如何在 JUnit 5 中使用@RestTemplateClient？

Question

我使用 spring boot 2.1.7.RELEASE 和 junit 5。不幸的是，@RestClientTest 有问题，因为我收到 java.lang.IllegalStateException: Unable to use auto-configured MockRestServiceServer since MockServerRestTemplateCustomizer has not being bound to a RestTemplate。您对如何正确配置有任何想法吗？类似的代码在 junit 4 中完美运行。源代码基于文档https://docs.spring.io/spring-boot/docs/current/reference/html/boot-features-testing.html。源代码：@RestClientTest(RemoteVehicleDetailsService.class)public class ExampleRestClientTest {    @Autowired    private RemoteVehicleDetailsService service;    @Autowired    private MockRestServiceServer server;    @Test    public void getVehicleDetailsWhenResultIsSuccessShouldReturnDetails()            throws Exception {        this.server.expect(requestTo("/greet/details"))                .andRespond(withSuccess("hello", MediaType.TEXT_PLAIN));        String greeting = this.service.callRestService();        assertThat(greeting).isEqualTo("hello");    }

Answer 1

我用最后一个 spring boot 2.1.7 和 junit 5 测试了你的案例，一切正常。请尝试 ：

application.properties（我使用了 h2 内存数据库）：

spring.datasource.url=jdbc:h2:mem:testdb

spring.datasource.driverClassName=org.h2.Driver

spring.datasource.username=sa

spring.datasource.password=password

spring.jpa.database-platform=org.hibernate.dialect.H2Dialect

FooService.java :

@Service

public class FooService {

    private final RestTemplate restTemplate;

    public FooService(RestTemplateBuilder restTemplateBuilder) {

        this.restTemplate = restTemplateBuilder.build();

    }

    public String getIndex() {

        String result = restTemplate.getForObject("http://localhost:8080", String.class);

        System.out.println("index: " + result);

        return result;

    }

}

FooServiceTest.java :

@RestClientTest(FooService.class)

public class FooServiceTest {

    @Autowired

    private FooService service;

    @Autowired

    private MockRestServiceServer server;

    @Test

    public void testIndex() throws Exception {

        this.server.expect(requestTo("http://localhost:8080")).andRespond(withSuccess("hello", MediaType.TEXT_PLAIN));

        String greeting = this.service.getIndex();

        assertEquals(greeting, "hello");

    }

}

Answer 2

spring MockMvc 会为你工作吗？

@Autowired

private MockMvc mockMvc;

public void test() {

    this.mockMvc.perform(get("/form")

            .header(AUTHORIZATION, authHeader))

            .andDo(print())

            .andExpect(status().isOk());

}
