java - Rhino 报告丢失 : after property id

标签 java javascript macos mozilla rhino

我在 Mac OSX 上使用带有 envjs 1.2 的 Rhino 1.7 R4 和 JDK 1.6.0_33

如果我运行:

java -jar rhino-1.7R4.jar -opt -1

然后:

load('env.rhino-1.2.js')

然后脚本加载成功。

当我通过 RhinoTest.java 从 Java 加载相同的 JS 脚本时:

import org.apache.commons.io.IOUtils;
import org.mozilla.javascript.Context;
import org.mozilla.javascript.ContextAction;
import org.mozilla.javascript.Script;
import org.mozilla.javascript.Scriptable;

public class RhinoTest {
    static final Logger LOGGER = LoggerFactory.getLogger(RhinoTest.class);
    static private Scriptable SCRIPTABLE;
    static private List<Script> scripts;

    public static void main(String[] args) {
        ShellContextFactory cxFactory = Main.shellContextFactory;

        cxFactory.call(new ContextAction() {
            @Override
            public Object run(Context cx) {
                final Initiator initiator = new Initiator(cx).init();

                LOGGER.trace("Run script");
                try {
                    return initiator.execute();
                } finally {
                }
            }

            class Initiator {
                Initiator(Context context) {
                    this.cx = context;
                }

                Initiator init() {
                    if (SCRIPTABLE == null)
                        createScriptable();
                    initContext();
                    return this;
                }

                Object execute() {
                    return null;
                }

                void createScriptable() {

                    LOGGER.trace("init standard objects");
                    SCRIPTABLE = cx.initStandardObjects();

                    LOGGER.trace("set optimization level to -1");
                    cx.setOptimizationLevel(-1);// bypass the 64k limit // interpretive mode
                    attachJs("env.rhino-1.2.js");


                    LOGGER.trace("set optimization level to 9");
                    cx.setOptimizationLevel(9);

                }

                private void attachJs(String jsFileName) {
                    InputStream in = null;

                    if (LOGGER.isDebugEnabled()) LOGGER.debug("loading " + jsFileName);
                    try {
                        in = RhinoTest.class.getResourceAsStream(jsFileName);
                        if (in == null)
                            throw new RuntimeException("cannot find js file : " + jsFileName);

                        reader = new InputStreamReader(in);
                        if (scripts == null)
                            scripts = new ArrayList<Script>();
                        scripts.add(cx.compileReader(SCRIPTABLE, reader, jsFileName, 1, null));

                        if (LOGGER.isDebugEnabled()) LOGGER.debug("loaded " + jsFileName);
                    } catch (IOException e) {
                        throw new RuntimeException("cannot load js file : " + jsFileName, e);
                    } finally {
                        IOUtils.closeQuietly(in);
                        IOUtils.closeQuietly(reader);
                    }
                }

                void initContext() {
                    LOGGER.trace("set optimization level to -1");
                    cx.setOptimizationLevel(-1);// bypass the 64k limit // interpretive mode

                    for (Script s : scripts) {
                        s.exec(cx, SCRIPTABLE);
                    }

                }

                private final Context cx;
            }
        });


    }
}

请帮忙

最佳答案

弗拉基米尔，

你是对的，这是一个版本问题。

事实证明，我导入的蜡染库包含另一个版本的 rhino。

通过从我的项目中针对每个 batik 依赖项排除 batik-js，这个问题就消失了。
