求，把用户提交过来的信息封装成一个user(需要的信息有name,pwd,email这3个是用户填写的,我们帮用户生成的是id和一个邮箱激活链接地址的唯一标识码acode，还要一个用来识别用户是否已经点击链接的变量active)。 如果用户点击了链接后，我们会将用户的状态修改为true【对应的“”1”】，当我们登入时，会根据返会的actived状态，来判断用户是否已经激活了账户，若未激活，则登录不进去，否则，则可以；
并且不能使用该邮箱重复注册用户，所以每次注册用户时，都会先通过邮箱查询该邮箱是否已经注册过了，没有，则可以注册，否则不行。
用户点了激活链接后，再自动跳转到登录页面！
1：.POM.xml中导入javaxmail需要的依赖
2：controller类
package com.chinasofti.controller; import com.chinasofti.pojo.User; import com.chinasofti.service.UserService; import com.chinasofti.util.EmailUtils; import com.chinasofti.util.GenerateLinkUtils; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.stereotype.Controller; import org.springframework.web.bind.annotation.RequestMapping; import javax.servlet.http.HttpServletResponse; import javax.servlet.http.HttpSession; import java.io.IOException; import java.util.UUID; @Controller @RequestMapping("email") public class UserController { @Autowired private UserService userService; @RequestMapping("toregist") public String toemail() { return "regist"; } @RequestMapping("login") public String login(){ return "login"; } @RequestMapping("/regist") public void regist(User user, HttpSession httpSession, HttpServletResponse response) { user.setActivated(false); //刚注册默认是没有激活状态 user.setCodeUrl(UUID.randomUUID().toString()); //注册用户 User user1=userService.findUserByEmail(user.getEmail()); if (user1==null) { userService.saveUser(user); } else { throw new RuntimeException("该邮箱已注册"); } //查看是否注册成功，为实体类User的id赋值 User findUser = userService.findUserByEmail(user.getEmail()); if (findUser != null) { user.setId(findUser.getId()); } else { throw new RuntimeException("注册用户失败"); } //注册成功后，发送账户激活链接 httpSession.setAttribute("user", user); EmailUtils.sendAccountActivateEmail(user); try { response.setContentType("text/html;charset=utf-8"); response.getWriter().write("激活邮件已经发送，请注意提醒查收"); } catch (IOException e) { e.printStackTrace(); } } @RequestMapping("/activate") public void activate(String id, String checkCode, HttpServletResponse response) { int idInt = Integer.parseInt(id); //根据用户id查找用户 User user = userService.findUserById(idInt); //验证无误，状态更改为1，即激活 if (GenerateLinkUtils.verifyCheckcode(user, checkCode)) { //修改状态 int activated = 1; userService.updateActivated(activated, idInt); user.setActivated(true); try { response.setContentType("text/html;charset=utf-8"); response.getWriter().write("恭喜，激活成功！"); } catch (IOException e) { e.printStackTrace(); } } } }
3：service类
package com.chinasofti.service; import com.chinasofti.dao.UserDao; import com.chinasofti.pojo.User; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.stereotype.Service; @Service public class UserService { @Autowired private UserDao userDao; public void saveUser(User user) { userDao.saveUser(user); } public User findUserByEmail(String email) { return userDao.findUserByEmail(email); } public User findUserById(int idInt) { return userDao.findUserById(idInt); } public void updateActivated(int activated, int idInt) { userDao.updateActivated(activated,idInt); }
}
4：dao层
package com.chinasofti.dao; import com.chinasofti.pojo.User; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.stereotype.Repository; @Repository public class UserDao { @Autowired private UserMapper userMapper; public User findUserByEmail(String email) { return userMapper.findUserByEmail(email); } public User findUserById(int idInt) { return userMapper.findUserById(idInt); } public void saveUser(User user) { userMapper.saveUser(user); } public void updateActivated(int activated, int idInt) { userMapper.updateActivated(activated,idInt); } }5：register.jsp页面
