本文章介绍一个基于java的简单酒店数据管理系统项目介绍
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。

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);
}
}
