項目中要實現編輯器生成帶格式的html文檔,存入模板,最後生成html的URL,因此選擇了UEditor。css
UEditor是由百度WEB前端研發部開發的所見即所得的開源富文本編輯器,具備輕量、可定製、用戶體驗優秀等特色。html
以前沒有接觸過編輯器,從頭開始摸索。看API,看網上的例子。以前,用的是UMeditor,是UEditor的mini版本。用的人少,例子也少。讓我很苦惱。以後又換回了完整版。前端

我是JSP版本。ueditor1_4_3-utf8-jsp,解壓後,放入工程中。nginx
將ueditor/jsp/lib下的jar包導入WEB-INF下lib下,maven工程導入外部jar方法,以下:web
例子:spring
<dependency> <groupId>cn.com.umeditor</groupId> <artifactId>json</artifactId> <version>1.0</version> <scope>system</scope> <systemPath>${project.basedir}/src/main/webapp/WEB-INF/lib/json.jar</systemPath> </dependency>
編輯本身的JSP頁面:數據庫
<%@ page language="java" contentType="text/html; charset=utf-8" pageEncoding="utf-8"%> <html> <head> <meta http-equiv="Content-Type" content="text/html; charset=UTF-8"> <title>惠民網消息推送平臺</title> <meta charset="utf-8"> <script src="<%=request.getContextPath() %>/ueditor/ueditor.config.js"></script> <script src="<%=request.getContextPath() %>/ueditor/ueditor.all.min.js"></script> <script src="<%=request.getContextPath() %>/ueditor/lang/zh-cn/zh-cn.js"></script> <script src="<%=request.getContextPath() %>/ueditor/third-party/jquery-1.10.2.min.js"></script> <link href="<%=request.getContextPath() %>/ueditor/themes/iframe.css" type="text/css" rel="stylesheet"> <link href="<%=request.getContextPath() %>/ueditor/themes/default/css/ueditor.css" type="text/css" rel="stylesheet"> <link href="<%=request.getContextPath() %>/ueditor/third-party/codemirror/codemirror.css" type="text/css" rel="stylesheet"> </head> <style type="text/css"> div{ width:100%; } </style> <body> <form method="post" action="<%=request.getContextPath() %>/test/test.do"> <br>類別:<input type="text" name="stype" /> 標題:<input type="text" name="title" /> <br/> <!--style給定寬度能夠影響編輯器的最終寬度--> <!-- 加載編輯器的容器 --> <!-- 實例化編輯器 --> <script id="editor" type="text/plain" style="width:1024px;height:500px;"></script> <script type="text/javascript"> var ue = UE.getEditor('editor'); </script> <input type="submit" value="提交"/> </form> </body> </html>
遇到的錯誤:1)var ue = UE.getEditor('editor'); 報錯緣由:js引入錯誤,路徑錯誤/引入順序錯誤。
2)表情包,html頁面都是404.路徑都對,文件也存在,就是找不到。錯誤緣由:spring攔截器問題。(表情包要再官網下載後導入到程序中,下載的包裏面有很詳細的導入方法。)
錯誤解決就能夠啓動tomcat進行展現頁面了。
因爲上傳圖片/上傳文件都保存到本地的tomcat下,下次啓動,文件/圖片就會消失。根據業務需求,都是把圖片/文件存到服務器下。或者本地的其它路徑。
而後UEditor的上傳代碼都是寫到源碼中了。讓我一陣糾結。百度了一下,搜到了一個很是棒的例子,符合我項目,符合框架,什麼都符合,下載源碼進行實驗。

一切準備就緒,開始上傳。
顯示上傳到本地 保存一份後,在進行服務器上傳。
前兩個 因爲網絡,上傳阿里雲失敗。本地保存成功。
後一個 上傳成功了。成功後回顯回來。
