Error attempting to get column 'content' from result set ？

</div>"

<select id="queryAllActivity" resultType="Activity">
        select * from campus_entertainment.activity limit 0,10;
    </select>

实体类也是封装了全部的，基本没问题的呀，还有content在mysql的类型是mediumtext，对应java的类型为string，为什么突然就查不出全部了，报错提示content有问题，但是只查一个select content是查得出来了，也不会乱码的，不知道为什么了，求解呀！

太奇怪了，我用万能的Map就可以解决了！！

<resultMap id="SomeActivityMap" type="java.util.HashMap"/>
    <select id="querySomeActivity" resultMap="SomeActivityMap">
        select * from campus_entertainment.activity limit 0,10;
    </select>

只是我想不通啊？？

Answer 1

mysql字段属性也就varchar，mediumtext和int，前两个在java里映射的字段都是VARCHAR，后面应该是INTEGER，我在实体类声明Integer和int都试过了，直接查询所有返回Activity类型的就不行，用了map，返回类型是hashmap，也都没设置啥，就可以了？？？
