mybatis配置mapper-locations坑

mybatis配置mapper-locations的坑

很多时候想把xml文件与mapper类放在一起。

mapper-locations: com.demo.dao.*.xml

这么配置之后发现报错找不到xml中id

pom.xml配置这句话就可以了！！

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

mapperLocations配置失效

xml文件的目录结构：分oracle数据库的mapper.xml文件夹和瀚高数据库的mapper.xml文件夹

mybatis配置: 加载瀚高的xml文件

启动项目报错信息：
