Я выполняю миграцию JDK8 на JDK11, поэтому я обновляю springboot до 2.2.4.RELEASE
+ и добавляю:
<dependency>
<groupId>com.fasterxml.jackson.dataformat</groupId>
<artifactId>jackson-dataformat-xml</artifactId>
</dependency>
Я компилирую в java 8.
Контроллер:
@RequestMapping(value = "/{model}/nbLines", method = RequestMethod.GET, consumes = MediaType.ALL_VALUE, produces = { MediaType.APPLICATION_XML_VALUE, MediaType.APPLICATION_JSON_VALUE })
public ResponseEntity<Integer> getNbLines(@PathVariable String model) {
LOGGER.info("getNbLines : model[{}]", model);
Integer nbLines = modelService.getNbLines(model);
return Optional.ofNullable(nbLines).map(result -> new ResponseEntity<>(result, HttpStatus.OK)).orElse(new ResponseEntity<>(HttpStatus.NO_CONTENT));
}
My JSON curl:
$ curl -s --header "Принять: application / json" http://localhost: 8084 / noraui / api / hello / nbLines
8
My XML curl:
$ curl -s --header "Принять: application / xml" http://localhost : 8084 / noraui / api / hello / nbLines
<Integer>8</Integer>
Мой модульный тест (ОК с JDK8 , но не с JDK11 ):
@Test
public void getHelloNbLines() {
ResponseEntity<Integer> entity = new RestTemplate().getForEntity("http://localhost:" + port + "/noraui/api/hello/nbLines", Integer.class);
assertThat(entity.getStatusCode()).isEqualTo(HttpStatus.OK);
assertThat(entity.getBody()).isEqualTo(8);
}
Я пытаюсь с:
@Test
public void getHelloNbLines() {
MultiValueMap<String, String> headers = new LinkedMultiValueMap<>();
headers.add("Content-Type", "application/json");
ResponseEntity<Integer> entity = new RestTemplate().exchange("http://localhost:" + port + "/noraui/api/hello/nbLines", HttpMethod.GET, new HttpEntity<Object>(headers), Integer.class);
assertThat(entity.getStatusCode()).isEqualTo(HttpStatus.OK);
assertThat(entity.getBody()).isEqualTo(8);
}
Моя ошибка:
[ERROR] getHelloNbLines(com.github.noraui.datas.web.services.rest.NoraUiDatasControllerTests) Time elapsed: 0.135 s <<< FAILURE!
