1.业务层实现:
CategoryServic接口:
public interface CategoryService {
public ResultVO listCategories();
}
CategoryServicImpl实现类:
@Service
public class CategoryServiceImpl implements CategoryService {
@Autowired
private CategoryMapper categoryMapper;
public ResultVO listCategories() {
List<CategoryVO> categoryVOS = categoryMapper.selectAllCategories();
ResultVO resultVO = new ResultVO(ResStatus.OK, "success", categoryVOS);
return resultVO;
}
}
2.控制层实现:
indexController中:
@RestController
@CrossOrigin
@RequestMapping("/index")
@Api(value = "提供首页数据显示所需的接口",tags = "首页管理")
public class IndexController {
@Autowired
private IndexImgService indexImgService;
@Autowired
private CategoryService categoryService;
@GetMapping("/indeximg")
@ApiOperation("首页轮播图接口")
public ResultVO listIndexImgs(){
return indexImgService.listIndexImgs();
}
@GetMapping("/category-list")
