个人用过很多富文本编辑器，还是 tinymce 好用。

本文介绍一下 tinymce 编辑器的简单使用。

一、下载 tinymce

tinymce 下载地址：http://download.tiny.cloud/tinymce/community/tinymce_5.6.2.zip

中文汉化包：http://tinymce.ax-z.cn/static/tiny/langs/zh_CN.js

将 zh_CN.js 拷贝到 lang 中

如图

二、完整代码

1、引入JS文件

<script src="/static/tinymce/tinymce.min.js"></script>

2、创建 textarea 元素

 <textarea id="postContent"></textarea>

3、实例化 tinymce 编辑器

<script>
    tinymce.init({
        selector: '#postContent',
        language: "zh_CN",
        height: 600,
        theme: "silver",
        browser_spellcheck: true, // 拼写检查
        branding: true, // 去水印
        // elementpath: false,  //禁用编辑器底部的状态栏
        statusbar: false, // 隐藏编辑器底部的状态栏
        paste_data_images: true, // 允许粘贴图像
        menubar: true, // 隐藏最上方menu
        fontsize_formats:
            "12px 13px 14px 15px 16px 17px 18px 20px 22px 24px 26px 30px 35px 40px 50px",
        plugins:
            "print preview fullpage searchreplace autolink directionality visualblocks visualchars fullscreen image link media template codesample table charmap hr pagebreak nonbreaking anchor toc insertdatetime advlist lists textcolor wordcount  imagetools  contextmenu colorpicker textpattern help code",
        toolbar:
            "formatselect | bold italic strikethrough forecolor backcolor fontsizeselect | link image  | alignleft aligncenter alignright alignjustify  | numlist bullist outdent indent  | removeformat| code",
        paste_webkit_styles: true,
        paste_data_images: true,  //  设置为允许粘帖图片
        images_upload_url: '/admin/file/upload', //  图片上传地址
        contextmenu: `inserttable | cell row column deletetable`,
        relative_urls: false,
        remove_script_host: false
    });

</script>

4、后台上传接口代码

核心是返回JSON格式，文件路径字段必须为 location 

/**
 * 上传文件
 *
 * @param file file
 * @return Map
 */
@PostMapping(value = "/admin/file/upload", produces = {"application/json;charset=UTF-8"})
@ResponseBody
public Map<String, Object> uploadFile(@RequestParam("file") MultipartFile file) {
    Map<String, Object> map = new HashMap<>(1);
    String path = FileUtil.upload(file);
    map.put("location", path);
    return map;
}

三、效果图

可以在 http://chuyunblog.liuyanzhao.com/admin/post/new 体验，账号密码 admin/123456

四、代码高亮

引入 两个文件

<link rel="stylesheet" href="static/css/prettify.css">
<script src="/static/js/prettify.js"></script>

这两个文件代码如下
