org.apache.ibatis.binding.BindingException: Invalid bound statement (not found): com.qingge.springbo

问题

笔者开发项目，使用SpringBoot+Mybatis技术架构，启动控制台报错

org.apache.ibatis.binding.BindingException: Invalid bound statement (not found): com.qingge.springboot.mapper.WheatMapper.findPage

详细问题

Mapper层核心代码

public interface WheatMapper extends BaseMapper<Wheat> {

    Page<Wheat> findPage(Page<Wheat> page, @Param("wheat_name") String wheat_name);
}

XML核心代码

DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN" "http://mybatis.org/dtd/mybatis-3-mapper.dtd">
<mapper namespace="com.qingge.springboot.mapper.UserMapper">

    <resultMap id="pageWheat" type="com.qingge.springboot.entity.Wheat">
        <id column="wheat_id" property="wheat_id" />
        <result column="wheat_name" property="wheat_name" />
        
    resultMap>


    <select id="findPage" resultMap="pageWheat">
        select *
        from wheat_growth_data
        <where>
            <if test="wheat_name != null and wheat_name != ''">
                and wheat_growth_data.wheat_name like concat('%', #{wheat_name} ,'%')
            if>
        where>
    select>

Closing non transactional SqlSession [org.apache.ibatis.session.defaults.DefaultSqlSession@4ba20479]

解决方案

将WheatMapper.xml作用域改为WheatMapper，保证Mapper层接口与XML层实现映射关系
具体操作如下

产生原因

问题产生的原因是MyBatis在执行查询时找不到与com.qingge.springboot.mapper.WheatMapper.findPage方法对应的映射语句。

解决原因

通过将中的命名空间更改为正确的WheatMapper，确保了XML层与Mapper层的正确映射关系。
