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：

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

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
