你这个类有问题，Spring 没法注入，和依赖没关系

mapper接口是否被扫描，增加@Mapper注解
然后看一下数据源配置：
spring:
datasource:
type: com.alibaba.druid.pool.DruidDataSource
druid:
driver-class-name: com.mysql.cj.jdbc.Driver
url: jdbc:mysql://127.0.0.1:3306/xxx
username: root
password: 123456

//xxx为你的启动类
@SpringBootTest(classes = xxx.class)
@RunWith(SpringRunner.class)
