java - Spring Boot 1.4.2 @WebMvcTest 返回状态 404

Question

我正在使用 Spring Boot 1.4.2 和 Jersey (jax-rs) 创建一个 REST Controller 。我遵循了有关如何测试 REST Controller 的文档 (Testing the Spring MVC slice)。但是我的测试返回 404，我似乎无法找出原因。这里的 Controller 被简化了，但问题依然存在。

我的问题是如何在运行测试时获取200状态？

HealthController.java

@Controller
@Path("/health")
public class HealthController {
    @GET
    @Produces(MediaType.APPLICATION_JSON)
    public Health health() {
        return Health.up().build();
    }
}

运行服务器并进行查询给了我这个

%> curl -i http://localhost:8080/health
HTTP/1.1 200 
X-Application-Context: application
Content-Type: application/json
Content-Length: 21
Date: Sun, 27 Nov 2016 15:22:30 GMT

{
  "status" : "UP"
}% 

HealthControllerTest.java

@RunWith(SpringRunner.class)
@WebMvcTest(HealthController.class)
public class HealthControllerTest {

    @Autowired
    private MockMvc mockMvc;

    @Test
    public void health() throws Exception {
        mockMvc.perform(get("/health").accept(MediaType.APPLICATION_JSON))
                .andExpect(status().isOk()); // 200 expected
    }
}

这是我在运行测试时得到的结果

根据 @Path 和 @GET 注释判断您使用的是 JAX-RS 而不是 Spring MVC。 @WebMvcTest专门用于测试使用Spring MVC实现的web slice。它过滤掉不是 Spring MVC Controller 的组件，因此它不能与使用 JAX-RS 实现的 Web API 一起使用。
