一、前言

在使用spring boot做后台系统，vue做前端系统，给客户开发一套系统时候，其中用到了图片上传和显示的功能。

二、环境

• 前端：vue
• 前端组件：tinymce
• 后台：spring boot:2.2.3

三、正文

在客户开发一套门户管理系统时，集成了tinymce组件，用于编辑内容，springboot不同于其他项目。
是集成tomcat的，文件和图片是不能直接访问的。所以我在做集成富文本编辑器时，需要处理图片的问题。
这个问题跟上传头像等显示图片的功能是类似的。下面记录详情步骤代码。

第一步：集成tinymce组件

<!--引入tinymce组件-->import Tinymce from '@/components/Tinymce'<!--启用tinymce组件--><el-form-item> <el-button type="primary" :loading="btnLoading" @click="onSubmit" >保 存</el-button></el-form-item><!--核心代码--><template> <div class="page-container"> <div class="page-title-section"> </div> <div class="page-content-section"> <div class="page-content-form"> <el-form ref="dataForm" :model="formData" :rules="formRules" label-width="180px"> <el-form-item> <div> <tinymce v-model="formData.content" :height="300" /> </div> </el-form-item> <el-form-item> <el-button type="primary" :loading="btnLoading" @click="onSubmit" >保 存</el-button> </el-form-item> </el-form> </div> </div> </div></template><script>import Tinymce from '@/components/Tinymce'export default { name:"contentEdit", components: {Tinymce}, data(){ return{ formData:{ content:'', }, } }, created() { }, mounted() {}, activated() {}, deactivated() {}, methods:{ //表单提交 onSubmit(){ this.$refs['dataForm'].validate((valid) => { if (valid) { this.btnLoading = true this.$axios({ url: this.formData.id == '' ? '/products/save' : '/products/edit', method: 'POST', params: this.formData }).then(res => { //处理成功回调 const{ state,result , errmsg} = res.data if( state && state == 1 ){ this.$message.success('操作成功'); this.$router.push( {path:'/products/list'} ) }else{ return this.$message.error(errmsg || '操作失败'); } }).finally(() => { this.btnLoading = false }) } }) },</script><!--Tinymce初始化代码-->initTinymce() { const _this = this window.tinymce.init({ selector: `#${this.tinymceId}`, language: this.languageTypeList['en'], height: this.height, body_class: 'panel-body ', object_resizing: false, toolbar: this.toolbar.length > 0 ? this.toolbar : toolbar, menubar: this.menubar, plugins: plugins, end_container_on_empty_block: true, powerpaste_word_import: 'clean', code_dialog_height: 450, code_dialog_width: 1000, advlist_bullet_styles: 'square', advlist_number_styles: 'default', imagetools_cors_hosts: ['mand('mceFullScreen') } if (tinymce) { tinymce.destroy() } }, setContent(value) { window.tinymce.get(this.tinymceId).setContent(value) }, getContent() { window.tinymce.get(this.tinymceId).getContent() }, imageSuccessCBK(arr) { const _this = this arr.forEach(v => { window.tinymce.get(_this.tinymceId).insertContent(`<img class="wscnph" src="${v.url}" >`) }) } }

第二步：后台代码

@RequestMapping(value = "/imageUpload", method = RequestMethod.POST) public void imageUpload(@RequestParam("file") MultipartFile file, HttpServletRequest request, HttpServletResponse response) { try { logger.info("上传图片名 :" + file.getOriginalFilename()); if (!file.isEmpty()) {// Properties p = new Properties();// 属性集合对象// String path = RedisUtil.class.getClassLoader().getResource("").getPath()+"global.properties";// FileInputStream fis = new FileInputStream(path);// 属性文件输入流// p.load(fis);// 将属性文件流装载到Properties对象中// fis.close();// 关闭流// String uploadPath = p.getProperty("imgUpload.url");// //路径名称上加上-年/月日：yyyy/MMdd// uploadPath += "Uploads/"+new SimpleDateFormat("yyyy").format(new Date())+ "/" +new SimpleDateFormat("MMdd").format(new Date())+"/"; String path= request.getServletContext().getRealPath("/");path="/Users/qinshengfei/fsdownload"; logger.error("path:"+path); //路径名称上加上-年/月日：yyyy/MMdd String uploadPath = File.separatorChar+"Uploads"+File.separatorChar+new SimpleDateFormat("yyyy").format(new Date())+ File.separatorChar +new SimpleDateFormat("MMdd").format(new Date())+File.separatorChar; // 文件上传大小 long fileSize = 10 * 1024 * 1024; //判断文件大小是否超过 if (file.getSize() > fileSize) { backInfo(response, false, 2, ""); return; } //获取上传文件名称 String OriginalFilename = file.getOriginalFilename(); //获取文件后缀名：如jpg String fileSuffix = OriginalFilename.substring(OriginalFilename.lastIndexOf(".") + 1).toLowerCase(); if (!Arrays.asList(TypeMap.get("image").split(",")).contains(fileSuffix)) { backInfo(response, false, 3, ""); return; } //判断是否有文件上传// if (!ServletFileUpload.isMultipartContent(request)) {// backInfo(response, false, -1, "");// return;// } // 检查上传文件的目录 File uploadDir = new File(path+uploadPath); System.out.println(path+uploadPath); if (!uploadDir.isDirectory()) { if (!uploadDir.mkdirs()) { backInfo(response, false, 4, ""); return; } } // 是否有上传的权限 if (!uploadDir.canWrite()) { backInfo(response, false, 5, ""); return; } // 新文件名-加13为随机字符串 String newname = getRandomString(13) +"." + fileSuffix; File saveFile = new File(path+uploadPath, newname); try { file.transferTo(saveFile); backInfo(response, true, 0, uploadPath+newname); } catch (Exception e) { logger.error(e.getMessage(), e); backInfo(response, false, 1, ""); return; } } else { backInfo(response, false, -1, ""); return; } } catch (Exception e) { logger.error(e.getMessage()); } } // 返回信息 private void backInfo(HttpServletResponse response, boolean flag, int message, String fileName) { fileName=fileName.replace("\\","/"); String json = ""; if (flag) { json = "{ \"status\": \"success"; } else { json = "{ \"status\": \"error"; } json += "\",\"fileName\": \"http://127.0.0.1:8090/file/show?fileName=" + fileName + "\",\"message\": \"" + message + "\"}"; try { response.setContentType("text/html;charset=utf-8"); response.getWriter().write(json); } catch (IOException e) { logger.error(e.getMessage(), e); } }

第三步：后台处理显示图片

/** * 显示单张图片 * @return */ @RequestMapping("/show") public ResponseEntity showPhotos(String fileName){ try { String path = "/Users/qinshengfei/fsdownload"; // 由于是读取本机的文件，file是一定要加上的， path是在application配置文件中的路径 logger.error("showPhotos:"+path+fileName); return ResponseEntity.ok(resourceLoader.getResource("file:" + path + fileName)); } catch (Exception e) { return ResponseEntity.notFound().build(); } }

第四步：显示效果
