在 java Spring 引导应用程序中执行 Kotlin 脚本

Question

我正在尝试在我的 java spring 引导应用程序中执行上面的 kotlin 脚本。

public class ScriptExectuorServImpl {

    public void execute() throws ScriptException {

    ScriptEngineManager factory = new ScriptEngineManager();
    ScriptEngine engine = factory.getEngineByExtension("kts");
    engine.eval(("println('OK')"));

    }

}

我的 gradle 依赖项是

plugins {
    id 'org.springframework.boot' version '2.2.6.RELEASE'
    id 'io.spring.dependency-management' version '1.0.9.RELEASE'
    id 'java'
}

repositories {
    mavenCentral()
}

dependencies {
    implementation 'org.springframework.boot:spring-boot-starter-web'
    runtime 'org.jetbrains.kotlin:kotlin-script-util'
    runtime 'org.jetbrains.kotlin:kotlin-compiler-embeddable'
    runtime 'org.jetbrains.kotlin:kotlin-scripting-compiler-embeddable'
}

我遇到以下错误

我在resourcs/META-INF/services/javax.script.ScriptEngineFactory

下添加了org.jetbrains.kotlin.script.jsr223.KotlinJsr223JvmLocalScriptEngineFactory

我通过为库添加 kotlin 版本修复了这个错误。

rootProject.kotlinVersion=1.3.72

启动我的 spring 引导应用程序所需的最终依赖项列表是

dependencies {
    implementation 'org.springframework.boot:spring-boot-starter-web'
    implementation "org.jetbrains.kotlin:kotlin-stdlib-jdk8:${rootProject.kotlinVersion}"
    implementation "org.jetbrains.kotlin:kotlin-script-runtime:${rootProject.kotlinVersion}"
    implementation "org.jetbrains.kotlin:kotlin-script-util:${rootProject.kotlinVersion}"
    implementation "org.jetbrains.kotlin:kotlin-compiler-embeddable:${rootProject.kotlinVersion}"
    implementation "org.jetbrains.kotlin:kotlin-scripting-compiler-embeddable:${rootProject.kotlinVersion}"
    implementation "org.jetbrains.kotlin:kotlin-scripting-jvm-host-embeddable:${rootProject.kotlinVersion}"
    implementation "org.jetbrains.kotlin:kotlin-scripting-jvm-host:${rootProject.kotlinVersion}"
    implementation "org.jetbrains.kotlin:kotlin-scripting-jvm:${rootProject.kotlinVersion}"
    implementation "org.jetbrains.kotlin:kotlin-scripting-jsr223-embeddable:${rootProject.kotlinVersion}"
    implementation "org.jetbrains.kotlin:kotlin-scripting-jsr223:${rootProject.kotlinVersion}"
    testImplementation("org.springframework.boot:spring-boot-starter-test")
}
