创建定义了名为'entityManagerFactory‘的bean时出错: Java8

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D1Repository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);
}我得到了这个错误：

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);
