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

2023-09-20 07:04:05 215

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。

publicvoidconvert(FilesourceFile,FiletargetFile){

try{
//1:打开连接
OpenOfficeConnectionconnection=newSocketOpenOfficeConnection(8100);
connection.connect();

DocumentConverterconverter=newOpenOfficeDocumentConverter(connection);
//2:获取Format
DocumentFormatRegistryfactory=newBasicDocumentFormatRegistry();
DocumentFormatinputDocumentFormat=factory
.getFormatByFileExtension(getExtensionName(sourceFile.getAbsolutePath()));
DocumentFormatoutputDocumentFormat=factory
.getFormatByFileExtension(getExtensionName(targetFile.getAbsolutePath()));
//3:执行转换
converter.convert(sourceFile,inputDocumentFormat,targetFile,outputDocumentFormat);
}catch(ConnectExceptione){
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publicDocumentFormatgetFormatByFileExtension(Stringextension)默认支持是使用doc格式

解决方法：重写BasicDocumentFormatRegistry类中publicDocumentFormatgetFormatByFileExtension(Stringextension)方法，只要是后缀名包含doc则使用doc的documentFormat文档格式
