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

批量删除你要传一个list
通过mybatis 的动态sql 拼接

<delete id="batchDelete" parameterType="java.util.List">
    delete from tm_user where user_id in (
    values
    <foreach collection="instances" item="item" index="index" separator=",">
        #{item.userId}
    </foreach>
    )
</delete>

批量新增差不多
<insert id="batchInsert" parameterType="java.util.List">
    insert into tm_e_coupon_instance(e_coupon_id,batch_no)
    values
    <foreach collection="instances" item="item" index="index" separator=",">
        (#{item.eCouponId},#{item.batchNo})
    </foreach>

</insert>

mybatisPlus批量删除或者是插入都是通过service来调用的，而不是mapper, userService.insertBatch(List entityList),
userService.deleteBatchIds(Collection<? extends Serializable> idList)
