如何使用MS Office与专有的Java后端文档系统

top*_*at3 10 java sharepoint ms-office ms-wopi

目前我有一个文档系统,可以在一个iframe中的Star Office或LibreOffice中启动文档.

移至未来我理想地希望保留我拥有的文档系统,但将其集成到SharePoint中,以便我们能够使用MS Office打开和编辑文档.

由于没有Java Api与MS Office集成,这就是我选择使用SharePoint的原因.

我可以设法从sharepoint页面上的链接加载我的文档,但后来很难操纵MS Office中的保存功能并确保我的文档不会保存在sharepoint中.

有没有人做过类似的事情.

基本上我只想使用MS Office与我的文档进行交互,而无需在sharepoint中存储内容.所以我需要访问保存功能等.

据我所知,Apache POI不是一个可行的解决方案,因为它没有物理打开文档并允许用户单击文件 - >保存.我的理解是,它可以通过在代码中操作文档来操作文档,但不能使用办公室中的任何控件.

我在这里阅读http://msdn.microsoft.com/en-us/library/office/bb462633(v=office.12).aspx?cs-save-lang=1&cs-lang=vb#code-snippet- 2你可以在办公室重新调整命令并修改功能区吗？

谢谢你的建议

看起来可以使用WOPI和Office Web Apps.基本上需要创建一个WOPI应用程序

我有同样的问题,所以我实际上用Apache POI和SVG编辑了一个快速PPT编辑器..但后来我切换到Office Web Apps ..这里是WOPI服务器的快速实现,我是一个Java家伙所以我的.NET技能非常糟糕.编写servlet应该是微不足道的.

逻辑很简单:

将WOPISrc传递给办公室Web应用程序 - 这基本上是您的WOPI服务器的URL,其中包含文件位置.您现在可以忽略access_token/access_token_ttl.

Office Web Apps使用至少2个请求点击WOPISrc网址:

它将是一个元数据请求,它基本上是对WOPIsrc的GET调用.您将创建一个WOPI(CheckFileInfo)对象,并将其以JSON编码的形式发送回办公室Web应用程序.
现在Office Web Apps将自己请求文件,它将(/ contents)附加到WOPIsrc的末尾.所以只需以二进制格式发回.
(可选)Office Web Apps将在保存时对(WOPISrc +"/ contents")进行POST.您可以从POST获取数据并保存到磁盘.

注意:Word不起作用:/您只能查看,您需要实现Cobalt协议(FSSHTTP)的编辑.我正在研究这个主题,但是用C#编写它会更容易,因为你可以抓住一个Cobalt程序集.否则,此协议使用BASE64编码的二进制消息(FSSHTTPB)实现SOAP(FSSHTTP)

使用以下内容打开Office Web Apps:
