之前写vue项目时用过vue-quill-editor，但是这个编辑器太简单了，无法添加自己想要的样式，所以就重新封装了一个tinymce，可以粘贴源码，非常强大。步骤如下：

首先在index.html中引入 <script src="https://cdn.bootcss.com/tinymce/4.7.13/tinymce.min.js"></script>，这样就可以不用安装依赖了。

<template>
  <div>
    <textarea :id='id' v-model='value'></textarea>
  </div>
</template>

<script>
  export default {
    props: {
      value: String,
      path: String, // 上传图片的路径
      height: String // 编辑器的高度，使用组件时自己传，不穿下面设置了默认300
    },
    watch: {
      value(val) {
        if (window.tinymce.activeEditor) {
          if (this.status === 0 || window.tinymce.activeEditor.getContent() !== val) {
            if (val == null) {
              val = ''
            }
            window.tinymce.activeEditor.setContent(val)
          }
          this.status = 2
        }
      }
    },
    data() {
      return {
        status: 0,
        id: '',
        setting: { // 配置富文本编辑器高
          height: this.height || 300
        },
        Url: ('/api/upload/file?path=' + this.path) || '/api/upload/file?path=img/tinymce',
        maxSize: 11100000, // 文件大小
        accept: 'image/jpeg, image/png, image/jpg', // 文件格式
        withCredentials: true
      }
    },
    mounted() {
      this.init()
    },
    methods: {
      init() {
        const radomId = window.radomId ? window.radomId + 1 : 1
        window.radomId = radomId
        const _this = this
        _this.status = 0
        _this.id = 'editor-' + radomId
        const setting =
          {
            selector: '#' + _this.id,
            upload_image_url: '/upload/cloud', // 配置的上传图片的路由
            language_url: '/static/langs/zh_CN.js',
            language: 'zh_CN',
            init_instance_callback: function(editor) {
              editor.on('input change undo redo', () => {
                _this.$emit('input', editor.getContent())
              })
            },
// 编辑器的一些简单样式设置
            content_style: `

    },
    beforeDestroy: function() {
      window.tinymce.get(this.id).destroy()
    }
  }
</script>
<style scoped lang="less" rel="stylesheet/less">
  .tinymce {
    padding: 0;
  }
</style>

以上设置后，就可以在其他组件中引入使用了。
