Java设置全局变量
示例
//获取JavaScript引擎的实例
ScriptEngineManager manager = new ScriptEngineManager();
ScriptEngine engine = manager.getEngineByName("nashorn");
//定义一个全局变量
engine.put("textToPrint", "用Java定义的数据。");
//打印全局变量
try {
engine.eval("print(textToPrint);");
} catch (ScriptException ex) {
ex.printStackTrace();
}
//结果：
// '用Java定义的数据。' printed on standard output
