java调用openoffice将office系列文档转换为PDF的示例方法

前导:

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。

openoffice既有windows版本也有linux版。不用担心生产环境是linux系统。

1、openoffice依赖jar,以maven为例:

com.artofsolving

jodconverter

2.2.1

org.openoffice

jurt

3.0.1

org.openoffice

ridl

3.0.1

org.openoffice

juh

3.0.1

org.openoffice

unoil

3.0.1

org.slf4j

slf4j-jdk14

1.4.3

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Format

DocumentFormatRegistry 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

}

}

/**

* @return the DocumentFormat for this extension, or null if the extension is not mapped

*/

public DocumentFormat getFormatByFileExtension(String extension) {

if (extension == null) {

return null;

}

String lowerExtension = extension.toLowerCase();

for (Iterator it = documentFormats.iterator(); it.hasNext();) {

DocumentFormat format = (DocumentFormat) it.next();

if (format.getFileExtension().equals(lowerExtension)) {

return format;

}

}

return null;

}

public DocumentFormat getFormatByMimeType(String mimeType) {

for (Iterator it = documentFormats.iterator(); it.hasNext();) {

DocumentFormat format = (DocumentFormat) it.next();

if (format.getMimeType().equals(mimeType)) {

return format;

}

}

return null;

}

}

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
