java office轉pdf

java office 轉 pdf支持所有文檔格式。

準備環境:java開發環境（不多說）,centos 7(一枚),LibreOffice安裝包(下載地址:https://zh-cn.libreoffice.org/)

LibreOffice此處下載最穩定版本

1.安裝LibreOffice_5.3.7_Linux_x86-64_rpm.tar.gz

解壓

tar -xzvf LibreOffice_5.3.7_Linux_x86-64_rpm.tar.gz

解壓後得到LibreOffice_5.3.7.2_Linux_x86-64_rpm目錄

cd LibreOffice_5.3.7.2_Linux_x86-64_rpm/PRMS

切換到安裝目錄

rpm -ivh -f --nodeps *.rpm

安裝所有的rpm
默認安裝在opt下

2.給LibreOffice添加中文字體

上傳到

/opt/libreoffice5.3/share/fonts/truetype

3.測試轉換
上傳一個office

./soffice -headless -invisible -convert-to pdf /tmp/test/test.doc -outdir /tmp/test/

執行的是報錯

/opt/libreoffice5.3/program/oosplash: error while loading shared libraries: libXinerama.so.1: cannot open shared object file: No such file or directory

需要安裝依賴

yum  install -y libXinerama

再次測試轉換

/opt/libreoffice5.3/program/soffice.bin: error while loading shared libraries: libcairo.so.2: cannot open shared object file: No such file or directory

yum install -y ibus

再次測試轉換

終於轉換成功了。

xshell 用sz命令。下載到本地查看轉換效果。效果還不錯

啓動服務

/opt/libreoffice5.3/program/soffice -headless -accept="socket,host=127.0.0.1,port=8100;urp;" -nofirststartwizard &
