  • 需求

公司一個小項目要結尾了, 有很是多的表格, 並且很是複雜, 例如html

在這裏插入圖片描述
例如：（這表格, 有想死的心…）
在這裏插入圖片描述前端

看到這樣的表格，第一反應是n臉懵逼，這得作到啥時候啊，最後想到用一個方法，讓客戶本身玩！！
平臺提供Excel模版下載，客戶下載填寫完再提交Excel，平臺再將Excel轉PDF，順便將PDF轉成圖片，給前端展現，想法簡單，方案可行，開工！java

  • 方案:
  1. windows server下用 jacob, windows上可完美運行, 可是！！！Linux上不支持jacob！！！（很是重要！！）
  2. poi + iText，貌似不錯
  3. openoffice，跨平臺

本文選用openoffice，各位看官可自選用iText + poi，本身判別！固然也能夠用jacob，前提是你不須要在Linux中運行項目。linux

  1. win：
    win版本
    下載完成後，一路next，最好默認路徑安裝，省得折騰
    完成後 Win + R 填入 Dcomcnfg 打開組件服務
    在這裏插入圖片描述
    設置openoffice組件服務， 都設成SYSTEM
    在這裏插入圖片描述
    再設置標識爲：交互式用戶
    在這裏插入圖片描述

進入到安裝目錄，若是路徑是默認的，則在 C:\Program Files (x86)\OpenOffice 4\program 下面，
進到這個路徑下，按住 shift 再點擊鼠標右鍵，在此處打開命令窗口，輸入 soffice -headless-accept=「socket,host=127.0.0.1,port=8100;urp;」-nofirststartwizard， 查看是否啓動成功， 黑窗口輸入 netstat -ano
在這裏插入圖片描述
在這裏插入圖片描述
windows下安裝完畢！git

  1. linux：下載傳送門
    在這裏插入圖片描述
    根據本身的Linux系統選擇RPM包或者DEB，若是是Ubuntu則選DEB，其餘就選RPM包，查看當前操做系統是ubuntu仍是centos

LSB Version:	:(略)
Distributor ID:	CentOS
Description:	CentOS Linux release (略)

下載完畢後，利用ssh工具上傳到服務器上！web
