SpringBoot使用Junit单元测试报错

使用SpringBoot的Junit单元测试，需要引入依赖

<dependency>
          <groupId>org.springframework.boot</groupId>
          <artifactId>spring-boot-starter-test</artifactId>
          <scope>test</scope>
        </dependency>

测试类如下：

@RunWith(SpringRunner.class)
    @SpringBootTest
    @Slf4j
    public class UserControllerTest {
        @Autowired
        private UserService userService;
    
        @Test
        public void testGetUserInfoById() {
            User user = userService.getUserInfoById(1);
            log.info("用户信息:" + user);
        }
    }

运行测试类就报错

仔细看错误提示的错误原因，发现需要在配置SpringBootTest注解的时候，需要配置启动类；

java.lang.IllegalStateException: Unable to find a @SpringBootConfiguration, you need to use @ContextConfiguration or @SpringBootTest(classes=...) with your test

修改如下：添加启动类到calsses中。DemoApplication.java是我的项目启动类文件

@SpringBootTest(classes = {DemoApplication.class})

再次启动，即可正常进行单元测试
