Maven项目编译后classes文件中没有.xml问题

Posted 2020-09-20 何事西风悲画扇

在做spring＋mybatiss时，自动扫描都配置正确了，却在运行时出现了如下错误。后来查看target/classes/.../dao/文件夹下，发现只有mapper的class文件，而没有xml文件，将对应的xml文件放到这个文件夹下运行就不会出现下面的错误。说明出现这个错误的原因是maven编译时没有将xml文件放进去。

解决方法：

在pom.xml中添加如下代码：

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