本文深入解析商城项目的API设计与实现，涵盖属性管理、属性分组查询、产品属性配置、属性编辑保存、属性类型区分等核心功能，通过实例展示Spring Boot框架下RESTful API的开发流程。

【商城项目19】剩下的API编写

1.新增属性

特点：1.用到了org.springframework.beans.BeanUtils;

BeanUtils.copyProperties(attr,attrEntity);

2.用到了vo模型：把接受的json数据变成一个打自定义对象。

http://localhost:11000/product/attr/save

{
  "attrGroupId": 0, 
  "attrName": "像素",
  "attrType": 0, 
  "catelogId": 0, 
  "enable": 0, 
  "icon": "string", 
  "searchType": 0,
  "showDesc": 0,
  "valueSelect": "string", 
  "valueType": 0
}

{
    "msg": "success",
    "code": 0
}

@RequestMapping("/save")
//@RequiresPermissions("product:attr:save")
public R save(@RequestBody AttrVo attr) throws InvocationTargetException, IllegalAccessException {
    System.out.println(attr.getAttrName());
    attrService.saveAttr(attr);

    return R.ok();
}

    @Override
    public void saveAttr(AttrVo attr) throws InvocationTargetException, IllegalAccessException {
        AttrEntity attrEntity = new AttrEntity();
//        attrEntity.setAttrName(attr.getAttrName());
        BeanUtils.copyProperties(attr,attrEntity);
        //1、保存基本数据
        this.save(attrEntity);
        System.out.println(attrEntity.getAttrName());
        //2、保存关联关系
            AttrAttrgroupRelationEntity relationEntity = new AttrAttrgroupRelationEntity();
            relationEntity.setAttrGroupId(attr.getAttrGroupId());
            relationEntity.setAttrId(attrEntity.getAttrId());
            relationDao.insert(relationEntity);
    }

2.属性分组模糊查询

特点：用wrapper封装查询条件，使用.eq like .or

http://localhost:11000/mailproducts/attrgroup/list/170?key=不

get

{
    "msg": "success",
    "code": 0,
    "page": {
        "totalCount": 1,
        "pageSize": 10,
        "totalPage": 1,
        "currPage": 1,
        "list": [
            {
                "attrGroupId": 1,
                "attrGroupName": "不知道",
                "sort": 1,
                "descript": "七大服务",
                "icon": "群文档",
                "catelogId": 170,
                "catelogPath": null
            }
        ]
    }
}

    @RequestMapping("/list/{catelogId}")
    //@RequiresPermissions("product:attrgroup:list")
    public R list(@RequestParam Map<String, Object> params,
                  @PathVariable("catelogId") Long catelogId){
//        PageUtils page = attrGroupService.queryPage(params);

        PageUtils page = attrGroupService.queryPage(params,catelogId);

        return R.ok().put("page", page);
    }

  @Override
    public PageUtils queryPage(Map<String, Object> params, Long catelogId) {
        String key = (String) params.get("key");
        //select * from pms_attr_group where catelog_id=? and (attr_group_id=key or attr_group_name like %key%)
        QueryWrapper<AttrGroupEntity> wrapper = new QueryWrapper<AttrGroupEntity>();
        if(!StringUtils.isEmpty(key)){
            wrapper.and((obj)->{
                obj.eq("attr_group_id",key).or().like("attr_group_name",key);
            });
        }

        if( catelogId == 0){
            IPage<AttrGroupEntity> page = this.page(new Query<AttrGroupEntity>().getPage(params),
                    wrapper);
            return new PageUtils(page);
        }else {
            wrapper.eq("catelog_id",catelogId);
            IPage<AttrGroupEntity> page = this.page(new Query<AttrGroupEntity>().getPage(params),
                    wrapper);
            return new PageUtils(page);
        }
    }

3.获取某个分类的属性

http://localhost:11000/product/attr/base/listforspu/1 get

{
    "msg": "success",
    "code": 0,
    "data": [
        {
            "id": 1,
            "spuId": 1,
            "attrId": 2,
            "attrName": "尺寸",
            "attrValue": null,
            "attrSort": null,
            "quickShow": null
        },
        {
            "id": 2,
            "spuId": 1,
            "attrId": 1,
            "attrName": "像素",
            "attrValue": null,
            "attrSort": null,
            "quickShow": null
        }
    ]
}

@GetMapping("/base/listforspu/{spuId}")
public R baseAttrlistforspu(@PathVariable("spuId") Long spuId){

    List<ProductAttrValueEntity> entities = productAttrValueService.baseAttrlistforspu(spuId);

    return R.ok().put("data",entities);
}

    @Override
    public List<ProductAttrValueEntity> baseAttrlistforspu(Long spuId) {
        List<ProductAttrValueEntity> entities = this.baseMapper.selectList(new QueryWrapper<ProductAttrValueEntity>().eq("spu_id", spuId));
        return entities;
    }

4.回显属性

http://localhost:11000/product/attr/info/1 get

 @RequestMapping("/info/{attrId}")
    //@RequiresPermissions("product:attr:info")
    public R info(@PathVariable("attrId") Long attrId){
		//AttrEntity attr = attrService.getById(attrId);
        AttrRespVo respVo = attrService.getAttrInfo(attrId);

        return R.ok().put("attr", respVo);
    }

@Override
    public AttrRespVo getAttrInfo(Long attrId) {
        AttrRespVo respVo = new AttrRespVo();
        AttrEntity attrEntity = this.getById(attrId);
        BeanUtils.copyProperties(attrEntity,respVo);



            //1、设置分组信息
            AttrAttrgroupRelationEntity attrgroupRelation = relationDao.selectOne(new QueryWrapper<AttrAttrgroupRelationEntity>().eq("attr_id", attrId));
            if(attrgroupRelation!=null){
                respVo.setAttrGroupId(attrgroupRelation.getAttrGroupId());
                AttrGroupEntity attrGroupEntity = attrGroupDao.selectById(attrgroupRelation.getAttrGroupId());
                if(attrGroupEntity!=null){
                    respVo.setGroupName(attrGroupEntity.getAttrGroupName());
                }
            }


        //2、设置分类信息
        Long catelogId = attrEntity.getCatelogId();
        Long[] catelogPath = categoryService.findCatelogPath(catelogId);
        respVo.setCatelogPath(catelogPath);

        CategoryEntity categoryEntity = categoryDao.selectById(catelogId);
        if(categoryEntity!=null){
            respVo.setCatelogName(categoryEntity.getName());
        }


        return respVo;
    }

{
    "msg": "success",
    "code": 0,
    "attr": {
        "attrId": 1,
        "attrName": "像素",
        "searchType": 0,
        "valueType": null,
        "icon": "string",
        "valueSelect": "string",
        "attrType": 1,
        "enable": 1,
        "catelogId": 170,
        "showDesc": 0,
        "attrGroupId": 1,
        "catelogName": "影视",
        "groupName": "不知道",
        "catelogPath": [
            1,
            23,
            170
        ]
    }
}

5.属性修改后保存

http://localhost:11000/product/attr/update post

{
  "attrId": 1,
  "attrGroupId": 0,
  "attrName": "属性名",
  "attrType": 0, 
  "catelogId": 1,
  "enable": 0, 
  "icon": "string", 
  "searchType": 0,
  "showDesc": 0, 
  "valueSelect": "string", 
  "valueType": 0 
}

  @RequestMapping("/update")
    //@RequiresPermissions("product:attr:update")
    public R update(@RequestBody AttrVo attr){
		attrService.updateAttr(attr);

        return R.ok();
    }

AttrEntity attrEntity = new AttrEntity();
        BeanUtils.copyProperties(attr,attrEntity);
        this.updateById(attrEntity);

        if(attrEntity.getAttrType() == ProductConstant.AttrEnum.ATTR_TYPE_BASE.getCode()){
            //1、修改分组关联
            AttrAttrgroupRelationEntity relationEntity = new AttrAttrgroupRelationEntity();

            relationEntity.setAttrGroupId(attr.getAttrGroupId());
            relationEntity.setAttrId(attr.getAttrId());

            Integer count = relationDao.selectCount(new QueryWrapper<AttrAttrgroupRelationEntity>().eq("attr_id", attr.getAttrId()));
            if(count>0){

                relationDao.update(relationEntity,new UpdateWrapper<AttrAttrgroupRelationEntity>().eq("attr_id",attr.getAttrId()));

            }else{
                relationDao.insert(relationEntity);
            }
        }

6.属性区分销售属性还是分类属性

ProductConstant：

package com.ufo.common.constant;

import lombok.Data;

public class ProductConstant {


    public enum  AttrEnum{
        ATTR_TYPE_BASE(1,"基本属性"),ATTR_TYPE_SALE(0,"销售属性");
        private int code;
        private String msg;

        AttrEnum(int code,String msg){
            this.code = code;
            this.msg = msg;
        }

        public int getCode() {
            return code;
        }

        public String getMsg() {
            return msg;
        }
    }
}

   @GetMapping("/{attrType}//list/{catelogId}")
    public R baseAttrList(@RequestParam Map<String, Object> params,
                          @PathVariable("catelogId") Long catelogId,
                          @PathVariable("attrType")String type){

        PageUtils page = attrService.queryBaseAttrPage(params,catelogId,type);
        return R.ok().put("page", page);
    }

实现类：查询

 @Override
    public PageUtils queryBaseAttrPage(Map<String, Object> params, Long catelogId, String type) {
        QueryWrapper<AttrEntity> queryWrapper = new QueryWrapper<AttrEntity>();

        if(catelogId != 0){
            queryWrapper.eq("catelog_id",catelogId).eq("attr_type","base".equalsIgnoreCase(type)?1:0);
        }

        String key = (String) params.get("key");
        if(!StringUtils.isEmpty(key)){
            //attr_id  attr_name
            queryWrapper.and((wrapper)->{
                wrapper.eq("attr_id",key).or().like("attr_name",key);
            });
        }

        IPage<AttrEntity> page = this.page(
                new Query<AttrEntity>().getPage(params),
                queryWrapper
        );

        PageUtils pageUtils = new PageUtils(page);
        List<AttrEntity> records = page.getRecords();
        List<AttrRespVo> respVos = records.stream().map((attrEntity) -> {
            AttrRespVo attrRespVo = new AttrRespVo();
            BeanUtils.copyProperties(attrEntity, attrRespVo);

            //1、设置分类和分组的名字
            if("base".equalsIgnoreCase(type)){
                AttrAttrgroupRelationEntity attrId = relationDao.selectOne(new QueryWrapper<AttrAttrgroupRelationEntity>().eq("attr_id", attrEntity.getAttrId()));
                if (attrId != null && attrId.getAttrGroupId()!=null) {
                    AttrGroupEntity attrGroupEntity = attrGroupDao.selectById(attrId.getAttrGroupId());
                    attrRespVo.setGroupName(attrGroupEntity.getAttrGroupName());
                }

            }


            CategoryEntity categoryEntity = categoryDao.selectById(attrEntity.getCatelogId());
            if (categoryEntity != null) {
                attrRespVo.setCatelogName(categoryEntity.getName());
            }
            return attrRespVo;
        }).collect(Collectors.toList());

        pageUtils.setList(respVos);
        return pageUtils;
    }

实现类：更新

 @Transactional
    @Override
    public void updateAttr(AttrVo attr) {
        AttrEntity attrEntity = new AttrEntity();
        BeanUtils.copyProperties(attr,attrEntity);
        this.updateById(attrEntity);
        if(attrEntity.getAttrType() == ProductConstant.AttrEnum.ATTR_TYPE_BASE.getCode()) {
            //1、修改分组关联
            AttrAttrgroupRelationEntity relationEntity = new AttrAttrgroupRelationEntity();

            relationEntity.setAttrGroupId(attr.getAttrGroupId());
            relationEntity.setAttrId(attr.getAttrId());

            Integer count = relationDao.selectCount(new QueryWrapper<AttrAttrgroupRelationEntity>().eq("attr_id", attr.getAttrId()));
            if (count > 0) {

                relationDao.update(relationEntity, new UpdateWrapper<AttrAttrgroupRelationEntity>().eq("attr_id", attr.getAttrId()));

            } else {
                relationDao.insert(relationEntity);
            }
        }


    }

新增：

   @Override
    public void saveAttr(AttrVo attr) throws InvocationTargetException, IllegalAccessException {
        AttrEntity attrEntity = new AttrEntity();
//        attrEntity.setAttrName(attr.getAttrName());
        BeanUtils.copyProperties(attr,attrEntity);
        //1、保存基本数据
        this.save(attrEntity);
        //2、保存关联关系
        if(attr.getAttrType() == ProductConstant.AttrEnum.ATTR_TYPE_BASE.getCode() && attr.getAttrGroupId()!=null){
            AttrAttrgroupRelationEntity relationEntity = new AttrAttrgroupRelationEntity();
            relationEntity.setAttrGroupId(attr.getAttrGroupId());
            relationEntity.setAttrId(attrEntity.getAttrId());
            relationDao.insert(relationEntity);
        }

查询一个品牌有哪些分类GET
http://localhost:11000/product/categorybrandrelation/catelog/list?brandId=1
@RequestParam(“brandId”)Long brandId

给品牌新增分类：
http://localhost:11000/product/categorybrandrelation/save
{“brandId”:2,“catelogId”:5}
@RequestBody CategoryBrandRelationEntity categoryBrandRelation
