yaml转json，需要的pom依赖

		    <groupId>org.yaml</groupId>
		    <artifactId>snakeyaml</artifactId>

    	JSONObject obj = JSONObject.parseObject("{}");
    	
    	try {
    		
			InputStream inputstream = mfile.getInputStream();
			String str = IOUtils.toString(inputstream);
			//yaml转json
	        Yaml yaml = new Yaml();
			String jsonstr = JSONObject.toJSONString(yaml.load(str));
			JSONObject json = JSONObject.parseObject(jsonstr);
			
			obj.put("code", 200);
			obj.put("msg", "success");
	    	obj.put("data", json);
			
		} catch (IOException e) {
			obj.put("code", 400);
