可以使用Java中的Uno API来实现LibreOffice将Office文档转换为PDF的功能。具体实现步骤如下:
1. 首先需要安装LibreOffice,并启动LibreOffice服务。启动命令为:
```
soffice --headless --accept="socket,host=127.0.0.1,port=8100;urp;"
```
2. 在Java中使用Uno API连接LibreOffice服务,代码示例如下:
```
XComponentContext xContext = Bootstrap.bootstrap();
XMultiComponentFactory xMCF = xContext.getServiceManager();
Object oDesktop = xMCF.createInstanceWithContext("com.sun.star.frame.Desktop", xContext);
XComponentLoader xCompLoader = UnoRuntime.queryInterface(XComponentLoader.class, oDesktop);
```
3. 加载需要转换的Office文档,代码示例如下:
```
String inputUrl = "file:///path/to/input.docx";
PropertyValue[] loadProps = new PropertyValue[1];
loadProps[0] = new PropertyValue();
loadProps[0].Name = "Hidden";
loadProps[0].Value = Boolean.TRUE;
XComponent xDoc = xCompLoader.loadComponentFromURL(inputUrl, "_blank", 0, loadProps);
```
4. 将文档转换为PDF格式,代码示例如下:
```
String outputUrl = "file:///path/to/output.pdf";
PropertyValue[] convertProps = new PropertyValue[2];
convertProps[0] = new PropertyValue();
convertProps[0].Name = "FilterName";
convertProps[0].Value = "writer_pdf_Export";
convertProps[1] = new PropertyValue();
convertProps[1].Name = "Overwrite";
convertProps[1].Value = Boolean.TRUE;
XStorable xStore = UnoRuntime.queryInterface(XStorable.class, xDoc);
xStore.storeToURL(outputUrl, convertProps);
```
5. 最后需要关闭文档和LibreOffice服务,代码示例如下:
```
xDoc.dispose();
System.exit(0);
```
完整的代码示例如下:
```
import com.sun.star.comp.helper.Bootstrap;
import com.sun.star.frame.XComponentLoader;
import com.sun.star.frame.XStorable;
import com.sun.star.lang.XComponent;
import com.sun.star.lang.XMultiComponentFactory;
import com.sun.star.uno.UnoRuntime;
import com.sun.star.uno.XComponentContext;
import com.sun.star.beans.PropertyValue;
public class OfficeToPdfConverter {
public static void main(String[] args) {
try {
// Connect to LibreOffice service
XComponentContext xContext = Bootstrap.bootstrap();
XMultiComponentFactory xMCF = xContext.getServiceManager();
Object oDesktop = xMCF.createInstanceWithContext("com.sun.star.frame.Desktop", xContext);
XComponentLoader xCompLoader = UnoRuntime.queryInterface(XComponentLoader.class, oDesktop);
// Load input document
String inputUrl = "file:///path/to/input.docx";
PropertyValue[] loadProps = new PropertyValue[1];
loadProps[0] = new PropertyValue();
loadProps[0].Name = "Hidden";
loadProps[0].Value = Boolean.TRUE;
XComponent xDoc = xCompLoader.loadComponentFromURL(inputUrl, "_blank", 0, loadProps);
// Convert document to PDF
String outputUrl = "file:///path/to/output.pdf";
PropertyValue[] convertProps = new PropertyValue[2];
convertProps[0] = new PropertyValue();
convertProps[0].Name = "FilterName";
convertProps[0].Value = "writer_pdf_Export";
convertProps[1] = new PropertyValue();
convertProps[1].Name = "Overwrite";
convertProps[1].Value = Boolean.TRUE;
XStorable xStore = UnoRuntime.queryInterface(XStorable.class, xDoc);
xStore.storeToURL(outputUrl, convertProps);
// Close document and exit
xDoc.dispose();
System.exit(0);
} catch (Exception e) {
e.printStackTrace();
}
}
}
```
需要注意的是,在使用Uno API连接LibreOffice服务时,需要在classpath中加入相应的jar包。具体jar包名称和路径可以参考LibreOffice的安装目录。
