Spring Cloud Spring Data Cloud Spanner对象映射

Spring Data Cloud Spanner允许您通过注释将域POJO映射到Cloud Spanner表：

@Table(name = "traders")
public class Trader {

	@PrimaryKey
	@Column(name = "trader_id")
	String traderId;

	String firstName;

	String lastName;

	@NotMapped
	Double temporaryNumber;
}

Spring Data Cloud Spanner将忽略任何带有@NotMapped注释的属性。这些属性将不会写入或读取Spanner。
