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 [英] Issue with i/o No serializer found for class org.json.JSONObject and no properties discovered to create BeanSerializer

问题描述

不确定发生了什么，完整的错误是:

not sure whats going on, the full error is:

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) )

我正在尝试将PUT请求发送到RESTful服务.我正在解析POST，并为PUT发送修改后的"ID"和"enabled"键/值对.

I am trying to send a PUT request to a RESTful service. I am parsing a POST And sending modified key/value pairs for 'ID' and 'enabled' for the PUT.

@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.

createUserID is a global variable that is the ID parsed from the POST.

正在解析的JSON文件如下所示:

JSON file that is getting parsed looks like this:

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

在之前的测试方法中，我使用所有适当的url端点设置了放心的东西...

In a before test method I am setting up the restassured with all the appropriate url endpoints...

此外，PUT也失败，并出现NULLPointerException错误.那可能是将来的另一篇文章！

Also, the PUT is also failing, with a NULLPointerException Error. That may be another post in the future!

推荐答案

解决方案:传递给我保证时，我没有将JSON对象转换为字符串.

Solution: I was not converting my JSON object to a string when passing to restassured.

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

这成功了.现在，我用生成的ID修改现有的json，并在RESTful服务上成功执行PUT.

This did the trick. I now modify my existing json with generated ID and do a successful PUT on the RESTful service.
