Springboot 使用wangEditor3.0上传图片

wangEditor是一个很好用的富文本编辑器,可以上传图片到服务器上,存放位置为Tomcat目录下

Springboot启动时自带Tomcat,重新启动时以前上传的图片便会丢失

研究了一下,给出一种可行性方法,思路就是每次上传图片至Tomcat时复制同名图片到指定文件夹中,下次启动时从指定文件夹复制图片到Tomcat中

如果大家有更好的方法不吝赐教

开发工具STS,Springboot2.0

JS代码

<div id="div1" style="left:15%;width:70%;position:absolute;">
    <p>欢迎使用 wangEditor 编辑器</p>
</div>
<button id="btn1">获取html</button>
<button id="btn2">获取text</button>
<script type="text/javascript" src="/wangEditor.min.js"></script>
<script type="text/javascript">
    var E = window.wangEditor
    var editor = new E('#div1')
    editor.customConfig.debug=true;
    editor.customConfig.uploadImgServer = '/upload'
    editor.customConfig.uploadFileName = 'myFileName';
    editor.customConfig.debug = true
    editor.create()
    
	    document.getElementById('btn1').addEventListener('click', function () {
        // 读取 html
    }, false)
    document.getElementById('btn2').addEventListener('click', function () {
        // 读取 text
        alert(editor.txt.text())
    }, false)
</script>

　　Controller

   @RequestMapping("/upload")
	public Map upload(HttpServletRequest request,@RequestParam(value="myFileName")MultipartFile file) throws IllegalStateException, IOException {
		String pathRoot = request.getSession().getServletContext().getRealPath("upload"); 
		String fileName = file.getOriginalFilename();//获取图片名称
		String path = pathRoot+"\\"+fileName;
		System.out.println(path);
		  File dest = new File(path);
  	    // 检测是否存在目录
  	    if (!dest.getParentFile().exists()) {
  	        dest.getParentFile().mkdirs();// 新建文件夹
  	    }
  	    file.transferTo(dest);// 文件写入
  	    
		String path2="D:\\aim\\upload"+"\\"+fileName;
		UtilTools.copyFile(path, path2);
    	Map map=new HashMap();
    	map.put("errno", 0);
    	path="http://localhost:8069/upload/"+fileName+"";
    	List list=new ArrayList();
    	list.add(path);
    	map.put("data", list);
    
    	
    	
    	return map;
