java使用openoffice将office系列文档转换为PDF

前导：

1. 开发过程中经常会使用java将office系列文档转换为PDF， 一般都使用微软提供的openoffice+jodconverter 实现转换文档。
2. openoffice既有windows版本也有linux版。不用担心生产环境是linux系统。
3. 关于linux系统安装openoffice软件请参照：待更新...

4. java使用SWFTools将PDF转成swf并使用flexpaper播放PDF

1、openoffice依赖jar，以maven为例：

<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必须依赖slf4j-jdk14必须这个版本，不然源码中日志会报错，很low的一个问题--><dependency><groupId>org.slf4j</groupId><artifactId>slf4j-jdk14</artifactId><version>1.4.3</version></dependency>

2、直接上转换代码，需要监听openoffice应用程序8100端口即可。

public void convert(File sourceFile, File targetFile) {try {// 1: 打开连接OpenOfficeConnection connection = new SocketOpenOfficeConnection(8100);connection.connect();DocumentConverter converter = new OpenOfficeDocumentConverter(connection);// 2:获取FormatDocumentFormatRegistry factory = new BasicDocumentFormatRegistry();DocumentFormat inputDocumentFormat = factory.getFormatByFileExtension(getExtensionName(sourceFile.getAbsolutePath()));DocumentFormat outputDocumentFormat = factory.getFormatByFileExtension(getExtensionName(targetFile.getAbsolutePath()));// 3:执行转换converter.convert(sourceFile, inputDocumentFormat, targetFile, outputDocumentFormat);} catch (ConnectException e) {log.info("文档转换PDF失败");}}

3、需注意：jodconverter 在转换2007版本以后的xxx.docx文档会报错，原因大家都明03后缀名xxx.doc  07以后版本xxx.docx

查看jodconverter源码发现documentFormat不支持xxx.docx格式BasicDocumentFormatRegistry中public DocumentFormat getFormatByFileExtension(String extension)默认支持是使用doc格式

 解决方法：重写BasicDocumentFormatRegistry类中public DocumentFormat getFormatByFileExtension(String extension)方法，只要是后缀名包含doc则使用doc的documentFormat文档格式
