健康指标Spring集成测试NotFound失败

Question

我想为自定义的 HealthIndicator 编写一个简单的测试，它在它自己的模块中定义，与 Spring 应用程序的模块分开。 HealthIndicator 非常简单：

@Component
public class MyHealthIndicator implements HealthIndicator {
    public Health health() {
        return Health.up().withDetail("my-health", "okay").build();
    }  
}

这是测试：

@WebAppConfiguration
@ContextConfiguration(classes = {TestConfiguration.class, MyHealthIndicator.class})
@ExtendWith(SpringExtension.class)
class MyHealthIndicatorTests {
    @Autowired
    private MockMvc mockMvc;

    @Test
    public void healthTest() throws Exception {
        mockMvc.perform(get("/management/health")).andExpect(status().isOk());
    }
}

这是简单的测试配置：

@Configuration
@EnableWebMvc
@ImportAutoConfiguration(classes = {HealthEndpointAutoConfiguration.class, MockMvcAutoConfiguration.class})
@TestPropertySource(properties = {"debug:true", "management.endpoints.enabled-by-default:true", 
    "management.endpoints.web.base-path:/management", "management.endpoints.web.exposure.include=health"})
public class TestConfiguration {
}

健康端点的测试返回 404 - Not Found。

在日志中，我看到 TestDispatcherServlet 没有健康端点的映射：

12:48:38.309 [main] WARN org.springframework.web.servlet.PageNotFound - No mapping for GET /management/health

但是为什么？

在日志中，我还看到实际创建了 HealthEndpoint：

12:48:38.013 [main] DEBUG org.springframework.beans.factory.support.DefaultListableBeanFactory - Creating shared instance of singleton bean 'healthEndpoint'

但 TestDispatcherServlet 中的映射似乎没有配置。如何启用映射？

请注意：我想在没有 SpringBootApplication 的情况下测试我的健康指标。这根本不可能吗？

编辑： POM 没有什么特别之处：

Answer 1

在定义测试属性源时看起来像是一个错字。

代替

management.endpoints.web.base-path:/management
management.endpoints.enabled-by-default:true

应该是

management.endpoints.web.base-path=/management
management.endpoints.enabled-by-default=true
