如何在 Spring Boot WebMvcTest 中设置上下文路径

我正在尝试从 Spring Boot 应用程序测试我的 Rest 控制器，并希望控制器在与生产中相同的路径下可用。

例如我有以下控制器：

@RestController
@Transactional
public class MyController {

    private final MyRepository repository;

    @Autowired
    public MyController(MyRepository repository) {
        this.repository = repository;
    }

    @RequestMapping(value = "/myentity/{id}",
        method = RequestMethod.GET,
        produces = MediaType.APPLICATION_JSON_VALUE)
    @ResponseBody
    public ResponseEntity<Resource<MyEntity>> getMyEntity(
            @PathVariable(value = "id") Long id) {
        MyEntity entity = repository.findOne(id);

        if (entity == null) {
            return new ResponseEntity<>(HttpStatus.NOT_FOUND);
        }

        return new ResponseEntity<>(entity, HttpStatus.OK);
    }
}

在我的application.yml我已经配置了应用程序的上下文路径：

server:
  contextPath: /testctx

我对该控制器的测试如下：

@RunWith(SpringRunner.class)
@WebMvcTest(controllers = MyController.class, secure=false)
public class MyControllerTest {

    @Autowired
    private MyRepository repositoryMock;

    @Autowired
    private MockMvc mvc;

    @Test
    public void testGet() throws Exception {
        MyEntity entity = new MyEntity();
        entity.setId(10L);
        when(repositoryMock.findOne(10L)).thenReturn(entity);

        MockHttpServletResponse response = this.mvc.perform(
            MockMvcRequestBuilders.get("/testctx/myentity/10"))
            .andReturn().getResponse();
        assertEquals(response.getStatus(), 200);
    }

    @TestConfiguration
    public static class TestConfig {
        @Bean
        MyRepository mockRepo() {
            return mock(MyRepository.class);
        }
    }
}

此测试失败，因为调用的状态代码为 404。如果我打电话/myentity/10有用。不幸的是，其余调用是由 CDC-Test-Framework (pact) 发起的，因此我无法更改请求的路径（包含上下文路径）/testctx）。那么有没有办法告诉 spring boot test 在测试期间也使用定义的上下文路径启动其余端点？

你可以尝试：

@WebMvcTest(controllers = {MyController.class})
@TestPropertySource(locations="classpath:application.properties")
class MyControllerTest {

    @Autowired
    protected MockMvc mockMvc;
    
    @Value("${server.servlet.context-path}")
    private String contextPath;
    
    @BeforeEach
    void setUp() {
        assertThat(contextPath).isNotBlank();
        ((MockServletContext) mockMvc.getDispatcherServlet().getServletContext()).setContextPath(contextPath);
    }
    
    protected MockHttpServletRequestBuilder createGetRequest(String request) {
        return get(contextPath + request).contextPath(contextPath)...
    }
