Please check whether there is any in the target file after packaging   Application profile

  If not, add the following code to the POM file

         <resources>
            <resource>
                <directory>src/main/java</directory>
                <includes>
                    <include>mapper/*.xml</include>
                </includes>
                <filtering>true</filtering>
            </resource>
            <resource>
                <directory>src/main/resources</directory>
            </resource>
        </resources>
