        </dependency>

2. 下載Ueditor源碼

下載地址：??https://github.com/fex-team/ueditor/tree/dev-2.0.0??

3. Java代碼整合

將??ueditor-dev-2.0.0版本ueditorjspsrc??下的com文件夾整體復(fù)制到項(xiàng)目Java目錄下面

SpringBoot2.x 整合 Ueditor_spring boot_03

SpringBoot2.x 整合 Ueditor_html_04

SpringBoot2.x 整合 Ueditor_html_05

4. 靜態(tài)文件整合

①把??ueditor??整個文件夾復(fù)制到static目錄下面
②把??ueditorjspconfig.json??復(fù)制到ueditor的根目錄下面
③在resources目錄下面創(chuàng)建js文件夾存放??jquery2.1.3.min.js??

SpringBoot2.x 整合 Ueditor_html_06

二、靜態(tài)頁面+控制層

在??resources???目錄下面創(chuàng)建??templates??

三、配置調(diào)整

3.1. 圖片大小

當(dāng)用戶上傳的圖片太大時，為了不讓Ueditor不出現(xiàn)水平滾動軸，可以修改ueditor.all.js文件以及ueditor.all.mini.js文件

SpringBoot2.x 整合 Ueditor_spring boot_07

3.2. 修改ueditor.config.js

修改ueditor.config.js文件，在其中指定Ueditor請求的服務(wù)器端的路徑：

SpringBoot2.x 整合 Ueditor_java_08

3.3. 修改config.json文件

修改config.json文件，為其添加一個表示上傳資料基本路徑的變量basePath

SpringBoot2.x 整合 Ueditor_spring boot_09

3.4. 修改BinaryUploader

修改BinaryUploader的save()方法的代碼如下

public static final State save(HttpServletRequest request,
                   Map<String, Object> conf) {
    // FileItemStream fileStream = null;
    // boolean isAjaxUpload = request.getHeader( "X_Requested_With" ) != null;

    if (!ServletFileUpload.isMultipartContent(request)) {
      return new BaseState(false, AppInfo.NOT_MULTIPART_CONTENT);
    }

    // ServletFileUpload upload = new ServletFileUpload(
    //  new DiskFileItemFactory());
    //
    // if ( isAjaxUpload ) {
    //     upload.setHeaderEncoding( "UTF-8" );
    // }

    try {
      // FileItemIterator iterator = upload.getItemIterator(request);
      //
      // while (iterator.hasNext()) {
      //  fileStream = iterator.next();
      //
      //  if (!fileStream.isFormField())
      //    break;
      //  fileStream = null;
      // }
      //
      // if (fileStream == null) {
      //  return new BaseState(false, AppInfo.NOTFOUND_UPLOAD_DATA);
      // }
      MultipartHttpServletRequest multipartRequest = (MultipartHttpServletRequest) request;
      MultipartFile multipartFile = multipartRequest.getFile(conf.get("fieldName").toString());
      if(multipartFile==null){
        return new BaseState(false, AppInfo.NOTFOUND_UPLOAD_DATA);
      }

      String savePath = (String) conf.get("savePath");
      //String originFileName = fileStream.getName();
      String originFileName = multipartFile.getOriginalFilename();
      String suffix = FileType.getSuffixByFilename(originFileName);

      originFileName = originFileName.substring(0,
          originFileName.length() - suffix.length());
      savePath = savePath + suffix;

      long maxSize = ((Long) conf.get("maxSize")).longValue();

      if (!validType(suffix, (String[]) conf.get("allowFiles"))) {
        return new BaseState(false, AppInfo.NOT_ALLOW_FILE_TYPE);
      }

      savePath = PathFormat.parse(savePath, originFileName);

      //String physicalPath = (String) conf.get("rootPath") + savePath;
      String basePath=(String) conf.get("basePath");
      String physicalPath = basePath + savePath;

      //InputStream is = fileStream.openStream();
      InputStream is = multipartFile.getInputStream();
      State storageState = StorageManager.saveFileByInputStream(is,
          physicalPath, maxSize);
      is.close();

      if (storageState.isSuccess()) {
        storageState.putInfo("url", PathFormat.format(savePath));
        storageState.putInfo("type", suffix);
        storageState.putInfo("original", originFileName + suffix);
      }

      return storageState;
      // } catch (FileUploadException e) {
      //  return new BaseState(false, AppInfo.PARSE_REQUEST_ERROR);
    } catch (IOException e) {
    }
    return new BaseState(false, AppInfo.IO_ERROR);
  }

3.5. 修改ConfigManage類

修改成員變量configFileName的值為config.json的路徑值：

private static final String configFileName = "static/ueditor/config.json";

SpringBoot2.x 整合 Ueditor_java_10

在getConfig()方法的return語句之前添加如下代碼：

("basePath", this.jsonConfig.getString("basePath"));
    conf.put("savePath", savePath);
    conf.put("rootPath", this.rootPath);

SpringBoot2.x 整合 Ueditor_html_11

修改initEnv()方法
為了讓項(xiàng)目在打包后能正常夠上傳文件/圖片，修改initEnv()方法用Class類的getResourceAsStream()來讀取文件

private void initEnv() throws FileNotFoundException, IOException {
   File file = new File(this.originalPath);
   if (!file.isAbsolute()) {
      file = new File(file.getAbsolutePath());
   }
   this.parentPath = file.getParent();
   //String configContent = this.readFile(this.getConfigPath());
   String configContent = this.filter(IOUtils.toString(this.getClass().getClassLoader().getResourceAsStream(configFileName)));
   try {
      JSONObject jsonConfig = new JSONObject(configContent);
      this.jsonConfig = jsonConfig;
   } catch (Exception e) {
      this.jsonConfig = null;
   }
}

SpringBoot2.x 整合 Ueditor_java_12

修改getConfigPath()方法的代碼如下：

private String getConfigPath() {
   try {
      //獲取classpath下的config.json路徑
      return this.getClass().getClassLoader().getResource(configFileName).toURI().getPath();
   } catch (URISyntaxException e) {
      return this.parentPath + File.separator + ConfigManager.configFileName;
   }
}

3.6. 設(shè)置圖片在Ueditor中回顯

因?yàn)槲覀儼褕D片存在E盤了，而spring并沒有對E盤目錄進(jìn)行映射。只有按如下所示在application.properties文件加入路徑映射，上傳成功的圖片在Ueditor中才才能回顯：

spring:
  servlet:
    #設(shè)置SpringBoot內(nèi)置tomcat允許上傳圖片的大小
    multipart:
      max-file-size: 100MB
      max-request-size: 1000MB
  #路徑映射，Ueditor上傳圖片成功后回顯用
