报错如上:大概意思就是没有找到com.taotao.search.mapper.SearchItemmapper但是找到了com.taotao.search.mapper

然后顺藤摸瓜找到com.taotao.search.mapper下的SearchItemMapper.xml

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN" "http://mybatis.org/dtd/mybatis-3-mapper.dtd" >
<mapper namespace="com.taotao.search.mapper">
	<select id="getItemList" resultType="com.taotao.common.pojo.SearchItem">
		SELECT a.id,a.title,a.sell_point,a.price,b.`name` category_name,c.item_desc
		FROM tb_item a
		left join tb_item_cat b on a.cid=b.id
		left join tb_item_desc c on a.id=c.item_id
		where a.status=1
	</select>
</mapper>

namespace没有写完整,所以才导致没有找到com.taotao.search.mapper.SearchItemmapper

改正后就能跑了
