千峰商城-springboot项目搭建-68-商品评论-接口实现
一、业务层实现
1.创建接口定义方法:
productCommentsService :
public interface productCommentsService { public ResultVO listCommentsByProductId(String productId); }
2.创建实现类实现查询操作:
productCommentsServiceImpl :
@Service public class productCommentsServiceImpl implements productCommentsService { @Autowired private ProductCommentsMapper productCommentsMapper; public ResultVO listCommentsByProductId(String productId) { List<ProductCommentsVO> productCommentsVOS = productCommentsMapper.selectCommontsByProductId(productId); ResultVO resultVO = new ResultVO(ResStatus.OK, "success", productCommentsVOS); return resultVO; } }
二、控制层实现
ProductController :
@RestController @CrossOrigin @RequestMapping("/product") @Api(value = "提供商品信息相关的接口",tags = "商品管理") public class ProductController { @Autowired private ProductService productService; @Autowired private ProductCommentsService productCommentsService; @ApiOperation("商品基本信息查询接口") @GetMapping("/detail-info/{pid}") public ResultVO getProductBasicInfo(@PathVariable("pid") String pid){ return productService.getProductBasicInfo(pid); } @ApiOperation("商品参数信息查询接口") @GetMapping("/detail-params/{pid}") public ResultVO getProductParams(@PathVariable("pid") String pid){ return productService.getProductParamsById(pid); } @ApiOperation("商品评论信息查询接口") @GetMapping("/detail-commonts/{pid}") public ResultVO getProductCommonts(@PathVariable("pid") String pid){ return productCommentsService.listCommentsByProductId(pid); } }
