Conmi的正确答案——JDK17运行js（使用Nashorn，非Graal.js）

jdk版本：17
Nashorn版本：15.4

Maven仓库地址：https://mvnrepository.com/artifact/org.openjdk.nashorn/nashorn-core

pom.xml中追加：

 <!-- https://mvnrepository.com/artifact/org.openjdk.nashorn/nashorn-core -->
<dependency>
    <groupId>org.openjdk.nashorn</groupId>
    <artifactId>nashorn-core</artifactId>
    <version>15.4</version>
</dependency>

java代码：

package com.example.js.test;

import org.springframework.boot.CommandLineRunner;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

import javax.script.ScriptEngine;
import javax.script.ScriptEngineManager;

/**
 * @author Administrator
 */
@SpringBootApplication
public class JsTestApplication implements CommandLineRunner {

    public static void main(String[] args) {
        SpringApplication.run(JsTestApplication.class, args);
    }

    /**
     * @param args
     * @throws Exception
     */
    @Override
    public void run(String... args) throws Exception {
        ScriptEngineManager manager = new ScriptEngineManager();
        ScriptEngine        nashorn = manager.getEngineByName("nashorn");
        System.out.println(nashorn.eval("1 + 1"));
    }
}
