【中文标题】Spring Boot 模拟创建的 POST 响应【英文标题】:Spring boot mock CREATED POST response 【发布时间】:2018-10-21 07:11:27 【问题描述】:

对 spring-boot 完全陌生。

我正在尝试为我的 POST 方法编写一个测试,该方法返回一个带有资源路径的 CREATED 响应。我遇到了各种各样的问题,因为我认为这些问题非常简单。在下面的代码中是我当前的测试类,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());
    

知道如何正确模拟我的回复吗?谢谢

【问题讨论】:

你需要在你的maven依赖中添加spring-test,例如:org.springframeworkspring-test2.5 测试 我正在使用 sping-boot 并且我已经在导入:org.springframework.bootspring-boot-starter-test1.5.10.RELEASE test 你能发布你的堆栈跟踪错误吗? @guilhebl 将堆栈跟踪添加到问题 【参考方案1】:

我不确定您要做什么以及为什么要模拟 Response。当您为您的资源运行测试时,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。但在您的情况下,您使用的是 Jersey(我假设,基于您帖子中的 jax-rs 标签。

就客户端库而言,您可以使用Jersey/JAX-RS Client API,也可以使用Spring Boot 的TestRestTemplate,就像在official Spring Boot/Jersey sample project 中一样。要检查 POST/Created 资源的已创建 URI,您应该检查响应中的 Location 标头。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

那么(如果您使用 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。还要摆脱您拥有的 jersey-core 依赖项。有关完整示例,请参见上面的链接项目。

【讨论】:

在进行发布请求时导致InjectionManagerFactory not found。调查一下 它与您在 Jersey 中使用的依赖版本有关。这个问题从 2.26 开始,要修复它,您需要添加 jersey-hk2 依赖项。 调查提到这一点的***.com/questions/44088493/…。但是,我在ClientBuilder.newClient(); 上回到java.lang.ClassNotFoundException: org.glassfish.jersey.client.JerseyClientBuilder。我不知道为什么它这么乱。如果不让它变得更容易,那么 spring-boot 的意义何在:/ 您需要使用spring-boot-starter-jersey。并摆脱jersey-core。看我链接的官方例子。 Here's 另一个简单的应用程序设置(您只需添加 spring-boot-starter-test 即可)。这里是docs。其实很简单。如果您不知道自己在做什么并且阅读了错误的学习资源,这只会变得复杂。【参考方案2】:

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>
        </dependency>

        <dependency>
            <groupId>org.glassfish.jersey.core</groupId>
            <artifactId>jersey-common</artifactId>
            <version>2.27</version>
            <scope>provided</scope>
