mybatis 批量添加或更新

用于批量添加或更新计数数字，表中需要设置唯一索引，insert时出现重复键错误时就执行update，需要手工生成id

表结构：

索引：

mapper xml:

<insert id="updateBatch">
        insert into sx_count(id,room_id,time_id,video_id,week,count_date,nums)
        values
        <foreach collection="list" item="counter" index="index" separator=",">
            (#{counter.id}, #{counter.roomId},#{counter.timeId},#{counter.videoId},#{counter.week},#{counter.countDate},#{counter.nums})
        </foreach>
        on DUPLICATE KEY update
room_id=values(room_id),time_id=values(time_id),video_id=values(video_id),week=values(week),count_date=values(count_date),nums=nums+values(nums)
    </insert>      

mapper:

/**
     * 批量更新计数
     * @param list
     */
    void updateBatch(@Param("list") List<Counter> list);      

service:

/**
     * 更新计数记录
     *
     * @param list
     */
    @Override
    public void updateCount(List<Counter> list) {
        mapper.updateBatch(list);
    }      

测试：

@Test
    public void testBatch(){
        List<Counter> list=new ArrayList<>();

        SimpleDateFormat dateFormat = new SimpleDateFormat("yyyy-MM-dd");
        Date currentDate = new Date();
        try {
            currentDate = dateFormat.parse(dateFormat.format(new Date()));
        } catch (ParseException e) {
            e.printStackTrace();
        }

        DefaultIdentifierGenerator defaultIdentifierGenerator = new DefaultIdentifierGenerator();

        Counter c1 = new Counter();
        c1.setId(String.valueOf(defaultIdentifierGenerator.nextId(new Object())));
        c1.setRoomId("1490951884859432962");
        c1.setTimeId("1491605610842529793");
        c1.setVideoId("1491690768320892930");
        c1.setWeek(1);
        c1.setCountDate(currentDate);
        c1.setNums(1);
        list.add(c1);

        Counter c2 = new Counter();
        c2.setId(String.valueOf(defaultIdentifierGenerator.nextId(new Object())));
        c2.setRoomId("1490951884859432962");
        c2.setTimeId("1491605610842529793");
        c2.setVideoId("1491690768320892930");
        c2.setWeek(1);
        c2.setCountDate(currentDate);
        c2.setNums(3);
        list.add(c2);

        counterService.updateCount(list);

    }      

结果：
