Java LibreOffice Draw - 设置形状的文本

Question

我正在使用 Java 和 LibreOffice API，我想绘制矩形并设置它们的名称，或者在它们上面放置一些文本字段。绘制形状相对容易，但添加文本非常困难。无论是在文档中还是在论坛中，我都没有找到任何解决方案。

我声明形状和文本如下:

Object drawShape = xDrawFactory.createInstance("com.sun.star.drawing.RectangleShape");
XShape xDrawShape = UnoRuntime.queryInterface(XShape.class, drawShape);
xDrawShape.setSize(new Size(10000, 20000));
xDrawShape.setPosition(new Point(5000, 5000));
xDrawPage.add(xDrawShape);

XText xShapeText = UnoRuntime.queryInterface(XText.class, drawShape);
XPropertySet xShapeProps = UnoRuntime.queryInterface(XPropertySet.class, drawShape);

然后我尝试设置 XText:

xShapeText.setString("ABC");

这就是问题出现的地方(即使在阅读了文档的解释之后，这个异常对我来说也不清楚):

com.sun.star.lang.DisposedException at com.sun.star.lib.uno.environments.remote.JobQueue.removeJob(JobQueue.java:210) at com.sun.star.lib.uno.environments.remote.JobQueue.enter(JobQueue.java:330) at com.sun.star.lib.uno.environments.remote.JobQueue.enter(JobQueue.java:303) at com.sun.star.lib.uno.environments.remote.JavaThreadPool.enter(JavaThreadPool.java:87) at com.sun.star.lib.uno.bridges.java_remote.java_remote_bridge.sendRequest(java_remote_bridge.java:636) at com.sun.star.lib.uno.bridges.java_remote.ProxyFactory$Handler.request(ProxyFactory.java:146) at com.sun.star.lib.uno.bridges.java_remote.ProxyFactory$Handler.invoke(ProxyFactory.java:128) at com.sun.proxy.$Proxy6.setString(Unknown Source) at com.ericsson.stpdiagramgenerator.presentation.core.HelloTextTableShape.manipulateText(HelloTextTableShape.java:265) at com.ericsson.stpdiagramgenerator.presentation.core.HelloTextTableShape.useWriter(HelloTextTableShape.java:65) at com.ericsson.stpdiagramgenerator.presentation.core.HelloTextTableShape.useDocuments(HelloTextTableShape.java:52) at com.ericsson.stpdiagramgenerator.presentation.core.HelloTextTableShape.main(HelloTextTableShape.java:42) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:62) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) at java.lang.reflect.Method.invoke(Method.java:498) at com.intellij.rt.execution.application.AppMain.main(AppMain.java:147) Caused by: java.io.IOException: com.sun.star.io.IOException: EOF reached - socket,host=localhost,port=8100,localHost=localhost.localdomain,localPort=34456,peerHost=localhost,peerPort=8100 at com.sun.star.lib.uno.bridges.java_remote.XConnectionInputStream_Adapter.read(XConnectionInputStream_Adapter.java:55) at java.io.DataInputStream.readInt(DataInputStream.java:387) at com.sun.star.lib.uno.protocols.urp.urp.readBlock(urp.java:355) at com.sun.star.lib.uno.protocols.urp.urp.readMessage(urp.java:92) at com.sun.star.lib.uno.bridges.java_remote.java_remote_bridge$MessageDispatcher.run(java_remote_bridge.java:105)

也许您有另一种解决方案，可以使用 LibreOffice API 在形状上插入文本/文本框/文本字段。

你的代码在我的机器上运行良好。我在 Windows 上的 LibreOffice 5.1.0.3 中测试了它。这是我使用的代码:

com.sun.star.frame.XDesktop xDesktop = null;
// getDesktop() is from
// https://wiki.openoffice.org/wiki/API/Samples/Java/Writer/BookmarkInsertion
xDesktop = getDesktop();
com.sun.star.lang.XComponent xComponent = null;
try {
    xComponent = xDesktop.getCurrentComponent();
    XDrawPagesSupplier xDrawPagesSupplier = 
        (XDrawPagesSupplier)UnoRuntime.queryInterface(
            XDrawPagesSupplier.class, xComponent);
    Object drawPages = xDrawPagesSupplier.getDrawPages();
    XIndexAccess xIndexedDrawPages = (XIndexAccess)
        UnoRuntime.queryInterface(
        XIndexAccess.class, drawPages);
    Object drawPage = xIndexedDrawPages.getByIndex(0);
    XMultiServiceFactory xDrawFactory = 
        (XMultiServiceFactory)UnoRuntime.queryInterface(
            XMultiServiceFactory.class, xComponent);
    Object drawShape = xDrawFactory.createInstance(
        "com.sun.star.drawing.RectangleShape");
    XDrawPage xDrawPage = (XDrawPage)UnoRuntime.queryInterface(
        XDrawPage.class, drawPage);
    XShape xDrawShape = UnoRuntime.queryInterface(XShape.class, drawShape);
    xDrawShape.setSize(new Size(10000, 20000));
    xDrawShape.setPosition(new Point(5000, 5000));
    xDrawPage.add(xDrawShape);

    XText xShapeText = UnoRuntime.queryInterface(XText.class, drawShape);
    XPropertySet xShapeProps = UnoRuntime.queryInterface(
        XPropertySet.class, drawShape);
    xShapeText.setString("DEF");
} catch( Exception e) {
    e.printStackTrace(System.err);
    System.exit(1);
}

为了运行它，我打开了一个新的 LibreOffice Draw 文件，然后在 NetBeans 中按“运行项目”。结果是这样的:

看起来异常可能是由于连接到文档的问题引起的。您到底如何运行宏？
