一、基礎(chǔ)準備
1. 創(chuàng)建項目并引入依賴
boot-ueditor
<parent>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-parent</artifactId>
<version>2.5.4</version>
<relativePath/> <!-- lookup parent from repository -->
</parent>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
</dependency>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-thymeleaf</artifactId>
</dependency>
<dependency>
<groupId>org.json</groupId>
<artifactId>json</artifactId>
<version>20190722</version>
</dependency>
<dependency>
<groupId>commons-fileupload</groupId>
<artifactId>commons-fileupload</artifactId>
<version>1.3.2</version>
</dependency>
<dependency>
<groupId>commons-codec</groupId>
<artifactId>commons-codec</artifactId>
<version>1.9</version>
</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)制到項目Java目錄下面
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??
二、靜態(tài)頁面+控制層
在??resources???目錄下面創(chuàng)建??templates??

System.out.println("doGet");

}
}
三、配置調(diào)整
3.1. 圖片大小
當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
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：
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
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";
- 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);
- 修改initEnv()方法
為了讓項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;
}
}
- 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
因為我們把圖片存在E盤了，而spring并沒有對E盤目錄進行映射。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
