    public static void main(String[] args) {
        // 创建模板工厂和模板实例
        MustacheFactory mf = new DefaultMustacheFactory();
        Mustache mustache = mf.compile("template.mustache");

        // 准备数据
        Map<String, Object> data = new HashMap<>();
        data.put("name", "World");

        // 定义Lambda表达式
        data.put("lambda", (writer, context) -> writer.write("Hello, " + context.get("name") + "!"));

        // 渲染模板
        StringWriter writer = new StringWriter();
        mustache.execute(writer, data).flush();

        // 输出结果
        System.out.println(writer.toString());
    }
