## 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。**

## 下载地址 ##

### 官网下载 ###

## 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。
