probably due to a new Java class file version that isn’t supported yet

1. 错误提示

[E:\Code\git\xxx.class]; nested exception is org.springframework.core.NestedIOException:

2. Spring版本对应JDK版本

1.检查一下Spring版本和JDK 版本
Spring Framework 5.3.x: JDK 8-17 (expected)
Spring Framework 5.2.x: JDK 8-15 (expected)
Spring Framework 5.1.x: JDK 8-12
Spring Framework 5.0.x: JDK 8-10
Spring Framework 4.3.x: JDK 6-8
官网地址:
https://github.com/spring-projects/spring-framework/wiki/Spring-Framework-Versions

经过检查是JDK1.8 不兼容Spring Framework 3.2.x

3. IDEA修改项目JDK版本

1.7JDK下载地址: https://www.oracle.com/java/technologies/javase/javase7-archive-downloads.html#jdk-7u80-oth-JPR

选择JDK版本

替换Project JDK版本

修改Modules 语法级别

设置源文件路径, 编辑代码时会显示源文件形式

设置输出路径

设置JDK版本

4.Tomcat 对应JDK版本
