使用Java和LibreOffice(UNO API)可以将docx文件转换为pdf文件。下面是实现此操作的步骤:
1. 首先,需要安装LibreOffice软件并启动它。
2. 然后,使用Java代码连接到LibreOffice的UNO API。
3. 接下来,使用UNO API打开docx文件。
4. 然后,使用UNO API将docx文件转换为pdf文件。
5. 最后,关闭docx文件和LibreOffice。
下面是一个简单的Java代码示例,演示如何使用LibreOffice(UNO API)将docx文件转换为pdf文件:
```java
import com.sun.star.beans.PropertyValue;
import com.sun.star.frame.XComponentLoader;
import com.sun.star.lang.XComponent;
import com.sun.star.uno.UnoRuntime;
import com.sun.star.uno.XComponentContext;
import com.sun.star.util.XCloseable;
public class DocxToPdfConverter {
public static void main(String[] args) {
String inputFile = "input.docx";
String outputFile = "output.pdf";
XComponentContext context = null;
XComponentLoader loader = null;
XComponent document = null;
try {
// Connect to LibreOffice UNO API
context = com.sun.star.comp.helper.Bootstrap.bootstrap();
loader = (XComponentLoader) UnoRuntime.queryInterface(XComponentLoader.class, context.getServiceManager().createInstanceWithContext("com.sun.star.frame.Desktop", context));
// Open docx file
PropertyValue[] propertyValues = new PropertyValue[1];
propertyValues[0] = new PropertyValue();
propertyValues[0].Name = "Hidden";
propertyValues[0].Value = Boolean.TRUE;
document = loader.loadComponentFromURL("file:///" + inputFile, "_blank", 0, propertyValues);
// Convert docx to pdf
PropertyValue[] convertProperties = new PropertyValue[2];
convertProperties[0] = new PropertyValue();
convertProperties[0].Name = "FilterName";
convertProperties[0].Value = "writer_pdf_Export";
convertProperties[1] = new PropertyValue();
convertProperties[1].Name = "Overwrite";
convertProperties[1].Value = Boolean.TRUE; ((com.sun.star.frame.XStorable) UnoRuntime.queryInterface(com.sun.star.frame.XStorable.class, document)).storeToURL("file:///" + outputFile, convertProperties);
// Close docx file and LibreOffice
((XCloseable) UnoRuntime.queryInterface(XCloseable.class, document)).close(true);
document.dispose();
context.getServiceManager().createInstanceWithContext("com.sun.star.bridge.UnoUrlResolver", context).queryInterface(XComponent.class).dispose();
context.dispose();
} catch (Exception e) {
e.printStackTrace();
}
}
}
