JSON字符串，转为对象操作失败not match : - =, info : pos 10, line 1, column 11

• 报错信息

  not match : - =, info : pos 10, line 1, column 11
  

• 错误的代码

  //使用JSONObject接受前端的回传
  //@RequestBody JSONObject jsonParam
  @PostMapping("/inserts")
  	public R inserts(@RequestBody JSONObject jsonParam){
  		String data = jsonParam.getString("data");
  		//List<Drugregistration> drugregistrationList =  (List<Drugregistration>) JSONArray.parseArray(data, Drugregistration.class);
  		List<Drugregistration> drugregistrationList =JsonUtils.fromListJson(data,Drugregistration.class );
  		boolean isok = drugregistrationService.saveBatch(drugregistrationList);
  		return R.ok(isok);
  	}
  
  

• 正确的代码

  //改成String接收前端回传,然后再将字符串通过JSONObject.parseObject(str)转换成Json对象
  //@RequestBody String str
  @PostMapping("/inserts")
  	public R inserts(@RequestBody String str){
  		JSONObject jsonObject = JSONObject.parseObject(str);
  		String data = jsonObject.getString("data");
  		//List<Drugregistration> drugregistrationList =  (List<Drugregistration>) JSONArray.parseArray(data, Drugregistration.class);
  		List<Drugregistration> drugregistrationList =JsonUtils.fromListJson(data,Drugregistration.class );
  		boolean isok = drugregistrationService.saveBatch(drugregistrationList);
  		return R.ok(isok);
  	}
  
  

主要的问题就出现在getString这句代码

错误代码中getString得到的值为
{id=66, firmware_id=15, version=V20190617_170943, file_hash=c9782aeff870c229f4a9d3efbaa11fa7, file_size=511020, description=测试, product_id=8}
而正确代码中得到的是
{"id":"66","firmware_id":"15","version":"V20190617_170943","file_hash":"c9782aeff870c229f4a9d3efbaa11fa7","file_size":"511020","description":"测试","product_id":"8"}
错误的代码中得到的值，没有双引号，是一个对象型的，parseObject转换需要是一个字符串因而报错
