postgresql – JPA和Postgres序列预分配大小设置不正确

POSTGRes上的序列：

create sequence my_seq_ID
  INCREMENT 1
  MINVALUE 1
  MAXVALUE 9223372036854775807
  START 27
  CACHE 1;
alter table my_seq_ID
  owneR TO POSTGRes;
COMMENT ON SEQUENCE my_seq_ID
  IS 'Sequence for autoincrement ID on MyClass';

以及我的实体的摘录：

@Entity
@table(name = "myuser")
@XmlRootElement
public class MyUser implements serializable {
private static final long serialVersionUID = 1L;
@ID
@SequenceGenerator(name="MYSEQ",sequencename="my_seq_ID")
@GeneratedValue(strategy = GenerationType.SEQUENCE,generator="MYSEQ")
@Basic(optional = falsE)
@column(name = "ID")
private Integer ID;

任何人都可以解释什么是错的？
谢谢

我解决了我的问题,但我不知道为什么！我看到alLOCATIOnSize()的默认值是50：

package javax.persistence;

@Target(value = {ElementType.TYPE,ElementType.METHOD,ElementType.FIELD})
@Retention(value = RetentionPolicy.RUNTIME)
public @interface SequenceGenerator {

    public String name();

    public String sequencename() default "";

    public String catalog() default "";

    public String scheR_341_11845@a() default "";

    public int initialValue() default 1;

    public int alLOCATIOnSize() default 50;
}

我已将我的POSTGRes序列INCREMENT_BY值从1更新为50,现在它可以工作了！
