/**
 * redis连接测试

 * @author 段誉
 * @create 2019-04-11 9:27
 */
@RunWith(SpringRunner.class)
@SpringBootTest
public class RediscacheApplicationTest {
  @Autowired
  private StringRedisTemplate stringRedisTemplate;

  @Test
  public void contextLoads() {
    stringRedisTemplate.opsForValue().set("k1", "v1");
    System.out.println(stringRedisTemplate.opsForValue().get("k1"));
  }
}

原因

是因为我在搭建好springboot项目后没有创建Application.java项目启动类导致的

解决办法

创建完Application.java后，再重新运行测试类正常运行
