jdk17不在支持javascript解决方法

jdk在11开始就标注要取消NashornscriptEngineFactory类。在17中删除。给出的理由是因为jdk中维护不方便。所以我们可以在maven中找到对应的开发包。

    // https://mvnrepository.com/artifact/org.openjdk.nashorn/nashorn-core
    implementation group: 'org.openjdk.nashorn', name: 'nashorn-core', version: '15.3'

引入后代码加入

    scriptEngineManager scriptEngineManager = new scriptEngineManager();
        scriptEngineManager.registerEngineName("test",new NashornscriptEngineFactory());
        scriptEngine engine = scriptEngineManager.getEngineByName("js");
