java - JUnits 中@RepositoryRestResource 的 url 上的 404
问题描述
JUnits 缺少某些东西或配置错误 - 我找不到。在 Junits 中获得 a404而不是。200应用程序 http://localhost:8080/app显示了预期的响应。

解决方案
@WebMvcTest应该只用于Controllers. 因此，@RepositoryRestResource类没有被初始化。
用它代替它@AutoConfigureMockMvc并@SpringBootTest成功了。
其他类似的测试实用程序注释：
@WebMvcTest- 用于控制器
@JsonTest- 用于 JSON 编组和解组
@DataJpaTest- 对于存储库
@RestClientTests- 对于 REST 客户端
@SpringBootTest- 对于其他一切
