7.SpringBoot整合Junit4测试

SpringBoot整合Junit4测试

1.导入Junit4测试坐标

  
        
            org.springframework.boot
            spring-boot-starter-test
            test
        

2.在Test中写一个小Demo测试

//创建容器
@RunWith(SpringRunner.class)
//指定配置文件
@SpringBootTest(classes = MySpringAppliccation.class)
public class Demo {

    @Autowired
    private UserMapper userMapper;

    @Test
    public void fun1(){
        System.out.println(userMapper.findById(1));
    }
