Ckeditor一种很方便的文本编辑器
ckeditor官网: http://ckeditor.com/
这里介绍ckeditor的其中一个的用法,自己做小项目练手非常的适合,上手非常的快。
首先去官网下载这个东西,链接:http://pan.baidu.com/s/1nuXePuD 密码:rrr0,需要特别说明一下,这个东西需要配置,但是具体配置我也不是很清楚,所以你看到着篇博客,练习的话,最后使用上面上传的这个东西,目录呢,如图所示。
1:首先将这个ckeditor文件夹放到webcontent目录下面,然后进行开发。
使用这个文本编辑器的最重要的一句话是:
<script type="text/javascript" src="http://www.mamicode.com/resource/ckeditor/ckeditor.js"></script>
然后在所需使用的地方引入这个:class="ckeditor",如下所示:
<textarea class="ckeditor" id="newsContent" name="newsContent" rows="15" placeholder="请输入内容"> </textarea>
完整的代码如下所示,文件名是news.jsp
1 <%@ page language="java" contentType="text/html; charset=UTF-8" 2 pageEncoding="UTF-8"%> 3 <% 4 //获取绝对路径路径 ,开发项目一定要使用绝对路径,不然肯定出错 5 String path = request.getContextPath(); 6 String basePath = request.getScheme() + "://" 7 + request.getServerName() + ":" + request.getServerPort() 8 + path + "/"; 9 %> 10 <!DOCTYPE html >11 <html>12 <head>13 <base href="http://www.mamicode.com/">14 <meta http-equiv="Content-Type" content="text/html; charset=UTF-8">15 <title>新闻发布</title>16 17 <!-- 新 Bootstrap 核心 CSS 文件 -->18 <link rel="stylesheet" href="http://www.mamicode.com/resource/css/bootstrap.min.css">19 20 <!-- jQuery文件。务必在bootstrap.min.js 之前引入 -->21 <script src="http://www.mamicode.com/resource/js/jquery.min.js"></script>22 23 <!-- 最新的 Bootstrap 核心 JavaScript 文件 -->24 <script src="http://www.mamicode.com/resource/js/bootstrap.min.js"></script>25 26 <script type="text/javascript" src="http://www.mamicode.com/resource/ckeditor/ckeditor.js"></script>27 </head>28 <body>29 <div class="container">30 <h1 class="page-header">新闻发布</h1>31 <form class="form-horizontal" action="newsServlet" method="post">32 <div class="form-group">33 <label for="newsMan" class="col-sm-1 control-label">发布人</label>34 <div class="col-sm-4">35 <input class="form-control " name="newsMan" id="newsMan" placeholder="请输入发布人"/>36 </div>37 </div>38 <div class="form-group">39 <label for="newsTitle" class="col-sm-1 control-label">新闻标题</label>40 <div class="col-sm-6">41 <input class="form-control " name="newsTitle" id="newsTitle" placeholder="请输入新闻标题"/>42 </div>43 </div>44 <div class="form-group">45 <label for="newsContent" class="col-sm-1 control-label">新闻内容</label>46 <div class="col-sm-11">47 <textarea class="ckeditor" id="newsContent" name="newsContent" rows="15" placeholder="请输入内容"></textarea>48 </div>49 </div>50 51 <div class="form-group">52 <div class="col-sm-4 col-sm-offset-1">53 <input type="submit" value="http://www.mamicode.com/发 布 新 闻" class="btn btn-success btn-lg"/>54 </div>55 </div>56 </form> 57 </div>58 </body>59 </html>
2:这个jsp提交到servlet这个页面,完整代码如下所示,当然了,这里没有设计到数据库,因为涉及到数据库,更难理解和讲解,这里学会使用,自己摸索不是很难哦。
文件名是:NewsServlet.java
1 package com.liu.servlet; 2 3 import java.io.IOException; 4 import javax.servlet.ServletException; 5 import javax.servlet.annotation.WebServlet; 6 import javax.servlet.http.HttpServlet; 7 import javax.servlet.http.HttpServletRequest; 8 import javax.servlet.http.HttpServletResponse; 9 10 @WebServlet("/newsServlet")11 public class NewsServlet extends HttpServlet {12 13 14 private static final long serialVersionUID = 1L;15 16 protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {17 //设置字符编码格式18 request.setCharacterEncoding("utf-8");19 20 //获取从前台传来的参数21 String newsMan = request.getParameter("newsMan");22 String newsTitle = request.getParameter("newsTitle");23 String newsContent = request.getParameter("newsContent");24 25 //控制台输出测试内容26 System.out.println("newsMan:"+newsMan);27 System.out.println("newsTitle:"+newsTitle);28 System.out.println("newsContent:"+newsContent);29 30 //将获取的参数保存到request域中31 request.setAttribute("newsMan", newsMan);32 request.setAttribute("newsTitle", newsTitle);33 request.setAttribute("newsContent", newsContent);34 35 //重定向操作36 request.getRequestDispatcher("/index.jsp").forward(request, response);37 }38 39 }
3:上面的servlet页面又重定向到了index.jsp,如下所示:
1 <%@ page language="java" contentType="text/html; charset=UTF-8" 2 pageEncoding="UTF-8"%> 3 <% 4 //获取绝对路径路径 ,开发项目一定要使用绝对路径,不然肯定出错 5 String path = request.getContextPath(); 6 String basePath = request.getScheme() + "://" 7 + request.getServerName() + ":" + request.getServerPort() 8 + path + "/"; 9 %> 10 <!DOCTYPE html >11 <html>12 <head>13 <base href="http://www.mamicode.com/">14 <meta http-equiv="Content-Type" content="text/html; charset=UTF-8">15 <title>新闻发布</title>16 17 <!-- 新 Bootstrap 核心 CSS 文件 -->18 <link rel="stylesheet" href="http://www.mamicode.com/resource/css/bootstrap.min.css">19 20 <!-- jQuery文件。务必在bootstrap.min.js 之前引入 -->21 <script src="http://www.mamicode.com/resource/js/jquery.min.js"></script>22 23 <!-- 最新的 Bootstrap 核心 JavaScript 文件 -->24 <script src="http://www.mamicode.com/resource/js/bootstrap.min.js"></script>25 26 <script type="text/javascript" src="http://www.mamicode.com/resource/ckeditor/ckeditor.js"></script>27 </head>28 <body>29 <div class="container">30 <h1 class="page-header">查看新闻</h1>31 <form class="form-horizontal" action="newsServlet" method="post">32 <div class="form-group">33 <label for="newsMan" class="col-sm-1 control-label">发布人</label>34 <div class="col-sm-4">35 <p class="form-control-static">${newsMan }</p>36 </div>37 </div>38 <div class="form-group">39 <label for="newsTitle" class="col-sm-1 control-label">新闻标题</label>40 <div class="col-sm-6">41 <p class="form-control-static">${newsTitle }</p>42 </div>43 </div>44 <div class="form-group">45 <label for="newsContent" class="col-sm-1 control-label">新闻内容</label>46 <div class="col-sm-11">47 <p class="form-control-static">${newsContent }</p>48 </div>49 </div>50 </form>51 </div>52 </body>53 </html>
4:特比需要注意的是下面这个servlet,只要复制粘贴会使用即可,,不比关心其代码
1 package com.liu.servlet; 2 3 import java.io.IOException; 4 import java.io.PrintWriter; 5 import java.util.UUID; 6 7 import javax.servlet.ServletException; 8 import javax.servlet.annotation.MultipartConfig; 9 import javax.servlet.annotation.WebServlet;10 import javax.servlet.http.HttpServlet;11 import javax.servlet.http.HttpServletRequest;12 import javax.servlet.http.HttpServletResponse;13 import javax.servlet.http.Part;14 15 @WebServlet("/upLoad")16 @MultipartConfig17 public class UpLoadServlet extends HttpServlet {18 19 20 private static final long serialVersionUID = 1L;21 22 protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {23 request.setCharacterEncoding("utf-8");24 25 //获取文件的part26 Part part = request.getPart("upload");27 28 //获取请求的信息29 String requestinfo = part.getHeader("content-disposition");30 System.out.println(requestinfo);31 32 //获取文件的后缀名33 String str = requestinfo.substring(requestinfo.lastIndexOf("."),requestinfo.length()-1);34 System.out.println("后缀名:"+str);35 36 //获取上传文件的目录37 String root = request.getServletContext().getRealPath("//upload");38 System.out.println(root);39 40 //重新创建文件名41 String filename = UUID.randomUUID().toString()+str;42 String url = root+"\\"+filename;43 System.out.println(url);44 part.write(url);45 46 47 //响应48 PrintWriter out = response.getWriter();49 //获取路径50 String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort();51 52 String callback = request.getParameter("CKEditorFuncNum");53 54 out.print("<script>window.parent.CKEDITOR.tools.callFunction("+callback+",‘"+basePath+request.getContextPath()+"/upload/"+filename+"‘) </script>");55 56 out.flush();57 out.close();58 }59 60 }
5:最后说一下需要注意的地方:
其一就是如下图所示的config.js文件,这里需要修改一下文件内容
如下图所示,将ckeditor修改为自己的项目名称即可;
演示效果:
还有完善的空间,继续加油哦。别先生
