SpringBoot整合Mybatis时mapper文件和xml文件的位置

xml文件放在resources下

1. 看下我的项目目录
   
   2.由于放在resurces下就无法扫描到xml文件，所以就需要在配置文件配置

--mapper文件位置
mybatis.mapper-locations=classpath:mapper/*.xml
或
mybatis.mapper-locations=classpath:/mapper/*.xml

xml和mapper文件放在一起

1. 我的项目目录
   
2. 但是这样会造成xml文件的打包问题
   
3. 需要.pom文件需要加入指定打包目录

<!-- 项目打包时会将java目录中的*.xml文件也进行打包 -->
    <build>
        <resources>
            <resource>
                <directory>src/main/java</directory>
                <includes>
                    <include>**/*.xml</include>
                </includes>
                <filtering>false</filtering>
            </resource>
            <resource>
                <directory>src/main/resources</directory>
            </resource>
        </resources>
    </build>

最后在整合的过程中可能会出现Springboot版本的冲突问题
