在Java中运行Javascript
Java SE 6 开始支持各种脚本语言如PHP、Ruby、JavaScript、Python等。Java 6 默认支持执行Javascript，它是通过js引擎Mozilla Rhino来实现的。如：
ScriptEngineManager manager = new ScriptEngineManager();ScriptEngine engine = manager.getEngineByName("js");System.out.println(engine.getClass());engine.put("age", 21);engine.eval("if (age >= 18){ " + " print('Old enough to vote!'); " + "} else {" + " print ('Back to school!');" + "}"); ScriptEngineManager manager = new ScriptEngineManager(); ScriptEngine engine = manager.getEngineByName("js"); engine.put("a", 1); engine.put("b", 5); Bindings bindings = engine.getBindings(ScriptContext.ENGINE_SCOPE); Object a = bindings.get("a"); Object b = bindings.get("b"); System.out.println("a = " + a); System.out.println("b = " + b); Object result = engine.eval("c = a + b;"); System.out.println("a + b = " + result);
