i/o问题没有为类org.json.JSONObject找到序列化程序,也没有发现创建BeanSerializer的属性

Question

不知道最近发生了什么,完整的错误是:

Problem with i/o No serializer found for class org.json.JSONObject and no properties        discovered to create BeanSerializer (to avoid exception, disable SerializationConfig.Feature.FAIL_ON_EMPTY_BEANS) )

我正在尝试向RESTful服务发送PUT请求.我正在解析POST并为PUT发送'ID'和'enabled'的修改键/值对.

@Test(dependsOnMethods= {"Post"})
public void Put() throws IOException  {

logger.logTestActivity("Testing FORM data POST using Excel file");
requestBuilder = new RequestSpecBuilder();

String jsonString = "";
boolean enabledModify = false;

try {
 BufferedReader in = new BufferedReader(new FileReader(
 xmlTest.getParameter("json-post")));

String str;

while ((str = in.readLine()) != null) {
      jsonString += str;
        }

JSONObject jsonObjPut = new JSONObject(jsonString);
jsonObjPut.put("_id", createUserId);
jsonObjPut.put("enabled",enabledModify);

    System.out.println(jsonObjPut.toString());
in.close();

    requestBuilder.setContentType(ContentType.JSON);
    requestSpecification = requestBuilder.build();
    responseBuilder.expectStatusCode(Integer.parseInt(xmlTest
    .getParameter("http-status-code-200")));
    responseBuilder.expectContentType(ContentType.JSON);
    responseSpecification = responseBuilder.build();    
System.out.println(createUserId);

String responseJson = given().body(jsonObjPut).         
when().put("/" + createUserId).asString();

    System.out.println(responseJson);

logger.logTestActivity("Finished testing FORM data POST using Excel file");
} catch (AssertionError e ) {
  logger.logTestActivity(
        "Error testing FORM data post: " + e.getMessage(),logger.ERROR);

      System.out.println("REST URL: " + RestAssured.baseURI + " "
                + RestAssured.port + " " + RestAssured.basePath );
  Assert.fail("Error testing FORM data POST: " + e.getMessage());
        throw e;
} catch (IOException | JSONException e) {
   System.out.println("Problem with i/o" + e.getMessage()); 
    }
}

createUserID是一个全局变量,它是从POST解析的ID.

正在解析的JSON文件如下所示:

{
"enabled" : false,
"_id" : "fdse332a-22432d-4432b"
}

在之前的测试方法中,我正在使用所有适当的url端点设置restassured ...

此外,PUT也失败,出现NULLPointerException错误.这可能是未来的另一篇文章!

Answer 1

解决方案:在传递给restassured时,我没有将我的JSON对象转换为字符串.

String responseJson = given().body(jsonObjPut.toString).

这样做了.我现在使用生成的ID修改现有的json,并在RESTful服务上成功执行PUT.
