百度富文本图片上传路径配置(非项目路径)

一、前言

在项目中使用了百度富文本，发现图片上传的路径是项目的路径，但是现在要求将图片存储在项目之外的地方，如D:/ 盘等，按照API配置貌似无法做到这个要求，那么就需要稍微修改源码了，以下是本人解决方案，仅供参考

二、解决方案

前提是已经引入百度富文本，并且能够正常使用，若还无法正常使用，请阅读API

第一步：新建ActionEnterPlugs 并继承ActionEnter（com.baidu.ueditor包内）

import com.baidu.ueditor.ActionEnter;
import com.baidu.ueditor.ConfigManager;
import com.baidu.ueditor.define.ActionMap;
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 java.util.Map;
import javax.servlet.http.HttpServletRequest;

/**

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

    //图片存储路径
    private String saveRootPath;
    public ActionEnterPlugs(HttpServletRequest request, String rootPath,String saveRootPath){
        super(request,rootPath);
        this.request = request;
        this.rootPath = rootPath;
        this.actionType = request.getParameter("action");
        this.contextPath = request.getContextPath();
        this.configManager = ConfigManager.getInstance(this.rootPath, this.contextPath, request.getRequestURI());
        this.saveRootPath = saveRootPath;
    }
    @Override
    public String invoke() {
        if(this.actionType != null && ActionMap.mapping.containsKey(this.actionType)) {
            if(this.configManager != null && this.configManager.valid()) {
                State state = null;
                int actionCode = ActionMap.getType(this.actionType);
                Map conf = null;
                switch(actionCode) {
                    case 0:
                        return this.configManager.getAllConfig().toString();
                    case 1:
                    case 2:
                    case 3:
                    case 4:
                        conf = this.configManager.getConfig(actionCode);
                        //重点,这里修改了图片的存储路径
                        conf.put("rootPath",this.saveRootPath);
                        state = (new Uploader(this.request, conf)).doExec();
                        break;
                    case 5:
                        conf = this.configManager.getConfig(actionCode);
                        //重点,这里修改了图片的存储路径
                        conf.put("rootPath",this.saveRootPath);
                        String[] list = this.request.getParameterValues((String)conf.get("fieldName"));
                        state = (new ImageHunter(conf)).capture(list);
                        break;
                    case 6:
                    case 7:
                        conf = this.configManager.getConfig(actionCode);
                        //重点,这里修改了图片的存储路径
                        conf.put("rootPath",this.saveRootPath);
                        int start = this.getStartIndex();
                        state = (new FileManager(conf)).listFile(start);
                }

                return state.toJSONString();
            } else {
                return (new BaseState(false, 102)).toJSONString();
            }
        } else {
            return (new BaseState(false, 101)).toJSONString();
        }
    }
}

第二步：找到controller.jsp文件，并修改为

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

    request.setCharacterEncoding( "utf-8" );
	response.setHeader("Content-Type" , "text/html");
	
	String rootPath = application.getRealPath( "/" );
	//文件存储路径，可以读取配置文件
	String saveRootPath = PropertiesFileUtil.getInstance().get("SYSTEM_UPLOAD_IMAGE");
	//获取图片路径前缀，可以读取配置文件
	//String getFilePath = PropertiesFileUtil.getInstance().get("SYSTEM_DOWN_IMAGE");
	String action = request.getParameter("action");
	//重点在这里，使用ActionEnterPlugs我们刚在新建的类
	String result = new ActionEnterPlugs( request, rootPath ,saveRootPath).exec();
	if( action!=null && (action.equals("listfile") || action.equals("listimage") ) ){

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

		result = result.replaceAll(saveRootPath, "/");

	}
	//result = result.replaceAll("/file",getFilePath);
	out.write( result );

%>

到此已经修改完毕，现在图片已经存储在你配置文件中配置的存储路径。
