基本上我试图将一个
javaScript函数传递给一个
Java方法,作为脚本的回调.
我可以这样做 – 但是我收到的对象是一个sun.org.mozilla.javascript.internal.InterpretedFunction,我没有看到一种方法来调用它.
有任何想法吗？
这是我到目前为止
var someNumber = 0;
function start() {
// log is just an log4j instance added to the Bindings
log.info("started....");
someNumber = 20;
// Test is a unit test object with this method on it (taking Object as a param).
test.callFromRhino(junk);
}
function junk() {
log.info("called back " + someNumber);
}
解决方法
实现界面：
import javax.script.*;
public class CallBack {
public void invoke(Runnable runnable) {
runnable.run();
}
public static void main(String[] args) throws ScriptException {
ScriptEngine js = new ScriptEngineManager().getEngineByExtension("js");
js.getContext().setAttribute("callBack",new CallBack(),ScriptContext.ENGINE_SCOPE);
js.eval("var impl = { run: function () { print('Hello,World!'); } };\n"
+ "var runnable = new java.lang.Runnable(impl);\n"
+ "callBack.invoke(runnable);\n");
}
}
