百度ueditor富文本编辑器实现上传文件、图片、视频到ftp服务器并在页面端回显

之前一直用ueditor作为富文本编辑器，想要实现图片上传到ftp的功能，网上搜索了一圈，发现都感觉讲的不是很明白，而且有不少要引入其他的java代码，最近自己试了一下，终于调通了，希望能帮到各位。废话不多说，查看步骤。（注意，这个是springboot版本，其实springmvc的也差不多，有一点点不同，最后我会说明）

1.将utf8-jsp的整个文件夹复制到resources的static目录下，打开之后目录如下。

项目目录如下（我多加了一层ueditor目录，不过也一样）

2.写两个controller，代码如下（请忽略楼主潦草的代码，自己拿回去调整一下，修改一下UploadController中ftp的地址，密码即可，总共有三个地方）

1.UploadController

}

　3.修改ueditor.config.js

var URL = window.UEDITOR_HOME_URL || getUEBasePath();
    var server_url = window.location.protocol+"//"+window.location.hostname+":"+window.location.port;

    /**
     * 配置项主体。注意，此处所有涉及到路径的配置别遗漏URL变量。
     */
    window.UEDITOR_CONFIG = {

        //为编辑器实例添加一个路径，这个不能被注释
        UEDITOR_HOME_URL: URL

        // 服务器统一请求接口路径
        // , serverUrl: URL + "jsp/controller.jsp"
        , serverUrl: server_url+"/configNew"

　4.修改ueditor的jsp目录下的config.json文件目录图片如下

　　　打开这个文件之后修改大概7.8个地方的参数，都是xxxUrlPrefix，反正只要是图片注释就换成Ueditortxtcontroller中的getIMg路径，文件就换成downloadFile路径

　　图片

　　文件路径

　　5.关键一步，记得在你的启动类application中排除掉有关文件上传的自动配置。

如果是springmvc，那就是在xml文件中注释掉multipartfile这个bean了

6.然后是改造的你的编辑器的访问页面index.html。

在ue.ready方法中换掉相关原有的访问路径即可

这是楼主的html页面，如果要用的话，记得把那个juqery-3.5.1.min.js和一个保存saveContent的方法排除掉就可以了
