Java使用ScriptEngine调用Javascript代码。

[Java]代码

package cn.outofmemory.common.utils;import java.io.File;import java.io.FileReader;import javax.script.Invocable;import javax.script.ScriptEngine;import javax.script.ScriptEngineManager;import javax.script.ScriptException;public class CoffeeScript {    public static ScriptEngineManager mgr = new ScriptEngineManager();    public static ScriptEngine jsEngine = mgr.getEngineByName("JavaScript");    static {        try {            jsEngine.eval(new FileReader(new File("coffee-script.js")));        } catch (Exception ex) {            ex.printStackTrace();        }    }    public static String compile(String coffeescript) throws ScriptException {        try {            Invocable invocableEngine = (Invocable) jsEngine;            String output = (String) invocableEngine.invokeFunction(                    "compile_coffee", coffeescript);            return output;        } catch (NoSuchMethodException ex) {            ex.printStackTrace();            return "";        }    }}

我们定义一个compile_coffee来包装一下js的CoffeeScript的compile方法

function compile_coffee(a){    return CoffeeScript.compile(a);}
