项目介绍

该项目适用于初学java后，需要一个小练手的java web项目，该项目是只有一个酒店数据表，然后实现对该酒店增加，修改，删除和分页查询的小案例，虽然项目不是很复杂，但麻雀虽小但五脏俱全，适合于个人学习适用。

项目使用的技术架构

后端：java+SpringBoot + MyBatis-Plus
数据库：MySQL
前端：Vue + Element-ui + Axios
开发工具：idea或eclipse

项目实现

HotelController 定义了对酒店信息的CRUD的接口：

@RestController
@RequestMapping("hotel")
public class HotelController {

    @Autowired
    private IHotelService hotelService;

    /**
     * 通过id来查询酒店数据
     * @param id 酒店id号
     * @return
     */
    @GetMapping("/{id}")
    public Hotel queryById(@PathVariable("id") Long id){
        return hotelService.getById(id);
    }

    /**
     * 分页查询数据列表出来
     * @param page 页码
     * @param size 每页的大小
     * @return
     */
    @GetMapping("/list")
    public PageResult hotelList(
            @RequestParam(value = "page", defaultValue = "1") Integer page,
            @RequestParam(value = "size", defaultValue = "1") Integer size
    ){
        Page<Hotel> result = hotelService.page(new Page<>(page, size));
        return new PageResult(result.getTotal(), result.getRecords());
    }

    /**
     * 保存酒店信息
     * @param hotel 酒店信息实体类
     */
    @PostMapping
    public void saveHotel(@RequestBody Hotel hotel){
        hotelService.save(hotel);
    }

    /**
     * 更新酒店信息
     * @param hotel 酒店信息实体类
     */
    @PutMapping()
    public void updateById(@RequestBody Hotel hotel){
        if (hotel.getId() == null) {
            throw new InvalidParameterException("id不能为空");
        }
        hotelService.updateById(hotel);
    }

    /**
     * 通过酒店id删除酒店信息
     * @param id 酒店id号
     */
    @DeleteMapping("/{id}")
    public void deleteById(@PathVariable("id") Long id) {
        hotelService.removeById(id);
    }
}
