UEditor只提供JSP版本的后端入口代码。但提供了项目源码，因此可以根据业务需求修改源代码。

此处使用了SpringBoot框架，配备了Thymeleaf模板引擎，所以没有必要再添加jsp来兼容UEditor，可通过修改源码满足需要。下面是详细教程。

1.新建SpringBoot项目，添加web和thymeleaf包

pom文件如下:

[html] view plain copy print ?

<? 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 >

                        2.从官网下载源代码并解压至项目，注意config.json我拷到了resources根路径下，如图:
                                import org.springframework.stereotype.Controller;  
                                
import org.springframework.web.bind.annotation.RequestMapping;  
                                
 * Created by ldb on 2017/4/9. 
                                
@Controller  
                                
public class UEditorController {  
                                
    @RequestMapping("/")  
                                
    private String showPage(){  
                                
        return "index";  
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
 * Created by ldb on 2017/4/9.
@Controller
public class UEditorController {
    @RequestMapping("/")
    private String showPage(){
        return "index";
                        4.运行项目。访问路径localhost:8080，跳转到如下界面即是源码已拷贝成功
                        5.此时发现上传图片功能不能用。下面接着看。修改pom，添加UEditor依赖的Jar包。pom文件如下: 
                                [html] view plain copy                                     print?
                                
<?xml version="1.0" encoding=                                    "UTF-8"?>

6.照着源码里的controller.jsp.依样画葫芦，写入UEditorController类，映射路径为config。
                                [java] view plain copy                                     print?

此处需要先转为URI再getPath()，否则如果你的项目路径带空格或者带中文则无法读取到文件

8.运行项目路径http://localhost:8080/config?action=config，如下图显示则表示可读取到config.json文件

9.此时点击上传图片显示如下

提示未找到上传数据。继续一步步debug，发现在BinaryUploader类竟然无法获取到字节流

google得到原因是因为SpringMVC框架对含字节流的request进行了处理，此处传的是处理过的request，故获取不到字节流。此时采用SpringMVC框架的解析器multipartResolver。修改源码如下:

[java] view plain copy print ?

package com.baidu.ueditor.upload;

import com.baidu.ueditor.PathFormat;

import java.io.IOException;

import java.io.InputStream;

import java.util.Arrays;

import java.util.List;

import java.util.Map;

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); import com.baidu.ueditor.PathFormat ; import com.baidu.ueditor.define.AppInfo ; import com.baidu.ueditor.define.BaseState ; import com.baidu.ueditor.define.FileType ; import com.baidu.ueditor.define.State ; import org.apache.commons.fileupload.servlet.ServletFileUpload ; import org.springframework.web.multipart.MultipartFile ; import org.springframework.web.multipart.MultipartHttpServletRequest ; import javax.servlet.http.HttpServletRequest ; import java.io.IOException ; import java.io.InputStream ; import java.util.Arrays ; import java.util.List ; import java.util.Map ; 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) ;

此时进行上传图片，已经能够成功上传了。

无法获取到图片。这是当然的，因为我们把图片存在E盘了，而spring并没有对E盘目录进行映射。此时我们加入路径映射。打开application.properties文件，添加如下代码

[plain] view plain copy print ?

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}

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}复制代码

此时重新运行项目，点击上传图片，图片已经能够正常显示了。

这是怎么回事呢?为什么打成Jar包后就无法上传图片了呢。经过不断的debug和google。。发现了在Jar包里无法以ClassLoader.getResource().getPath()获得的路径读取文件，得用Class类的getResourceAsStream()来读取。具体博文如下:

http://hxraid.iteye.com/blog/483115?page=3#comments

13.那么我们就来修改源码，改成getResourceAsStream读取config.json文件吧。打开ConfigManager类，修改initEnv方法

[java] view plain copy print ?

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( "config.json" )));

try {

JSONObject jsonConfig = new JSONObject( configContent );

this .jsonConfig = jsonConfig;

} catch ( Exception e ) {

this .jsonConfig = null ;

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("config.json")));
			JSONObject jsonConfig = new JSONObject( configContent );
			this.jsonConfig = jsonConfig;
		} catch ( Exception e ) {
			this.jsonConfig = null;
	}复制代码

14. ok了，再次打包，运行项目
