我直接下载的demo，用servlet改写了jsp，没有问题，但是现在用springboot，就出现了这种问题。
不废话，直接上代码，恳请各位大神的指导：
html：

    <link rel="stylesheet" href="/kindeditor-master/themes/default/default.css" />
    <link rel="stylesheet" href="/kindeditor-master/plugins/code/prettify.css" />
    <script charset="utf-8" src="/kindeditor-master/kindeditor-all.js"></script>
    <script charset="utf-8" src="/kindeditor-master/lang/zh-CN.js"></script>
    <script charset="utf-8" src="/kindeditor-master/plugins/code/prettify.js"></script>
    <script>

        KindEditor.ready(function(K) {
            K.create('textarea[name="content1"]', {
                cssPath : '/kindeditor-master/plugins/code/prettify.css',
                uploadJson : '/kindEditor/upLoad',
                fileManagerJson : '/kindEditor/Manager',
                allowFileManager : true,//是否允许浏览服务器上传文件
                //resizeType : 0,是否可改变编辑器大小0不可以，1可改高度，2都可以。默认为2
                afterCreate : function(msg) {
                    var self = this;
                    K.ctrl(document, 13, function() {
                        self.sync();
                        document.forms['example'].submit();
                    });
                    K.ctrl(self.edit.doc, 13, function() {
                        self.sync();
                        document.forms['example'].submit();
                    });
                }
            });
            prettyPrint();
        });
    </script>

这是文件上传类：

    }
}

正常的效果应该是上传完图片后在富文本框内也是正常显示图片。现在可以上传，但是富文本框内的图片无法正常显示。在文件管理里面，可以找到相应的文件夹或者图片，但是图片也无法正常显示。

结果如下：
