Spring 引导模拟已创建 POST 响应
Spring boot mock CREATED POST response
对 spring-boot 完全陌生。
我正在尝试为我的 POST 方法编写一个测试，该方法 returns 响应 CREATED 和资源路径。对于我认为非常简单的事情，我遇到了各种各样的问题。在下面的代码中是我当前的测试 class，它似乎因
而崩溃
ClassNotFoundException
在我的方法的第一行。
@RunWith(SpringRunner.class)
@WebMvcTest(AResource.class)
public class AResourceTest {
@Autowired
private MockMvc mockMvc;
@MockBean
private AResource aResourceMock;
@Test
public void testPOST() throws Exception {
Response.ResponseBuilder created = Response.created(UriBuilder.fromPath("/123").build());
when(aResourceMock.create(123)).thenReturn(created.build());
mockMvc.perform(MockMvcRequestBuilders
.request(HttpMethod.POST, "/account")
.content("{\t\"id\": \"123\"}"))
.andExpect(MockMvcResultMatchers.status().isCreated());
}
}
知道如何正确地模拟我的回复吗？谢谢

我不确定您要做什么以及为什么要模拟 Response。当您 运行 对您的资源进行测试时，通常您想要做的是 运行 集成测试。这需要使用客户端库向端点发出实际请求。 MockMvc 仅在您使用 Spring MVC 作为 REST 框架时有效。但就您而言，您使用的是 Jersey（我假设，基于 post 中的 jax-rs 标记。
至于客户端库，可以使用Jersey/JAX-RS Client API or you can use Spring Boot's TestRestTemplate, like they do in the official Spring Boot/Jersey sample project。要检查为 POST/Created 资源创建的 URI，您应该做的是检查响应中的 Location header。这是在您执行 Response.created(URI) 时在服务器端设置的。例如，假设这是您的资源
@Path("customers")
public class CustomersResource {
@POST
@Consumes(MediaType.APPLICATION_JSON)
public Response createCustomer(Customer customer, @Context UriInfo uriInfo) {
int customerId = // create customer and get the resource id
UriBuilder builder = uriInfo.getAbsolutePathBuilder();
builder.path(Integer.toString(customerId));
return Response.created(builder.build()).build();
}
}
Jersey 会自动将 Location 设置为传递给 created()
的 URI 的值
然后（如果您使用的是 Jersey 客户端），那么您的测试可能类似于
@RunWith(SpringRunner.class)
@SpringBootTest(webEnvironment = SpringBootTest.WebEnvironment.RANDOM_PORT)
public class ExampleResourceTest {
@LocalServerPort
private int port;
private Client client = ClientBuilder.newClient();
@Test
public void testCustomerLocationOnPost() {
Customer customer = new Customer("Jane", "Doe");
URI resourceUri = UriBuilder.fromUri("http://localhost")
.port(port).path("api").path("customers").build();
Response response = client.target(resourceUri).request().post(Entity.json(customer));
// test that we get the correct status code
assertThat(response.getStatus())
.isEqualTo(Response.Status.CREATED.getStatusCode());
// test that the location header is correct.
assertThat(response.getHeaderString(HttpHeaders.LOCATION))
.isEqualTo(UriBuilder.fromUri(resourceUri).path("123").build().toString());
}
}
就依赖项而言，要将 Jersey 与 Spring Boot 一起使用，您需要使用 spring-boot-started-jersey 依赖项。同时摆脱你拥有的 jersey-core 依赖。有关完整示例，请参阅上面的链接项目。
尝试添加到您的 pom.xml：
<dependency>
<groupId>org.glassfish.jersey.core</groupId>
<artifactId>jersey-server</artifactId>
<version>2.27</version>
<scope>provided</scope>
