Question

我有maven项目。 pom.xml中：

</project>

另外，我有一个实体地址。

package root.entity;
import javax.persistence.*;
@Entity
@Table(name = "Address")
public class Address {
...
}

我有这个entiry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> {
...
}

服务界面与实施。

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{
...
}

我的application.properties文件：

#DB properties:
db.driver=com.mysql.jdbc.Driver
db.url=jdbc:mysql://localhost:3306/labsdb?useSSL=false
db.username=root
db.password=rootPassword
 
#Hibernate Configuration:
db.hibernate.dialect=org.hibernate.dialect.MySQLDialect
db.hibernate.show_sql=true
db.entitymanager.packages.to.scan=root.entity
db.hibernate.hbm2ddl.auto = create

spring.datasource.driverClassName=com.mysql.jdbc.Driver
spring.datasource.url=jdbc:mysql://localhost:3306/labsdb
spring.datasource.username=root
spring.datasource.password=rootPassword

security.require-ssl=false

我的开始档案：

package root;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
@SpringBootApplication
public class TestApp {
    public static void main(String[] args) {
        SpringApplication.run(TestApp.class, args);
    }
}

但是，运行应用程序后我有错误：

请帮帮我。我有简单的应用程序具有相同的结构和逻辑，但它工作正常。所以，我不知道如何修复问题。

Answer 1

将@NoRepositoryBean添加到您的CrudRepository中。这样一来，仍然可以进行自动配置，而不必手动设置组件扫描基本软件包。

接口org.springframework.data.repository.Repository是实际spring数据存储库的标记。由于您的CrudRepository扩展了Repository，因此spring试图为crudRepository初始化一个名为T的Spring托管存储库（该存储库实际上会转换为Object）。由于Object不是由Hibernate管理的，因此启动时验证失败并崩溃。

@NoRepositoryBean将告诉Spring不要为实现Repository的特定类生成备用存储库。

Answer 2

我猜你错过了

@Autowired 
Private AddressRepository addressRepository;

在您的服务方式中。

Answer 3

问题是没有AddressRepository的实现。

我建议在实际实现而不是接口上使用@Repository和@Service等构造型。

编辑我现在看到你正在使用spring数据来提供AddressRepository接口的实现。也许某些东西没有在那里正确连线？您发布的异常表示无法初始化AddressRepository。以前没有使用过弹簧数据，我不知道为什么会这样。

创建名为＆＃34; * repository＆＃34;
