自己之前写了一篇关于POI 相关的博客, 想了想在公司中一般常用的不就是上传下载,poi,分页,定时等。好像还有个在线编辑器, 于是自己就花了两个多小时把编辑器相关的代码撸了遍,当然了是先百度找了找资料,看了看实现的逻辑,然后自己撸的。 编辑器自己使用的是WangEditor,网上也有很多关于Editor,kindEitor 的文章, 不过貌似好像没用。业务方面:在编辑器中编辑, 然后保存为word,或者将word中的内容加载进在线编辑器中再次编辑。
http://www.wangeditor.com/ 这是WangEditor的相关网址,其中api,文档,实例都有。 WangEditor使用,配置还是相对来说比较简单的,引入相关js,创建editor对象,初始化对象。
editor.txt.html() 会将在编辑器中编辑的内容获取,然后你直接将其传入后台便可以获取到编辑器中编辑的内容。
当你使用编辑器编辑并保存后,会在指定的保存位置生成一个word,txt文件夹和一天个htm文件。txt文件夹中是txt文件。txt文件和htm文件都是自动生成的。其中txt文件里是HTML中的标签语言,当你要将word中的内容加载进编辑器再次编辑时,获取的内容是相对应的txt文件中的内容。htm文件只有一个,是刚使用用WangEditor创建word成功后生成的,其就是个HTML文件,其中的标签,属性对应的都是编辑器中展示的模样。当你保存生成word时,是先读取htm中的内容,将${content}替换成你编辑的内容,样式什么的htm文件中模板原先就有。然后利用流将HTML中的内容写入到word中并生成word。

其中主要的代码就是工具类,代码都是能直接使用的。当然了,代码我还有10%没弄上来,不过我相信有了这些代码,看到此篇博客的人应该没问题。
在此,希望此篇博客能帮助到一些人。
