Java calls openoffice to convert office documents to PDF. openofficepdf

Leading:

During the release process, we often use java to convert office documents to PDF files. Generally, Microsoft openoffice + jodconverter is used to convert documents.

Openoffice is available in both windows and linux. There is no need to worry that the production environment is a linux system.

1. openoffice depends on jar. maven is used as an example:

<Dependency> <groupId> com. artofsolving </groupId> <artifactId> jodconverter </artifactId> <version> 2.2.1 </version> </dependency> <groupId> org. openoffice </groupId> <artifactId> jurt </artifactId> <version> 3.0.1 </version> </dependency> <groupId> org. openoffice </groupId> <artifactId> ridl </artifactId> <version> 3.0.1 </version> </dependency> <groupId> org. openoffice </group Id> <artifactId> juh </artifactId> <version> 3.0.1 </version> </dependency> <groupId> org. openoffice </groupId> <artifactId> unoil </artifactId> <version> 3.0.1 </version> </dependency> <! -- Jodconverter2.2.1 must depend on the slf4j-jdk14 must be this version, otherwise the log in the source code will report an error, a very low problem --> <dependency> <groupId> org. slf4j </groupId> <artifactId> slf4j-jdk14 </artifactId> <version> 1.4.3 </version> </dependency>

2. directly convert the code. You only need to listen to port 8100 of the openoffice application.

Public void convert (File sourceFile, File targetFile) {try {// 1: Open the connection OpenOfficeConnection connection = new SocketOpenOfficeConnection (8100); connection. connect (); DocumentConverter converter = new OpenOfficeDocumentConverter (connection); // 2: Get Format DocumentFormatRegistry factory = new BasicDocumentFormatRegistry (); DocumentFormat inputDocumentFormat = factory. getFormatByFileExtension (getExtensionName (sourceFile. getAbsolutePath (); DocumentFormat outputDocumentFormat = factory. getFormatByFileExtension (getExtensionName (targetFile. getAbsolutePath (); // 3: Convert to converter. convert (sourceFile, inputDocumentFormat, targetFile, outputDocumentFormat);} catch (ConnectException e) {log.info ("document conversion PDF failed ");}}

3. Note: The xxx.docxdocument behind the conversion of jodconverter in 2007133 may report an error. For example, the document "xxx.doc 07" is later than xxx.docx.

Except jodconvertersource code discovery documentformatdoes not support public DocumentFormat getFormatByFileExtension (String extension) in BasicDocumentFormatRegistry in xxx.docx format

Solution: override the public DocumentFormat getFormatByFileExtension (String extension) method in the BasicDocumentFormatRegistry class. If the extension name contains doc, use the documentFormat document format of doc.
