This article is to share with you about Pageoffice how to combine fastdfs online editing and preview office documents, editor feel very practical, so share with you to learn, I hope you can get something after reading this article, say no more, follow the editor to have a look.

Background: the documents of our project are stored on the fastdfs server, and the existing requirements need to preview, edit and save all kinds of office documents on fastdfs on the website page.

Solution: since fastdfs currently does not support document updates, it can only be achieved by inserting new documents and deleting old documents. At the same time, the file uuid stored in the original database table needs to be updated, and then pageoffice can only support the preview and editing of documents in this server, so you need to download the file in the fastdfs server in the application server, then save it as a temporary file locally, and then preview and edit it for pageoffice. Save and then delete and insert to update the fastdfs file, so as to achieve the purpose.

Add: temporary files downloaded by the resulting application server need to be cleaned regularly

Most of the code can be found in the documentation on pageoffice's official website.

PageOffice 4.5 for JAVA (IE, Chrome, Firefox versions are also supported)

PageOffice 4.5 for Spring Boot [sample code]

Put the code:

Pageoffice initial configuration class

@ Configuration

Public class PageOfficeConfiguration {

/ * *

* add server-side authorization program Servlet for PageOffice (required)

, /

@ Bean

Public ServletRegistrationBean servletRegistrationBean () {

Com.zhuozhengsoft.pageoffice.poserver.Server poserver = new com.zhuozhengsoft.pageoffice.poserver.Server ()

/ / set the directory where the license.lic file is stored after PageOffice registration is successful

/ / the server can be stored in / geelyapp/pageoffice

Poserver.setSysPath ("d:\\ lic\")

ServletRegistrationBean srb = new ServletRegistrationBean (poserver)

Srb.addUrlMappings ("/ xx/pageoffice/poserver.zz")

Srb.addUrlMappings ("/ xx/pageoffice/posetup.exe")

Srb.addUrlMappings ("/ xx/pageoffice/pageoffice.js")

Srb.addUrlMappings ("/ xx/pageoffice/jquery.min.js")

Srb.addUrlMappings ("/ xx/pageoffice/pobstyle.css")

Srb.addUrlMappings ("/ xx/pageoffice/sealsetup.exe")

Return srb;//

}

}

Apply the controller class

@ Controller

@ RequestMapping ("/ xx/pageoffice")

@ Api (value = "document online editing interface")

Public class PageOfficeController {

@ Value ("${pageoffice.path.doc:'D:/doc/'}")

@ RequestParam (name = "filePath", required = true) String filePath

Map map) {

Map.put ("busi", busi)

Map.put ("filePath", filePath)

ModelAndView mv = new ModelAndView ("Index")

Return mv

}

@ RequestMapping (value= "/ word", method=RequestMethod.GET)

Public ModelAndView showWord (HttpServletRequest request, Map map

RequestParam (name = "filePath", required = false) String filePath) {

String [] param = busi.split ("%"); / / here, the call cannot be successful because it is compiled to & when multiple parameters are passed using & match

Busi = param [0]

FilePath = param [2]

/ / pageofficeDocPath = "D:\\ doc\\"; / / available in the local development environment

String [] filePathArr = filePath.split ("/")

String url = pageofficeDocPath+ filePathArr [filePathArr.length-1]

LOGGER.info ("showWord url:" + url)

File tmpFile = new File (url)

Try (FileOutputStream fos = new FileOutputStream (tmpFile)) {

Fos.write (this.storageService.readFileContent (filePath))

} catch (Exception e) {

LOGGER.error ("Preview temporary file generation error", e)

}

/ /-the calling code of PageOffice starts-

Map.put ("pageoffice", poCtrl.getHtmlCode ("PageOfficeCtrl1"))

/ /-the end of the calling code of PageOffice

/ / because fastdfs does not support file updates

/ / currently considering deleting the original file and regenerating the file

/ / after TODO, you can consider the update of the supporting file, that is, the frame is used to delete and insert, and the newly inserted uuid needs to be consistent with the deleted one.

String newCode = this.storageService.store (fs.getFileName (), fs.getFileStream ())

/ / update the document uuid in the original business table
