访问Java Maps&在Rhino中列为JavaScript物件 [英] Accessing java Maps & Lists as JavaScript Objects in Rhino

问题描述

是否可以在Rhino中以JavaScript对象的形式访问Java映射和列表?

Is there a way to access Java Maps and Lists as JavaScript Objects in Rhino?

我有一个Map，它仅包含其他映射以及基元和字符串列表，我想将其传递给Rhino脚本并对其进行处理，然后将修改后的对象返回给Java-但由于它们是java.util.Map和java.util.List对象，我不能使用标准的JavaScript关联数组语法. 即:fooMap.get("keyName")将起作用，但fooMap.keyName和fooMap["keyName"]将不起作用.

I have a Map which contains only other maps and lists of primitives and Strings, I'd like to pass this to a Rhino script and do stuff to it, and return the modified object back out to Java - but since they are java.util.Map and java.util.List Objects, I can't use standard JavaScript associative array syntax. ie: fooMap.get("keyName") will work, but fooMap.keyName and fooMap["keyName"] will not.

我不知道是否有特定于Rhino的方式来执行此操作，或者是否有某些转换/广播实用程序会有所帮助. Commons BeanUtils是不够的，因为要将Map转换为bean(可以通过关联数组语法进行访问)，必须首先创建一个包含所有命名的mutators/accessor的类.我不会在运行时知道对象的结构.

I don't know if there is a Rhino-specific way to do this, or if there is some conversion/cast utility that will help. Commons BeanUtils is not sufficient, because to convert a Map to a bean (which can be accessed via associative array syntax), you must first create a class which has all of the named mutators/accessors. I won't know the structure of the object at runtime.

推荐答案

看看RingoJS.它具有方便的包装，用于Rhino的列表和地图，例如这个

Take a look at RingoJS. It has convenient wrappers for list and map for Rhino such as this one
