java - JUnits 中 @RepositoryRestResource 的 url 出现 404

标签 java rest spring-boot spring-data-jpa junit4

JUnits 缺少某些内容或配置错误 - 我找不到。 在 Junits 中获取 404 而不是 200。 http://localhost:8080/app 上的应用程序显示预期响应。

最佳答案

@WebMvcTest 应该仅用于 Controller 。因此，@RepositoryRestResource 类未初始化。

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

其他类似的测试实用程序注释:

@WebMvcTest - 用于 Controller

@JsonTest - 用于 JSON 编码和解码

@DataJpaTest - 用于存储库

@RestClientTests - 用于 REST 客户端

@SpringBootTest - 对于其他一切
