Spring Redis无法为数据库类型NONE确定嵌入式数据库驱动程序类

我正在使用上面的数据加载器在我的redis中加载一些数据

然而，我得到了下面的错误

@Component
public class dataloader implements ApplicationRunner {

    private StudentRepositoryImpl s;

    @Autowired
    public dataloader(StudentRepositoryImpl s){
        this.s = s;
    }

    @Override
    public void run(ApplicationArguments applicationArguments) throws Exception {

        System.out.println("hi");

        Student student = new Student("Eng2015001", "John Doe", Student.Gender.MALE, 1);
        s.saveStudent(student);

    }
}

我做错了什么？顺便说一下，我的属性文件是空的。非常感谢您的帮助。

试试这个（每个bean对象都应该是@Autowired的，而不仅仅是使用“new”操作符初始化它）：

配置类：

@配置
@启用缓存
公共类CacheConfig扩展了CachingConfigurerSupport{
@豆子
公共绝地连接工厂绝地连接工厂（）{
JedisConnectionFactory redisConnectionFactory=新的JedisConnectionFactory（）；
//默认值
setHostName（“127.0.0.1”）；
设置端口（6379）；
返回连接工厂；
}
@豆子
公共RedisTemplate RedisTemplate（@Autowired-JedisConnectionFactory cf）{
RedisTemplate RedisTemplate=新RedisTemplate（）；
redisTemplate.setConnectionFactory（cf）；
返回模板；
}
@豆子
public CacheManager CacheManager（@Autowired RedisTemplate RedisTemplate）{
RedisCacheManager cacheManager=新的RedisCacheManager（redisTemplate）；
//过期前的秒数。默认为无限制（0）
cacheManager.setDefaultExpiration（300）；
返回缓存管理器；
}
}

存储库类

@存储库
