Also, I have an entity Address.
另外，我有一个实体地址。
package root.entity;
import javax.persistence.*;
@Entity
@Table(name = "Address")
public class Address {
...
}
I have repository for this entiry.
我有这个条目的存储库。
package root.repository;
import org.springframework.data.jpa.repository.JpaRepository;
import org.springframework.stereotype.Repository;
import root.entity.Address;
@Repository
public interface AddressRepository extends JpaRepository<Address, Integer> {
...
}
And service interface with implementation.
和服务接口与实现。
package root.service.interfaces;
import root.entity.Address;
public interface AddressServiceInterface {
...
}
package root.service;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import root.entity.Address;
import root.repository.AddressRepository;
import root.service.interfaces.AddressServiceInterface;
@Service
public class AddressService implements AddressServiceInterface{
...
}

Please, help me. I have simpe app with the same structure and logic, but it work's fine. So, I don't know how to repair issue.
请帮我。我有一个具有相同结构和逻辑的 simpe 应用程序，但它工作正常。所以，我不知道如何修复问题。
回答by Abhishek Ekaanth
I guess you have missed to
我猜你错过了
@Autowired
Private AddressRepository addressRepository;
in your service method.
在您的服务方法中。
回答by Daniel
The problem is that there is no implementation of AddressRepository.
问题是没有实现 AddressRepository。
I would recommend using stereotypes such as @Repository and @Service on the actual implementation rather than the interface.
我建议在实际实现而不是接口上使用诸如 @Repository 和 @Service 之类的构造型。
edit I now see that you're using spring data to provide the implementation of the AddressRepository interface. Maybe something is not wired up correctly there? The exception you posted indicates that AddressRepository could not be initialized. Having not used spring data before, I'm not sure why this is.
编辑我现在看到您正在使用 spring 数据来提供 AddressRepository 接口的实现。也许那里没有正确连接？您发布的异常表明无法初始化 AddressRepository。之前没有使用过 spring 数据，我不确定这是为什么。
