    @ResponseBody
    public List queryList(AdContent adContent,PageParam pageParam) {
        pageParam.setPageNum(1);
        pageParam.setPageSize(2);
        PageInfo<AdContent> queryListWithPage = adContentService.queryListWithPage(adContent, pageParam);

异常:java.sql.SQLException: Value '0000-00-00' can not be represented as java.sql.Timestamp

数据库字段:
`createDate` datetime NOT NULL DEFAULT '0000-00-00 00:00:00' COMMENT '建立时间',
`updateDate` datetime NOT NULL DEFAULT '0000-00-00 00:00:00' COMMENT '更新时间',

错误分析:
Datetimes with all-zero components (0000-00-00 ...) — These values can not be represented
关于全部Datetime类型由0组成的数据，这些值不能在java中被可靠的表示


解决方式:
设置为convertToNull，用NULL值来代替这个日期类型
