Rhino转换java。lang.String到JavaScript字符串

Question

Context.javaToJS似乎只是通过了java。朗，绳子直穿

我正在对JavaScript进行沙盒处理（根据http://codeutopia.net/blog/2009/01/02/sandboxing-rhino-in-java/），因此java.lang.String在JavaScript中不可用，除非我在ClassShutter上打孔（我宁愿不这样做）

我是不是漏掉了什么明显的东西

Answer 1

试试这个：

ScriptEngineManager factory = new ScriptEngineManager();
ScriptEngine engine = factory.getEngineByName("JavaScript");
ScriptContext context = engine.getContext();
context.setAttribute("jsString", "I am Java String", ScriptContext.ENGINE_SCOPE);
context.setAttribute("jsBoolean", true, ScriptContext.ENGINE_SCOPE);
context.setAttribute("jsNumber",  123456, ScriptContext.ENGINE_SCOPE);
engine.eval("function getValueAndType(obj){return obj + ' - ' + typeof obj;}");
Assert.assertEquals("Something wen wrong", "I am Java String - string", engine.eval("getValueAndType(jsString)"));
Assert.assertEquals("Something wen wrong", "true - boolean", engine.eval("getValueAndType(jsBoolean)"));
Assert.assertEquals("Something wen wrong", "123456 - number", engine.eval("getValueAndType(jsNumber)"));
