@Autowire MockMvc - Spring Data Rest [英] @Autowire MockMvc - Spring Data Rest

问题描述

给定存储库

public interface ResourceRepository extends CrudRepository<Resource, Long> { ... }

以下测试代码:

@WebMvcTest
@RunWith(SpringRunner.class)
public class RestResourceTests {

  @Autowired
  private MockMvc mockMvc;

  @Test
  public void create_ValidResource_Should201() {
    String requestJson = "...";

    mockMvc.perform(
      post("/resource")
        .content(requestJson)
        .contentType(MediaType.APPLICATION_JSON))
      .andExpect(status().isCreated()); // This fails with 404
  }

}

为了解决这个问题，我需要注入 WebApplicationContext 并手动创建 MockMvc 对象，如下所示:

In order to fix the issue, I need to inject the WebApplicationContext and manually create the MockMvc object as follows:

@SpringBootTest
@RunWith(SpringRunner.class)
public class RestResourceTests {

  private MockMvc mockMvc;

  @Autowired
  private WebApplicationContext webApplicationContext;

  @Before
  public void setup() {
    this.mockMvc = webAppContextSetup(webApplicationContext).build();
  }

有没有更简单的方法来实现这一目标?

Is there a simpler way to achieve this?

谢谢！

推荐答案

我想出了一个干净"的解决方案，但对我来说就像一个错误.

I figured out a "clean" solution, but it feels like a bug to me.

@SpringBootTest
@RunWith(SpringRunner.class)
@AutoConfigureMockMvc // <-- this is the fix 
public class RestResourceTests {

  @Autowired
  private MockMvc mockMvc; // <-- now injects with repositories wired.

我觉得这是一个错误的原因，@WebMvcTest 注释已经在被测类上放置了 @AutoConfigureMockMvc 注释.

The reason I feel like this is a bug, the @WebMvcTest annotation already places the @AutoConfigureMockMvc annotation on the class under test.

感觉 @WebMvcTest 并没有查看加载了 @RestRepository 的 Web 组件.

It feels like @WebMvcTest isn't looking at the web components loaded with @RestRepository.
