Spring MVC Javascriptテンプレートエンジンとnunjucksの統合方法は？

Question

これはhttp://www.mkyong.com/spring-mvc/spring-mvc-mustache-js-template-example/

@Bean 
    public ScriptTemplateConfigurer configurer() { 
     ScriptTemplateConfigurer configurer = new ScriptTemplateConfigurer(); 
     configurer.setEngineName("nashorn"); 
     configurer.setScripts(
       "/static/js/nunjucks.js", "/static/js/render.js"); 
     configurer.setRenderFunction("render"); 
     return configurer; 
    } 

//render.jsファイルの内容

function render(template, model, url) { 
    return nunjucks.render(template, toJsonObject(model)); 
} 

に基づいて私のテンプレートエンジンの設定で、この例外が発生しました：私は提供することができますどのように

またはnunjucksのウィンドウをシミュレートしますか？

Answer 1

var window = {}; 

ウィンドウオブジェクトをポリフィルする必要があります。
