我有我的Springboot应用程序的以下代码结构:

我NoSuchBeanDefinitionException对bean的例外UserDao.

异常跟踪:

Caused by: org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type [com.matlb.dao.UserDao] found for dependency: expected at least 1 bean which qualifies as autowire candidate for this dependency.

UserDao.java接口的源代码是

package com.matlb.dao;

import com.matlb.domain.User;
import org.springframework.data.repository.CrudRepository;
import org.springframework.stereotype.Repository;

@Repository
public interface UserDao extends CrudRepository<User,Integer>{

    User findByEmail(String email);
}

我在这里自动装配它

package com.matlb.service;

import com.matlb.dao.UserDao; …

嘿，我想要一个关于在 AWS ECS 容器中使用 MySQL 数据库的设计答案。我没有像目前做一些 MVP 那样使用 RDS。是否可以将 Mysql DB 用作 docker 容器，如果是这样，那么我如何确保在部署此 DB 容器时保留生产数据。

请指导我了解这种情况。
