关于百度Editor富文本编辑器 自定义上传位置

因为要在网站上编辑富文本数据，所以直接采用百度的富文本编辑器，但是这个编辑器有个缺点，默认情况下，文件只能上传到网站的根目录,不能自定义路径。

而且json配置文件只能和controller.jsp在同一个目录下,不好管理。所以小淘气儿修改了部分源码以及配置了一个拦截器，实现了以上功能。

首先，将下载，并解压的文件夹复制到webapp目录下，如图：

                              

并将ueditor/jsp/下的config.json移动到resources目录下，

config.json是配置图片,文件，视频信息的json格式的文件。以下我就用图片讲解：

/* 前后端通信相关的配置,注释只允许使用多行方式 */
{


    "uploadRoot": "F://javaWeb//UEditor/target/ueditor-1.0-SNAPSHOT/", /*文件上传根目录  */

    ] /* 列出的文件类型 */

}

imageUrlPrefix+imagePathFormat是图片的访问路径，也是图片显示的关键。

uploadRoot是我新增加的键，对应的value是图片上传绝对路径。

正常情况下，在加载ueditor编辑器时，会访问ueditor/jsp/controller.jsp:

controller.jsp代码：

    request.setCharacterEncoding( "utf-8" );
    response.setHeader("Content-Type" , "text/html");
    String rootPath = application.getRealPath( "/" );
    System.out.println(rootPath);
    out.write( new ActionEnter( request, rootPath ).exec() );

  在这里解析的config.json，

  在创建ActionEnter实例的时候，初始化ConfigManager类，其中ConfigManager类是关键。

    private void initEnv() throws FileNotFoundException, IOException {
        File file = new File(this.originalPath);
        if(!file.isAbsolute()) {
            file = new File(file.getAbsolutePath());

    }

    private String filter(String input) {
        return input.replaceAll("/\*[\s\S]*?\*/", "");
    }
}

其中   

    private String getConfigPath() {
        return this.parentPath + File.separator + "config.json";
    }

这方法是拼全config.json的绝对路径，但是parentPath是controller.jsp 的目录路径，所以限制config.json 必须和controller.jsp在同一个目录下。当用spring或者其他代替controller.jsp时，就会找不到这个json文件。

所以这个地方我直接改为

   //修改
    private String getConfigPath() {
        return this.rootPath + File.separator + "WEB-INF" + File.separator + "classes"+File.separator + "config.json";
    }

 当然这个地方您可以随意发挥。

再者，关于上传文件路径配置问题，在源码中下载图片的类是BinaryUploader，

//
// Source code recreated from a .class file by IntelliJ IDEA
// (powered by Fernflower decompiler)
//

package com.baidu.ueditor.upload;

import com.baidu.ueditor.PathFormat;
import com.baidu.ueditor.define.BaseState;
import com.baidu.ueditor.define.FileType;
import com.baidu.ueditor.define.State;
import org.apache.commons.fileupload.FileItemIterator;
import org.apache.commons.fileupload.FileItemStream;
import org.apache.commons.fileupload.FileUploadException;
import org.apache.commons.fileupload.disk.DiskFileItemFactory;
import org.apache.commons.fileupload.servlet.ServletFileUpload;

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 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, 5);
        } else {
            ServletFileUpload upload = new ServletFileUpload(new DiskFileItemFactory());
            if(isAjaxUpload) {
                upload.setHeaderEncoding("UTF-8");
            }

            try {
                for(FileItemIterator e = upload.getItemIterator(request); e.hasNext(); fileStream = null) {
                    fileStream = e.next();
                    if(!fileStream.isFormField()) {
                        break;
                    }
                }

                if(fileStream == null) {
                    return new BaseState(false, 7);
                } else {
                    String savePath = (String)conf.get("savePath");
                    String originFileName = fileStream.getName();
                    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, 8);

                    } else {

                        savePath = PathFormat.parse(savePath, originFileName);
                        String physicalPath = (String)conf.get("rootPath") + savePath;
                        InputStream is = fileStream.openStream();
                        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 var14) {
                return new BaseState(false, 6);
            } catch (IOException var15) {
                return new BaseState(false, 4);
            }
        }
    }

    private static boolean validType(String type, String[] allowTypes) {
        List list = Arrays.asList(allowTypes);
        return list.contains(type);
    }
}

在第64行中，String physicalPath = (String)conf.get("rootPath") + savePath; 就是上传图片最后的路径。其中rootPath是根路径，savePath是自定义的图片保存路径（imagePathFormat对应的值），在源码中rootPath已被限制为网站根目录，所以在这里需要改变为自定义的路径。

其中ConfigManager类中第109，110这里传入的路径字符串，只需将这改为

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

就可以了。

最后，controller.jsp的替代方法：

利用拦截器：

package com.imp.filter;

import com.baidu.ueditor.ActionEnter;

import javax.servlet.*;
import javax.servlet.annotation.WebFilter;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import java.io.IOException;
import java.util.logging.Logger;

/**
 * Created by (IMP)郑和明
 * Date is 2016/12/26
 *
 * UEditor controller.jsp 拦截器
 *
 * 初始化 config,json
 *
 */
@WebFilter(filterName = "UEditorFilter",urlPatterns = "/ueditor/jsp/controller.jsp")
public class UEditorFilter implements Filter {
    private FilterConfig config;

    public void destroy() {

    }

    public void doFilter(ServletRequest req, ServletResponse resp, FilterChain chain) throws ServletException, IOException {

        HttpServletRequest request= (HttpServletRequest) req;
        HttpServletResponse response= (HttpServletResponse) resp;
        request.setCharacterEncoding("utf-8");
        response.setHeader("Content-Type", "text/html");
        String rootPath= config.getServletContext().getRealPath("/");
        Logger.getLogger("imp").info(rootPath);
        String res=new ActionEnter(request, rootPath).exec();
        response.getWriter().write(res);

    }
    public void init(FilterConfig config) throws ServletException {
        this.config=config;
    }

}

或者

String mvc也可以（前提拦截所有jsp请求，然后自定义controller）（代码（略））
