KindEditor 编辑器在springboot使用

官网下载kindEditor

 1. 官网地址 ： http://kindeditor.net/down.php 

2.下载后解压；将解压文件引入到项目中

由于在java中使用；去掉不用的文件 asp,asp.net jsp；

3.引入js,我这里使用的是thymeleaf模板
4.html页面引入 ；也可以在页面直接引入js ; 添加文本框

 
   添加页面：  编辑页面：  

5. 初始化富文本框

 ```var editor; KindEditor.ready(function (K) { 
    editor = K.create('textarea[name="context"]', { 
    allowImageUpload:true, allowImageRemote: false, //是否允许浏览服务器已上传文件,默认是false allowFileManager: true, uploadJson :"/kindEditor/uploadFile", fileManagerJson: "/kindEditor/fileManagerJson", afterBlur: function(){ 
   this.sync();}, afterUpload : function(url, data, name) { 
    //上传文件后执行的回调函数，必须为3个参数 if (name == "image" || name == "multiimage") { 
    //单个和批量上传图片时 var img = new Image(); img.src = url; img.onload = function () { 
    //图片必须加载完成才能获取尺寸 } } } }); }); 

后台代码：

 @Controller @RequestMapping("/kindEditor") @Slf4j public class KinUploadController extends BaseController { 
    @Autowired private UploadFilePathConfig filePathConfig; @Autowired private ServerConfig serverConfig; / * 提供KindEditor作文件上传使用 * @param request * @param response * @throws Exception */ @PostMapping("/uploadFile") public void uploadFile(HttpServletRequest request, HttpServletResponse response) throws Exception {

解决视频上传问题

由于kinEditor中视频标签是,h5页面可能不支持，我们需要修改kindeditor-all.js文件

1-1. 打开kindeditor-all.js 在304行的地方添加 Video标签

 video: ['id', 'class', 'src', 'width', 'height', 'type', 'loop', 'autoplay', 'quality', '.width', '.height', 'align', 'controls', 'muted','controlslist'], 

1-2. 然后找到 _mediaEmbed(attrs)方法；大概在 955 行

function _mediaEmbed(attrs) { 
    var html = '; _each(attrs, function(key, val) { 
      html += key + '="' + val + '" '; }); html += '/>'; return html; } 替换为： function _mediaEmbed(attrs) { 
      var html = '; _each(attrs, function(key, val) { 
        html += key + '="' + val + '" '; }); html += '/>'; // 一段简单的代码 解决视频上传问题 if (attrs.type=="video/mp4"){ 
        var html = ' 
       

1-3 找到 _mediaType(src)函数； 大概在929左右

在这个方法中添加 if (/\.(mp4)(\?|$)/i.test(src)) { 
    return 'video/mp4'; } if (/\.(ogg)(\?|$)/i.test(src)) { 
    return 'video/ogg'; } if (/\.(webm)(\?|$)/i.test(src)) { 
    return 'video/webm'; } 添加后： function _mediaType(src) { 
    if (/\.(rm|rmvb)(\?|$)/i.test(src)) { 
    return 'audio/x-pn-realaudio-plugin'; } if (/\.(swf|flv)(\?|$)/i.test(src)) { 
    return 'application/x-shockwave-flash'; } if (/\.(mp4)(\?|$)/i.test(src)) { 
    return 'video/mp4'; } if (/\.(ogg)(\?|$)/i.test(src)) { 
    return 'video/ogg'; } if (/\.(webm)(\?|$)/i.test(src)) { 
    return 'video/webm'; } return 'video/x-ms-asf-plugin'; }
