POJO类：

		
@Data
public class Point {
    private String x;
    private String y;
}		
		
		

record 实现方式

		
public record Point(String x, String y) {
}		
		
		

		
@ConfigurationProperties(prefix = "user")
public record UserProperties(String firstName, String lastName) {
}

        @Id
        @GeneratedValue(strategy = GenerationType.IDENTITY)
        @Column(name = "id", unique = true, nullable = false, insertable = true, updatable = false)
        Long id,
        String name
