Spring：如何将@RestClientTest 与带有@Qualifier

Question

我已经更改了一个使用 a 的 Spring Boot (2.1.4) 服务RestTemplate来使用@Qualifier. 现在我的 Test (with @RestClientTestand @AutoConfigureWebClient) 失败了，因为它无法解析 bean。我该如何解决？配置：  @Bean  @Qualifier("eureka")  @LoadBalanced  RestTemplate eurekaRestTemplate() {服务：  public ClarkClient(      @Qualifier("eureka") RestTemplate restTemplate, ClarkConfiguration configuration)      throws URISyntaxException {考试：@ExtendWith({SpringExtension.class, MockitoExtension.class})@RestClientTest({CastorClient.class, CastorConfiguration.class})@AutoConfigureWebClient(registerRestTemplate = true)class CastorClientWebTest {  @Autowired  private CastorClient cut;  @Autowired  private MockRestServiceServer server;错误：[2019-04-16T14:02:22,614] [WARN ] [            ....AnnotationConfigApplicationContext] [refresh 557] : Exception encountered during context initialization - cancelling refresh attempt: org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'castorClient' defined in file [/home/martinsc/java/routing/route-testing-batch-manager/out/production/classes/com/tyntec/routetesting/batchmanager/core/clients/CastorClient.class]: Unsatisfied dependency expressed through constructor parameter 0; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type 'org.springframework.web.client.RestTemplate' available: expected at least 1 bean which qualifies as autowire candidate. Dependency annotations: {@org.springframework.beans.factory.annotation.Qualifier(value=eureka)}

Answer 1

您不应该使用(registerRestTemplate = true)它，因为它会为您创建一个不是您使用的 RestTemplate bean。

如果在您的 中声明了您的合格 RestTemplate bean，请CastorConfiguration尝试使用@Import(CastorConfiguration.class)

Answer 2

对我有用的解决方案：（@AutoConfigureWebClient没有(registerRestTemplate = true)）。在@TestConfiguration类中创建一个RestTemplate具有权限的 bean@Qualifier

@Bean

@Qualifier("eureka")

public RestTemplate eurekaRestTemplate() {

  return new RestTemplate();

}

将其注入测试类

@Autowired

@Qualifier("eureka")

private RestTemplate restTemplate;

现在我们需要将它连接到MockRestServiceServer. 我们通过@BeforeEach

private MockRestServiceServer server;

@BeforeEach

  void setUp () {

    server = MockRestServiceServer.bindTo(restTemplate).build();

  }
