[GitHub] [servicecomb-java-chassis] xhanthow opened a new issue #1722: 反序列化失败问题

xhanthow opened a new issue #1722:
URL: https://github.com/apache/servicecomb-java-chassis/issues/1722


   用`convertValue`报错：
   ![image](https://user-images.githubusercontent.com/7291995/79705369-03714580-82e8-11ea-8a26-b84dd724a887.png)
   报错信息如下：`Cannot construct instance of `com.huawei.educenter.oms.course.model.ForceRemovalCourseRequest` (although at least one Creator exists): no String-argument constructor/factory method to deserialize from String value ('{"courseIds":["311497735721202688"],"nextAction":1,"removalReason":"内容有问题"}')
    at [Source: UNKNOWN; line: -1, column: -1]`
   然后我用readValue是可以正常反序列化出来

   补充：
   如图，`value`类型为`String`，这样就会报错。

   但是我传`JSONObject`就ok

   用的是
   ```
           RestTemplate restTemplate = RestTemplateBuilder.create();
           String body = "{\"courseIds\":[\"311497735721202688\"],\"nextAction\":1,\"removalReason\":\"222\"}";
           // 成功
           HttpEntity entity = new HttpEntity(JSONObject.parseObject(body), httpHeaders);
           // 失败
           // HttpEntity entity = new HttpEntity(body, httpHeaders);
           ResponseEntity<Object> response = restTemplate.exchange(url, HttpMethod.POST, entity, Object.class);
   ```

   后端是一个对象， 在请求的时候， 可以使用 map或者对象实例进行请求。 不能够用 string， 因为 string的 json 字符串包含引号， 比如 : `"{"a":0}"`, 对于一个对象是 `{"a":0"}`
