RestClientTest 注解无法自动配置 RestTemplate

Question

我有一个具有 RestTemplate 依赖项的类

@Service
public class SwiftAPIPushHandler {

    private final ObjectMapper objectMapper;

    private final RestTemplate restTemplate;

    @Value("${app.swift.host}")
    private String swiftHost;

    @Value("${app.swift.client.secret}")
    private String clientSecret;

    public SwiftAPIPushHandler(@Autowired RestTemplate restTemplate,
                                     @Autowired ObjectMapper objectMapper) {
        this.restTemplate = restTemplate;
        this.objectMapper = objectMapper;
    }

    @ServiceActivator
    public Map<String, Object> outboundSwiftPushHandler(Map<String, Object> payload,
                                                              @Header("X-UPSTREAM-WEBHOOK-SOURCE") String projectId) throws JsonProcessingException {
        // HTTP POST Request from RestTemplate here 
    }
}

在测试中我希望使用

@RestClientTest

自动配置

RestTemplate

@RestClientTest
@SpringJUnitConfig(classes = {SwiftAPIPushHandler.class})
public class SwiftAPIPushHandlerTest {

    @Autowired
    SwiftAPIPushHandler apiPushHandler;

    @Test
    public void testSwiftApiPush(
            @Value("classpath:sk-payloads/success-response.json") Resource skPayload) throws IOException {
                // blah blah blah
            }
}

但是测试失败，无法找到 RestTemplate 错误的自动装配候选者。

Description:

Parameter 0 of constructor in com.swift.cloud.transformation.engine.SwiftAPIPushHandler required a bean of type 'org.springframework.web.client.RestTemplate' that could not be found.

The injection point has the following annotations:
    - @org.springframework.beans.factory.annotation.Autowired(required=true)


Action:

Consider defining a bean of type 'org.springframework.web.client.RestTemplate' in your configuration.

Answer 1

在

@RestClientTest

的文档中您可以阅读：

如果你测试的bean不使用RestTemplateBuilder而是直接注入RestTemplate，你可以添加@AutoConfigureWebClient(registerRestTemplate = true)。

因此，如果您添加到测试类

@AutoConfigureWebClient(registerRestTemplate = true)

，它应该正确注入restTemplate。

@RestClientTest
@AutoConfigureWebClient(registerRestTemplate = true)
@SpringJUnitConfig(classes = {SwiftAPIPushHandler.class})
public class SwiftAPIPushHandlerTest {

另一种方法是在您的服务中注入

RestTemplateBuilder

，在这种情况下，您在测试中不需要

@AutoConfigureWebClient

注释：

@Autowired
public SwiftAPIPushHandler(RestTemplateBuilder restTemplateBuilder, ObjectMapper objectMapper) {
    this.restTemplate = restTemplateBuilder.build();
    this.objectMapper = objectMapper;
}

Answer 2

您需要使用resttemplate builder配置resttemplate 将其添加到您的项目中

@Configuration
public class RestTemplateConfig {
    @Bean
    public RestTemplate restTemplate(RestTemplateBuilder builder) {
        Duration duration = Duration.ofMinutes(1);
        return builder.setConnectTimeout(duration).setReadTimeout(duration).build();
    }
}
