测试 POST 请求与 Spring 的 multipartfile
Test POST request with multipartfile with Spring
我有一个发送 post 请求的控制器,它运行良好并与客户端正确通信。但是,我无法在 JUnit 中对其进行测试。
控制器接收一个多部分文件,以及 2 个布尔参数(必需),并且仅接受“application/xls”作为内容类型。
为了进行测试,我正在模拟 multipartfile 和参数。但是,当我这样做时,出现以下错误:handler.RestExceptionHandler: Exception caught. Wrong file type;\n Import .xls or .xlsx file
(来自我的异常处理程序)。
@PostMapping(value = "/file",
consumes = MediaType.MULTIPART_FORM_DATA_VALUE,
produces = MediaType.TEXT_HTML_VALUE)
public ResponseEntity<InputStreamResource> parseMultipartFile(
@RequestParam MultipartFile multipartFile,
@RequestParam boolean hasOnlyOneSheet,
@RequestParam boolean hasBorders) throws IOException {
String fileContentType = multipartFile.getContentType();
if (mimeType.contains(fileContentType)) {
InputStream parsedFile = multipartFileToHtmlService.multipartFileToHtml(multipartFile, hasOnlyOneSheet, hasBorders);
InputStreamResource inputStreamResource = new InputStreamResource(parsedFile);
return ResponseEntity.ok(inputStreamResource);
} else {
throw new UnsupportedImportMediaTypeException("Wrong file type;\n Import .xls or .xlsx file");
}
}
这是我的测试:
@WebMvcTest
@RunWith(SpringRunner.class)
class HtmlExporterControllerTest {
@MockBean
MultipartFileToHtmlService multipartFileToHtmlService;
@MockBean
HtmlToHtmlServiceFactory htmlToHtmlServiceFactory;
@Autowired
MockMvc mockMvc;
@Test
public void parseMultipartFile_Should_Return_Ok() throws Exception {
MockMultipartFile mockMultipartFile = new MockMultipartFile(
"multipartFile",
"test.xls",
"application/x-xls",
"Hello World!".getBytes());
mockMvc.perform(MockMvcRequestBuilders.multipart("/file")
.file("multipartFile", mockMultipartFile.getBytes())
.param("hasOnlyOneSheet", "true")
.param("hasBorders", "true"))
.andExpect(status().isOk());
}
为了避免这个问题,我尝试将布尔值作为新 multipart/form-data 传递,如下所示:
@Test
public void parseMultipartFile_Should_Return_Ok() throws Exception {
MockMultipartFile mockMultipartFile = new MockMultipartFile(
"multipartFile",
"test.xls",
"application/x-xls",
"Hello World!".getBytes());
MockMultipartFile mockMultipartFile1 = new MockMultipartFile(
"hasBorders",
"",
"",
"true".getBytes());
MockMultipartFile mockMultipartFile2 = new MockMultipartFile(
"hasOnlyOneSheet",
"",
"",
"true".getBytes());
mockMvc.perform(MockMvcRequestBuilders.multipart("/file")
.file("multipartFile", mockMultipartFile.getBytes())
.file("hasOnlyOneSheet", mockMultipartFile1.getBytes())
.file("hasBorders", mockMultipartFile2.getBytes()))
.andExpect(status().isOk());
}
但是,我得到以下错误Failed to convert value of type 'org.springframework.mock.web.MockMultipartFile' to required type 'boolean';
再一次,请求有效,我也可以在 Postman 上执行,这里是 curl 请求:
curl --location --request POST 'http://localhost:8080/file' \
--form 'multipartFile=@/MyPath/test.xlsx' \
--form 'hasBorders=true' \
--form 'hasOnlyOneSheet=true'
为了帮助其他人,我通过添加一个真正的 excel sheet:
来解决它

MultipartFileToHtmlService multipartFileToHtmlService;

mockMvc.perform(MockMvcRequestBuilders.multipart("/file")
.file(mockMultipartFile)
