报错信息
A JNI error has occurred, please check your installation and try again
Exception in thread "main" java.lang.UnsupportedClassVersionError: org/springframework/boot/loader/JarLauncher has been compiled by a more recent version of the Java Runtime (class file version 61.0), this version of the Java Runtime only recognizes class file versions up to 52.0
这个错误的意思是当时开发程序的人使用的JDK的版本要比你现在运行的环境上的JDK版本高。比如他是使用JDK11开发的,然后把程序打包好,你下载了他的jar包到本地运行,然后报错,可能你本地的JDK版本是低于11的,所以报错。
解决方法
安装JDK21就行。继续看文章下面的对应关系,就知道应该安装哪个版本。

JDK和编译版本对应关系
如何查看版本对应号
1、IDEAL新建java工程,JDK选择一个随便的jdk版本。
2、新建一个Test.java,内容如下:
package cn.renkai721;
public class Test {
public static void main(String[] args) {
System.out.println("welcome jdk 21");
}
}
3、直接运行。
4、找到编译后的Test.class文件。
5、使用UltraEdit编辑器打开这个Test.class文件,然后找到7-8位的16进制数字。

6、打开在线转换,将16进制的0041转换为10进制。
