前導：
發過程中經常會使用java將office系列文檔轉換為PDF， 一般都使用微軟提供的openoffice+jodconverter 實現轉換文檔。
openoffice既有windows版本也有linux版。不用擔心生產環境是linux系統。
1、openoffice依賴jar，以maven為例：
<dependency> <groupId>com.artofsolving</groupId> <artifactId>jodconverter</artifactId> <version>2.2.1</version> </dependency> <dependency> <groupId>org.openoffice</groupId> <artifactId>jurt</artifactId> <version>3.0.1</version> </dependency> <dependency> <groupId>org.openoffice</groupId> <artifactId>ridl</artifactId> <version>3.0.1</version> </dependency> <dependency> <groupId>org.openoffice</groupId> <artifactId>juh</artifactId> <version>3.0.1</version> </dependency> <dependency> <groupId>org.openoffice</groupId> <artifactId>unoil</artifactId> <version>3.0.1</version> </dependency> <!--jodconverter2.2.1必須依賴slf4j-jdk14必須這個版本，不然源碼中日誌會報錯，很low的一個問題--> <dependency> <groupId>org.slf4j</groupId> <artifactId>slf4j-jdk14</artifactId> <version>1.4.3</version> </dependency>
2、直接上轉換代碼，需要監聽openoffice應用程序8100端口即可。
public void convert(File sourceFile, File targetFile) { try { // 1: 打開連接OpenOfficeConnection connection = new SocketOpenOfficeConnection(8100); connection.connect(); DocumentConverter converter = new OpenOfficeDocumentConverter(connection); // 2:獲取Format DocumentFormatRegistry factory = new BasicDocumentFormatRegistry(); DocumentFormat inputDocumentFormat = factory .getFormatByFileExtension(getExtensionName(sourceFile.getAbsolutePath())); DocumentFormat outputDocumentFormat = factory .getFormatByFileExtension(getExtensionName(targetFile.getAbsolutePath())); // 3:執行轉換converter.convert(sourceFile, inputDocumentFormat, targetFile, outputDocumentFormat); } catch (ConnectException e) { log.info("文檔轉換PDF失敗"); } }3、需注意：jodconverter 在轉換2007版本以後的xxx.docx文檔會報錯，原因大家都明03後綴名xxx.doc 07以後版本xxx.docx
查看jodconverter源碼發現documentFormat不支持xxx.docx格式BasicDocumentFormatRegistry中public DocumentFormat getFormatByFileExtension(String extension)默認支持是使用doc格式

解決方法：重寫BasicDocumentFormatRegistry類中public DocumentFormat getFormatByFileExtension(String extension)方法，只要是後綴名包含doc則使用doc的documentFormat文檔格式
