springboot集成openoffice实现office转PDF在线预览

1、下载官网
OpenOffice 下载地址 Apache OpenOffice – Official Download

2、安装启动服务
window环境:
进入openoffice安装目录：/program/
开启服务：cmd命令

soffice -headless -accept=“socket,host=127.0.0.1,port=8100;urp;” -nofirststartwizard
Linux环境：
1. 解压缩

tar -xvzf ***.tar.gz

2.安装openoffice

cd ***/

cd RPMS/

rpm -ivh –force –nodeps *.rpm

方式一样进入安装目录启动服务

一般Linux在/opt/openoffice4下

以后台服务方式启动openoffice

/opt/openoffice4/program/soffice -headless -accept=”socket,host=127.0.0.1,port=8100;urp;” -nofirststartwizard &
3、整合Springboot
3.1 pom文件

注：jodconverter 2.2.2版本以下不支持docx等文件类型装换

3.2、yml配置文件

1. openOffice:
2. host: 127.0.0.1
3. port: 8100

   3.3OpenOfficeUtil工具类

   /**
   * @Description: office转换pdf工具类
   * @author: djq
   */
   @Component
   @Slf4j
   public class OpenOfficeUtil {
   /**
   * @Description: office转换pdf
   * @author: djq
   * @param file
   * @param outFile
   * @return
   */
   public void office2Pdf(File file, File outFile) {
   // 判断源文件是否存在
   if (!file.exists()) {
   log.error(“转换源文件不存在!”);
   throw new RuntimeException(“转换源文件不存在!”);
   }
   // 创建连接
   OpenOfficeConnection connection = null;
   try {
   // 远程连接OpenOffice服务
   log.info(“远程连接OpenOffice服务”);
   connection = new SocketOpenOfficeConnection(host, port);
   connection.connect();
   // 创建文件转换器
   DocumentConverter converter = new StreamOpenOfficeDocumentConverter(connection);
   // 开始转换
   converter.convert(file, outFile);
   if (outFile.exists()) {
   log.info(“文件转换成功”);
   } else {
   log.info(文件转换失败”);
   }
   } catch (ConnectException e) {
   e.printStackTrace();
   log.error(“OpenOffice服务启动失败”;
   } finally {
   if (connection != null) {
   connection.disconnect();
   }
   }
   }
   @Value(“${openOffice.host}”)
   private String host;
   @Value(“${openOffice.port}”)
   private int port;
   }

   3.4测试文件 日志

    写个测试类自动测试，启动测试成功

   package com.zgdz.util.controller;

   import java.io.File;

   import org.springframework.beans.factory.annotation.Autowired;
   import org.springframework.web.bind.annotation.RequestMapping;
   import org.springframework.web.bind.annotation.RestController;

   import com.zgdz.util.util.OpenOfficeUtil;

   import lombok.extern.slf4j.Slf4j;

   /**
   * @Description: test
   * @author: djq
   * @date: 2022-04-13 19:03
   */
   @RestController
   @Slf4j
   public class OpenOfficeController {
   @Autowired
   private OpenOfficeUtil openOfficeUtil;

   @RequestMapping(value = “/test”)
   public Object testOpenOffice() {
   String wordpath = “D:\\openOffice测试.docx”;
   String pdfpath = “D:\\openOffice测试.pdf”;
   openOfficeUtil.office2Pdf(new File(wordpath), new File(pdfpath));
   return true;
   }
   }
