Java使用openoffice将office系列文檔轉換為PDF

前導：

開發過程中經常會使用java将office系列文檔轉換為PDF，一般都使用微軟提供的openoffice+jodconverter 實作轉換文檔。
openoffice既有windows版本也有linux版。不用擔心生産環境是linux系統。
關于linux系統安裝openoffice軟體請參照：待更新...

java使用SWFTools将PDF轉成swf并使用flexpaper播放PDF

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，不然源碼中日志會報錯，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應用程式8100端口即可。

public void convert(File sourceFile, File targetFile) {

		try {
			// 1: 打開連接配接
			OpenOfficeConnection connection = new SocketOpenOfficeConnection(8100);
			connection.connect();

			DocumentConverter converter = new OpenOfficeDocumentConverter(connection);
			// 2:擷取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字尾名xxx.doc 07以後版本xxx.docx

檢視jodconverter源碼發現documentFormat不支援xxx.docx格式BasicDocumentFormatRegistry中public DocumentFormat getFormatByFileExtension(String extension)預設支援是使用doc格式

解決方法：重寫BasicDocumentFormatRegistry類中public DocumentFormat getFormatByFileExtension(String extension)方法，隻要是字尾名包含doc則使用doc的documentFormat文檔格式
