我正在尝试在我的Spring Boot应用程序的Integration-Test中使用TestRestTemplate向Spring Data REST存储库发出请求。
浏览器中的响应具有以下形式：
{ "links": [ { "rel": "self", "href": "http://localhost:8080/apiv1/data/users" }, { "rel": "profile", "href": "http://localhost:8080/apiv1/data/profile/users" }, { "rel": "search", "href": "http://localhost:8080/apiv1/data/users/search" } ], "content": [ { "username": "admin", "enabled": true, "firstName": null, "lastName": null, "permissions": [ ], "authorities": [ "ROLE_ADMIN" ], "accountNonExpired": true, "accountNonLocked": true, "credentialsNonExpired": true, "content": [ ], "links": [ { "rel": "self", "href": "http://localhost:8080/apiv1/data/users/1" }, { "rel": "myUser", "href": "http://localhost:8080/apiv1/data/users/1" }, { "rel": "mandant", "href": "http://localhost:8080/apiv1/data/users/1/mandant" } ] }, { "username": "dba", "enabled": true, "firstName": null, "lastName": null, "permissions": [ ], "authorities": [ "ROLE_DBA" ], "accountNonExpired": true, "accountNonLocked": true, "credentialsNonExpired": true, "content": [ ], "links": [ { "rel": "self", "href": "http://localhost:8080/apiv1/data/users/2" }, { "rel": "myUser", "href": "http://localhost:8080/apiv1/data/users/2" }, { "rel": "mandant", "href": "http://localhost:8080/apiv1/data/users/2/mandant" } ] }, { "username": "user", "enabled": true, "firstName": null, "lastName": null, "permissions": [ ], "authorities": [ "ROLE_USER" ], "accountNonExpired": true, "accountNonLocked": true, "credentialsNonExpired": true, "content": [ ], "links": [ { "rel": "self", "href": "http://localhost:8080/apiv1/data/users/3" }, { "rel": "myUser", "href": "http://localhost:8080/apiv1/data/users/3" }, { "rel": "mandant", "href": "http://localhost:8080/apiv1/data/users/3/mandant" } ] } ], "page": { "size": 20, "totalElements": 3, "totalPages": 1, "number": 0 } }
这是测试：
@RunWith(SpringRunner.class) @SpringBootTest(webEnvironment = WebEnvironment.RANDOM_PORT) @ActiveProfiles("unittest") public class MyUserRepositoryIntegrationTest { private static Logger logger = LoggerFactory.getLogger(MyUserRepositoryIntegrationTest.class); private static final int NUM_USERS = 4; private static final String USER_URL = "/apiv1/data/users"; @Autowired private TestRestTemplate restTemplate; @Test public void listUsers() { ResponseEntity<PagedResources<MyUser>> response = restTemplate.withBasicAuth("user", "user").exchange(USER_URL, HttpMethod.GET, null, new ParameterizedTypeReference<PagedResources<MyUser>>() { }); assertThat(response.getStatusCode()).isEqualTo(HttpStatus.OK); logger.debug("Res : " + response.getBody().toString()); assertThat(response.getBody().getContent().size()).isEqualTo(NUM_USERS); } @TestConfiguration public static class MyTestConfig { @Autowired @Qualifier("halJacksonHttpMessageConverter") private TypeConstrainedMappingJackson2HttpMessageConverter halJacksonHttpMessageConverter; @Bean public RestTemplateBuilder restTemplateBuilder() { return new RestTemplateBuilder().messageConverters(halJacksonHttpMessageConverter); } } }
问题是，我没有得到内容。有趣的是，元数据（分页信息）在那里。
我的TestConfig被检测到了，但我认为它没有使用’halJacksonHttpMessageConverter’（我从这里获得：https : //github.com/bijukunjummen/hateoas- sample/blob/master/src/test/java/univ/HALRestTemplateIntegrationTests。 java）。这就是为什么我使用“ messageConverters（）”而不是“ additionalMessageConverters（）”的原因（无济于事）。
这是日志：

覆盖restTemplate Bean的想法来自以下文档：https ://docs.spring.io/spring- boot/docs/current/reference/html/boot-features-testing.html#boot-features- rest-templates- 测试效用
有什么想法可以简单地进行一些REST调用并获得测试对象的答案？
我切换到MockMvc，一切正常：
import static org.hamcrest.Matchers.hasSize; import static org.springframework.test.web.servlet.request.MockMvcRequestBuilders.get; import static org.springframework.test.web.servlet.result.MockMvcResultMatchers.content; import static org.springframework.test.web.servlet.result.MockMvcResultMatchers.jsonPath; import static org.springframework.test.web.servlet.result.MockMvcResultMatchers.status; @RunWith(SpringRunner.class) @SpringBootTest(webEnvironment = WebEnvironment.RANDOM_PORT) @ActiveProfiles("unittest") public class MyUserRepositoryIntegrationTest { @Autowired WebApplicationContext context; @Autowired FilterChainProxy filterChain; MockMvc mvc; @Before public void setupTests() { this.mvc = MockMvcBuilders.webAppContextSetup(context).addFilters(filterChain).build(); @Test public void listUsers() throws Exception { HttpHeaders headers = new HttpHeaders(); headers.add(HttpHeaders.ACCEPT, MediaTypes.HAL_JSON_VALUE); headers.add(HttpHeaders.AUTHORIZATION, "Basic " + new String(Base64.encode(("user:user").getBytes()))); mvc.perform(get(USER_URL).headers(headers)) .andExpect(content().contentTypeCompatibleWith(MediaTypes.HAL_JSON)) .andExpect(status().isOk()) .andExpect(jsonPath("$.content", hasSize(NUM_USERS))); } }
编辑：
对于那些感兴趣的人，基于WellingtonSouza解决方案的替代解决方案：
尽管jsonpath非常强大，但我还没有找到一种使用MockMvc将JSON解组为实际对象的方法。
如果查看我发布的JSON输出，您会注意到，它不是默认的Spring DataRestHAL+JSON输出。我将属性data.rest.defaultMediaType更改为“ application / json”。这样，我也无法让特拉弗森工作。但是，当我停用它时，以下工作原理：
import static org.assertj.core.api.Assertions.assertThat; import static org.hamcrest.Matchers.hasSize; import static org.springframework.test.web.servlet.request.MockMvcRequestBuilders.get; import static org.springframework.test.web.servlet.result.MockMvcResultMatchers.content; import static org.springframework.test.web.servlet.result.MockMvcResultMatchers.jsonPath; import static org.springframework.test.web.servlet.result.MockMvcResultMatchers.status; import org.springframework.hateoas.MediaTypes; import org.springframework.hateoas.PagedResources; import org.springframework.hateoas.client.Hop; import org.springframework.hateoas.client.Traverson; import org.springframework.http.HttpHeaders; import org.springframework.security.crypto.codec.Base64; @RunWith(SpringRunner.class) @SpringBootTest(webEnvironment = WebEnvironment.RANDOM_PORT) @ActiveProfiles("unittest") public class MyUserRepositoryIntegrationTest { private static HttpHeaders userHeaders; private static HttpHeaders adminHeaders; @LocalServerPort private int port; @BeforeClass public static void setupTests() { MyUserRepositoryIntegrationTest.userHeaders = new HttpHeaders(); MyUserRepositoryIntegrationTest.userHeaders.add(HttpHeaders.ACCEPT, MediaTypes.HAL_JSON_VALUE); MyUserRepositoryIntegrationTest.userHeaders.add(HttpHeaders.AUTHORIZATION, "Basic " + new String(Base64.encode(("user:user").getBytes()))); MyUserRepositoryIntegrationTest.adminHeaders = new HttpHeaders(); MyUserRepositoryIntegrationTest.adminHeaders.add(HttpHeaders.ACCEPT, MediaTypes.HAL_JSON_VALUE); MyUserRepositoryIntegrationTest.adminHeaders.add(HttpHeaders.AUTHORIZATION, "Basic " + new String(Base64.encode(("admin:admin").getBytes()))); } @Test public void listUsersSorted() throws Exception { final ParameterizedTypeReference<PagedResources<MyUser>> resourceParameterizedTypeReference = // new ParameterizedTypeReference<PagedResources<MyUser>>() { }; final PagedResources<MyUser> actual = new Traverson(new URI("http://localhost:" + port + "/apiv1/data"), MediaTypes.HAL_JSON)// .follow(Hop.rel("myUsers").withParameter("sort", "username,asc"))// .withHeaders(userHeaders)// .toObject(resourceParameterizedTypeReference); assertThat(actual.getContent()).isNotNull().isNotEmpty(); assertThat(actual.getContent()// .stream()// .map(user -> user.getUsername())// .collect(Collectors.toList())// ).isSorted(); } }
（注意：可能不包含所有导入内容，因为我是从较大的Test Class复制而来的。）
“ .withParam”适用于模板化URL，即那些接受查询参数的URL。如果您尝试使用原始URL，它将失败，因为链接的字面意思是“ http：//[…] / users {option1，option2，…}”，因此格式不正确。
