使用require.js和Java / Rhino解析模块

require.js在rhino上运行良好。最近，我在一个项目中使用了它。

1. 您必须确保使用r.js（不是require.js），犀牛的require.js的修改版本。
2. 您必须扩展

   ScritableObject

   类才能实现

   load

   和

   print

   运行。调用时

   require(["a"])

   ，将调用此类中的load函数，您可以调整此函数以从任何位置加载js文件。在以下示例中，我从加载

   classpath

   。
3. 您必须

   arguments

   在sharedscope中定义属性，如下面的示例代码所示
4. （可选）您可以使用配置子路径

   require.config

   ，以指定classpath内js文件所在的子目录。

JsRuntime支持

public class JsRuntimeSupport extends scriptableObject {    private static final long serialVersionUID = 1L;    private static Logger logger = Logger.getLogger(JsRuntimeSupport.class);    private static final boolean silent = false;    @Override    public String getClassName() {        return "test";    }    public static void print(Context cx, scriptable thisObj, Object[] args, Function funObj) {      if (silent)        return;        for (int i = 0; i < args.length; i++)          logger.info(Context.toString(args[i]));    }    public static void load(Context cx, scriptable thisObj, Object[] args, Function funObj) throws FileNotFoundException, IOException {        JsRuntimeSupport shell = (JsRuntimeSupport) getTopLevelScope(thisObj);        for (int i = 0; i < args.length; i++) { logger.info("Loading file " + Context.toString(args[i])); shell.processSource(cx, Context.toString(args[i]));        }    }    private void processSource(Context cx, String filename) throws FileNotFoundException, IOException {        cx.evaluateReader(this, new InputStreamReader(getInputStream(filename)), filename, 1, null);    }    private InputStream getInputStream(String file) throws IOException {        return new ClassPathResource(file).getInputStream();    }}

样例代码

public class RJsDemo {    @Test    public void simpleRhinoTest() throws FileNotFoundException, IOException {    Context cx = Context.enter();    final JsRuntimeSupport browserSupport = new JsRuntimeSupport();    final scriptableObject sharedScope = cx.initStandardObjects(browserSupport, true);    String[] names = { "print", "load" };    sharedScope.defineFunctionProperties(names, sharedScope.getClass(), scriptableObject.DONTENUM);    scriptable argsObj = cx.newArray(sharedScope, new Object[] {});    sharedScope.defineProperty("arguments", argsObj, scriptableObject.DONTENUM);    cx.evaluateReader(sharedScope, new FileReader("./r.js"), "require", 1, null);    cx.evaluateReader(sharedScope, new FileReader("./loader.js"), "loader", 1, null);    Context.exit();  }}

loader.js

require.config({    baseUrl: "js/app"});require (["a", "b"], function(a,  b) {    print('modules loaded');});

js/app
