mybatis批量插入时如果List的size为0的话报错

使用mybatis的批量insert功能，但当List的size为0时，报sql语法错误！
业务逻辑代码如下，通过接口获取json数据，解析成Shooter对象，放到shooterList中，然后调用批量insert的方法。

List<Shooter> shooterList = new ArrayList<Shooter>();
        //中超
        Shooters shooters_zhongchao = ParseJSONUtility.parseShooterJSON(PathUtility.SHOOTERURL,configInfo.seasonid_zhongchao,PathUtility.APIKEY);
        for (Shooter shooter : shooters_zhongchao.getShooters()){
            shooter.setSeason(configInfo.seasonid_zhongchao);
            shooterList.add(shooter);
        }
shooterService.addShooterBatch(shooterList);        

mybatis配置文件的写法如下：

<insert id="addShooterBatch" parameterType="java.util.List">
        INSERT INTO shooter(jq,scsj,zg,playerid,name,teamid,teamname,rank,season)
        VALUES
        <foreach collection="list" item="item" index="index" open="" close="" separator=",">
            (#{item.jq},#{item.scsj},#{item.zg},#{item.playerid},#{item.name},#{item.teamid},#{item.teamname},#{item.rank},#{item.season})
        </foreach>
</insert>
