基于spring boot的校园商铺管理系统

校园商铺管理系统是一个用于管理学校商铺运营的系统，主要涉及商铺的申请、审批、管理和监管等功能。以下是一个简化版的Spring Boot商铺管理系统的核心代码示例：

// 商铺实体类
@Entity
public class Stall {
    @Id
    private Long id;
    private String name;
    private String location;
    // 省略其他属性、getter和setter
}
 
// 商铺服务接口
public interface StallService {
    List<Stall> findAll();
    Stall findById(Long id);
    void createStall(Stall stall);
    void updateStall(Stall stall);
    void deleteStall(Long id);
}
 
// 商铺服务实现类
@Service
public class StallServiceImpl implements StallService {
    @Autowired
    private StallRepository stallRepository;
 
    @Override
    public List<Stall> findAll() {
        return stallRepository.findAll();
    }
 
    @Override
    public Stall findById(Long id) {
        return stallRepository.findById(id).orElse(null);
    }
 
    @Override
    public void createStall(Stall stall) {
        stallRepository.save(stall);
    }
 
    @Override
    public void updateStall(Stall stall) {
        stallRepository.save(stall);
    }
 
    @Override
    public void deleteStall(Long id) {
        stallRepository.deleteById(id);
    }
}
 
// 商铺控制器
@RestController
@RequestMapping("/stalls")
public class StallController {
    @Autowired
    private StallService stallService;
 
    @GetMapping
    public ResponseEntity<List<Stall>> getAllStalls() {
        return ResponseEntity.ok(stallService.findAll());
    }
 
    @GetMapping("/{id}")
    public ResponseEntity<Stall> getStallById(@PathVariable Long id) {
        Stall stall = stallService.findById(id);
        if (stall == null) {
            return ResponseEntity.notFound().build();
        }
        return ResponseEntity.ok(stall);
    }
 
    @PostMapping
    public ResponseEntity<Stall> createStall(@RequestBody Stall stall) {
        stallService.createStall(stall);
        return ResponseEntity.status(HttpStatus.CREATED).body(stall);
    }
 
    @PutMapping("/{id}")
    public ResponseEntity<Stall> updateStall(@PathVariable Long id, @RequestBody Stall stall) {
        stall.setId(id);
        stallService.updateStall(stall);
        return ResponseEntity.ok(stall);
    }
 
    @DeleteMapping("/{id}")
    public ResponseEntity<?> deleteStall(@PathVariable Long id) {
        stallService.deleteStall(id);
        return ResponseEntity.noContent().build();
    }
}

这个示例展示了如何使用Spring Boot创建一个简单的RESTful API来管理学校商铺信息。实体类Stall用于定义商铺的属性，服务接口StallService和实现类\`StallSer
