使用SpringBoot+MybatisPlus做了一个单个删除DOM，请问批量怎么删除呢

ContentCatService

//删除
    public void delete(Integer id);

public class ContentCatServiceImpl implements ContentCatService{

//删除
    public void delete(Integer id){
        List<Integer> idList = new ArrayList<>();
        idList.add(id);
        contentCatMapper.deleteBatchIds(idList);
    }

public class ContentCatController {

 //删除

    private SysResult delete(@PathVariable Integer id){
        try {
            contentCatService.delete(id);
            return SysResult.ok();
        }catch (Exception e){
            e.printStackTrace();
            return SysResult.build(201,"删除失败");
        }

请问如果改为批量删除呢
