SpringBoot+GraphQL集成测试报错：Body is empty with status 401

执行JUnit测试用例时出现如下栈追踪错误：

java.lang.NullPointerException: Body is empty with status 401

at java.base/java.util.Objects.requireNonNull(Objects.java:347)
at com.graphql.spring.boot.test.GraphQLResponse.<init>(GraphQLResponse.java:24)
at com.graphql.spring.boot.test.GraphQLTestTemplate.postRequest(GraphQLTestTemplate.java:142)
at com.graphql.spring.boot.test.GraphQLTestTemplate.post(GraphQLTestTemplate.java:137)
at com.graphql.spring.boot.test.GraphQLTestTemplate.perform(GraphQLTestTemplate.java:95)
at com.graphql.spring.boot.test.GraphQLTestTemplate.postForResource(GraphQLTestTemplate.java:116)

以下是相关配置内容：

pom.xml依赖 #

<dependency>
        <groupId>com.graphql-java-kickstart</groupId>
        <artifactId>graphql-spring-boot-starter</artifactId>
        <version>7.0.1</version>
    </dependency>
    <dependency>
        <groupId>com.graphql-java-kickstart</groupId>

集成测试代码 #

@RunWith(SpringRunner.class)
@SpringBootTest(webEnvironment = SpringBootTest.WebEnvironment.RANDOM_PORT, classes = GraphQLEntryApplication.class)

public class PhysicianStorageContractIntegrationTest {

@Autowired
private GraphQLTestTemplate graphQLTestTemplate;

@Test
public void shouldGetAllPhysiciansByLocationId() throws IOException, JSONException {
    var operationName = "GetAllPhysiciansByLocationId";
    GraphQLResponse graphqlResponse = graphQLTestTemplate.postForResource(String.format(ContractIntegrationTestUtils.GRAPHQL_QUERY_REQUEST_PATH, operationName));
    var expectedResponseBody = ContractIntegrationTestUtils.readResponse(String.format(ContractIntegrationTestUtils.GRAPHQL_QUERY_RESPONSE_PATH, operationName));

    Assertions.assertThat(graphqlResponse.getStatusCode()).isEqualTo(HttpStatus.OK);
    JSONAssert.assertEquals(expectedResponseBody, graphqlResponse.getRawResponse().getBody(), true);
}
}

集成测试工具类 #

public final class ContractIntegrationTestUtils {

public static final String CONTENT_TYPE_KEY = "Content-Type";
public static final String MEDIATYPE_APP_JSON = "application/json";

public static final String GRAPHQL_QUERY_REQUEST_PATH = "contract-integration-physician-storage/request/%s.graphql";
public static final String GRAPHQL_QUERY_RESPONSE_PATH = "contract-integration-physician-storage/response/%s.json";

public static String readResponse(String responsePath) throws IOException {
    return IOUtils.toString(new ClassPathResource(responsePath).getInputStream(), UTF_8);
}
}

GraphQL请求文件 #

query allPhysiciansByFacilityIdWithNoPagination {
allPhysiciansByFacilityIdWithNoPagination(locationId: 13613){
    totalSize
    physicians {
        firstName
        lastName
        middleInitials
    }
}
}

响应文件 #

{
  "data": {
    "allPhysiciansByFacilityIdWithNoPagination": {
      "totalSize": 4,
      "physicians": [
        {
          "firstName": "John",
          "lastName": "Doe",
          "middleInitials": null
        },
        {
          "firstName": "Chandler",
          "lastName": "Bing",
          "middleInitials": "K"
        },
        {
          "firstName": "Katy",
          "lastName": "Perry",
          "middleInitials": null
        },
        {
          "firstName": "Ross",
          "lastName": "Geller",
          "middleInitials": null
        }
      ]
    }
  }
}

推测该问题和安全配置有关，知道用MockMvc可以禁用安全配置，但不确定使用SpringBoot的GraphQL Test库是否可行，求解决思路或线索。
