SpringVue整合UEditor富文本实现图片附件上传

下载 UEditor

https://ueditor.baidu.com/web…

下载完整源码和 JSP 版本

Spring 后端集成

1. 解压完整源码，拷贝 jsp 目录下的 java 源码，到 spring mvc 后端

jsp 目录下 java 源码

集成 spring mvc 后端

2. 配置 config.json

• 解压 JSP 版本
• 拷贝 jsp 目录下 config.json

• 放到 java 项目的 resource 目录下，在这里是 ueditorConfig.json

• 配置 config.json 文件名称，这里是 ueditorConfig.json

3. 项目常量配置文件

• 新建 upload.properties，也放在 resouce 目录下，文件内容如下：

#host 地址
host=http://localhost:8081/ssm_project
#文件上传服务器地址（ip+ 端口）uploadHost=http://localhost:8090/
#普通图片上传保存目录
imagePath = fileUpload/image/
#系统用户头像上传保存目录
headImgPath = fileUpload/image/headImg/
#系统用户默认头像
sysUserDefImg = sysUser-default.jpg
#文本文件上传保存目录
documentPath = fileUpload/document/
#音频文件上传保存目录
soundPath = fileUpload/sound/
#视频文件上传保存目录
videoPath = fileUpload/video/
#ueditor 编辑器上传文件保存目录（包括图片、视频、音频、文本等文件）ueditor = fileUpload/ueditor/

• 将 upload.properties 添加到 Spring 启动配置文件 application.xml 中，以便后面 Controller 访问

<!-- 引入数据库配置文件 -->
<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. 编写工具类 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 {
    /**
     * 上传文件
     *
     * @param request
     * @param response
     * @param serverPath 服务器地址:(http://172.16.5.102:8090/)
     * @param path       文件路径（不包含服务器地址：upload/）* @return
     */
    public static String upload(Client client, MultipartFile file, HttpServletRequest request, HttpServletResponse response, String serverPath, String path) {
        // 文件名称生成策略（日期时间 +uuid）UUID uuid = UUID.randomUUID();
        Date d = new Date();
        SimpleDateFormat format = new SimpleDateFormat("yyyyMMddHHmmss");
        String formatDate = format.format(d);
        // 获取文件的扩展名
        String extension = FilenameUtils.getExtension(file.getOriginalFilename());
        // 文件名
        String fileName = formatDate + "-" + uuid + "." + extension;
        // 相对路径
        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);
//        }

        // 另一台 tomcat 的 URL（真实路径）String realPath = serverPath + relaPath;
        // 设置请求路径
//        WebResource resource = client.resource(realPath);

        // 发送开始 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 "";
//        }

        // 用户目录 /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. 编写 Controller 类 UeditorController.java，为前端提供上传接口

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;

/**
 * 用于处理关于 ueditor 插件相关的请求
 *
 * @author silianpan
 */
@RestController
@CrossOrigin
@RequestMapping("/common/ueditor")
public class UeditorController extends BaseController {

    // 后台图片保存地址
    @Value("#{configProperties['ueditor']}")
    private String ueditor;

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

    /**
     * ueditor 文件上传（上传到外部服务器）*
     * @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)) {    // 如果是上传图片、视频、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 对象
                    // 实例化一个 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();  // 原来的文件名
                        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)) {    // 如果上传成功
                            String[] infoList = uploadInfo.split(";");
                            jo.put("state", "SUCCESS");
                            jo.put("original", originalFilename);// 原来的文件名
                            jo.put("size", size); // 文件大小
                            jo.put("title", infoList[1]); // 随意，代表的是鼠标经过图片时显示的文字
                            jo.put("type", FilenameUtils.getExtension(pic.getOriginalFilename())); // 文件后缀名
                            jo.put("url", infoList[2]);// 这里的 url 字段表示的是上传后的图片在图片服务器的完整地址（http://ip: 端口 /***/***/***.jpg）} else {// 如果上传失败}
                        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");

    @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");

}

Vue 前端集成

1. 解压 jsp 版本，拷贝到 Vue 前端项目 static 目录中

2. 前端常量配置

// 静态目录
export const STATIC_PATH = process.env.NODE_ENV === 'production' ? './static/' : '/static/'
// UEditor 服务路径，对应 UeditorController.java 上传接口
export const UEDITOR_SERVER = API_BASEURL + '/common/ueditor/ueditorUpload.do'

3. 安装插件 vue-ueditor-wrap

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

4. 编写组件

<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>

至此，大功告成~
