Okhhtp3模拟服务器java.lang.NoClassDefFoundError：okhttp3/internal/concurrent/TaskRunner$RealBackend
维护依赖
<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上浏览源代码TaskRunner时，我确实看到了TaskRunner类，但当我在IDE中搜索它时却看不到它。我是否在依赖项声明中遗漏了什么？

解决方案
您正在将OkHttp 3.14.9与MockWebServer 4.9.0一起使用。这些版本必须匹配。
