其实安装完我们发现其有好多功能，现在介绍几个重要的功能。
soffice.exe --- 类似于一个全收录功能，双击可以新建好多格式文本。
sweb.exe---类似于一个html的编辑器，可以编辑好多文件，可能与notpad++更像。
scalc.exe---类似于excel，对表格处理。
simpress.exe---类似于ppt
swriter.exe---类似于word，编辑文档(当然可以打开docx文档)
sbase.exe----对数据库进行操作，可以通过JDBC、ODBC连接数据库，没有可视化工具的时候可以用这个。
2.配置环境变量(为了我们能在任何情况下调用命令)
执行命令测试soffice
C:\Users\liqiang> LibreOffice 6.0.6.2 0c292870b25a325b5ed35f6b45599d2ea4458e77 Usage: soffice [argument...] argument - switches, switch parameters and document URIs (filenames). Using without special arguments: Opens the start center, if it is used without any arguments. {file} Tries to open the file (files) in the components suitable for them. {file} {macro:///Library.Module.MacroName} Opens the file and runs specified macros from the file. Getting help and information: --help | -h | -? Shows this help and quits. --helpwriter Opens built-in or online Help on Writer. --helpcalc Opens built-in or online Help on Calc. --helpdraw Opens built-in or online Help on Draw. --helpimpress Opens built-in or online Help on Impress. --helpbase Opens built-in or online Help on Base. --helpbasic Opens built-in or online Help on Basic scripting language. --helpmath Opens built-in or online Help on Math. --version Shows the version and quits. --nstemporarydirectory (MacOS X sandbox only) Returns path of the temporary directory for the current user and exits. Overrides all other arguments. General arguments: --quickstart[=no] Activates[Deactivates] the Quickstarter service. --nolockcheck Disables check for remote instances using one installation. --infilter={filter} Force an input filter type if possible. For example: --infilter="Calc Office Open XML" --infilter="Text (encoded):UTF8,LF,,," --pidfile={file} Store soffice.bin pid to {file}. --display {display} Sets the DISPLAY environment variable on UNIX-like platforms to the value {display} (only supported by a start script). User/programmatic interface control: --nologo Disables the splash screen at program start. --minimized Starts minimized. The splash screen is not displayed. --nodefault Starts without displaying anything except the splash screen (do not display initial window). --invisible Starts in invisible mode. Neither the start-up logo nor the initial program window will be visible. Application can be controlled, and documents and dialogs can be controlled and opened via the API. Using the parameter, the process can only be ended using the taskmanager (Windows) or the kill command (UNIX-like systems). It cannot be used in conjunction with --quickstart. --headless Starts in "headless mode" which allows using the application without GUI. This special mode can be used when the application is controlled by external clients via the API. --norestore Disables restart and file recovery after a system crash. --safe-mode Starts in a safe mode, i.e. starts temporarily with a fresh user profile and helps to restore a broken configuration. --accept={UNO-URL} Specifies an UNO-URL connect-string to create an UNO acceptor through which other programs can connect to access the API. UNO-URL is string the such kind uno:connection-type,params;protocol-name,params;ObjectName. --unaccept={UNO-URL} Closes an acceptor that was created with --accept. Use --unaccept=all to close all open acceptors. --language={lang} Uses specified language, if language is not selected yet for UI. The lang is a tag of the language in IETF language tag. Developer arguments: --terminate_after_init Exit after initialization complete (no documents loaded). --eventtesting Exit after loading documents. New document creation arguments: The arguments create an empty document of specified kind. Only one of them may be used in one command line. If filenames are specified after an argument, then it tries to open those files in the specified component. --writer Creates an empty Writer document. --calc Creates an empty Calc document. --draw Creates an empty Draw document. --impress Creates an empty Impress document. --base Creates a new database. --global Creates an empty Writer master (global) document. --math Creates an empty Math document (formula). --web Creates an empty HTML document. File open arguments: The arguments define how following filenames are treated. New treatment begins after the argument and ends at the next argument. The default treatment is to open documents for editing, and create new documents from document templates. -n Treats following files as templates for creation of new documents. -o Opens following files for editing, regardless whether they are templates or not. --pt {Printername} Prints following files to the printer {Printername}, after which those files are closed. The splash screen does not appear. If used multiple times, only last {Printername} is effective for all documents of all --pt runs. Also, --printer-name argument of --print-to-file switch interferes with {Printername}. -p Prints following files to the default printer, after which those files are closed. The splash screen does not appear. If the file name contains spaces, then it must be enclosed in quotation marks. --view Opens following files in viewer mode (read-only). --show Opens and starts the following presentation documents of each immediately. Files are closed after the showing. Files other than Impress documents are opened in default mode , regardless of previous mode. --convert-to OutputFileExtension[:OutputFilterName] [--outdir output_dir] [--convert-images-to] Batch convert files (implies --headless). If --outdir isn't specified, then current working directory is used as output_dir. If --convert-images-to is given, its parameter is taken as the target MIME format for *all* images written to the output format. If --convert-to is used more than once, the last value of OutputFileExtension [:OutputFilterName] is effective. If --outdir is used more than once, only its last value is effective. For example: --convert-to pdf *.odt --convert-to epub *.doc --convert-to pdf:writer_pdf_Export --outdir /home/user *.doc --convert-to "html:XHTML Writer File:UTF8" *.doc --convert-to "txt:Text (encoded):UTF8" *.doc --print-to-file [--printer-name printer_name] [--outdir output_dir] Batch print files to file. If --outdir is not specified, then current working directory is used as output_dir. If --printer-name or --outdir used multiple times, only last value of each is effective. Also, {Printername} of --pt switch interferes with --printer-name. --cat Dump text content of the following files to console (implies --headless). Cannot be used with --convert-to. --script-cat Dump text content of any scripts embedded in the files to console (implies --headless). Cannot be used with --convert-to. -env:<VAR>[=<VALUE>] Set a bootstrap variable. For example: to set a non-default user profile path: -env:UserInstallation=file:///tmp/test Ignored switches: -psn Ignored (MacOS X only). -Embedding Ignored (COM+ related; Windows only). --nofirststartwizard Does nothing, accepted only for backward compatibility. --protector {arg1} {arg2} Used only in unit tests and should have two arguments.
4.命令行转换pdf
转换到当前目录:
liqiang@root MINGW64 ~/Desktop/新建文件夹 (3) $ soffice --headless --convert-to pdf ./Java开发-太原科技大学-软件工程-乔利强.docx convert C:\Users\liqiang\Desktop\▒½▒▒ļ▒▒▒ (3)\Java▒▒▒▒-̫ԭ▒Ƽ▒▒▒ѧ-▒▒▒▒▒▒▒-▒▒▒▒ǿ.docx -> C:\Users\liqiang\Desktop\▒½▒▒ļ▒▒▒ (3)\Java▒▒▒▒-̫ԭ▒Ƽ▒▒▒ѧ-▒▒▒▒▒▒▒-▒▒▒▒ǿ.pdf using filter : writer_pdf_Export func=xmlSecCheckVersionExt:file=..\src\xmlsec.c:line=188:obj=unknown:subj=unknown:error=19:invalid version:mode=abi compatible;expected minor version=2;real minor version=2;expected subminor version=25;real subminor version=26 liqiang@root MINGW64 ~/Desktop/新建文件夹 (3) Java开发-太原科技大学-软件工程-乔利强.docx Java开发-太原科技大学-软件工程-乔利强.pdf
如果需要转换到指定目录可以加--outdir参数
5.java程序实现word转pdf(原理是通过cmd调用上述命令)
import java.io.IOException; import java.io.InputStream; import org.slf4j.Logger; import org.slf4j.LoggerFactory; public final class Test { private static final Logger logger = LoggerFactory.getLogger(Test.class); public static void main(String[] args) throws NullPointerException { long start = System.currentTimeMillis(); String srcPath = "C:/Users/liqiang/Desktop/ww/tt.docx", desPath = "C:/Users/liqiang/Desktop/ww"; String command = ""; String osName = System.getProperty("os.name"); if (osName.contains("Windows")) { command = "soffice --headless --convert-to pdf " + srcPath + " --outdir " + desPath; exec(command); long end = System.currentTimeMillis(); logger.debug("用时:{} ms", end - start); public static boolean exec(String command) { Process process;// Process可以控制该子进程的执行或获取该子进程的信息 try { logger.debug("exec cmd : {}", command); process = Runtime.getRuntime().exec(command);// exec()方法指示Java虚拟机创建一个子进程执行指定的可执行程序，并返回与该子进程对应的Process对象实例。 // 下面两个可以获取输入输出流 InputStream errorStream = process.getErrorStream(); InputStream inputStream = process.getInputStream(); } catch (IOException e) { logger.error(" exec {} error", command, e); return false; int exitStatus = 0; try { exitStatus = process.waitFor();// 等待子进程完成再往下执行，返回值是子线程执行完毕的返回值,返回0表示正常结束 // 第二种接受返回值的方法 int i = process.exitValue(); // 接收执行完毕的返回值 logger.debug("i----" + i); } catch (InterruptedException e) { logger.error("InterruptedException exec {}", command, e); return false; if (exitStatus != 0) { logger.error("exec cmd exitStatus {}", exitStatus); } else { logger.debug("exec cmd exitStatus {}", exitStatus); process.destroy(); // 销毁子进程 process = null; return true;另一种命令的方式为 cmd /c soffice ..... .
另外写的时候最好pdf后面跟上 :writer_pdf_Export,例如: --convert-to pdf:writer_pdf_Export 可能会在转换失败后调用过滤器重写。
2018-10-25 21:56:35 [Test]-[DEBUG] exec cmd : soffice --headless --convert-to pdf C:/Users/liqiang/Desktop/ww/tt.docx --outdir C:/Users/liqiang/Desktop/ww
2018-10-25 21:56:45 [Test]-[DEBUG] i----0
2018-10-25 21:56:45 [Test]-[DEBUG] exec cmd exitStatus 0
2018-10-25 21:56:45 [Test]-[DEBUG] 用时:9980 ms2.linux实现将word转为pdf,以centos为例
1.linux下安装libreoffice
我们安装采用yum安装，首先下载rpm包。这里需要三个包。
wget http://mirrors.ustc.edu.cn/tdf/libreoffice/stable/6.0.6/rpm/x86_64/LibreOffice_6.0.6_Linux_x86-64_rpm.tar.gz wget http://mirrors.ustc.edu.cn/tdf/libreoffice/stable/6.0.6/rpm/x86_64/LibreOffice_6.0.6_Linux_x86-64_rpm_sdk.tar.gz wget http://mirrors.ustc.edu.cn/tdf/libreoffice/stable/6.0.6/rpm/x86_64/LibreOffice_6.0.6_Linux_x86-64_rpm_langpack_zh-CN.tar.gz其实我们在windows下通过浏览器访问上面链接也是可以下载tar.gz包的，如果需要不同的版本只需要修改url上的版本号即可。比如我想下载6.0.3的我可以访问下面url:
其实好多时候我们采用wget下载的时候如果下载不下来， 我们可以先在windows下访问url下载完只会传到linux服务器，这也是一种思路。
2.上传到服务器并解压
采用 tar -xvf xxxxxx.tar.gz解压即可。解压结果如下:
[root@VM_0_12_centos libreoffice]# ll total 263748 drwxr-xr-x 4 root root 4096 Jul 28 06:07 LibreOffice_6.0.6.2_Linux_x86-64_rpm drwxr-xr-x 3 root root 4096 Jul 28 07:32 LibreOffice_6.0.6.2_Linux_x86-64_rpm_langpack_zh-CN drwxr-xr-x 3 root root 4096 Jul 28 06:27 LibreOffice_6.0.6.2_Linux_x86-64_rpm_sdk -rw-r--r-- 1 root root 798421 Oct 25 12:13 LibreOffice_6.0.6_Linux_x86-64_rpm_langpack_zh-CN.tar.gz -rw-r--r-- 1 root root 36919386 Oct 25 12:24 LibreOffice_6.0.6_Linux_x86-64_rpm_sdk.tar.gz -rw-r--r-- 1 root root 213845646 Oct 25 10:33 LibreOffice_6.0.6_Linux_x86-64_rpm.tar.gz3.采用yum localinstall *.rpm安装rpm文件
[root@VM_0_12_centos RPMS]# pwd /opt/libreoffice/LibreOffice_6.0.6.2_Linux_x86-64_rpm/RPMS [root@VM_0_12_centos RPMS]# yum localinstall *.rpmRPMS下存放的是需要安装的rpm文件，进入该文件夹下采用通配符的方式安装即可。(三个tar.gz解压后的都需要安装)
4.测试libreoffice
[root@VM_0_12_centos RPMS]# libreoffice6.0 -help Warning: -help is deprecated. Use --help instead. LibreOffice 6.0.6.2 0c292870b25a325b5ed35f6b45599d2ea4458e77 Usage: soffice [argument...] argument - switches, switch parameters and document URIs (filenames).

5.为了使用libreoffice我们创建别名
[root@VM_0_12_centos ~]# alias libreoffice='libreoffice6.0' [root@VM_0_12_centos ~]# alias alias cp='cp -i' alias egrep='egrep --color=auto' alias fgrep='fgrep --color=auto' alias grep='grep --color=auto' alias l.='ls -d .* --color=auto' alias libreoffice='libreoffice6.0' alias ll='ls -l --color=auto' alias ls='ls --color=auto'2.linux下面命令行测试word转pdf(其参数与windows下的参数大体相同)
[root@VM_0_12_centos tmpFile]# ls tt.docx [root@VM_0_12_centos tmpFile]# libreoffice6.0 --convert-to pdf:writer_pdf_Export ./tt.docx func=xmlSecCheckVersionExt:file=xmlsec.c:line=188:obj=unknown:subj=unknown:error=19:invalid version:mode=abi compatible;expected minor version=2;real minor version=2;expected subminor version=25;real subminor version=26 convert /root/tmpFile/tt.docx -> /root/tmpFile/tt.pdf using filter : writer_pdf_Export [root@VM_0_12_centos tmpFile]# ls tt.docx tt.pdf [root@VM_0_12_centos tmpFile]#我们将上面生成的pdf传回windows下面查看发现中文乱码。
3.关于word转pdf中文乱码问题的解决办法
1.查看fonts目录
[root@VM_0_12_centos tmpFile]# cat /etc/fonts/fonts.conf | grep fon <!DOCTYPE fontconfig SYSTEM "fonts.dtd"> <!-- /etc/fonts/fonts.conf file to configure system font access --> <fontconfig> problems to the fontconfig bugzilla system located at fontconfig.org Note that the normal 'make install' procedure for fontconfig is to replace any existing fonts.conf file with the new version. Place <dir>/usr/share/fonts</dir> <dir>/usr/share/X11/fonts/Type1</dir> <dir>/usr/share/X11/fonts/TTF</dir> <dir>/usr/local/share/fonts</dir> <dir prefix="xdg">fonts</dir> <dir>~/.fonts</dir> <include ignore_missing="yes">/etc/fonts/conf.d</include> <cachedir>/var/cache/fontconfig</cachedir> <cachedir prefix="xdg">fontconfig</cachedir> <cachedir>~/.fontconfig</cachedir> in fonts. All other blank chars are assumed to be broken and </fontconfig>发现上面的字体存在/usr/share/fonts目录下。
2.把Windows下的字体C:\Windows\Fonts下的宋体，即simsun.ttc上传到linux服务器并赋值到上面的字体目录下赋予读写权限
[root@VM_0_12_centos libreoffice]# ll | grep simsun.ttc -rw-r--r-- 1 root root 18214472 Oct 25 13:19 simsun.ttccp simsun.ttc /usr/share/fontscd /usr/share/fonts赋予权限(默认权限也可以，如果不可以就手动赋予权限即可)
chmod 644 simsun.ttc3.更新字体缓存
fc-cache -fv再次转换pdf发现完美解决。
4.linux下Java程序调用libreoffice转换pdf
文件的位置与输出目录通过主函数参数传递进去。
(1)先写一个简单的程序进行测试
import java.io.IOException; public class Test { public static void main(String[] args) throws NullPointerException { String filePath = args[0]; String destDir = args[1]; String osName = System.getProperty("os.name"); System.out.println(filePath); System.out.println(destDir); System.out.println(osName); String cmd = "libreoffice6.0 --convert-to pdf:writer_pdf_Export " + filePath + " --outdir " + destDir; System.out.println(cmd); try { Runtime.getRuntime().exec(cmd); } catch (IOException e) { System.err.println(e.getMessage());我们在linux下面进行编译并且运行:
[root@VM_0_12_centos tmpFile]# javac Test.java [root@VM_0_12_centos tmpFile]# java Test ./tt.docx ./ ./tt.docx Linux libreoffice6.0 --convert-to pdf:writer_pdf_Export ./tt.docx --outdir ./ [root@VM_0_12_centos tmpFile]# ls Test.class Test.java tt.docx tt.pdf(2)接下来简单的编写程序获取转换时间:(使线程等待抓换完成)
import java.io.IOException; public class Test { public static void main(String[] args) throws NullPointerException { long start = System.currentTimeMillis(); String filePath = args[0]; String destDir = args[1]; String osName = System.getProperty("os.name"); System.out.println(filePath); System.out.println(destDir); System.out.println(osName); String cmd = "libreoffice6.0 --convert-to pdf:writer_pdf_Export " + filePath + " --outdir " + destDir; System.out.println(cmd); try { Process process = Runtime.getRuntime().exec(cmd); try { // 获取返回状态 int status = process.waitFor(); // 销毁process process.destroy(); process = null; System.out.println("status -> " + status); } catch (InterruptedException e) { System.err.println(e.getMessage()); } catch (IOException e) { System.err.println(e.getMessage()); long end = System.currentTimeMillis(); System.out.println("用时:" + (end - start) + "ms");再次在linux下面编译运行:
[root@VM_0_12_centos tmpFile]# java Test ./tt.docx ./ ./tt.docx Linux libreoffice6.0 --convert-to pdf:writer_pdf_Export ./tt.docx --outdir ./ status -> 0 用时:1463ms [root@VM_0_12_centos tmpFile]# ls Test.class Test.java tt.docx tt.pdf至此完成了使用libreoffice在windows与linux下面转换pdf，这种方式感觉比较稳定。同时也学会了Runtime 调用本地程序以单线程方式运行的方法。
文中用到的所有的tar包以及字体simsun.ttc下载地址:http://qiaoliqiang.cn/fileDown/linuxlibreoffice.zip
补充:word也可以转为html，测试word转html
word内容:
补充:其实excel和ppt也可以转为pdf和html以及jpg，下面研究excel转换(只是边框被去掉，如果需要显示边框在excel中的样式需要显示边框；而且内容过长会折行，解决办法就是缩小列宽、减少列数)
原来excel内容:
soffice.exe --headless --convert-to jpg ./test.xls soffice.exe --headless --convert-to html ./test.xls soffice.exe --headless --convert-to pdf ./test.xls(1)转换后的jpg
(2)转换的html
(3)转换后的pdf
补充:直接拷贝目录遇到的问题：
今天拷贝下载好的目录使用时，发现报错缺失VCRUNTIME140.dll和MSVCP140.dll,于是拷贝另外一台电脑到缺失的电脑上就可以了。记住是C:\Windows\System32目录和C:\Windows\SysWOW64目录下对应的dll，这两个文件夹下的dll不一样，虽然文件名一样，但是大小不一样，所以要复制对应的dll。
补充；java也可以用jodconverter进行转换，我用的是jodconverter2.2版本(该工具包依赖openoffice或libreoffice插件)
依赖的jar包如下：
代码如下：
import java.io.File; import java.io.IOException; import com.artofsolving.jodconverter.DocumentConverter; import com.artofsolving.jodconverter.openoffice.connection.OpenOfficeConnection; import com.artofsolving.jodconverter.openoffice.connection.SocketOpenOfficeConnection; import com.artofsolving.jodconverter.openoffice.converter.OpenOfficeDocumentConverter; public class Office2Pdf { // 将word格式的文件转换为pdf格式 public static void WordToPDF(String startFile, String overFile) throws IOException { // 源文件目录 File inputFile = new File(startFile); if (!inputFile.exists()) { System.out.println("源文件不存在！"); return; // 输出文件目录 File outputFile = new File(overFile); if (!outputFile.getParentFile().exists()) { outputFile.getParentFile().exists(); // 调用openoffice服务线程 /** 我把openOffice下载到了 C:/Program Files (x86)/下 ,下面的写法自己修改编辑就可以 **/ String command = "D:/zdc8/lo/program/soffice.exe -headless -accept=\"socket,host=127.0.0.1,port=8300;urp;\""; Process p = Runtime.getRuntime().exec(command); // 连接openoffice服务 OpenOfficeConnection connection = new SocketOpenOfficeConnection("127.0.0.1", 8300); connection.connect(); // 转换 DocumentConverter converter = new OpenOfficeDocumentConverter(connection); converter.convert(inputFile, outputFile); // 关闭连接 connection.disconnect(); // 关闭进程 p.destroy(); public static void main(String[] args) { String start = "C:\\Users\\Administrator\\Desktop\\123.xlsx"; String over = "C:\\Users\\Administrator\\Desktop\\123.xlsx.pdf"; try { WordToPDF(start, over); } catch (IOException e) { e.printStackTrace();如果想去掉留痕，需要反编译jodconverter-2.2.2.jar,获取类OpenOfficeDocumentConverter.java，修改方法loadAndExport，如下：(加粗部分是添加的代码)
private void loadAndExport(String inputUrl, Map/* <String,Object> */ loadProperties, String outputUrl, Map/* <String,Object> */ storeProperties) throws OpenOfficeException { XComponent document; try { document = loadDocument(inputUrl, loadProperties); } catch (ErrorCodeIOException errorCodeIOException) { throw new OpenOfficeException( "conversion failed: could not load input document; OOo errorCode: " + errorCodeIOException.ErrCode, errorCodeIOException); } catch (Exception otherException) { throw new OpenOfficeException("conversion failed: could not load input document", otherException); if (document == null) { throw new OpenOfficeException("conversion failed: could not load input document"); XPropertySet mxDocProps = (XPropertySet) UnoRuntime.queryInterface(XPropertySet.class, document); try { mxDocProps.setPropertyValue("RedlineDisplayType", RedlineDisplayType.NONE); } catch (Exception e) { throw new OpenOfficeException("dispose RedlineDisplay failed", e); refreshDocument(document); try { storeDocument(document, outputUrl, storeProperties); } catch (ErrorCodeIOException errorCodeIOException) { throw new OpenOfficeException( "conversion failed: could not save output document; OOo errorCode: " + errorCodeIOException.ErrCode, errorCodeIOException); } catch (Exception otherException) { throw new OpenOfficeException("conversion failed: could not save output document", otherException);补充：基于libreoffice和jodconverter的文件在线预览插件，这个插件功能强大，使用简单
