Service层:

/** 
     * 读取excel中的数据,生成list 
     */  
String readExcelFile(byte[] pic, String name);

ServiceImpl实现层:

public String readExcelFile(byte[] pic,String name) {

			String result ="";
				//创建处理EXCEL的类  
			ReadExcel readExcel=new ReadExcel();
			//解析excel,获取上传的事件单
			List area = readExcel.getExcelInfo(pic,name);
			for (int i = 0; i < area.size(); i++) {
				System.out.println("areaLevel="+area.get(i).getLevel());
				areabean.insertArea(area.get(i));
			}
			
			if(area != null && !area.isEmpty()){
				result = "上传成功";
			}else{
				result = "上传失败";
			}
			return result;
		}

Controller控制层:

public String bulkImport(@RequestParam(value="file",required = false)MultipartFile file,HttpServletRequest request, HttpServletResponse response) throws IOException{
		byte[] pic = file.getBytes();
		String name = file.getOriginalFilename();
		String result = dmsAreaService.readExcelFile(pic,name);
		return result;
	}

到这一步如果报NULL错在properties加配置文件:
#关闭springboot自带上传组件
spring.http.multipart.enabled=false。

到这一步如果报:Dubbo-Fail to decode request due to: RpcInvocation

将MultipartFile流用byte去进行传输,问题原因,dubbo不支持将MultipartFile序列化。我上面代码已经将MultipartFile用byte代为传输了。
另外我的框架是springboot+mybatis+dubbo,如果框架不同可能会有些许的不同。
比如不用springboot和用springboot以及用springboot+dubbo三者之间就会有些许的不同
