关于Ueditor富文本编辑器的配置和使用心得

一、环境和项目架构

本文章只是为了便于我个人记录日常笔记，如有错误或缺陷，请指出，文章仅供参考，如有转载请附上本文章链接。

介绍：将Ueditor富文本提交的内容直接生成Html文件，传到后台直接保存在项目下的webapp/files文件夹中，便于今后直接调用生成的Html。

1.环境

Eclipse+Maven+SpringBoot+JDK1.8

2.项目架构

             

二、项目代码

1.SpringBoot启动类（UeditorStater.java）

package com;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.autoconfigure.jdbc.DataSourceAutoConfiguration;
import org.springframework.context.annotation.ComponentScan;

//扫描的包
@ComponentScan(basePackages="com.controller")
@SpringBootApplication(exclude= {DataSourceAutoConfiguration.class})
public class UeditorStarter {
        public static void main(String[] args) {
            SpringApplication.run(UeditorStarter.class, args);

        }
}

2.Controller层（HtmlProductController.java）

说明：这里的作用是获取前端传输的文件对象，将其转存到项目下的/webapp/files文件夹。

package com.controller;

import java.io.File;
import java.io.IOException;
import java.text.SimpleDateFormat;
import java.util.Date;
import java.util.HashMap;
import java.util.Map;

import javax.servlet.http.HttpServletRequest;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.bind.annotation.ResponseBody;
import org.springframework.web.multipart.MultipartFile;

@Controller
@RequestMapping("/HtmlProductController.do")
public class HtmlProductController {
    @ResponseBody
    @RequestMapping(params = "fileUpload")
    public Map<String, Object> fileUpload(HttpServletRequest request,@RequestParam(value = "files", required = false) MultipartFile multipartFile) throws IOException {
        Map<String, Object> resultMap = new HashMap<String, Object>();
        String realpath = "";
        // 获取文件名
        String name = "";
        if (multipartFile != null) {
            try {
                name = multipartFile.getOriginalFilename();// 直接返回文件的名字
                String subffix = name.substring(name.lastIndexOf(".") + 1, name.length());// 我这里取得文件后缀
                String fileName = new SimpleDateFormat("yyyyMMddHHmmss").format(new Date());// 文件保存进来，我给他重新命名，数据库保存有原本的名字，所以输出的时候再把他附上原本的名字就行了。
                String filepath = request.getServletContext().getRealPath("/") + "files\\";// 获取项目路径到webapp
                File file = new File(filepath);
                if (!file.exists()) {// 目录不存在就创建
                    file.mkdirs();
                }
                multipartFile.transferTo(new File(file + "\\" + fileName + "." + subffix));// 保存文件
                realpath = file + "\\" + fileName + "." + subffix;
                resultMap.put("success", true);
                resultMap.put("code", 0);
                resultMap.put("msg", "上传成功");
            } catch (IllegalStateException e) {
                resultMap.put("success", false);
                resultMap.put("code", -1);
                resultMap.put("msg", "上传失败");
                e.printStackTrace();
            }
        }
        return resultMap;
    }
}

4.Test1.html

说明：这个页面是最基本的Ueditor初始化界面。

<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>Insert title here</title>
    <script type="text/javascript" src="js/ueditor/ueditor.config.js"></script>
    <script type="text/javascript" src="js/ueditor/ueditor.all.min.js"></script>
    <script type="text/javascript" src="js/ueditor/lang/zh-cn/zh-cn.js" charset="utf-8" ></script>
</head>
<body>
            <form action="" method="post">
                <div style="width:100%">
                    <script type="text/plain" id="myEditor" style="width:100%;height:260px"></script>
                </div>
                </form>
</body>
<script type="text/javascript">
    UE.getEditor("myEditor");
</script>
</html>

5.Test2.html

说明：这个页面新增了生成的页面中的代码高亮部分，这是Ueditor自带的高亮插件。

<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>Insert title here</title>
    <script type="text/javascript"src="https://cdn.bootcss.com/jquery/3.2.1/jquery.js"></script>
    <script type="text/javascript" src="js/ueditor/ueditor.config.js"></script>
    <script type="text/javascript" src="js/ueditor/ueditor.all.min.js"></script>
    <script type="text/javascript" src="js/ueditor/lang/zh-cn/zh-cn.js" charset="utf-8" ></script>

</head>
<body>
            <form action="" method="post">
                <div style="width:100%">
                    <script type="text/plain" id="myEditor" style="width:100%;height:150px"></script>
                </div>
                </form>
                 <button id="btn">提交</button>
</body>
<script type="text/javascript">
   var ue= UE.getEditor("myEditor");
    $("#btn").click(function(){
         var html= ue.getAllHtml();
         alert(html);
         html=html+"<link href='../js/ueditor/third-party/SyntaxHighlighter/shCoreDefault.css' rel='stylesheet' type='text/css'/>";
         html=html+"<script type='text/javascript' src='../js/ueditor/third-party/SyntaxHighlighter/shCore.js' "+"></"+"script>";
         html=html+"<script type='text/javascript'> SyntaxHighlighter.all();</"+"script>";

         var blob=new Blob([html]);
         //blob转file
         var aafile = new File([blob], "aa.html");
         var formdata = new FormData();
         console.log(aafile);
         formdata.append("files", aafile);
         console.log(formdata.get("files"));
         $.ajax({
               url:'HtmlProductController.do?fileUpload',
               type:'POST',
              data:formdata,
              contentType:false,
              processData:false,//这个很有必要，不然不行
              dataType:"json",
              mimeType:"multipart/form-data",
             success: function (data) {
                 alert("上传成功");
             }
          });
    });
</script>
</html>

效果图：

6.Test3.html

说明：这个页面也修改了代码高亮样式，与Test2.html不同的是，这里采用了highlight插件，即项目架构的js文件夹下的highlight文件夹。

<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>Insert title here</title>
    <script type="text/javascript"src="https://cdn.bootcss.com/jquery/3.2.1/jquery.js"></script>
    <script type="text/javascript" src="js/ueditor/ueditor.config.js"></script>
    <script type="text/javascript" src="js/ueditor/ueditor.all.min.js"></script>
    <script type="text/javascript" src="js/ueditor/lang/zh-cn/zh-cn.js" charset="utf-8" ></script>

</head>
<body>
            <form action="" method="post">
                <div style="width:100%">
                    <script type="text/plain" id="myEditor" style="width:100%;height:150px"></script>
                </div>
                </form>
                 <button id="btn">提交</button>
</body>
<script type="text/javascript">
   var ue= UE.getEditor("myEditor");
    $("#btn").click(function(){
         var html= ue.getAllHtml();
         alert(html);
         //黑色高亮
         html=html+"<link rel='stylesheet' type='text/css' href='../js/highlight/styles/school-book.css'>";
         html=html+"<script type='text/javascript' src='../js/highlight/highlight.pack.js' "+"></"+"script>";
         html=html+"<script type='text/javascript'>hljs.initHighlightingOnLoad(); var allpre = document.getElementsByTagName('pre');var allpre = document.getElementsByTagName('pre'); for(i = 0; i < allpre.length; i++){  var onepre = document.getElementsByTagName('pre')[i]; var mycode = document.getElementsByTagName('pre')[i].innerHTML;onepre.innerHTML = '<code id="+"mycode"+">'+mycode+'</code>';} </"+"script>";
         html=html+"<style type='text/css'>#mycode{  font-size: 16px;font-family:'微软雅黑'; font-weight:500;white-space: pre;}</style>";
         var blob=new Blob([html]);
         //blob转file
         var aafile = new File([blob], "aa.html");
         var formdata = new FormData();
         console.log(aafile);
         formdata.append("files", aafile);
         console.log(formdata.get("files"));
         $.ajax({
               url:'HtmlProductController.do?fileUpload',
               type:'POST',
              data:formdata,
              contentType:false,
              processData:false,//这个很有必要，不然不行
              dataType:"json",
              mimeType:"multipart/form-data",
              success: function (data) {
                 alert("上传成功");
             }
          });
    });
</script>
</html>

效果图：

其实，更换“ html=html+"<style type='text/css'>#mycode{  font-size: 16px;font-family:'微软雅黑'; font-weight:500;white-space: pre;}</style>";”中的样式就可以更换代码的样式辣。

另外，更换Test3.html中的“html=html+"<link rel='stylesheet' type='text/css' href='../js/highlight/styles/school-book.css'>";”中红字css文件，可以改变代码的主题样式，这些样式都存放在了js/highlight/styles/文件夹下。以下将展示一些效果图，各位喜欢哪个就用哪个吧。
