JDK版本异常报错
一、错误提示
提示主要部分为标注部分
二、问题分析
java的编译环境版本太低，java 8 class file的版本是52，Java 7虚拟机只能支持到51。所以需要升级到java 8 vm才行。
一下为jdk的version对照表
Java SE 9 = 53,
Java SE 8 = 52,
Java SE 7 = 51,
Java SE 6.0 = 50,
Java SE 5.0 = 49,
JDK 1.4 = 48,
JDK 1.3 = 47,
JDK 1.2 = 46,
JDK 1.1 = 45
三、解决方法
升级jdk即可解决
1. Go to Maven Settings -> Maven -> Importing. Set the JDK for importer to 1.8
2. Go to Maven Settings -> Maven -> Runner. Set the JRE to 1.8
3. Go to File -> Project Structure -> SDKs. Make sure the JDK home path is set to 1.8
