Question

我使用Spring Boot 1.4.2和Jersey（jax-rs）来创建REST控制器。我已经按照文档介绍了如何测试REST控制器（Testing the Spring MVC slice）。但我的测试返回404，我似乎无法找出原因。这里的控制器已经过简化，但问题仍然存在。

我的问题是如何在运行测试时获得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会给我

%> 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

Answer 1

通过@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切片。它过滤掉了不是Spring MVC控制器的组件，因此它不能使用JAX-RS实现的Web API。

当我查看您的Controller类时，它有点令人困惑。您正在使用@Controller，然后使用@Path和@GET注释，这意味着您正在使用Jersey。我建议改用@Component。虽然@Controller延伸@Component但仍然......

无论如何，您应该使用org.springframework.boot.test.web.client.TestRestTemplate来测试您的其余资源。例如

@RunWith(SpringRunner.class)
@SpringBootTest
public class SpringBootApplicationTests {


    @Autowired
    private TestRestTemplate restTemplate;

    @Test
    public void contextLoads() {
        final ResponseEntity<Health> entity = this.restTemplate.getForEntity("/health", Health.class);
        assertThat(entity.getStatusCode()).isEqualTo(OK);
    }

}

这应该适合你。

我添加了pom.xml，它显示了你需要添加到pom.xml的依赖项

你可以看到我同时使用弹簧mvc，spring-boot-starter-web和球衣spring-boot-starter-jersey。请记住，您需要添加一个@Configuration类来注册您的Jerse休息端点。这是一个样本类

import javax.ws.rs.ApplicationPath;

import org.glassfish.jersey.server.ResourceConfig;
import org.springframework.context.annotation.Configuration;

/**
 * @author Iftikhar Ul Hassan
 */

@Configuration
@ApplicationPath("/rest")
public class JerseyConfig extends ResourceConfig {

    public JerseyConfig() {
        packages("package.path.where.HealthController.resides");

    }
}

现在，您可以在/rest/**

下为您的球衣休息点提供服务

Spring Boot 1.4.2 @WebMvcTest返回状态404
