首先mapper类定义：
public interface VideoMapper {
void deleteAllVideo(String[] ids);
}
再次是videomapper.xml中的映射管理：
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE mapper
PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN"
"mybatis-3-mapper.dtd">
<mapper namespace="com.zhiyou100.video.mapper.VideoMapper">
<delete id="deleteAllVideo" parameterType="arraylist">
delete from video
<where>
<foreach collection="array" item="id"
separator="," open="id in (" close=")">
#{id}
</foreach>
</where>
</delete>
</mapper>
service层处理：
public interface VideoService {
void deleteAllVideo(String[] ids);
}
service impl 层处理：
@Service
public class VideoServiceImpl implements VideoService{
@Autowired
VideoMapper vm;
@Override
public void deleteAllVideo(String[] ids) {
vm.deleteAllVideo(ids);
}
}
jsp页面处理：（核心关键点）
<%@page language="java"%>
<%@page contentType="text/html"%>
<%@page pageEncoding="UTF-8"%>
<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>
<%@ taglib prefix="fn" uri="http://java.sun.com/jsp/jstl/functions" %>

controller类处理：
@Controller
@RequestMapping("/admin/video")
public class AdminVideoController {
@Autowired
VideoService vs;
@Autowired
SpeakerService ss;
@Autowired
CourseService cs;
//批量删除视频
@RequestMapping("/deleteAll")
public String deleteAll(String[] ids,Model md){
if(ids==null){
return "forward:/admin/video/listVideo.action";
}
vs.deleteAllVideo(ids);
return "forward:/admin/video/listVideo.action";
}
}
