从 LibreOffice 扩展 JAVA 运行宏

Question

我正在尝试从扩展中的 java 按钮运行宏（宏在 Writer Standard.Voto.Main 中）。

这是按钮：

<dlg:button dlg:id="Bt_voto" dlg:tab-index="2" dlg:left="78" dlg:top="15" dlg:width="52" dlg:height="12" dlg:tag="B" dlg:value="Voto"><script:eventscript:event-name="on-performaction" script:macro-name="vnd.sun.star.UNO:ConfigChange" script:language="UNO"/>

我从这个类中调用方法：

public boolean callHandlerMethod(XDialog dialog, Object eventObject, String methodName)
        throws WrappedTargetException {
    if (methodName.equals(ConfigChange)) {

        try {
            String param = "";
            // String cmd =
            // "Standard.Conversion.ConvertHTMLToWord?langauge=Basic&location=application";
            String cmd = "Standard.Voto.Main?langauge=Basic&location=Document";
            System.out.println("Running macro on " + param);
            Macro macObj = new Macro();
            macObj.executeMacro(cmd, new Object[] { param });
            System.out.println("Completed?");
            onOkButtonPressed();
        } catch (Exception e) {
            System.out.println(e.toString());
            // e.printStackTrace();
        }

Macro.class 是：

class Macro {

    public Object executeMacro(String strMacroName, Object[] aParams) throws BootstrapException
    {

        String oooExecFolder = "C:/Program Files (x86)/LibreOffice 5/program";


        try {
            System.out.println("Completed1");
            XComponentContext xContext = BootstrapSocketConnector.bootstrap(oooExecFolder);
            XMultiComponentFactory xMultiComponentFactory = xContext.getServiceManager();
            XComponentLoader xcomponentloader = (XComponentLoader) UnoRuntime.queryInterface(XComponentLoader.class,xMultiComponentFactory.createInstanceWithContext("com.sun.star.frame.Desktop", xContext));
            System.out.println("Completed2");


            com.sun.star.text.XTextDocument mxDoc = openWriter(xContext);

            XScriptProviderSupplier xScriptPS = (XScriptProviderSupplier) UnoRuntime.queryInterface(XScriptProviderSupplier.class, xcomponentloader);
            XScriptProvider xScriptProvider = xScriptPS.getScriptProvider(); 
            XScript xScript = xScriptProvider.getScript("vnd.sun.star.script:"+strMacroName); 

            short[][] aOutParamIndex = new short[1][1];
            Object[][] aOutParam = new Object[1][1];

            aParams = new String[2];

            @SuppressWarnings("unused")
            Object result = xScript.invoke(aParams, aOutParamIndex, aOutParam);
            System.out.println("xScript invoke macro " + strMacroName);

        } catch (Exception e) { 
            throw new RuntimeException(e);

        }
        return oooExecFolder; 
    }

    public static com.sun.star.text.XTextDocument openWriter(com.sun.star.uno.XComponentContext xContext)
    {

        com.sun.star.frame.XComponentLoader xCLoader; 
        com.sun.star.text.XTextDocument xDoc = null; 
        com.sun.star.lang.XComponent xComp = null; 

        try { 
            // get the remote office service manager 
            com.sun.star.lang.XMultiComponentFactory xMCF = 
                xContext.getServiceManager(); 

            Object oDesktop = xMCF.createInstanceWithContext( 
                                        "com.sun.star.frame.Desktop", xContext); 

            xCLoader = (com.sun.star.frame.XComponentLoader) 
                UnoRuntime.queryInterface(com.sun.star.frame.XComponentLoader.class, 
                                          oDesktop); 
            com.sun.star.beans.PropertyValue [] szEmptyArgs = 
                new com.sun.star.beans.PropertyValue [0];
           /*
            ArrayList<PropertyValue> props = new ArrayList<PropertyValue>();
            PropertyValue p = new PropertyValue();
            p.Name = "Hidden";
            p.Value = new Boolean(true);
            props.add(p);

            PropertyValue[] properties = new PropertyValue[props.size()];
            props.toArray(properties);
            String strDoc = "private:factory/swriter";
            xComp = xCLoader.loadComponentFromURL(strDoc, "_blank", 0, properties);            
            */
            String strDoc = "private:factory/swriter"; 
            xComp = xCLoader.loadComponentFromURL(strDoc, "_blank", 0, szEmptyArgs); 
            xDoc = (com.sun.star.text.XTextDocument) 
                UnoRuntime.queryInterface(com.sun.star.text.XTextDocument.class, 
                                          xComp); 

        } catch(Exception e){  
            System.err.println(" Exception " + e); 
            e.printStackTrace(System.err); 
        }        
        return xDoc; 
    }
}

如果我运行这个类，引导程序可以工作，但它会在这一行终止：

XComponentContext xContext = BootstrapSocketConnector.bootstrap(oooExecFolder);

没有错误。你能帮帮我吗？

直接从对话框中调用 Basic 宏要容易得多。即使扩展的其余部分使用 Java，这仍然有效。请务必使用正确的Script URI。

<dlg:button dlg:id="Bt_voto" dlg:tab-index="3" dlg:left="173" dlg:top="88" dlg:width="51" dlg:height="13" dlg:value="Voto">
  <script:event script:event-name="on-performaction" script:macro-name="vnd.sun.star.script:Standard.Voto.Main?language=Basic&amp;location=application" script:language="Script"/>
</dlg:button>

但是，如果您出于其他原因确实需要使用 Java，请继续阅读。您似乎试图合并来自两个不同项目的代码：

• https://github.com/smehrbrodt/libreoffice-starter-extension
• https://github.com/kinow/bootstrapconnector

问题是有些命令应该只执行一次，每个项目都执行，导致重复。不要引导第二次。相反，将上下文存储在某处，以便在需要时将其传递给 Macro 类。

以下是对我有用的代码的相关部分。为了测试，我在 StarterProjectImpl.java 中添加了一个 main 方法。这使得可以看到错误消息。

public static void main (String [] args) {
    com.sun.star.uno.XComponentContext xContext = null;
    try {
        xContext = com.sun.star.comp.helper.Bootstrap.bootstrap();
        ActionOneDialog actionOneDialog = new ActionOneDialog(xContext);
        actionOneDialog.show();
    } catch (Exception exc) {
        exc.printStackTrace();
    }
}

public ActionOneDialog(XComponentContext xContext) {
    m_xContext = xContext;
    this.dialog = DialogHelper.createDialog("ActionOneDialog.xdl", xContext, this);
}

public boolean callHandlerMethod(XDialog dialog, Object eventObject, String methodName) throws WrappedTargetException {
    if (methodName.equals(ConfigChange)) {
        try {
            String cmd = "Standard.Voto.Main?language=Basic&location=application";
            Macro macObj = new Macro(m_xContext);
        }
    }

public Object executeMacro(String strMacroName, Object[] aParams)
{
    String oooExecFolder = "C:/Program Files (x86)/LibreOffice 5/program";
    try {
        XMultiComponentFactory xMultiComponentFactory = m_xContext.getServiceManager();
        Object oDesktop = xMultiComponentFactory.createInstanceWithContext( 
                        "com.sun.star.frame.Desktop", m_xContext); 
        XComponentLoader xcomponentloader = (com.sun.star.frame.XComponentLoader) 
            UnoRuntime.queryInterface(com.sun.star.frame.XComponentLoader.class, 
                                  oDesktop); 
        com.sun.star.text.XTextDocument mxDoc = openWriter(m_xContext);

        XScriptProviderSupplier xScriptPS = (XScriptProviderSupplier) UnoRuntime.queryInterface(
                XScriptProviderSupplier.class, mxDoc);
        XScriptProvider xScriptProvider = xScriptPS.getScriptProvider(); 
        XScript xScript = xScriptProvider.getScript("vnd.sun.star.script:"+strMacroName); 
    } catch (Exception e) { 
        e.printStackTrace();
        throw new RuntimeException(e);
    }
}

编辑：

以下是分步说明。在 LibreOffice 中，转到 Tools -> Macros -> Organize Macros -> LibreOffice Basic。在My Macros & Dialogs -> Standard -> Voto 下，粘贴以下代码：

Sub Main
    MsgBox("Hello, Voto!")
End Sub

接下来关注Get Started instructions。 展开 dialog -> ActionOneDialog.xdl 并转到 Source 选项卡。在</dlg:button>之后粘贴以下代码。

<dlg:button dlg:id="Bt_voto" dlg:tab-index="4" dlg:left="100" dlg:top="88" dlg:width="51" dlg:height="13" dlg:value="Voto">
  <script:event script:event-name="on-performaction" script:macro-name="vnd.sun.star.script:Standard.Voto.Main?language=Basic&amp;location=application" script:language="Script"/>
</dlg:button>

现在运行它来添加扩展。最后在 LibreOffice 中，转到 Starter Project -> Action One 并单击 Voto。结果应该是这样的：

根据我的经验，无法从对话框事件处理程序中插入字段。而是等到对话框执行完毕后再插入字段。

对于这个项目，应该可以修改 ActionOneDialog.java 中的show()。在命令 dialog.execute() 之后，编写 Java 代码以使用调度程序插入字段。
