Spring+Vue整合UEditor富文本實現圖片附件上傳

下載UEditor

https://ueditor.baidu.com/web...

下載完整源碼和JSP版本

Spring後端集成

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

jsp目錄下java源碼

集成spring mvc後端

2. 配置config.json

• 解壓JSP版本
• 拷貝jsp目錄下config.json

• 放到java項目的resource目錄下，在這裏是ueditorConfig.json

• 配置config.json文件名稱，這裏是ueditorConfig.json

3. 項目常量配置文件

• 新建upload.properties，也放在resouce目錄下，文件內容以下：

#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啓動配置文件application.xml中，以便後面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);
//        }

        // 另外一臺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（基於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，爲前端提供上傳接口

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.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;

/**

@RestController
@CrossOrigin
@RequestMapping("/common/ueditor")
public class UeditorController extends BaseController {

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

    private String uploadHost;    //項目host路徑

    /**

                String exec = new ActionEnter(request, rootPath).exec();
                PrintWriter writer = response.getWriter();
                writer.write(exec);

                    Map<String, MultipartFile> files = Murequest.getFileMap();// 獲得文件map對象
                    // 實例化一個jersey
                    Client client = new Client();

                        if (!"".equals(uploadInfo)) {    // 若是上傳成功
                            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，表明的是鼠標通過圖片時顯示的文字

}

Vue前端集成

1. 解壓jsp版本，拷貝到Vue前端項目static目錄中

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
            style="width:100%!important"
            :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>

Tomcat文件服務

配置tomcat/conf/server.xml，添加以下代碼

port=8090 文件訪問服務端口
docBase="/home/" 文件存儲目錄

<Service name="fileUpload">
  <!--分配8089端口 -->
  <!-- <Connector port="8090" protocol="HTTP/1.1" connectionTimeout="20000" URIEncoding="GBK" redirectPort="8443" /> -->
  <Connector port="8090" protocol="HTTP/1.1" connectionTimeout="20000" redirectPort="8443" />
    <Engine name="fileUpload" defaultHost="localhost">
    <!--name爲項目訪問地址 此配置的訪問爲http://localhost:8080 appBase配置tomcat下wabapps下的路徑-->
    <Host name="localhost" appBase="webapps"
      unpackWARs="true" autoDeploy="true" xmlValidation="false" xmlNamespaceAware="false">
      <!--資源地址-->
      <Context path="" docBase="/home/" debug="0" reloadable="false"/>
    </Host>
  </Engine>
 </Service>

至此，大功告成~
