mybatis批量刪除資料，將需要刪除的資料id存放到list中，將list作為引數傳遞，具體程式碼如下:

1、在mapper層中建立deleteAudioAudioFiles(@Param(“ids”)List ids) 方法，返回刪除的資料條數

	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);     //批量刪除資料
	}

2、mybatis的xml檔案中的delete語句如下:

	<?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>
