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:

<?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>ueditor-test</artifactId>
	<version>0.0.1-SNAPSHOT</version>
	<packaging>jar</packaging>
 
	<name>ueditor-test</name>
	<description>Demo project for Spring Boot</description>
 
	<parent>
		<groupId>org.springframework.boot</groupId>
		<artifactId>spring-boot-starter-parent</artifactId>
		<version>1.5.2.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>
	</dependencies>
 
	<build>
		<plugins>
			<plugin>
				<groupId>org.springframework.boot</groupId>
				<artifactId>spring-boot-maven-plugin</artifactId>
			</plugin>
		</plugins>
	</build>
 
 
</project>

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:

3.添加UEditorController，跳转到index页面:

package com.example;
 
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: 

<?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"

	</parent>
 
	<properties>

		<java.version>1.8</java.version>
		<thymeleaf.version>3.0.3.RELEASE</thymeleaf.version>
		<thymeleaf-layout-dialect.version>2.1.0</thymeleaf-layout-dialect.version>
	</properties>
 
	<dependencies>

                    </plugin>
                </plugins>
            </build>
 
 
        </project>

6.照着源码里的controller.jsp.依样画葫芦，写入UEditorController类，映射路径为config。

package com.example;

import com.baidu.ueditor.ActionEnter;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import java.io.IOException;
import java.io.PrintWriter;

/**
* Created by ldb on 2017/4/9.
*/
@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();
       }

   }
}

7.一步一步debug，发现无法加载config.json文件。此时修改ConfigManage类的getConfigPath()方法。如下:

package com.baidu.ueditor;

import com.baidu.ueditor.define.ActionMap;
import org.json.JSONArray;
import org.json.JSONObject;

import java.io.*;
import java.net.URISyntaxException;
import java.util.HashMap;
import java.util.Map;

/**
* 配置管理器
* @author hancong03@baidu.com
*
*/
public final class ConfigManager {

private final String rootPath;
private final String originalPath;
private final String contextPath;
private static final String configFileName = "config.json";
private String parentPath = null;
private JSONObject jsonConfig = null;
// 涂鸦上传filename定义
private final static String SCRAWL_FILE_NAME = "scrawl";
// 远程图片抓取filename定义
private final static String REMOTE_FILE_NAME = "remote";

/*
* 通过一个给定的路径构建一个配置管理器， 该管理器要求地址路径所在目录下必须存在config.properties文件
*/
private ConfigManager ( String rootPath, String contextPath, String uri ) throws FileNotFoundException, IOException {

rootPath = rootPath.replace( "\\", "/" );

this.rootPath = rootPath;
this.contextPath = contextPath;

if ( contextPath.length() > 0 ) {
this.originalPath = this.rootPath + uri.substring( contextPath.length() );
} else {
this.originalPath = this.rootPath + uri;
}

this.initEnv();

}

/**
* 配置管理器构造工厂
* @param rootPath 服务器根路径
* @param contextPath 服务器所在项目路径
* @param uri 当前访问的uri
* @return 配置管理器实例或者null
*/
public static ConfigManager getInstance ( String rootPath, String contextPath, String uri ) {

try {
return new ConfigManager(rootPath, contextPath, uri);
} catch ( Exception e ) {
return null;
}

}

// 验证配置文件加载是否正确
public boolean valid () {
return this.jsonConfig != null;
}

public JSONObject getAllConfig () {

return this.jsonConfig;

}

public Map<String, Object> getConfig ( int type ) {

Map<String, Object> conf = new HashMap<String, Object>();
String savePath = null;

switch ( type ) {

case ActionMap.UPLOAD_FILE:
conf.put( "isBase64", "false" );
conf.put( "maxSize", this.jsonConfig.getLong( "fileMaxSize" ) );
conf.put( "allowFiles", this.getArray( "fileAllowFiles" ) );
conf.put( "fieldName", this.jsonConfig.getString( "fileFieldName" ) );
savePath = this.jsonConfig.getString( "filePathFormat" );
break;

case ActionMap.UPLOAD_IMAGE:
conf.put( "isBase64", "false" );
conf.put( "maxSize", this.jsonConfig.getLong( "imageMaxSize" ) );
conf.put( "allowFiles", this.getArray( "imageAllowFiles" ) );
conf.put( "fieldName", this.jsonConfig.getString( "imageFieldName" ) );
savePath = this.jsonConfig.getString( "imagePathFormat" );
break;

case ActionMap.UPLOAD_VIDEO:
conf.put( "maxSize", this.jsonConfig.getLong( "videoMaxSize" ) );
conf.put( "allowFiles", this.getArray( "videoAllowFiles" ) );
conf.put( "fieldName", this.jsonConfig.getString( "videoFieldName" ) );
savePath = this.jsonConfig.getString( "videoPathFormat" );
break;

case ActionMap.UPLOAD_SCRAWL:
conf.put( "filename", ConfigManager.SCRAWL_FILE_NAME );
conf.put( "maxSize", this.jsonConfig.getLong( "scrawlMaxSize" ) );
conf.put( "fieldName", this.jsonConfig.getString( "scrawlFieldName" ) );
conf.put( "isBase64", "true" );
savePath = this.jsonConfig.getString( "scrawlPathFormat" );
break;

case ActionMap.CATCH_IMAGE:
conf.put( "filename", ConfigManager.REMOTE_FILE_NAME );
conf.put( "filter", this.getArray( "catcherLocalDomain" ) );
conf.put( "maxSize", this.jsonConfig.getLong( "catcherMaxSize" ) );
conf.put( "allowFiles", this.getArray( "catcherAllowFiles" ) );
conf.put( "fieldName", this.jsonConfig.getString( "catcherFieldName" ) + "[]" );
savePath = this.jsonConfig.getString( "catcherPathFormat" );
break;

case ActionMap.LIST_IMAGE:
conf.put( "allowFiles", this.getArray( "imageManagerAllowFiles" ) );
conf.put( "dir", this.jsonConfig.getString( "imageManagerListPath" ) );
conf.put( "count", this.jsonConfig.getInt( "imageManagerListSize" ) );
break;

case ActionMap.LIST_FILE:
conf.put( "allowFiles", this.getArray( "fileManagerAllowFiles" ) );
conf.put( "dir", this.jsonConfig.getString( "fileManagerListPath" ) );
conf.put( "count", this.jsonConfig.getInt( "fileManagerListSize" ) );
break;

}

conf.put( "savePath", savePath );
conf.put( "rootPath", this.rootPath );

return conf;

}

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() );

try{
JSONObject jsonConfig = new JSONObject( configContent );
this.jsonConfig = jsonConfig;
} catch ( Exception e ) {
this.jsonConfig = null;
}

}


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

private String[] getArray ( String key ) {

JSONArray jsonArray = this.jsonConfig.getJSONArray( key );
String[] result = new String[ jsonArray.length() ];

for ( int i = 0, len = jsonArray.length(); i < len; i++ ) {
result[i] = jsonArray.getString( i );
}

return result;

}

private String readFile ( String path ) throws IOException {

StringBuilder builder = new StringBuilder();

try {

InputStreamReader reader = new InputStreamReader( new FileInputStream( path ), "UTF-8" );
BufferedReader bfReader = new BufferedReader( reader );

String tmpContent = null;

while ( ( tmpContent = bfReader.readLine() ) != null ) {
builder.append( tmpContent );
}

bfReader.close();

} catch ( UnsupportedEncodingException e ) {
// 忽略
}

return this.filter( builder.toString() );

}

// 过滤输入字符串, 剔除多行注释以及替换掉反斜杠
private String filter ( String input ) {

return input.replaceAll( "/\\*[\\s\\S]*?\\*/", "" );

}

}

this.getClass().getClassLoader().getResource("config.json").toURI().getPath(); 
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:

package com.baidu.ueditor.upload;
 
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。

10.可是图片究竟上传到哪里了呢?继续一步步debug发现，上传到如图路径

如图路径为tomcat缓存路径，只要重启下tomcat该文件就会被删除。我们需要将其存储到磁盘中。此时修改config.json文件。

红色箭头为修改处。我需要将文件存储到E:/image/**下，此处我多添加了basePath，是想把视频、音乐等静态资源都存储到E盘。由于添加了basePath，需要修改配置。通过debug来到ConfigManage

添加红色箭头代码，将basePath塞进配置文件里。之后继续来到上传文件类BinaryUploader，修改如下代码:

运行项目，点击添加图片。打开E盘的image目录，如图，成功上传到E盘对应路径

11.打开浏览器，发现页面无法加载图片。如下图:

打开浏览器调试器。如图

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

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}

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。

12.至此，SpringBoot整合UEditor应该完了吧。别急，SpringBoot主张打包成Jar包运行，我们用Maven来打包运行试试

java -jar 

打开项目地址，点击上传图片，发现竟然上传不了了??!!

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

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;
}

}

14. ok了，再次打包，运行项目

成功了!!!
