org.apache.ibatis.reflection.ReflectionException: There is no getter for property named 'list' in 'c
报了这个错。今天一直都在该这个方法以及优化
我的是目的是:在我的dao中根据一个对象字段进行查询,返回一个 list<对象> ,我的实体类是这样的
然后我的sql语句是这样的
主要说一下这个collection是你实体类的字段名,item 是你给该字段起的别名 ,其他的大家应知道吧。
然后我的错误是把collection 写为list 其实是错误的。应该是实体类的字段名。
注意:
Mapper.xml
<select id="getFileStrByDts" resultType="FileStr">
select * from
fileStr
where dt in
<foreach collection="dts" index="index" item="dt" open="("
separator="," close=")">
#{dt}
</foreach>
limit #{start_index},#{page_rows}
</select>
接口中:
/**
* 根据路径返回文件
*
* @param dt
* @return
*/
public List<FileStr> getFileStrByDts(Page page);
就是这个样子的
