解决maven项目java读取resource目录下的文件(excel文件)乱码

maven会对resource下的配置文件进行一次filter并重新编码, 就是这个过程导致了excel文件乱码, 只要将指定配置文件配置为不需要进行filter重编码即可:

<build>
...
        <resources>
            <resource>
                <directory>src/main/resources</directory>
                <excludes>
                    <exclude>config/**</exclude>
                </excludes>
                <filtering>true</filtering>
            </resource>
            <resource>
                <directory>src/main/java</directory>
                <filtering>false</filtering>
                <includes>
                    <include>**/mapper/*.xml</include>
                    <include>**/*.xls</include>
                </includes>
            </resource>
        </resources>
...
</build>
