mybatis 批量删除数据

mybatis批量删除数据，将需要删除的数据id存放到list中，将list作为参数传递，具体代码如下:

1、在mapper层中创建deleteAudioAudioFiles(@Param(“ids”)List ids) 方法，返回删除的数据条数

package com.center.manager.mapper;

import java.util.List;
import org.apache.ibatis.annotations.Mapper;
import org.apache.ibatis.annotations.Param;
import com.center.manager.bean.Audio;

@Mapper
public interface AudioMapper {

    int deleteAudioAudioFiles(@Param("ids")List<String> ids);     //批量删除数据
}

2、mybatis的xml文件中的delete语句如下:

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN" "http://mybatis.org/dtd/mybatis-3-mapper.dtd" >
<mapper namespace="com.center.manager.mapper.AudioMapper">

    <delete id="deleteAudioAudioFiles">
        delete from
        t_audio
        where audio_file in
        <foreach collection="ids" item="id" open="(" separator="," close=")">
            #{id,jdbcType=VARCHAR}
        </foreach>
    </delete>

</mapper>
