Spring Boot自动装配存储库始终为空[重复]

使用Spring Boot的自动装配功能可以极大地简化项目的开发过程。然而，有时候在使用自动装配的过程中，可能会遇到某些存储库始终为空的问题。本文将介绍这个常见的问题，并提供解决方案。

spring.datasource.url=jdbc:mysql://localhost:3306/mydatabase
spring.datasource.username=root
spring.datasource.password=123456
spring.datasource.driver-class-name=com.mysql.jdbc.Driver

@Entity
@Table(name = "user")
public class User {
    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    private Long id;
    private String name;
    // getters and setters
}

@SpringBootApplication
@EnableJpaRepositories(basePackages = "com.example.repository")
public class Application {
    public static void main(String[] args) {
        SpringApplication.run(Application.class, args);
    }
}

@Entity
@Table(name = "user")
public class User {
    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    private Long id;
    private String name;
    // getters and setters
}

@Repository
public interface UserRepository extends JpaRepository {
    // 自定义查询方法
}

@SpringBootApplication
@EnableJpaRepositories(basePackages = "com.example.repository")
public class Application {
    public static void main(String[] args) {
        SpringApplication.run(Application.class, args);
    }
}

@Service
public class UserService {
    @Autowired
    private UserRepository userRepository;
    public List getAllUsers() {
        return userRepository.findAll();
    }
    // 其他业务方法
}
