Spring+Vue整合UEditor富文本实现图片附件上传的方法
-UEditor
https://ueditor.baidu.com/website/download.html
-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
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 requejibVXGGZoOst, 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
// 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");
// String rootPath = request.getSession().getServletContext().getRealPath("/");
// response.setHeader("Content-Type" , "text/html");

// }
// }
@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;
response.setHeader("Content-Type", "text/html");
try {
is = new FileInputStream(res.getFile());
StringBuffer sb = new StringBuffer();
byte[] b = new byte[1024];
int length = 0;
while (-1 != (length = is.read(b))) {
sb.append(new String(b, 0, length, "utf-8"));
}
String result = sb.toString().replaceAll("/\\*(.|[\\r\\n])*?\\*/", "");
JSONObject json = JSON.parseObject(result);
PrintWriter out = response.getWriter();
out.print(json.toString());
} catch (IOException e) {
e.printStackTrace();
} finally {
try {
is.close();
} catch (IOException e) {
e.printStackTrace();
}
}
}
}
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
style="width:100%!important" :is="currentViewComp" transition="fade" transition-mode="out-in" :config="ueditorConfig" v-model="formData[item.prop]" :destroy="true" @ready="ueReady">
style="width:100%!important"
:is="currentViewComp"
transition="fade"
transition-mode="out-in"
:config="ueditorConfig"
v-model="formData[item.prop]"
:destroy="true"
@ready="ueReady">
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('')
})
}
}
}
至此,大功告成~
