微信小程序实现lot开发06 与springboot结合建立登录与设备信息查看

前几天着重学习了关于微信小程序界面基础与事件的绑定，列表的渲染等知识。

我们先来挂代码：

@Data
public class User {
    private String Id;
    private String Name;
    private Integer Amount;
    private String Phone;
    private String password;
}

@Data
public class Device {
    private String Id;
    private boolean State;
    private boolean Lock;
    private String Info;
}

@Mapper
public interface UserMapper {
    //    登录
    @Select("select password from getmsqlconnection.user where Id=#{Id}")
    String login(@Param("Id") String Id,@Param("password") String password);
    //    注册
    @Insert("insert into getmsqlconnection.user values(#{user.Id},#{user.Name},#{user.Phone},#{user.Amount},#{user.password})")
    Boolean register(@Param("user") User user);
    //    修改密码
    @Update("update getmsqlconnection.user set password=#{password} where Id=#{Id}")
    Boolean updatePassword(@Param("Id") String Id,@Param("password") String password);
}


@Mapper
public interface DeviceMapper {
    @Select("select * from getmsqlconnection.device")
    List findAllDevice();
}

@RestController
public class UserController {
    @Autowired
    private UserService userService;

    
    @RequestMapping("/login")
    public R userLogin(@RequestParam("Id")String Id, @RequestParam("password")String password){
//        System.out.println("-------------"+Id+"||"+password+"--------------------");
        if (Id == null || password == null){
            return R.error("输入完整的账号密码！");
        }
        try {
            String userLogin = userService.userLogin(Id, password);
//            System.out.println("-------------"+userLogin+"----------");
            if (!userLogin.equals(password)){
                throw new SQLException("账号密码错误！");
            }
            return R.success(true);
        }catch (Exception e){
            return R.error("登录失败！");
        }
    }

    
    @RequestMapping("/register")
    @ResponseBody
    public R UserRegister(@RequestParam("Id") String Id,@RequestParam("Name")String Name,@RequestParam("Phone")String Phone,@RequestParam("password")String password){
        System.out.println("-----------微信小程序访问------------");
        if (Id == null || password == null)
            return R.error("请填写完整的用户信息！");
        String password1 = null;
        try {
            password1 = userService.userLogin(Id,password);
        }catch (Exception e){
            System.out.println("该账户没有注册过！");
            throw e;
        }
        try{
            if (password1 != null)
                throw new Exception("该账户名已经被使用！");
            User user = new User();
            user.setId(Id);
            user.setName(Name);
            user.setAmount(0);
            user.setPhone(Phone);
            user.setPassword(password);
            boolean userRegister = userService.UserRegister(user);
            if (!userRegister){
                throw new Exception("注册失败！");
            }
            return R.success(true);
        }catch (Exception e){
            return R.error("注册失败！");
        }
    }
}
