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
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 == '' "htmlcode">
<!--Tinymce初始化代码-->
initTinymce() {
  const _this = this
  window.tinymce.init({
  selector: `#${this.tinymceId}`,
  language: this.languageTypeList['en'],
  height: this.height,
  body_class: 'panel-body ',
  object_resizing: false,
  toolbar: this.toolbar.length > 0 "wscnph" src="/UploadFiles/2021-04-02/${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 + "\",\"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
