提取码：cJxQ其中对于短信登录这块代码已经做了优化，通过Redis实现短信验证码登录，想要按照Session方式进行登录来学习Session的短信验证码登录流程的，可以将工程相关代码按下述的代码进行修改调整。
一、User类
package com.hmdp.entity;import com.baomidou.mybatisplus.annotation.IdType;
import com.baomidou.mybatisplus.annotation.TableId;
import com.baomidou.mybatisplus.annotation.TableName;
import lombok.Data;
import lombok.EqualsAndHashCode;
import lombok.experimental.Accessors;
import java.io.Serializable;
import java.time.LocalDateTime;@Data
@EqualsAndHashCode(callSuper = false)
@Accessors(chain = true)
@TableName("tb_user")
public class User implements Serializable {private static final long serialVersionUID = 1L;/*** 主键*/@TableId(value = "id", type = IdType.AUTO)private Long id;/*** 手机号码*/private String phone;/*** 密码，加密存储*/private String password;/*** 昵称，默认是随机字符*/private String nickName;/*** 用户头像*/private String icon = "";/*** 创建时间*/private LocalDateTime createTime;/*** 更新时间*/private LocalDateTime updateTime;}
二、ThreadLocal类
package com.hmdp.utils;import com.hmdp.entity.User;public class UserHolder {private static final ThreadLocal<User> tl = new ThreadLocal<>();public static void saveUser(User user){tl.set(user);}public static User getUser(){return tl.get();}public static void removeUser(){tl.remove();}
}
三、用户业务逻辑接口
package com.hmdp.service;import com.baomidou.mybatisplus.extension.service.IService;
import com.hmdp.dto.LoginFormDTO;
import com.hmdp.dto.Result;
import com.hmdp.entity.User;import javax.servlet.http.HttpSession;public interface IUserService extends IService<User> {Result sendCode(String phone, HttpSession session);Result login(LoginFormDTO loginForm, HttpSession session);
}
四、用户业务逻辑接口实现类
package com.hmdp.service.impl;import cn.hutool.core.util.RandomUtil;
import com.baomidou.mybatisplus.extension.service.impl.ServiceImpl;
import com.hmdp.dto.LoginFormDTO;
import com.hmdp.dto.Result;
import com.hmdp.entity.User;
import com.hmdp.mapper.UserMapper;
import com.hmdp.service.IUserService;
import com.hmdp.utils.RegexUtils;
import lombok.extern.slf4j.Slf4j;
import org.springframework.data.redis.core.StringRedisTemplate;
import org.springframework.stereotype.Service;
import javax.annotation.Resource;
import javax.servlet.http.HttpSession;
import static com.hmdp.utils.SystemConstants.USER_NICK_NAME_PREFIX;@Slf4j
@Service
public class UserServiceImpl extends ServiceImpl<UserMapper, User> implements IUserService {@Resourceprivate StringRedisTemplate stringRedisTemplate;@Overridepublic Result sendCode(String phone, HttpSession session) {// 1.校验手机号if (RegexUtils.isPhoneInvalid(phone)) {// 2.如果不符合，返回错误信息return Result.fail("手机号格式错误！");}// 3.符合，生成验证码String code = RandomUtil.randomNumbers(6);// 4.保存验证码到 sessionsession.setAttribute("code:" + phone, code);// 5.发送验证码log.debug("发送短信验证码成功，验证码：{}", code);// 返回okreturn Result.ok();}@Overridepublic Result login(LoginFormDTO loginForm, HttpSession session) {// 1.校验手机号String phone = loginForm.getPhone();if (RegexUtils.isPhoneInvalid(phone)) {// 2.如果不符合，返回错误信息return Result.fail("手机号格式错误！");}// 2. 校验验证码Object cacheCode = session.getAttribute("code:" + loginForm.getPhone());String code = loginForm.getCode();// 3. 不一致则报错if (cacheCode == null || !cacheCode.toString().equals(code)) {return Result.fail("验证码错误");}// 4. 一致，则根据手机号查询用户User user = query().eq("phone", phone).one();// 5. 判断用户是否存在if (user == null) {// 6. 不存在则创建用户并保存createUserWithPhone(phone);}// 7. 保存用户信息到session中session.setAttribute("user", user);// 8.返回tokenreturn Result.ok();}private User createUserWithPhone(String phone) {// 1.创建用户User user = new User();user.setPhone(phone);user.setNickName(USER_NICK_NAME_PREFIX + RandomUtil.randomString(10));// 2.保存用户save(user);return user;}
}
五、用户控制层
package com.hmdp.controller;import com.hmdp.dto.Result;
import com.hmdp.service.IUserInfoService;
import com.hmdp.service.IUserService;
import lombok.extern.slf4j.Slf4j;
import org.springframework.web.bind.annotation.PostMapping;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.bind.annotation.RestController;
import javax.annotation.Resource;
import javax.servlet.http.HttpSession;@Slf4j
@RestController
@RequestMapping("/user")
public class UserController {@Resourceprivate IUserService userService;/*** 发送手机验证码*/@PostMapping("code")public Result sendCode(@RequestParam("phone") String phone, HttpSession session) {// 发送短信验证码并保存验证码return userService.sendCode(phone, session);}/*** 登录功能* @param loginForm 登录参数，包含手机号、验证码；或者手机号、密码*/@PostMapping("/login")public Result login(@RequestBody LoginFormDTO loginForm, HttpSession session){// 实现登录功能return userService.login(loginForm, session);}@GetMapping("/me")public Result me(){// 获取当前登录的用户并返回User user = UserHolder.getUser();return Result.ok(user);}
}六、用户登录拦截器
package com.hmdp.utils;import com.hmdp.entity.User;
import org.springframework.web.servlet.HandlerInterceptor;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import javax.servlet.http.HttpSession;public class LoginInterceptor implements HandlerInterceptor {@Overridepublic boolean preHandle(HttpServletRequest request, HttpServletResponse response, Object handler) throws Exception {// 1. 获取SessionHttpSession session = request.getSession();// 2. 获取session中的用户Object user = session.getAttribute("user");// 3. 判断用户是否存在if (user == null) {// 4. 不存在则拦截并返回401状态码response.setStatus(401);return false;}// 5. 存在则保存用户信息到ThreadLocalUserHolder.saveUser((User) user);return true;}@Overridepublic void afterCompletion(HttpServletRequest request, HttpServletResponse response, Object handler, Exception ex) throws Exception {// 移除用户UserHolder.removeUser();}
}
七、拦截器配置类
package com.hmdp.config;import com.hmdp.utils.LoginInterceptor;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.servlet.config.annotation.InterceptorRegistry;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurer;@Configuration
public class MvcConfig implements WebMvcConfigurer {@Overridepublic void addInterceptors(InterceptorRegistry registry) {// 登录拦截器registry.addInterceptor(new LoginInterceptor()).excludePathPatterns("/shop/**","/voucher/**","/shop-type/**","/upload/**","/blog/hot","/user/code","/user/login");}
}
八、隐藏敏感信息的代码调整
上述代码中存入Session中的用户信息涉及到了很多的敏感字段，如手机号、密码等，会有安全风险，所以对代码优化如下：
package com.hmdp.dto;import lombok.Data;@Data
public class UserDTO {private Long id;private String nickName;private String icon;
}
package com.hmdp.utils;import com.hmdp.dto.UserDTO;public class UserHolder {private static final ThreadLocal<UserDTO> tl = new ThreadLocal<>();public static void saveUser(UserDTO user){tl.set(user);}public static UserDTO getUser(){return tl.get();}public static void removeUser(){tl.remove();}
}
package com.hmdp.controller;import com.hmdp.dto.LoginFormDTO;
import com.hmdp.dto.Result;
import com.hmdp.dto.UserDTO;
import com.hmdp.service.IUserInfoService;
import com.hmdp.service.IUserService;
import com.hmdp.utils.UserHolder;
import lombok.extern.slf4j.Slf4j;
import org.springframework.web.bind.annotation.*;
import javax.annotation.Resource;
import javax.servlet.http.HttpSession;@Slf4j
@RestController
@RequestMapping("/user")
public class UserController {@Resourceprivate IUserService userService;@Resourceprivate IUserInfoService userInfoService;/*** 发送手机验证码*/@PostMapping("code")public Result sendCode(@RequestParam("phone") String phone, HttpSession session) {// 发送短信验证码并保存验证码return userService.sendCode(phone, session);}/*** 登录功能* @param loginForm 登录参数，包含手机号、验证码；或者手机号、密码*/@PostMapping("/login")public Result login(@RequestBody LoginFormDTO loginForm, HttpSession session){// 实现登录功能return userService.login(loginForm, session);}@GetMapping("/me")public Result me(){// 获取当前登录的用户并返回UserDTO user = UserHolder.getUser();return Result.ok(user);}
}package com.hmdp.utils;import com.hmdp.dto.UserDTO;
import org.springframework.web.servlet.HandlerInterceptor;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import javax.servlet.http.HttpSession;public class LoginInterceptor implements HandlerInterceptor {@Overridepublic boolean preHandle(HttpServletRequest request, HttpServletResponse response, Object handler) throws Exception {// 1. 获取SessionHttpSession session = request.getSession();// 2. 获取session中的用户Object user = session.getAttribute("user");// 3. 判断用户是否存在if (user == null) {// 4. 不存在则拦截并返回401状态码response.setStatus(401);return false;}// 5. 存在则保存用户信息到ThreadLocalUserHolder.saveUser((UserDTO) user);return true;}@Overridepublic void afterCompletion(HttpServletRequest request, HttpServletResponse response, Object handler, Exception ex) throws Exception {// 移除用户UserHolder.removeUser();}
}
