thymeleaf + ueditor实现图片上传和回显

1,下载ueditor放到项目中,导入相关jar包,commons-io框架有就没导入


	    com.gitee.qdbp.thirdparty
	    ueditor
	    1.4.3.3
	
	
	    org.json
	    json
	    20180813
	
    
        commons-codec
        commons-codec
        1.9
    
	
		commons-fileupload
		commons-fileupload
		1.3.2
	

2,ueditor/jsp下有两个重要文件controller.jsp和config.json,controller.jsp作用是把config.json返回给ueditor,因为我们用的是thymeleaf所有是没法用的。所有我们要自己写一个UeditorController类来代替controller.jsp。
2.1:修改ueditor/ueditor.config.js

, serverUrl: "ueditor/configJson"

2.2:把config.json放到resources目录下
2.3:自定义UeditorController类,返回config.json

@RequestMapping(value="/ueditor/configJson")  
	@ResponseBody
    public String config(HttpServletRequest request, HttpServletResponse response){  
        response.setContentType("application/json");
        StringBuilder sb = new StringBuilder();
        String line;
        //获取config.json路径
        Resource resource = new ClassPathResource("config.json");
        
        try(BufferedReader bf = new BufferedReader(new FileReader(resource.getFile()));) {
			while((line=bf.readLine()) != null) {
				sb.append(line);
			}
		} catch (IOException e) {
			e.printStackTrace();
			return "error";
		}
        return sb.toString();
    } 

3,自定义请求地址,可以参考官方文档的5.3

uploadimage://执行上传图片或截图的action名称
uploadscrawl://执行上传涂鸦的action名称
uploadvideo://执行上传视频的action名称
uploadfile://controller里,执行上传视频的action名称
catchimage://执行抓取远程图片的action名称
listimage://执行列出图片的action名称
listfile://执行列出文件的action名称

3.1:在实例化ueditor编辑器的页面添加如下代码

var base_dir = "[[@{/}]]";
UE.getEditor('editor')就能拿到相关的实例
    var ue = UE.getEditor('editor');
    UE.Editor.prototype._bkGetActionUrl = UE.Editor.prototype.getActionUrl;
    UE.Editor.prototype.getActionUrl = function(action) {
        if (action == 'uploadimage') {
            return base_dir+'ueditor/uploadImage';//这里写自己的路径如: localhost:8080:/myapp/ueditor/uploadImage
        } else {
            return this._bkGetActionUrl.call(this, action);
        }
    }

3.2:实现图片上传,可以参考官方文档3.3

//请求参数
GET {"action": "uploadimage"}
POST "upfile": File Data
//返回值
{
    "state": "SUCCESS",
    "url": "upload/demo.jpg",
    "title": "demo.jpg",
    "original": "demo.jpg"
}

有了请求参数和返回值我们可以自己实现
UeditorController类下

@RequestMapping("/ueditor/uploadImage")
	@ResponseBody
	public UeditorUploadResult uploadImage(MultipartFile upfile) {
		//获取上传图片的原名
		String oldName = upfile.getOriginalFilename();
		//避免重复重新取名
		String newName = new Date().getTime() + oldName;
		String path = "E:\\udUpdate\\" + newName;
		System.out.println(path);
		try {
			upfile.transferTo(new File(path));//保存到硬盘
		} catch (IllegalStateException | IOException e) {
			// 我偷懒返回null了
			e.printStackTrace();
			return null;
		}
		//设置返回值
		UeditorUploadResult result = new UeditorUploadResult();//这个是自定义返回参数类
		//图片保存到硬盘path,访问路径是url
		result.setUrl("/pic/" + newName);//这里是图片服务器的地址url,相当于localhost:8080/boboblog/pic + newName
		result.setTitle(newName);
		result.setOriginal(oldName);
		result.setState("SUCCESS");
		return  result;
	}

直接保存到硬盘没法回显,所以我直接用的是一个简单图片服务器,
