带有HATEOAS PagedResources的Spring Boot的TestRestTemplate

带有HATEOAS PagedResources的Spring Boot的TestRestTemplate

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.enpre(("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.prec.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.enpre(("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.enpre(("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。
