Mybatis 批量insert

一、controller

@CrossOrigin
@RestController
@RequestMapping("/sku")
public class SkuDataController {

    @Autowired
    private SkuDataService skuDataService;

    //添加sku
    @PostMapping(value = "/add",produces = "application/json;charset=utf-8")
    public Result saveSku(@RequestBody List<SkuData>list){
        skuDataService.insert(list);
        return new Result(true, StatusCode.OK,"insert success");

二、service
public interface SkuDataService {
void insertAll(List<SkuData> list);
}

impl
@Override
public void insertAll(List<SkuData> list) {
skuDataDao.insertAll(list);
}

三、dao

@Component
@org.apache.ibatis.annotations.Mapper
public interface SkuDataDao extends Mapper<SkuData> {

    //Mybatis批量新增
    @InsertProvider(type = Provider.class, method = "insertAll")
    void insertAll(@Param(value="list")List<SkuData> skuData);

    class Provider {
        /* 批量插入 */
        public String insertAll(Map map) {
            List<SkuData> skuData = (List<SkuData>) map.get("list");
            StringBuilder sb = new StringBuilder();
            sb.append("INSERT INTO tb_sku ");
            sb.append("(id, sn, name, price, num, alertNum, image, images, weight , createTime , updateTime, spuId, categoryId, categoryName, brandName, spec, saleNum, commentNum, status, version) ");
            sb.append("VALUES ");
            MessageFormat mf = new MessageFormat(
                    "(#'{'list[{0}].id}, " +
                            "#'{'list[{0}].sn}," +
                            "#'{'list[{0}].name}," +
                            "#'{'list[{0}].price," +
                            "#'{'list[{0}].num}," +
                            "#'{'list[{0}].alertNum}," +
                            "#'{'list[{0}].image}," +
                            "#'{'list[{0}].images}," +
                            "#'{'list[{0}].weight}," +
                            "#'{'list[{0}].createTime}," +
                            "#'{'list[{0}].createTime}," +
                            "#'{'list[{0}].updateTime}," +
                            "#'{'list[{0}].spuId}," +
                            "#'{'list[{0}].categoryId}," +
                            "#'{'list[{0}].categoryName}," +
                            "#'{'list[{0}].brandName}," +
                            "#'{'list[{0}].spec}," +
                            "#'{'list[{0}].saleNum}," +
                            "#'{'list[{0}].commentNum}," +
                            "#'{'list[{0}].status}," +
                            "#'{'list[{0}].version})");

            for (int i = 0; i < skuData.size(); i++) {
                sb.append(mf.format(new Object[]{i}));
                if (i < skuData.size() - 1)
                    sb.append(",");
            }
            return sb.toString();
        }
    }
