開發環境：一個簡單的web專案中，用百度富文字編輯器 ueditor 實現圖片和檔案的上傳（可自定義上傳路徑）

需要使用到的2個檔案如下（官網上下載）：
1，ueditor-1.4.3.3.zip

2，ueditor1_4_3_3-utf8-jsp.zip

所需jar包：

配置完成後，把解壓原始碼包得到的ueditor-1.4.3.3裡面有一個jsp目錄，進入C:\Users\92307\Desktop\ueditor-1.4.3.3\jsp\src 下，把com資料夾複製C:\Users\dongj\Desktop\百度\ueditor-1.4.3.3\jsp\src 下，把com資料夾複製到專案的java程式碼中：結構如下圖所示。

接下來我將介紹我修改的步驟（以修改上傳圖片路徑為例）：

首先在ConfigManager類中增加一屬性用來存放上傳路徑：

package com.baidu.ueditor;

import java.io.BufferedReader;
import java.io.File;
import java.io.FileInputStream;
import java.io.FileNotFoundException;
import java.io.IOException;
import java.io.InputStreamReader;
import java.io.UnsupportedEncodingException;
import java.util.HashMap;
import java.util.Map;

import org.json.JSONArray;
import org.json.JSONObject;

import com.baidu.ueditor.define.ActionMap;

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

	}

相應的ActionEnter類做如下調整：

package com.baidu.ueditor;

import com.baidu.ueditor.define.ActionMap;
import com.baidu.ueditor.define.AppInfo;
import com.baidu.ueditor.define.BaseState;
import com.baidu.ueditor.define.State;
import com.baidu.ueditor.hunter.FileManager;
import com.baidu.ueditor.hunter.ImageHunter;
import com.baidu.ueditor.upload.Uploader;

import javax.servlet.http.HttpServletRequest;
import java.util.Map;

public class ActionEnter {
	
	private HttpServletRequest request = null;
	
	private String phyPath = null;
	private String rootPath = null;
	private String contextPath = null;
	
	private String actionType = null;
	
	private ConfigManager configManager = null;

	public ActionEnter ( HttpServletRequest request, String rootPath , String phyPath ) {
		
		this.request = request;
		this.phyPath = phyPath;
		this.rootPath = rootPath;
		this.actionType = request.getParameter( "action" );
		this.contextPath = request.getContextPath();
		this.configManager = ConfigManager.getInstance( this.phyPath, this.rootPath, this.contextPath, request.getRequestURI() );
		
	}
	
	public String exec () {
		
		String callbackName = this.request.getParameter("callback");
		
		if ( callbackName != null ) {

			if ( !validCallbackName( callbackName ) ) {
				return new BaseState( false, AppInfo.ILLEGAL ).toJSONString();
			}
			
			return callbackName+"("+this.invoke()+");";
			
		} else {
			return this.invoke();
		}

	}
	
	public String invoke() {
		
		if ( actionType == null || !ActionMap.mapping.containsKey( actionType ) ) {
			return new BaseState( false, AppInfo.INVALID_ACTION ).toJSONString();
		}
		
		if ( this.configManager == null || !this.configManager.valid() ) {
			return new BaseState( false, AppInfo.CONFIG_ERROR ).toJSONString();
		}
		
		State state = null;
		
		int actionCode = ActionMap.getType( this.actionType );
		
		Map<String, Object> conf = null;
		
		switch ( actionCode ) {
		
			case ActionMap.CONFIG:
				return this.configManager.getAllConfig().toString();
				
			case ActionMap.UPLOAD_IMAGE:
			case ActionMap.UPLOAD_SCRAWL:
			case ActionMap.UPLOAD_VIDEO:
			case ActionMap.UPLOAD_FILE:
				conf = this.configManager.getConfig( actionCode );
				state = new Uploader( request, conf ).doExec();
				break;
				
			case ActionMap.CATCH_IMAGE:
				conf = configManager.getConfig( actionCode );
				String[] list = this.request.getParameterValues( (String)conf.get( "fieldName" ) );
				state = new ImageHunter( conf ).capture( list );
				break;
				
			case ActionMap.LIST_IMAGE:
			case ActionMap.LIST_FILE:
				conf = configManager.getConfig( actionCode );
				int start = this.getStartIndex();
				state = new FileManager( conf ).listFile( start );
				break;
				
		}
		
		return state.toJSONString();
		
	}
	
	public int getStartIndex () {
		
		String start = this.request.getParameter( "start" );
		
		try {
			return Integer.parseInt( start );
		} catch ( Exception e ) {
			return 0;
		}
		
	}
	
	/**
	 * callback引數驗證
	 */
	public boolean validCallbackName ( String name ) {
		
		if ( name.matches( "^[a-zA-Z_]+[\\w0-9_]*$" ) ) {
			return true;
		}
		
		return false;
		
	}
	
}

修改BinaryUploader類中的方法：

至此，後端配置已完成。

接下來修改controller.jsp

<%@ page language="java" contentType="text/html; charset=UTF-8"
	import="com.baidu.ueditor.ActionEnter"
    pageEncoding="UTF-8"%>
<%@ page trimDirectiveWhitespaces="true" %>
<%

    request.setCharacterEncoding( "utf-8" );
	response.setHeader("Content-Type" , "text/html");
	
	String physicalPath = "D:\\A";
	String rootPath = application.getRealPath( "/" );

	out.write( new ActionEnter( request, rootPath,physicalPath ).exec() );
	
%>

其中physicalPath為上傳資源路徑。

修改config.json如下：

其中imageUrlPrefix為tomcat虛擬路徑訪問地址。

注：如果不設定虛擬路徑，並配上地址本專案將無法顯示圖片（可在tomcat上配），具體設定方法請自行百度。

至此，專案配置完成。可執行！

由於個人能力有限，文筆不太好。如有問題請不吝賜教。
