Question

ibatis dao是用abator自动生成的代码，如果用到了Example实体带where条件就会出错

运行代码如下，我确保参数值是有的，始终不明白为什么，请大家帮帮忙 谢谢
List<String> idList = new ArrayList<String>();
idList = Arrays.asList(typeString);
//设置要修改的id
AreaEntityExample example = new AreaEntityExample();
example.createCriteria().andIdIn(idList);
areaDaoGenerate.updateByExampleSelective(areaEntity, example);

就是使用AreaEntityExample 就出错
不过这是自动生成的，我把注解掉就不会有错，这个问题已经困我2天了，谢谢大家帮帮忙

我用的全都是自动生成的对象，如果不使用AreaEntityExample 对象就行

Answer 1

你把那个带where的条件查询语句贴上来看看！

Answer 2

这样看只能猜,是不是你的对象和语句中少了一个字段?
