在集成测试中重写bean

Question

@Configuration
public class RestTemplateProvider {

    private static final int DEFAULT_SERVICE_TIMEOUT = 5_000;

    @Bean
    public RestTemplate restTemplate(){
        return new RestTemplate(buildClientConfigurationFactory());
    }

    private ClientHttpRequestFactory buildClientConfigurationFactory() {
        HttpComponentsClientHttpRequestFactory factory = new HttpComponentsClientHttpRequestFactory();
        factory.setReadTimeout(DEFAULT_SERVICE_TIMEOUT);
        factory.setConnectTimeout(DEFAULT_SERVICE_TIMEOUT);
        return factory;
    }
}

@RunWith(SpringJUnit4ClassRunner.class)
@SpringApplicationConfiguration(classes = TestConfiguration.class)
@WebAppConfiguration
@ActiveProfiles("it")
public abstract class IntegrationTest {}

@Configuration
@Import({Application.class, MockRestTemplateConfiguration.class})
public class TestConfiguration {}

最后是MockRestTemplateConfiguration

@Configuration
public class MockRestTemplateConfiguration {

    @Bean
    public RestTemplate restTemplate() {
        return Mockito.mock(RestTemplate.class)
    }
}

从Spring Boot1.4.x开始，就有了使用@mockbean注释伪造Spring bean的选项。

对评论的反应：

要将上下文保留在缓存中，不要使用@dirtiescontext，而是使用@contextconfiguration(name=“ContextTithFakeBean”），它将创建单独的上下文，同时将默认上下文保留在缓存中。Spring会在缓存中保留这两个上下文（或者你有多少上下文）。
