Maven警告解决：Using platform encoding (UTF-8 actually) to copy filtered resources, i.e. build is platfor

在pom.xml文件中增加如下代码即可解决。

<properties>
        <maven.compiler.source>8</maven.compiler.source>
        <maven.compiler.target>8</maven.compiler.target>
        <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
</properties>
