1. 引入maven 依赖

 <properties>
        <graalvm.version>21.1.0</graalvm.version>
    </properties>

  <!--javascript运行环境-->
        <dependency>
            <groupId>org.graalvm.sdk</groupId>
            <artifactId>graal-sdk</artifactId>
            <version>${graalvm.version}</version>
        </dependency>
        <dependency>
            <groupId>org.graalvm.js</groupId>
            <artifactId>js</artifactId>
            <version>${graalvm.version}</version>
            <scope>runtime</scope>
        </dependency>
        <dependency>
            <groupId>org.graalvm.js</groupId>
            <artifactId>js-scriptengine</artifactId>
            <version>${graalvm.version}</version>
        </dependency>

2. java 测试

public class SettingUnitService {


    ScriptEngineManager factory = new ScriptEngineManager();


    public void test1() {
        try {
            // create a JavaScript engine
            ScriptEngine engine = factory.getEngineByName("graal.js");
            Object t = engine.eval(" a=2; b=1;a>=b");
            if ((Boolean) t) {
                System.out.println(t);
            }
        } catch (ScriptException e) {
            e.printStackTrace();
        }
    }

    public static void main(String[] args) {
        SettingUnitService settingUnitService = new SettingUnitService();
        settingUnitService.test1();
    }

}
