Question

在我的D1模型中：

import javax.persistence.Column;
import javax.persistence.Id;
public class D1 
{
    @Id
    @Column(name = "id_client")
    private BigDecimal id_contrats;

    @Column(name = "name_client")
    private Timestamp dat_deb_dwh;

}

在D1存储库中

import javax.persistence.Entity;
import javax.persistence.Table;
import java.util.Date;
import org.springframework.data.jpa.repository.Query;
import org.springframework.data.repository.CrudRepository;
import org.springframework.data.repository.query.Param;
import io.A1.B1.api.P1.data.model.D1;

@Entity(name = "tmp.c1")
@Table(name = "c1", schema="tmp") 
public interface D1Repository 
{
    @Query(value = "SELECT * FROM #{#entityName} )
    T getId(@Param("id_client") BigDecimal id_client);

}

我收到此错误：

请帮忙，请不要犹豫。

您需要添加@Entity以指定这是一个实体，并添加@Table（name =“ insert_table_name”）以指定它与类顶部的数据库表的关系。

@Entity
@Table(name = "c1", schema="tmp") 
public class D1 
{
    @Id
    @Column(name = "id_client")
    private BigDecimal id;

    @Column(name = "name_client")
    private Timestamp dat_deb_dwh;

}

public interface D1Repository extends CrudRepository<D1, BigDecimal>
{

    D1 findById(BigDecimal id_client);

}

创建名称为'entityManagerFactory'的bean时出错：Java8
