今天用到了批量删除，主要也是动态sql在xml文件中实现

    <delete id="deleteByIds">
        delete from test where id in
            <foreach collection="ids" item="id" separator="," open="(" close=")">
                #{id}
            </foreach>
    </delete>

同时在controller层,要添加@requestParam注解

    public Result delete(@RequestParam List<Long> ids){
        testService.deleteBatch(ids);
        return Result.success();
    }
