Spring-整合JUnit

1、新导入坐标（之前整合Mybatis的坐标都要）

            junit
            junit
            4.12
            test
        
        
            org.springframework
            spring-test
            5.2.10.RELEASE
        

2、创建测试类

3、设置类运行器

@RunWith(SpringJUnit4ClassRunner.class)

4、告诉测试类Spring的环境

@ContextConfiguration(classes = SpringConfig.class)

5、通过自动装配引入业务层接口

@Autowired

private UserService userService；

6、写测试方法，需要加注解@Test

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(classes = SpringConfig.class)
public class UserServiceTest {
    @Autowired
    private UserService userService;

    @Test
    public void  testFindById(){
        System.out.println(userService.findById(1));
    }
}

结果：
