今天在IDEA上打包成jar包部署到服务器上时，遇到了一个报错，写个博客记录一下

具体如下：Exception in thread "main" java.lang.UnsupportedClassVersionError: com/atguigu/mr/wordcount/WcDriver has been compiled by a more recent version of the Java Runtime (class file version 53.0), this version of the Java Runtime only recognizes class file versions up to 52.0

解决方案：我的是服务器上的jdk版本与Windows的jdk版本不一致，Windows上的JDK版本更高。解决方法：在maven下的pom.XML配置Linux中的JDK版本就解决了。仅供参考

代码如下

<!--JDK配置  -->
<properties>
    <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
    <maven.compiler.source>8</maven.compiler.source>
    <maven.compiler.target>8</maven.compiler.target>
    <spring.version>4.0.0.RELEASE</spring.version>
</properties>
