SpringBoot2 Webflux - WebTestClient返回“内容尚未可用”

提问于

我正在尝试编写一些测试并面对以下异常,当我尝试 post 一个字节数组体:

错误

java.lang.AssertionError: Status expected:<201> but was:<404>

> POST /api/foo
> WebTestClient-Request-Id: [1]
> Content-Length: [246444]

Content not available yet

< 404 Not Found
< 

Content not available yet

我的Test类如下:

@AutoConfigureWebTestClient
@RunWith(SpringRunner.class)
@FixMethodOrder(NAME_ASCENDING)
@SpringBootTest(classes = Application.class)
public class ControllerTest {

  @Inject
  protected WebTestClient webClient;

  @Test
  public void testPostFile() throws Exception {

    byte[] bytes;

    try (InputStream is = getClass().getClassLoader().getResourceAsStream("static/binary-file.docx")) {
      bytes = IOUtils.toByteArray(is);
    }

    webClient
      .post()
      .uri("/api/foo")
      .body(BodyInserters.fromResource(new ByteArrayResource(bytes))))
      .exchange()
      .expectStatus().isCreated();

  }

}

是否有人面临同样的问题,似乎无法正确加载资源

EDIT:

我的应用程序Bootstrap类

@EnableWebFlux
@Configuration
@ComponentScan(basePackageClasses = SBApplication.class)
@EnableAutoConfiguration
public class SBApplication {

    /**
     * Spring Boot Main Entry
     *
     * @param args command line arguments
     * @throws Exception on failure
     */
    public static void main(String[] args) throws Exception {

        ConfigurableApplicationContext ctx = new SpringApplicationBuilder()
                .sources(SBApplication.class)
                .run(args);
    }
}

我的控制器类:

@RestController
@RequestMapping("/api")
public class SBController {

  // ...

  @RequestMapping(
    method = POST,
    path = "{name}"
  )
  public Mono<ResponseEntity> store(
            @PathVariable("name") String name,
            @RequestBody byte[] body) {

    // do stuff

    return Mono.just(
      ResponseEntity
          .status(HttpStatus.CREATED)
          .build()
    );

  }

}

    最终,问题是我的控制器是通过注释配置的 . WebTestClient只能识别通过 RouterFunction 路由的映射 endpoints .

    为了测试配置了注释的Controller,例如我的示例,您需要初始化MockMvc并使用相应的注释 @AutoConfigureMockMvc

    最后,由于使用了 reactor-core ,我们需要使用 MockMvcRequestBuilders.asyncDispatch 如下:

    @AutoConfigureMockMvc
    @RunWith(SpringRunner.class)
    @FixMethodOrder(NAME_ASCENDING)
    @SpringBootTest(classes = Application.class)
    public class ControllerTest {
    
      @Inject
      protected MockMvc mockMvc;
    
      @Test
      public void testPostFile() throws Exception {
    
        byte[] bytes;
    
        try (InputStream is = getClass().getClassLoader().getResourceAsStream("static/binary-file.docx")) {
          bytes = IOUtils.toByteArray(is);
        }
    
        MvcResult result = mockMvc.perform(
                    post("/api/foo")
                            .content(bytes)
            )
                    .andExpect(request().asyncStarted())
                    .andReturn();
    
            mockMvc.perform(asyncDispatch(result))
                    .andExpect(status().isCreated());
    
      }
    
    }
    

    最后一切都按预期工作!
