The mapper file created by using the Maven project mybatis to operate the database is not put under the resource resource file. The following error occurs during compilation

org.apache.ibatis.exceptions.PersistenceException: 
### Error building SqlSession.
### The error may exist in com\atguigu\dao\StudentDao.xml
### Cause: org.apache.ibatis.builder.BuilderException: Error parsing SQL Mapper Configuration. Cause: java.io.IOException: Could not find resource com\atguigu\dao\StudentDao.xml

This is because the dao.xml file under the mapper file can not find the statement file to operate the database during compilation. There are two solutions to the problem.
the first one is to put the file to store the database statement under the resource file. Remember to modify the mybatis main configuration file

 	 <mappers>
        <mapper resource="com\zixi\dao\StudentDao.xml"/>
    </mappers>

    <!--    Modify your path directly to the following-->

    <mappers>
    <mapper resource="StudentDao.xml"/>
</mappers>
    

If you don’t want to modify and copy, you can directly add the Blid tag under the Maven configuration file and add the following content

  <build>
<!--        To solve the problem of writing sql statements in main.com.**. file, but when compiling, the xmlsql file error does not appear in out-->
        <resources>
            <resources>
                <directory>src/main/java</directory><! --directory where -->
                <includes><! --Includes directories where .properties, .xml files are scanned -->
                    <include>**/*.properties</include>
                    <include>**/*.xml</include>
                </includes>
                <filtering>false</filtering>
            </resource>
        </resources>
    </build>

This is my own practice problems, the above content can only be used as a reference, hope to be useful to you. thank you
