springboot 整合文本编辑器（图片上传）

Ueditor

文件上传配置：
ueditor.config.js
serverUrl：填写自己的路径

jsp->config.json：
imageActionName：填写自己写的文件上传的路径

页面：
1.引入：ueditor.config.js ueditor.all.js lang/zh-cn/zh-cn.js
2.创建实例：

<form action="/ueditor/uploadContent.action" method="post">
    <script type="text/plain" id="uploadEditor" name="myContent">
    </script>
    <input type="submit" name="submit" value="提交">
</form>

//实例化编辑器
    var ue = UE.getEditor('uploadEditor',{
        enableAutoSave:false,
        autoHeightEnabled: true,
        autoFloatEnabled: true,
        scaleEnabled:true,//滚动条
        initialFrameHeight:400 //默认的编辑区域高度
    });

    UE.Editor.prototype._bkGetActionUrl = UE.Editor.prototype.getActionUrl;
    UE.Editor.prototype.getActionUrl = function(action) {
        if (action == 'uploadimage' || action == 'uploadscrawl' || action == 'uploadimage') {
            return 'http://localhost/ueditor/imgUpdate'; //在这里返回我们实际的上传图片地址
        } else {
            return this._bkGetActionUrl.call(this, action);
        }
    }

Controller：

@Controller
@RequestMapping("/ueditor")
public class FileController {
    @RequestMapping(value = "/file")
    @ResponseBody
    public String file(HttpServletRequest request) {
        String s = "{\n" +

        return s;
    }

    public String imgUpdate(MultipartFile file,HttpServletRequest request) throws FileNotFoundException {
        if (file.isEmpty()) {

        }
        // 获取文件名
        String fileName = file.getOriginalFilename();

        System.out.println(content);

wangEditor

1.引入js
release/wangEditor.js
2.创建实例和路径配置

<div id="editor">
    <p>欢迎使用 <b>wangEditor</b> 富文本编辑器</p>
</div>

<script type="text/javascript">
    var E = window.wangEditor;
    var editor = new E('#editor');
    editor.customConfig.uploadImgServer = '/upload'; //上传URL
    editor.customConfig.uploadImgMaxSize = 3 * 1024 * 1024;
    editor.customConfig.uploadImgMaxLength = 5;
    editor.customConfig.uploadFileName = 'myFileName';
    editor.customConfig.uploadImgHooks = {
        customInsert: function (insertImg, result, editor) {
            // 图片上传并返回结果，自定义插入图片的事件（而不是编辑器自动插入图片！！！）
            // insertImg 是插入图片的函数，editor 是编辑器对象，result 是服务器端返回的结果

            // 举例：假如上传图片成功后，服务器端返回的是 {url:'....'} 这种格式，即可这样插入图片：
            var url =result.data;
            insertImg(url);

            // result 必须是一个 JSON 格式字符串！！！否则报错
        }
    }
    editor.create();
