Question

我有一个像这样的控制器：

@RestController
@RequestMapping('/v1/document')
class DocumentV1Controller {
  @PutMapping
  HttpEntity<Document> newdoc(
    @RequestHeader Map<String, String> headers, @RequestParam('document') MultipartFile multipartFile) {
  }
}

我想使用Spring MVC Test和Spock测试它，但我无法弄清楚如何构建一个MockMultipartHttpServletRequestBuilder将HttpMethod从POST更改为PUT请求。

这是Spock规范：

class DocumentV1ControllerSpec extends BaseControllerSpec {
  Should 'test and document good request on /v1/document endpoint'() {
    given:
      File file = new File('./src/test/resources/demoC.csv')
      MockMultipartFile multipartFile = new MockMultipartFile('file',file.getBytes())
    when:
      ResultActions result = mockMvc.perform(fileUpload('/v1/document')
        .file(multipartFile))
    then:
      result.andExpect(status().isCreated())
  }
}

我得到的错误是：

java.lang.AssertionError: Status expected:<201> but was:<405>
at org.springframework.test.util.AssertionErrors.fail(AssertionErrors.java:60)
at org.springframework.test.util.AssertionErrors.assertEquals(AssertionErrors.java:89)
at org.springframework.test.web.servlet.result.StatusResultMatchers$10.match(StatusResultMatchers.java:664)
at org.springframework.test.web.servlet.MockMvc$1.andExpect(MockMvc.java:171)
at gus.rest.api.v1.DocumentV1ControllerSpec.test and document good request on /v1/document endpoint(DocumentV1ControllerSpec.groovy:61)

我该怎么做才能让它发挥作用？

我不是spock方面的专家，但是现在不推荐使用Spring {5. *版本）使用方法fileUpload。

有一种方法可以将MockMultipartHttpServletRequestBuilder的默认POST方法更改为PUT：

class DocumentV1ControllerSpec extends BaseControllerSpec {
  Should 'test and document good request on /v1/document endpoint'() {
    given:
      File file = new File('./src/test/resources/demoC.csv')
      MockMultipartFile multipartFile = new MockMultipartFile('file', file.getBytes())

      MockMultipartHttpServletRequestBuilder multipart = (MockMultipartHttpServletRequestBuilder) multipart('/v1/document').with(request -> {
        request.setMethod(HttpMethod.PUT);
        return request;
      });
    when:
      ResultActions result = mockMvc.perform(multipart
        .file(multipartFile))
    then:
      result.andExpect(status().isCreated())
  }
}

诀窍是使用with(RequestPostProcessor postProcessor)修改请求并为其设置方法PUT。

如何使用Spring MVC和Spock使用PUT请求进行单元测试多部分？
