最近做项目时遇到一个很奇葩的现象，项目是 Spring + SpringMVC + Mybatis

<update id="batchUpdate" parameterType="java.util.List">
  <foreach collection="list" item="item" index="index">
    update kpxt_xtsz_spbm
    set sl = #{item.slpledit,jdbcType=VARCHAR}
    where del_flag=0 and id= #{item.id,jdbcType=VARCHAR};
  </foreach>
</update>

int batchUpdate(List list);

public int updateAllspbm(String slpledit,String data){
    int result = 0;
    String[] dataS = data.split(",");
    List list = new ArrayList();
    if(dataS.length>0){
        for (int i=0;i<dataS.length;i++){
            Map map  = new HashMap();
            map.put("id",dataS[i]);
            map.put("slpledit",slpledit);
            list.add(map);
        }
    }
    result = spbmMapper.batchUpdate(list);
    return result;
}

运行时报错如下：

check the manual that corresponds to your MySQL server version for the right syntax to use near‘update kpxt_xtsz_spbm set sl =？ where id=?’

找了很久发现jdbc.properties的url中少了配置

加上 &allowMultiQueries=true 就可以批量执行语句了
