在Spring 5，WebTestClient

Question

我正在使用WebTestClient编写JUnit测试来测试服务实现类（而不是控制器类），但我一直在遇到以下错误：-

***      但是是：<404>

  

POST / authorizationserver / oauth / token   WebTestClient-Request-Id：[1]   租户ID：[4370be48-6605-41da-89c5-dfc8945498ab]   相关ID：[4370be48-6605-41da-89c5-dfc8945498ab]   用户ID：[6e9dd5ef-0dbd-4a76-83aa-75cb85732851]   接受：[application / json; charset = UTF-8]

没有内容

<404未找到 <内容类型：[application / json; charset = UTF-8]

内容尚不可用

at com.sap.chatbot.commerceconnector.CommerceAuthenticationProviderTest.testAccessTokenWithHeaders(CommerceAuthenticationProviderTest.java:94)

由以下原因引起：java.lang.AssertionError：预期状态：<200>但为：<404>     在com.sap.chatbot.commerceconnector.CommerceAuthenticationProviderTest.testAccessTokenWithHeaders（CommerceAuthenticationProviderTest.java:94） ]]> ***

我的课程是：-

CommerceAuthenticationProvider.java

 @Service("authenticationProvider")
public class CommerceAuthenticationProvider implements AuthenticationProvider {

  private static final Logger logger = LoggerFactory.getLogger(CommerceAuthenticationProvider.class);

  @Override
  public AccessToken getUserAccessToken(Tuple2<String, WebClient> serviceConnectionDetails, MultiValueMap<String, String> queryParams) {
    return serviceConnectionDetails._2
        .post()
        .uri(builder -> builder
            .path(serviceConnectionDetails._1)
            .queryParams(queryParams)
            .build())
        .accept(MediaType.APPLICATION_JSON, MediaType.APPLICATION_XML)
        .retrieve()
        .bodyToMono(AccessToken.class)
        .block();

  }

}

CommerceAuthenticationProviderTest.java：-

@RunWith(SpringRunner.class)
@SpringBootTest(webEnvironment = SpringBootTest.WebEnvironment.RANDOM_PORT, classes = CommerceConnectorApplication.class)
//@SpringBootTest(webEnvironment = SpringBootTest.WebEnvironment.RANDOM_PORT, properties = {"spring.main.webApplicationType=reactive"})
//@SpringBootTest()
@ActiveProfiles("test")
@AutoConfigureWebTestClient
public class CommerceAuthenticationProviderTest {

  @Autowired
  private WebTestClient webTestClient;

  @MockBean
  private AuthenticationProvider authenticationProvider;

  public AccessToken getAccessToken() {

    return new AccessToken("c5680a38-8ce2-4a28-93e4-db00fac4a2f9", "bearer", "39767", "basic openid");

  }

  public MultiValueMap<String, String> queryParams() {

    MultiValueMap<String, String> queryParams = new LinkedMultiValueMap<>();

    queryParams.add(CommerceConnectorConstants.AUTHORIZATION_CLIENT_ID, "asm");

    queryParams.add(CommerceConnectorConstants.AUTHORIZATION_CLIENT_SECRET, "12341234");

    queryParams.add(CommerceConnectorConstants.AUTHORIZATION_GRANT_TYPE,
        CommerceConnectorConstants.REQUEST_HEADER_AUTHORIZATION_GRANT_TYPE);

    queryParams.add(CommerceConnectorConstants.AUTHORIZATION_USERNAME, "abc@test.com");

    return queryParams;

  }


 @Test
  public void testAccessToken() throws Exception {

    System.out.println("Test executed ->>>>>>>>>>>> "+webTestClient);
    when(authenticationProvider.getUserAccessToken(any(), any())).then((res) -> Mono.just(getAccessToken()));

    this.webTestClient.post().uri(builder -> builder.path("/authorizationserver/oauth/token")
        .queryParams(queryParams())
        .build())
            .header(CommerceConnectorConstants.TENANT_ID, "4370be48-6605-41da-89c5-dfc8945498ab")
            .header(CommerceConnectorConstants.CORRELATION_ID, "4370be48-6605-41da-89c5-dfc8945498ab")
            .header(CommerceConnectorConstants.TENANT_USER_ID, "6e9dd5ef-0dbd-4a76-83aa-75cb85732851")
            .accept(MediaType.APPLICATION_JSON_UTF8)
            .exchange()
            .expectStatus()
            .isOk();
  }
}

POM.xml（代码块）：-

<parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>2.0.3.RELEASE</version>
        <relativePath /> <!-- lookup parent from repository -->
    </parent>

        <dependency>
            <groupId>org.springframework.boot</groupId>

            <artifactId>spring-boot-starter-test</artifactId>

        </dependency>

我尝试了所有方法，但无法找出问题所在。 请指教。谢谢
