 ### spring相关测试
+启动spring容器相关注解
+
+@SpringBootTest注解: 告诉Spring Boot查找一个主要的配置类（例如，一个带有@SpringBootApplication的类），并使用该类来启动Spring应用程序上下文。
+- webEnvironment=RANDOM_PORT: 使用webEnvironment = RANDOM_PORT可以使用随机端口启动服务器（用于避免测试环境中的冲突），并使用@LocalServerPort注入端口。
+
+@AutoConfigureMockMvc: 使用Spring的MockMvc，并通过在测试用例上使用@AutoConfigureMockMvc注释，要求为测试用力注入该代码MockMvc代码。
+
+@WebMvcTest : 在测试中，Spring Boot仅实例化了Web层，而不是整个上下文。 在具有多个控制器的应用程序中，甚至可以使用例如@WebMvcTest（HomeController.class）来仅请求实例化一个。
+> 可以加快整个applicaiton的启动速度，因为该注解只指定扫描了部分annotation
+
+@Runwith(SpringRunner.class): 说明了改测试用例要在什么环境下进行测试，在Junit4中需要将@RunWith（SpringRunner.class）添加到测试中，否则注释将被忽略。如果使用的是JUnit 5，则无需添加等效的@ExtendWith（ SpringExtension.class）（如@SpringBootTest）和其他@…Test注释已使用它进行注释。
+   - > @ExtendWith（ SpringExtension.class） 暂时未研究，主要是@Runwith的拓展类提供能力的增强，应用于Junit5中。
+     
+@MockBean:可用于为ApplicationContext中的bean定义Mockito模拟
+
+
+@DirtiesContext：Spring @DirtiesContext从与测试关联的上下文缓存中删除脏的ApplicationContext
