Java JODConvert 3.0最佳实践

Java: JODConverter 3.x Getting Started

April 9th, 2009 by jeremychone

Requirements:

• OpenOffice installed and OpenOffice started (e.g., OpenOffice in the system tray on Windows)
• Java

Quick steps to test:

1. Download the latest JODConverter 3.x from google code.
2. Unzip the jar file
3. Do a quick test:
   java -jar lib/jodconverter-${version}.jar test.odt test.pdf
4. you should see something like

   C:\apps\jodconverter-3.0-beta-1>java -jar lib/jodconverter-3.0-beta-1.jar test.odt test.pdfApr 9, 2009 12:56:42 PM net.sf.jodconverter.office.OfficeProcess startINFO: starting process with acceptString 'socket,host=127.0.0.1,port=8100' andprofileDir 'C:\Users\JEREMY~1\AppData\Local\Temp\.jodconverter_socket_host-127.0.0.1_port-8100'Apr 9, 2009 12:56:42 PM net.sf.jodconverter.office.OfficeProcess startINFO: started process; pid -1Apr 9, 2009 12:56:47 PM net.sf.jodconverter.office.OfficeConnection connectINFO: connected: 'socket,host=127.0.0.1,port=8100'Apr 9, 2009 12:56:52 PM net.sf.jodconverter.office.OfficeConnection$1 disposingINFO: disconnected: 'socket,host=127.0.0.1,port=8100'Apr 9, 2009 12:56:53 PM net.sf.jodconverter.office.ManagedOfficeProcess doEnsureProcessExitedINFO: process exited with code 0

Note: As you can see it works because it assumes that OpenOffice listen to the port 8100, which happen to be the case (how lucky!).

In a Java (Server) App:

1. Copy the following .jar files in your webapp lib directory
   lib/jodconverter-3.0-beta-1.jar
   lib/juh-3.0.0.jar
   lib/jurt-3.0.0.jar
   lib/ridl-3.0.0.jar
   lib/unoil-3.0.0.jar
2. Use the following code snippet:

   OfficeManager officeManager = new ManagedProcessOfficeManager();officeManager.start();OfficeDocumentConverter converter = new OfficeDocumentConverter(officeManager);converter.convert(sourceFile,targetFile);officeManager.stop();

Best Practice (from JODConverter group)

1. OfficeManager instance can and should be shared across all
   threads. It should typically be started when your webapp starts, and
   stopped when the webapp stops. It can be e.g. a singleton, or a Spring
   bean, or other equivalent approach of your choice.
2. The OfficeDocumentConverter instance can also be shared, or you can
   create a different instance per thread. It doesn’t really matter,
   since all conversions will be delegated to the OfficeManager anyway.
