Question

Below is the test code which was working absolutely fine until now, but it is throwing below mentioned exception now.

import com.google.gson.JsonObject;
import com.google.gson.JsonParser;
import static io.restassured.RestAssured.given;
import io.restassured.response.Response;

RequestSpecification spec = new RequestSpecBuilder().setBaseUri(someBaseUri).setBasePath(someEndpoint).build();
JsonParser parser = new JsonParser();
JsonObject jsonObject = parser.parse("{\r\n\"otp\":\""+sentOtp+"\",\r\n\"otpToken\":\""+otpToken+"\"\r\n}").getAsJsonObject();
response = given().spec(spec).headers("key","value").body(jsonObject).when().post(); //the exception is thrown at this line

Below is the exception trace:

    ...

On some isolation and reviewing the commit history of my test project, I found that removing below chunk of code magically resolves the issue, while placing it back in pom.xml makes me run into the original issue again.

 <dependency>
     <groupId>io.rest-assured</groupId>
     <artifactId>json-schema-validator</artifactId>
     <version>3.0.3</version>
  </dependency>
  <dependency>
     <groupId>com.github.fge</groupId>
     <artifactId>json-schema-validator</artifactId>
     <version>2.2.6</version>
  </dependency>
  <dependency>
     <groupId>com.github.fge</groupId>
     <artifactId>json-schema-core</artifactId>
     <version>1.2.5</version>
  </dependency>

Please help.

如果你想传递Gson，你必须指定一个序列化器明确：

given().log().all().contentType(ContentType.JSON).headers("key", "value").body(jsonObject, ObjectMapperType.GSON).when().post();

实际上contentType(ContentType.JSON)会使你的输出变得美化

com.fasterxml.jackson.databind.JsonMappingException due to new maven entries
