这是我的数据库

<code> tb_item_param  CREATE TABLE `tb_item_param` (                                                                        `id` bigint(20) NOT NULL AUTO_INCREMENT,                                                            `item_cat_id` bigint(20) DEFAULT NULL COMMENT '商品类目ID',                                     `param_data` text COMMENT '参数数据,格式为json格式',                                     `created` datetime DEFAULT NULL,                                                                    `updated` datetime DEFAULT NULL,                                                                    PRIMARY KEY (`id`),                                                                                 KEY `item_cat_id` (`item_cat_id`)                                                                 ) ENGINE=InnoDB AUTO_INCREMENT=28 DEFAULT CHARSET=utf8 COMMENT='商品规则参数'  </code>

我的代码

<code> public void itemParamList(int page, int rows) {        EUIDataGridResult result = new EUIDataGridResult();        TbItemParamExample example  = new TbItemParamExample();        Criteria criteria = example.createCriteria();        criteria.andIdEqualTo((long)1);        //PageHelper.startPage(page, rows);        List<tbitemparam> list = itemParamMapper.selectByExample(example);        TbItemParam tbItemParam = list.get(0);        //TbItemParam itemParam = itemParamMapper.selectByPrimaryKey((long)1);        System.out.println(tbItemParam.getParamData());</tbitemparam></code>
Copy after login

配置文件都是对的 查询出来的id什么都ok就是ParamData字段为null?TbItemParam pojo中ParamData字段是String类型,,为什么封装不进去?
pojo与mapper都是逆向工程生成的代码。。
