我知道类似的问题已经在这里出现了几次,但是根据建议的修复并没有解决我的问题。
我有一个带有以下端点的简单控制器:
@RequestMapping(method = RequestMethod.POST)
public ResponseEntity<String> singleFileUpload(@RequestParam("file") MultipartFile file) {
log.debug("Upload controller - POST: {}", file.getOriginalFilename());
// do something
}
我正在尝试使用Spring TestRestTemplate
为它编写集成测试,但我的所有尝试都以400 - Bad Request
结束(没有日志说明控制台出了什么问题)。
控制器内的日志没有被击中,因此在到达之前失败了。
请你看一下我的测试并建议我做错了什么?
@Test
public void testUpload() {
// simulate multipartfile upload
ClassLoader classLoader = getClass().getClassLoader();
File file = new File(classLoader.getResource("image.jpg").getFile());
MultiValueMap<String, Object> parameters = new LinkedMultiValueMap<String, Object>();
parameters.add("file", file);
HttpHeaders headers = new HttpHeaders();
headers.setContentType(MediaType.MULTIPART_FORM_DATA);
HttpEntity<MultiValueMap<String, Object>> entity = new HttpEntity<MultiValueMap<String, Object>>(parameters, headers);
ResponseEntity<String> response = testRestTemplate.exchange(UPLOAD, HttpMethod.POST, entity, String.class, "");
// Expect Ok
assertThat(response.getStatusCode(), is(HttpStatus.OK));
}

我尝试了以下内容:
@Test
public void testUpload() {
LinkedMultiValueMap<String, Object> parameters = new LinkedMultiValueMap<String, Object>();
parameters.add("file", new org.springframework.core.io.ClassPathResource("image.jpg"));
HttpHeaders headers = new HttpHeaders();
headers.setContentType(MediaType.MULTIPART_FORM_DATA);
HttpEntity<LinkedMultiValueMap<String, Object>> entity = new HttpEntity<LinkedMultiValueMap<String, Object>>(parameters, headers);
ResponseEntity<String> response = testRestTemplate.exchange(UPLOAD, HttpMethod.POST, entity, String.class, "");
// Expect Ok
assertThat(response.getStatusCode(), is(HttpStatus.OK));
}
正如你所看到的,我使用org.springframework.core.io.ClassPathResource
作为文件的对象,而ti就像魅力一样
我希望它有用

FileSystemResource
,也可以使用 java.nio.file.Path
。
包裹:org.springframework.core.io.FileSystemResource
例如,您可以这样做:
new FileSystemResource(Path.of("src", "test", "resources", "image.jpg"))
完整代码示例:
@SpringBootTest(webEnvironment = SpringBootTest.WebEnvironment.RANDOM_PORT)
public class UploadFilesTest {
private final TestRestTemplate template;
@Autowired
public UploadFilesTest(TestRestTemplate template) {
this.template = template;
}
@Test
public void uploadFileTest() {
var multipart = new LinkedMultiValueMap<>();
multipart.add("file", file());
final ResponseEntity<String> post = template.postForEntity("/upload", new HttpEntity<>(multipart, headers()), String.class);
assertEquals(HttpStatus.OK, post.getStatusCode());
}
private HttpHeaders headers() {
HttpHeaders headers = new HttpHeaders();
headers.setContentType(MediaType.MULTIPART_FORM_DATA);
return headers;
}
private FileSystemResource file() {
return new FileSystemResource(Path.of("src", "test", "resources", "image.jpg"));
}
}
休息控制器:
@RestController
public class UploadEndpoint {
@PostMapping("/upload")
public void uploadFile(@RequestParam("file") MultipartFile file) {
System.out.println(file.getSize());
}
}
