java - JUnits中@RepositoryRestResource的URL上的404

JUnits缺少或配置错误-我找不到。
在Junits中获取404而不是200。 http://localhost:8080/app处的应用程序显示了预期的响应。

最佳答案

@WebMvcTest仅应用于Controllers。因此，@RepositoryRestResource类未初始化。

用@AutoConfigureMockMvc和@SpringBootTest替换它就可以了。

其他类似的Test Utility注释：

@WebMvcTest-用于控制器

@JsonTest-用于JSON封送和解组

@DataJpaTest-用于存储库

@RestClientTests-用于REST客户端

@SpringBootTest-其他
