使用不处理多部分/表单数据的REST文档生成存根

我想使用REST文档自动生成WireMock存根。我想要匹配 multipart/form-data 通过使用 WireMockRestDocs.verify() 但我总是有例外 [wiremock did not match request] . 我的API有一个结合了两部分的方法:json对象和MultipartFile。怎么了?

spring-boot 2.0.6.RELEASE
spring-cloud-dependencies Finchley.SR2

控制器

@RestController
public class MultipartTestController {

    private final Log logger = LogFactory.getLog(getClass());

    @PostMapping("/test")
    public ResponseEntity<Void> postMultipart(@RequestPart("metadata") MetadataDTO metadataDTO, @RequestPart("file") MultipartFile multipartFile) {
        logger.info(metadataDTO);
        return ResponseEntity.noContent().build();
    }
}

试验

@RunWith(SpringRunner.class)
@SpringBootTest
@AutoConfigureRestDocs(outputDir = "target/generated-snippets")
@AutoConfigureMockMvc
public class DemoRestdocMultipartApplicationTests {

    @Autowired
    private MockMvc mockMvc;

    @Autowired
    private ObjectMapper objectMapper;

    @Test
    public void contextLoads() throws Exception {

        MetadataDTO metadataDTO = new MetadataDTO();
        metadataDTO.setName("test");

        MockMultipartFile file = new MockMultipartFile("file", "contract.pdf", MediaType.APPLICATION_PDF_VALUE, "pdfcontent".getBytes(StandardCharsets.UTF_8));
        MockMultipartFile metadata = new MockMultipartFile("metadata", "", MediaType.APPLICATION_JSON_VALUE, objectMapper.writeValueAsString(metadataDTO).getBytes(StandardCharsets.UTF_8));
        this.mockMvc.perform(fileUpload("/test")
                .file(file)
                .file(metadata))
                .andExpect(status().isNoContent())
                .andDo(verify()
                        .wiremock(
                                post(WireMock.urlPathEqualTo("/test"))
                                        .withHeader(HttpHeaders.CONTENT_TYPE, WireMock.containing(MediaType.MULTIPART_FORM_DATA_VALUE))
                                        .withMultipartRequestBody(
                                                aMultipart()
                                                        .withHeader("Content-Disposition", containing("name=file"))
                                                        .withHeader("Content-Type", WireMock.equalTo(MediaType.APPLICATION_PDF_VALUE))
                                                        .withBody(equalTo("pdfcontent"))
                                        )
                                        .withMultipartRequestBody(
                                                aMultipart()
                                                        .withHeader("Content-Disposition", containing("name=metadata"))
                                                        .withHeader("Content-Type", WireMock.containing(MediaType.APPLICATION_JSON_VALUE))
                                                        .withBody(WireMock.matchingJsonPath("$[?(@.name == 'test')]"))
                                        )
                        ).stub("testMultipart"))
                .andDo(document("testMultipart",
                        preprocessRequest(prettyPrint()),
                        requestParts(
                                partWithName("file").description("The file to upload"),
                                partWithName("metadata").description("metadata")
                        ),
                        requestPartFields("metadata",
                                fieldWithPath("name").description("name")
                        )
                        , dslContract()
                ));
    }
}
