第六章登陆与注册 本章主要内容如下
登陆注册相关

<!DOCTYPE mapperPUBLIC "-//mybatis.org//DTD Mapper 3.0//EN""http://mybatis.org/dtd/mybatis-3-mapper.dtd"><mapper namespace="com.example.hospital.patient.wx.api.db.dao.UserDao"><!-- 添加患者账户 --><insert id="insertPatient" parameterType="com.example.hospital.patient.wx.api.db.pojo.UserEntity">UPSERT INTO HOSPITAL.PATIENT_USER (id,open_id,nickname,photo,sex,status,create_time) VALUES (NEXT VALUE FOR HOSPITAL.PATIENT_USER_SEQUENCE,#{openId},#{nickname},#{photo},#{sex},#{status},CURRENT_TIMESTAMP)</insert><!-- 检查用户是否已注册 --><select id="searchAlreadyRegistered" parameterType="String" resultType="Integer">SELECT idFROM HOSPITAL.PATIENT_USERWHERE open_id = #{openId}LIMIT 1</select><!-- 患者登录 --><select id="patientLogin" parameterType="map" resultType="com.example.hospital.patient.wx.api.db.pojo.UserEntity">SELECT id,open_id,nickname,photo,sex,status,create_timeFROM HOSPITAL.PATIENT_USERWHERE open_id = #{openId} AND password = #{password}</select></mapper>
以下是在com.example.hospital.patient.wx.api.db.dao.UserDao接口中声明相关DAO方法的代码：
public interface UserDao {/*** 插入用户实体对象到数据库中* @param entity 要插入的用户实体* @return 受影响的行数*/@Transactionalint insert(UserEntity entity);/*** 根据openId查询是否已经注册过* @param openId 用户的唯一标识openId* @return 如果已经注册返回对应的用户ID，如果未注册返回null*/Integer searchAlreadyRegistered(String openId);
}
服务层代吗
@Service public class UserServiceImpl implements UserService {@Value("${wechat.app - id}")private String appId;@Value("${wechat.app - secret}")private String appSecret;@Resourceprivate UserDao userDao;@Resourceprivate UserInfoCardDao userInfoCardDao;@Overridepublic HashMap<String, Object> loginOrRegister(String code, String nickname, String photo, String sex) {// 用临时授权兑换openIdString openId = this.getOpenId(code);HashMap<String, Object> map = new HashMap<>();// 是否为已注册用户Integer id = userDao.searchAlreadyRegistered(openId);if (id == null) {UserEntity entity = new UserEntity();entity.setOpenId(openId);entity.setNickname(nickname);entity.setPhoto(photo);entity.setSex(sex);userDao.insert(entity);map.put("success", true);map.put("message", "注册成功");map.put("userId", entity.getId());} else {map.put("success", true);map.put("message", "登录成功");map.put("userId", id);}return map;}private String getOpenId(String code) {// 这里应该是调用微信相关接口，根据code获取openId的逻辑// 例如使用http请求调用微信的API，这里只是模拟返回一个openIdreturn "mockOpenId";} }
以下是截图
然后服务层，和实现
