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：

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版本以后的xxx.docx文檔會報錯，原因大家都明03后綴名xxx.doc 07以后版本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
BasicDocumentFormatRegistry類源碼

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