Question

我正在使用Java和LibreOffice API，我想绘制矩形并设置它们的名称，或者在它们上面添加一些文本字段。绘图形状相对容易，但添加文本真的很难。我没有在文档和论坛中找到任何解决方案。

我正在声明形状和文字：

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);

然后我试图设置XText：

xShapeText.setString("ABC");

这就是出现问题的地方（即使在阅读文档中的说明后，我也不清楚这个例外）：

com.sun.star.lang.DisposedException 在com.sun.star.lib.uno.environments.remote.JobQueue.removeJob（JobQueue.java:210）在com.sun.star.lib.uno.environments.remote.JobQueue.enter（JobQueue.java:330）在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）在com.ericsson.stpdiagramgenerator.presentation.core.HelloTextTableShape.manipulateText（HelloTextTableShape.java:265） at com.ericsson.stpdiagramgenerator.presentation.core.HelloTextTableShape.useWriter（HelloTextTableShape.java:65）在com.ericsson.stpdiagramgenerator.presentation.core.HelloTextTableShape.useDocuments（HelloTextTableShape.java:52）在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）在com.intellij.rt.execution.application.AppMain.main（AppMain.java:147）引起：java.io.IOException：com.sun.star.io.IOException：已达到EOF - 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）在java.io.DataInputStream.readInt（DataInputStream.java:387）在com.sun.star.lib.uno.protocols.urp.urp.readBlock（urp.java:355）在com.sun.star.lib.uno.protocols.urp.urp.readMessage（urp.java:92）在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。

您的代码在我的计算机上正常运行。我在Windows上的LibreOffice 5.1.0.3中进行了测试。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);
}

要运行它，我打开了一个新的LibreOffice Draw文件，然后按下＆＃34;运行项目＆＃34;在NetBeans中。这就是结果：

看起来异常可能是由连接到文档的问题引起的。你究竟是怎么运行宏的？
