java调用openoffice将office系列文档转换为PDF的示例方

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

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:

<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> 

金冠53777,2、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
