SpringBoot 2.x + Layui + UEditor 实现富文本编辑器，实现图片/文件/视频上传回显
一、下载 UEditor 源码
UEditor 官网： UEditor 官网
UEditor GitHub 地址：UEditor GitHub 地址
下载最新版的源码：
二、使用 grunt 打包源代码
node.js 和 grunt 的安装和使用请自行百度
打包详细教程见 UEditor 官网：使用grunt打包源代码
1、在 UEditor 源码根目录打开命令提示符窗口
2、安装打包需要的grunt插件
在命令提示符输入命令：npm install
这个命令会根据 package.json 文件，安装打包需要的 grunt 和 grunt 插件，安装结束后，会在 ueditor 目录下出现一个 node_modules 文件夹。
3、执行打包命令
在命令提示符输入命令：grunt --encode=utf8 --server=jsp
出现 Done, without errors. 时，打包完成。
这个命令会根据 Gruntfile.js 执行打包的任务，运行过程需要 java 环境 支持。
命令完成后，ueditor 目录下会出现 dist/ 目录，里面有你要的打包好的 ueditor 文件夹，默认是 utf8-jsp 文件夹。
执行打包grunt命令时，可以传入编码和后台语言的参数：
1、支持两种编码指定：–encode参数
- utf8 (默认编码)
- gbk
2、提供四种后台语言支持：–server参数
- php (默认语言)
- jsp
- net (代表.net后台)
- asp
三、下载 Layui
Layui 官网： Layui 官网
四、配置 SpringBoot 项目
1、依赖
<dependencies>
<!-- ueditor 依赖 -->
<dependency>
<groupId>commons-fileupload</groupId>
<artifactId>commons-fileupload</artifactId>
<version>1.3.1</version>
</dependency>
<dependency>
<groupId>commons-io</groupId>
<artifactId>commons-io</artifactId>
<version>2.4</version>
</dependency>
<dependency>
<groupId>commons-codec</groupId>
<artifactId>commons-codec</artifactId>
<version>1.9</version>
</dependency>
<!--阿里 FastJson依赖-->
<dependency>
<groupId>com.alibaba</groupId>
<artifactId>fastjson</artifactId>
<version>1.2.39</version>
</dependency>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-thymeleaf</artifactId>
</dependency>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
</dependency>
<dependency>
<groupId>org.mybatis.spring.boot</groupId>
<artifactId>mybatis-spring-boot-starter</artifactId>
<version>2.1.4</version>
</dependency>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-devtools</artifactId>
<scope>runtime</scope>
<optional>true</optional>
</dependency>
<dependency>
<groupId>mysql</groupId>
<artifactId>mysql-connector-java</artifactId>
<scope>runtime</scope>
</dependency>
<dependency>
<groupId>org.projectlombok</groupId>
<artifactId>lombok</artifactId>
<optional>true</optional>
</dependency>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-test</artifactId>
<scope>test</scope>
</dependency>
</dependencies>
2、目录结构
1、把 UEditor 打包生成的 dist/utf8-jsp 文件夹复制到 static 文件夹下，并把 utf8-jsp 文件夹重命名为 ueditor
2、把 layui 文件夹复制到 static 文件夹下
3、在 resources 文件夹下新建文件夹 lib，把 ueditor\jsp\lib 下的 ueditor-1.1.2.jar 文件复制到 static/lib 文件夹下（其他四个 jar 已在 Maven 添加依赖）
4、在项目中添加 jar 包
在 project structure 中引入该 lib
引入 jar 包
3、使用 UEditor
①、创建 ueditor.html 文件
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<link rel="stylesheet" href="/layui/css/layui.css">
<script src="/layui/layui.js"></script>
<script src="/js/jquery-3.3.1.min.js"></script>
<script src="/ueditor/third-party/jquery-1.10.2.js"></script>
<!-- 配置文件 -->
<script src="/ueditor/ueditor.config.js"></script>
<!-- 编辑器源码文件 -->
<script src="/ueditor/ueditor.all.js"></script>
<script src="/ueditor/lang/zh-cn/zh-cn.js"></script>
<script src="/ueditor/ueditor.parse.js"></script>
</head>
<body>
<div align="center">
<br><br><br><br>
<textarea id="faq_edit" type="text" style="height: 500px; width: 1000px;"></textarea>
</div>
<script type="application/javascript">
layui.define(function () {
let ue = UE.getEditor('faq_edit');
});
</script>
</body>
</html>
②、在浏览器打开 ueditor.html
如果看到了下面这样的编辑器，恭喜你，初次部署成功（这里用了 Controller ）！
浏览器地址： http://localhost:8090/ueditor
初次使用会提示 后台配置项返回格式出错，上传功能将不能正常使用！
五、配置后端
1、服务器统一请求接口路径
配置 ueditor.config.js，设置服务器统一请求接口路径
不要改动 URL，这里只改动 serverURL
2、配置返回 JSON 包
打开 ueditor/jsp/config.json 文件，去掉注释，转化为 JSON
3、配置 UEditorController
/**
* @author wxhntmy
*/
@RestController
public class UEditorController {
private String config_json = "{\n" +
"\t\"imageActionName\": \"uploadimage\",\n" +
"\t\"imageFieldName\": \"upfile\",\n" +

"\t\"videoAllowFiles\": [\n" +
"\t\t\".flv\", \".swf\", \".mkv\", \".avi\", \".rm\", \".rmvb\", \".mpeg\", \".mpg\",\n" +
"\t\t\".ogg\", \".ogv\", \".mov\", \".wmv\", \".mp4\", \".webm\", \".mp3\", \".wav\", \".mid\"\n" +
"\t],\n" +
"\n" +
"\t\"fileActionName\": \"uploadfile\",\n" +
"\t\"fileFieldName\": \"upfile\",\n" +
"\t\"filePathFormat\": \"/ueditor/jsp/upload/file/{yyyy}{mm}{dd}/{time}{rand:6}\",\n" +

"\t\t\".rar\", \".zip\", \".tar\", \".gz\", \".7z\", \".bz2\", \".cab\", \".iso\",\n" +
"\t\t\".doc\", \".docx\", \".xls\", \".xlsx\", \".ppt\", \".pptx\", \".pdf\", \".txt\", \".md\", \".xml\"\n" +
"\t],\n" +
"\n" +
"\t\"imageManagerActionName\": \"listimage\",\n" +
"\t\"imageManagerListPath\": \"/ueditor/jsp/upload/image/\",\n" +

"\t]\n" +
"\n" +
"}";
@RequestMapping(value = "/ueditor/jsp/action", method = {
RequestMethod.GET, RequestMethod.POST} )
public JSONObject action(@RequestParam String action){
System.out.println("action: " + action);
JSONObject jsonObject = JSONObject.parseObject(config_json);
System.out.println("jsonObject: " + jsonObject.toJSONString());
return jsonObject;
}
}
至此，再次打开浏览器，打开 ueditor.html（http://localhost:8090/ueditor） 文件，提示 后台配置项返回格式出错，上传功能将不能正常使用！ 的错误已经没有了。
浏览器输入地址： http://localhost:8090/ueditor/action?action=config 会返回 config.json
六、配置上传路径和回调
详细教程见 UEditor 官网：后端请求规范
1、上传
重新编辑 UEditorController 的 action 方法，请求类型改为 GET
@RequestMapping(value = "/ueditor/action", method = RequestMethod.GET )
public Object action(@RequestParam String action){
System.out.println("action: " + action);
switch (action){
//执行上传图片或截图的action名称
case "uploadimage":
break;
//执行上传涂鸦的action名称
case "uploadscrawl":
break;
//执行上传视频的action名称
case "uploadvideo":
break;
//controller里,执行上传视频的action名称
case "uploadfile":
break;
//执行抓取远程图片的action名称
case "catchimage":
break;
//执行列出图片的action名称
case "listimage":
break;
//执行列出文件的action名称
case "listfile":
break;
default:
break;
}
JSONObject jsonObject = JSONObject.parseObject(config_json);
//System.out.println("jsonObject: " + jsonObject.toJSONString());
return jsonObject;
}
再写一个同样 url 的 POST 方法，用于文件上传
/**
* 执行单个文件上传操作
* @param upfile 文件数据
* @return 响应json
*/
@RequestMapping(value = "/ueditor/action", method = RequestMethod.POST )
public Object action_upload(@RequestParam MultipartFile upfile){
System.out.println("upfile: " + upfile.getOriginalFilename());
String filename = upfile.getOriginalFilename();
String uuid = UUID.randomUUID().toString();
boolean boole = fileOperationService.saveFile(upfile, uuid);
Map<String, String> map = new HashMap<>();
if (boole) {
map.put("state", "SUCCESS");
map.put("url","/ueditor/download?uuid="+uuid);
map.put("title", filename);
map.put("original", filename);
} else {
map.put("state", "FAIL");
map.put("url","");
map.put("title", filename);
map.put("original", filename);
}
return map;
}
2、文件操作 Service
/**
* 保存文件
*
* @param file 文件
* @param uuid uuid
* @return 保存成功返回true
*/
@Override
public boolean saveFile(MultipartFile file, String uuid) {
try {
File path = path(file.getContentType());
String filename = file.getOriginalFilename();
ImgFile fileEntity = new ImgFile();
fileEntity.setFileName(filename);
fileEntity.setUuid(uuid);
String storeaddress = path.getAbsolutePath();
fileEntity.setStoreaddress(storeaddress);
File saveFile = new File(path, uuid);
try {
imgFileMapper.save(fileEntity);
file.transferTo(saveFile);
return true;
} catch (IllegalStateException | IOException e) {
e.printStackTrace();
return false;
}
} catch (Exception e) {
e.printStackTrace();
System.out.println("文件保存异常");
return false;
}
}
/**
* 检验文件路径是否存在
*
* @param type 文件类型
* @return
*/
@Override
public File path(String type) {
File path = new File(FILE_PATH);
if (!path.isDirectory()) {
path.mkdir();
}
return path;
}
/**
* 下载
*
* @param uuid
* @param request
* @param response
*/
@Override
public void download(String uuid, HttpServletRequest request, HttpServletResponse response) {
ImgFile fileentity = imgFileMapper.findByUuid(uuid);
String filename = fileentity.getFileName();
filename = getStr(request, filename);
File file = new File(fileentity.getStoreaddress(), uuid);
if (file.exists()) {
FileInputStream fis;
try {
fis = new FileInputStream(file);
response.setContentType("application/x-msdownload");
response.addHeader("Content-Disposition", "attachment; filename=" + filename);
ServletOutputStream out = response.getOutputStream();
byte[] buf = new byte[2048];
int n = 0;
while ((n = fis.read(buf)) != -1) {
out.write(buf, 0, n);
}
fis.close();
out.flush();
out.close();
} catch (IOException e) {
e.printStackTrace();
}
}
}
@Override
public String getStr(HttpServletRequest request, String fileName) {
String downloadFileName = null;
String agent = request.getHeader("USER-AGENT");
try {
if (agent != null && agent.toLowerCase().indexOf("firefox") > 0) {
//downloadFileName = "=?UTF-8?B?" + (new String(Base64Utils.encode(fileName.getBytes("UTF-8")))) + "?=";
//设置字符集
downloadFileName = "=?UTF-8?B?" + Base64Utils.encodeToString(fileName.getBytes("UTF-8")) + "?=";
} else {
downloadFileName = java.net.URLEncoder.encode(fileName, "UTF-8");
}
} catch (UnsupportedEncodingException e) {
e.printStackTrace();
}
return downloadFileName;
}
七、测试回显
1、图片回显
上传图片浏览器控制台无报错，图片回显正常！
2、添加附件
上传附件浏览器控制台无报错，文件回显正常！
3、上传视频
