[英]How to use mybatis get result type as a list after select from database
[英]How to use mybatis to select image that store in mysql database
我有一堂課
public class Images{
private int id;
private byte[] img;
private String name;
}
數據庫T_image中的表(id tinyint,logo_img mediumblob,名稱varchar)
我有一個dao界面
public interface ImgDAO{
public List<byte[]> selectAllImg();
}
我想在mybatis的xml映射器中為此編寫sqlmapper
像這樣使用resultMap
<resultMap class="Images" id="imageResultMap">
<result column="logo_img" property="img" jdbcType="BLOB"/>
</resultMap>
<select id="selectAllImg" resultMap="imageResultMap">
select logo_img from T_image
</select>
