Maven 依赖

    <dependency>
        <groupId>com.squareup.okhttp3</groupId>
        <artifactId>mockwebserver</artifactId>
        <version>4.9.0</version>
        <scope>test</scope>
    </dependency>
我写的测试 
@SpringJUnitConfig(classes = {GithubApiService.class, WebClientConfiguration.class})
@EnableAutoConfiguration
public class GithubApiServiceTest {

    @Test
    public void testGithubResponseJsonToMapConversion(
            @Autowired GithubApiService service,
            @Value("classpath:github/commit-payload.json") Resource commitPayloadFile) throws IOException {

        final String COMMITS_URL = "/repos/Codertocat/Hello-World/commits/sha";

        //Stub response from Github Server
        String responseJson = new ObjectMapper().writeValueAsString(
                new String(Files.readAllBytes(Paths.get(commitPayloadFile.getFile().getAbsolutePath()))));
        MockWebServer server = new MockWebServer();
        server.enqueue(new MockResponse()
                               .addHeader("Content-Type", "application/json; charset=utf-8")
                               .setBody(responseJson)
                               .setResponseCode(OK.value()));
        server.start();
        // Get mock server's URL
        HttpUrl mockGithubUrl = server.url(COMMITS_URL);

        //Call API Service
        Map<String, Object> result = service.getCommitDetails(mockGithubUrl.toString()).block();

        //Expect return type is hashmap
        assertThat(result.get("sha")).isEqualTo("6dcb09b5b57875f334f61aebed695e2e4193db5e");

        server.shutdown();
    }
}
被测类 
@Service
@AllArgsConstructor(onConstructor = @__(@Autowired))
public class GithubApiService {

    @Autowired
    private final WebClient webClient;

    public Mono<Map<String, Object>> getCommitDetails(String commitsUrl) {
        return webClient.get()
                .uri(commitsUrl)
                .httpRequest(httpRequest -> {
                    HttpClientRequest reactorRequest = httpRequest.getNativeRequest();
                    reactorRequest.responseTimeout(Duration.ofSeconds(2));
                })
                .accept(APPLICATION_JSON)
                .retrieve()
                .bodyToMono(new ParameterizedTypeReference<Map<String, Object>>() {
                });
    }
}
运行测试时出现此错误

当我在 github 上浏览源 TaskRunner 时，我确实看到了 TaskRunner 类，但在我的 IDE 中搜索它时却没有看到。我在依赖声明中遗漏了什么吗？

最佳答案

您正在使用 OkHttp 3.14.9 和 MockWebServer 4.9.0。这些版本必须匹配。
