在线编辑器（WangEditor）
  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，当然了是先百度了资料，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。效果图：
  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。
