Jav8: Java里面调用js代码

官方：[url]https://code.google.com/p/jav8/[/url]

An implementation of the Java Scripting API (JSR223) base on the Google V8 Javascript engine.

Java Specification Request (JSR) 223 helps developers integrate Java technology and scripting languages by defining a standard framework and application programming interface (API) to do the following:

Access and control Java technology-based objects from a scripting environment
Create web content with scripting languages
Embed scripting environments within Java technology-based applications
For more detail, please read the article Scripting for the Java Platform

To use the Jav8 Scripting Engine, place the file jav8-jsr223-xxx.jar to your classpath. Then you could get an instance of the engine this way:

ScriptEngineManager factory = new ScriptEngineManager();
ScriptEngine engine = factory.getEngineByName("jav8");
And you execute the script with the ScriptEngine.eval method

  try {
    engine.eval("print('Hello, world!')");
  } catch (ScriptException ex) {
      ex.printStackTrace();
  }
