        @change="onEditorChange($event)"
      >
      </quill-editor>
    </div>

4.js

<script>
  const toolbarOptions = [
    ['bold', 'italic', 'underline', 'strike'],        // toggled buttons
    [{'header': 1}, {'header': 2}],               // custom button values
    [{'list': 'ordered'}, {'list': 'bullet'}],
    [{'indent': '-1'}, {'indent': '+1'}],          // outdent/indent
    [{'direction': 'rtl'}],                         // text direction
    [{'size': ['small', false, 'large', 'huge']}],  // custom dropdown
    [{'header': [1, 2, 3, 4, 5, 6, false]}],
    [{'color': []}, {'background': []}],          // dropdown with defaults from theme
    [{'font': []}],
    [{'align': []}],
    ['link', 'image'],
    ['clean']

  ]
  export default {
    data() {
      return {
        quillUpdateImg: false, // 根据图片上传状态来确定是否显示loading动画，刚开始是false,不显示
        content: null,
        editorOption: {
          placeholder: '',
          theme: 'snow',  // or 'bubble'
          modules: {
            toolbar: {
              container: toolbarOptions,
              handlers: {
                'image': function (value) {
                  if (value) {
                    // 触发input框选择图片文件
                    document.querySelector('.avatar-uploader input').click()
                  } else {
                    this.quill.format('image', false);
                  }
                }
              }
            }
          }
        },
        serverUrl: '/manager/common/imgUpload',  // 这里写你要上传的图片服务器地址
        header: {
          // token: sessionStorage.token
        } // 有的图片服务器要求请求头需要有token
      }
    },
    methods: {
      onEditorChange({editor, html, text}) {//内容改变事件
        console.log("---内容改变事件---")
        this.content = html
        console.log(html)
      },
      // 富文本图片上传前
      beforeUpload() {
        // 显示loading动画
        this.quillUpdateImg = true
      },

      uploadSuccess(res, file) {
        // res为图片服务器返回的数据
        // 获取富文本组件实例
        console.log(res);
        let quill = this.$refs.myQuillEditor.quill
        // 如果上传成功
        if (res.code == 200 ) {
          // 获取光标所在位置
          let length = quill.getSelection().index;
          // 插入图片  res.url为服务器返回的图片地址
          quill.insertEmbed(length, 'image', res.url)
          // 调整光标到最后
          quill.setSelection(length + 1)
        } else {
          this.$message.error('图片插入失败')
        }
        // loading动画消失
        this.quillUpdateImg = false
      },
      // 富文本图片上传失败
      uploadError() {
        // loading动画消失
        this.quillUpdateImg = false
        this.$message.error('图片插入失败')
      }
    }
  }

注意：serverUrl :文件上传地址不能直接写全路径，会出现跨域问题报错。需要在conf/index.js 中进行配置

module.exports = {
  dev: {
    // Paths
    assetsSubDirectory: 'static',
    assetsPublicPath: '/',
    host: 'localhost', // can be overwritten by process.env.HOST
    port: 8088, // can be overwritten by process.env.PORT, if port is in use, a free one will be determined
    autoOpenBrowser: true,
    cssSourceMap: true,
    proxyTable: {
      '/api': {
        target: 'http://localhost:18080/', //设置调用接口域名和端口号别忘了加http
        changeOrigin: true,
        pathRewrite: {
          '^/api': '/' //这里理解成用‘/api’代替target里面的地址，组件中我们调接口时直接用/api代替
          // 比如我要调用'http://0.0:300/user/add'，直接写‘/api/user/add’即可 代理后地址栏显示/
        }
      },
      '/manager': {
        target: 'http://localhost:18081/',
        changeOrigin: true,
        pathRewrite: {
          '^/manager': '/'
        }
      }
    }

  },

5.style

<style>
  .ql-editor.ql-blank, .ql-editor {
    height: 350px;
  }
</style>

6.后台图片上传接口

 @RequestMapping(value = "/imgUpload")
    public Map<String ,Object> imgUpload(HttpServletRequest req, MultipartHttpServletRequest multiReq)
            throws IOException {
       
        FileOutputStream fos = new FileOutputStream(
                new File("E://fileupload//upload.jpg"));
        FileInputStream fs = (FileInputStream) multiReq.getFile("img").getInputStream();
        byte[] buffer = new byte[1024];
        int len = 0;
        while ((len = fs.read(buffer)) != -1) {
            fos.write(buffer, 0, len);
        }
        fos.close();
        Map<String ,Object> map=new HashMap<>();
        map.put("code",200);
        map.put("msg","上传成功");
        map.put("url","http://localhost:8080/tomcat.png");
        return map;//这里只做返回值测试用，url 参数为图片上传后访问地址。具体根据功能进行修改}

7.效果如下
