背景
最近工作需要重新搭建公司网站,其中需要使用富文本编辑器,货比三家,最后选择了百度团队的UEditor。项目框架为springboot,所以涉及到springboot集成ueditor,动手之前就听说会有不少坑...上手了发现,emm,果不其然...(主要是上传图片部分)
具体的集成步骤如下,希望这可以帮到看文章的你。
(本人使用的是ueditor-JSP版)
本篇为在修改UEditor源码的情况下集成的UEditor,如果需要不修改UEditor源码的请戳这里

集成步骤:
1 新建springboot项目,添加web和thymeleaf依赖
<?xml version="1.0" encoding="UTF-8"?> <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd"> <modelVersion>4.0.0</modelVersion> <groupId>com.example</groupId> <artifactId>demo</artifactId> <version>0.0.1-SNAPSHOT</version> <packaging>jar</packaging> <name>demo</name> <description>Demo project for Spring Boot</description> <parent> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-parent</artifactId> <version>1.5.9.RELEASE</version> <relativePath/> <!-- lookup parent from repository --> </parent> <properties> <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding> <project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding> <java.version>1.8</java.version> <!--修改thymeleaf版本--> <thymeleaf.version>3.0.3.RELEASE</thymeleaf.version> <thymeleaf-layout-dialect.version>2.1.0</thymeleaf-layout-dialect.version> </properties> <dependencies> <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.springframework.boot</groupId> <artifactId>spring-boot-starter-test</artifactId> <scope>test</scope> </dependency> <build> <plugins> <plugin> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-maven-plugin</artifactId> </plugin> </plugins> </build> </project>
2 下载对应的UEditor源码(完整版或者JSP版本均可):
下载完成后解压至项目的resources/static/
目录下,并将源码中的index.html
复制到templates中,并修改其中引入js的src
<script type="text/javascript" charset="utf-8" src="/ueditor/ueditor.config.js"></script> <script type="text/javascript" charset="utf-8" src="/ueditor/ueditor.all.min.js"> </script> <!--建议手动加在语言,避免在ie下有时因为加载语言失败导致编辑器加载失败--> <!--这里加载的语言文件会覆盖你在配置项目里添加的语言类型,比如你在配置项目里配置的是英文,这里加载的中文,那最后就是中文--> <script type="text/javascript" charset="utf-8" src="/ueditor/lang/zh-cn/zh-cn.js"></script>
注:同时另需要将UEditor中jsp目录下的config.json
复制到项目的resources
根目录下[重要]
注:将完整版源码中的/jsp/src/
下的文件夹复制到项目的src文件夹下 [重要]

3 创建UEditorContorller类,写跳转主页面方法
package com.example.demo.Controller; import ... @Controller public class UEditorController { @RequestMapping("/") private String showPage(){ return "index"; } }
4 运行项目,浏览器地址栏输入
http://localhost:8080/
,进行第一次测试,如果出现以下内容,就可以继续下去啦~第一次测试成功结果.png
此时点击图片上传按钮会显示后台配置项返回格式出错,上传功能将不能正常使用!
接下来就是配置关于图片上传的步骤啦!后端配置项未加载.png
5 引入UEditor相关的依赖
<!--UEditor依赖的jar包 --> <dependency> <groupId>org.json</groupId> <artifactId>json</artifactId> </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>
6 在UEditorController中写入config映射
package com.example.demo.Controller; import ... @Controller public class UEditorController { @RequestMapping("/") private String showPage(){ return "index"; } @RequestMapping(value="/config") public void config(HttpServletRequest request, HttpServletResponse response) { response.setContentType("application/json"); String rootPath = request.getSession().getServletContext().getRealPath("/"); try { String exec = new ActionEnter(request, rootPath).exec(); PrintWriter writer = response.getWriter(); writer.write(exec); writer.flush(); writer.close(); } catch (IOException e) { e.printStackTrace(); } } }
7 修改ConfigManage类的getConfigPath()方法
private String getConfigPath () { //return this.parentPath + File.separator + ConfigManager.configFileName; /*=========手动修改部分=========*/ try{ //获取classpath下的config.json路径 return this.getClass().getClassLoader().getResource("config.json").toURI().getPath(); }catch (URISyntaxException e){ return null; } }
8 配置ueditor.config.js
打开ueditor.config.js
将: , serverUrl: URL + "jsp/controller.jsp"替换为: , serverUrl: "/config"
9 修改BinaryUploader 类,解决其无法获得带字节流的request的问题
打开com.baidu.ueditor.upload.BinaryUploader.java
,修改为:
public class BinaryUploader { 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; //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); } private static boolean validType(String type, String[] allowTypes) { List<String> list = Arrays.asList(allowTypes); return list.contains(type); } }
10 修改图片上传路径
打开config.json
,在其中增加:
“basePath”:“E:/image/”,
打开ConfigManager.java
在 conf.put( "savePath", savePath ); conf.put( "rootPath", this.rootPath ); 上面加一句: conf.put( "basePath", this.jsonConfig.getString("basePath") );
打开BinaryUploader.java
将 String physicalPath = (String) conf.get("rootPath") + savePath; 修改为 String basePath=(String) conf.get("basePath"); String physicalPath = basePath + savePath;
打开application.properties
新增
web.upload-path=E:/ spring.mvc.static-path-pattern=/** spring.resources.static-locations=classpath:/META-INF/resources/,classpath:/resources/,classpath:/static/,classpath:/public/,file:${web.upload-path}
运行项目,发现此时的ueditor的图片上传就可以正常使用了!
配置成功.png
至此,springboot集成ueditor已经结束,希望可以帮到大家。
总结:
此次springboot集成ueditor中,主要遇到的难题就是关于后台config.json的路径配置出错,后来经查找资料发小可以自己手动写一个类来存储该json,不使用其自带的config.json。
