下載UEditor

https://ueditor.baidu.com/website/download.html

下載完整源碼和JSP版本

Spring后端集成

1. 解壓完整源碼，拷貝jsp目錄下的java源碼，到spring mvc后端

3. 項目常量配置文件新建upload.properties，也放在resouce目錄下，文件內容如下：

#host地址
host=http://localhost:8081/ssm_project
#文件上傳服務器地址（ip+端口）
uploadHost=http://localhost:8090/
#普通圖片上傳保存目錄
imagePath = fileUpload/image/
#系統用戶頭像上傳保存目錄
headImgPath = fileUpload/image/headImg/
#系統用戶默認頭像
sysUserDefImg = sysUser-default.jpg
#文本文件上傳保存目錄
documentPath = fileUpload/document/
#音頻文件上傳保存目錄
soundPath = fileUpload/sound/
#視頻文件上傳保存目錄
videoPath = fileUpload/video/
#ueditor編輯器上傳文件保存目錄（包括圖片、視頻、音頻、文本等文件）
ueditor = fileUpload/ueditor/

將upload.properties添加到Spring啟動配置文件application.xml中，以便后面Controller訪問

<!-- 引入數據庫配置文件 -->
<bean id="configProperties" class="org.springframework.beans.factory.config.PropertiesFactoryBean">
  <property name="locations">
    <list>
      <value>classpath:config.properties</value>
      <value>classpath:redis.properties</value>
      <value>classpath:upload.properties</value>
    </list>
  </property>
</bean>

4. 編寫工具類UploadUtil.java

package cn.lega.common.util;

import com.sun.jersey.api.client.Client;
import com.sun.jersey.api.client.WebResource;
import org.apache.commons.io.FilenameUtils;
import org.springframework.util.FileCopyUtils;
import org.springframework.web.multipart.MultipartFile;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import java.io.File;
import java.io.IOException;
import java.text.SimpleDateFormat;
import java.util.Date;
import java.util.UUID;

public class UploadUtil {
  /**
   * 上傳文件
   *
   * @param request
   * @param response
   * @param serverPath 服務器地址:(http://172.16.5.102:8090/)
   * @param path    文件路徑（不包含服務器地址：upload/）
   * @return
   */
  public static String upload(Client client, MultipartFile file, HttpServletRequest request, HttpServletResponse response, String serverPath, String path) {
    // 文件名稱生成策略（日期時間+uuid ）
    UUID uuid = UUID.randomUUID();
    Date d = new Date();
    SimpleDateFormat format = new SimpleDateFormat("yyyyMMddHHmmss");
    String formatDate = format.format(d);
    // 獲取文件的擴展名
    String extension = FilenameUtils.getExtension(file.getOriginalFilename());
    // 文件名
    String fileName = formatDate + "-" + uuid + "." + extension;
    //相對路徑
    String relaPath = path + fileName;

//    String a = serverPath + path.substring(0, path.lastIndexOf("/"));
//    File file2 = new File(a);
//    if (!file2.exists()) {
//      boolean mkdirs = file2.mkdirs();
//      System.out.println(mkdirs);
//    }

    // 另一臺tomcat的URL（真實路徑）
    String realPath = serverPath + relaPath;
    // 設置請求路徑
//    WebResource resource = client.resource(realPath);

    // 發送開始post get put（基于put提交）
//    try {
//      resource.put(String.class, file.getBytes());
//      return fileName + ";" + relaPath + ";" + realPath;
//    } catch (IOException e) {
//      e.printStackTrace();
//      return "";
//    }

    // 用戶目錄/root/fileUpload/ueditor
    String userDir = System.getProperty("user.home");
    String ueditorUploadPath = userDir + File.separator + path;
    File file2 = new File(ueditorUploadPath);
    if (!file2.exists()) {
      file2.mkdirs();
    }
    String newFilePath = ueditorUploadPath + fileName;

    // 保存在本地
    File file3 = new File(newFilePath);
    try {
      FileCopyUtils.copy(file.getBytes(), file3);
      return fileName + ";" + relaPath + ";" + realPath;
    } catch (IOException e) {
      e.printStackTrace();
      return "";
    }
  }

  public static String delete(String filePath) {
    try {
      Client client = new Client();
      WebResource resource = client.resource(filePath);
      resource.delete();
      return "y";
    } catch (Exception e) {
      e.printStackTrace();
      return "n";
    }
  }
}

5. 編寫Controller類UeditorController.java，為前端提供上傳接口

package cn.lega.common.controller;

import cn.lega.common.baidu.ueditor.ActionEnter;
import cn.lega.common.util.ResponseUtils;
import cn.lega.common.util.StrUtils;
import cn.lega.common.util.UploadUtil;
import cn.lega.common.web.BaseController;
import com.alibaba.fastjson.JSON;
import com.alibaba.fastjson.JSONObject;
import com.sun.jersey.api.client.Client;
import org.apache.commons.io.FilenameUtils;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.core.io.ClassPathResource;
import org.springframework.web.bind.annotation.*;
import org.springframework.web.multipart.MultipartFile;
import org.springframework.web.multipart.MultipartHttpServletRequest;
import org.springframework.web.multipart.MultipartResolver;
import org.springframework.web.multipart.commons.CommonsMultipartResolver;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import java.io.*;
import java.util.Map;

/**
 * 用于處理關于ueditor插件相關的請求
 *
 * @author silianpan
 */
@RestController
@CrossOrigin
@RequestMapping("/common/ueditor")
public class UeditorController extends BaseController {

  // 后臺圖片保存地址
  @Value("#{configProperties['ueditor']}")
  private String ueditor;

  @Value("#{configProperties['uploadHost']}")
  private String uploadHost;  //項目host路徑

  /**
   * ueditor文件上傳（上傳到外部服務器）
   *
   * @param request
   * @param response
   * @param action
   */
  @ResponseBody
  @RequestMapping(value = "/ueditorUpload.do", method = {RequestMethod.GET, RequestMethod.POST})
  public void editorUpload(HttpServletRequest request, HttpServletResponse response, String action) {
    response.setContentType("application/json");
    String rootPath = request.getSession().getServletContext().getRealPath("/");

    try {
      if ("config".equals(action)) {  // 如果是初始化
        String exec = new ActionEnter(request, rootPath).exec();
        PrintWriter writer = response.getWriter();
        writer.write(exec);
        writer.flush();
        writer.close();
      } else if ("uploadimage".equals(action) || "uploadvideo".equals(action) || "uploadfile".equals(action)) {  // 如果是上傳圖片、視頻、和其他文件
        try {
          MultipartResolver resolver = new CommonsMultipartResolver(request.getSession().getServletContext());
          MultipartHttpServletRequest Murequest = resolver.resolveMultipart(request);
          Map<String, MultipartFile> files = Murequest.getFileMap();// 得到文件map對象
          // 實例化一個jersey
          Client client = new Client();

          for (MultipartFile pic : files.values()) {
            JSONObject jo = new JSONObject();
            long size = pic.getSize();  // 文件大小
            String originalFilename = pic.getOriginalFilename(); // 原來的文件名
            if (StrUtils.isEmpty(uploadHost) || uploadHost.equals("default")) {
              uploadHost = System.getProperty("user.home") + File.separator;
            }
            String uploadInfo = UploadUtil.upload(client, pic, request, response, uploadHost, ueditor);
            if (!"".equals(uploadInfo)) {  // 如果上傳成功
              String[] infoList = uploadInfo.split(";");
              jo.put("state", "SUCCESS");
              jo.put("original", originalFilename);//原來的文件名
              jo.put("size", size); // 文件大小
              jo.put("title", infoList[1]); // 隨意，代表的是鼠標經過圖片時顯示的文字
              jo.put("type", FilenameUtils.getExtension(pic.getOriginalFilename())); // 文件后綴名
              jo.put("url", infoList[2]);// 這里的url字段表示的是上傳后的圖片在圖片服務器的完整地址（http://ip:端口/***/***/***.jpg）
            } else {  // 如果上傳失敗
            }
            ResponseUtils.renderJson(response, jo.toString());
          }
        } catch (Exception e) {
          e.printStackTrace();
        }
      }
    } catch (Exception e) {
    }
  }

//  @RequestMapping(value = "/exec")
//  public void config(HttpServletRequest request, HttpServletResponse response) {
//    // response.setContentType("application/json");
//    String rootPath = request.getSession().getServletContext().getRealPath("/");
//    response.setHeader("Content-Type" , "text/html");
//    try {

//  }

  @RequestMapping(value = "/exec")
  @ResponseBody
  public String exec(HttpServletRequest request) throws UnsupportedEncodingException {
    request.setCharacterEncoding("utf-8");
    String rootPath = request.getSession().getServletContext().getRealPath("/");
    return new ActionEnter(request, rootPath).exec();
  }

  @RequestMapping("/ueconfig")
  public void getUEConfig(HttpServletRequest request, HttpServletResponse response) {
    org.springframework.core.io.Resource res = new ClassPathResource("ueditorConfig.json");
    InputStream is = null;

    }
  }
}

Vue前端集成

1. 解壓jsp版本，拷貝到Vue前端項目static目錄中

Spring+Vue整合UEditor富文本實現圖片附件上傳的方法

2. 前端常量配置

// 靜態目錄
export const STATIC_PATH = process.env.NODE_ENV === 'production' ? './static/' : '/static/'
// UEditor服務路徑，對應UeditorController.java上傳接口
export const UEDITOR_SERVER = API_BASEURL + '/common/ueditor/ueditorUpload.do'

3. 安裝插件vue-ueditor-wrap

npm install vue-ueditor-wrap
or
yarn add vue-ueditor-wrap

4. 編寫組件

<template>
  <div>
    <component
      
      :is="currentViewComp"
      transition="fade"
      transition-mode="out-in"
      :config="ueditorConfig"
      v-model="formData[item.prop]"
      :destroy="true"
      @ready="ueReady">
    </component>
  </div>
</template>
<script>
import VueUeditorWrap from 'vue-ueditor-wrap'
import { STATIC_PATH, UEDITOR_SERVER } from '@/config'
export default {
data() {
  return {
   currentViewComp: null,
   ueditorConfig: {
    serverUrl: UEDITOR_SERVER,
    UEDITOR_HOME_URL: STATIC_PATH + 'ueditor1_4_3_3/',
    initialContent: '',
    initialFrameHeight: 400,
    initialFrameWidth: '100%',
    autoHeightEnabled: false
   }
  }
 },
 mounted() {
  this.currentViewComp = VueUeditorWrap
 },
 destroyed() {
  this.currentViewComp = null
 },
 methods: {
  ueReady(editorInstance) {
   this.$nextTick(() => {
    editorInstance.setContent('')
   })
  }
 }
}
</script>

至此，大功告成~
