Hibernate注解对应Oracle主键序列问题错误收集

1,could not get next sequence value

Myeclipse生成的注解问题

@Id
@GeneratedValue(strategy = SEQUENCE, generator = "seq_sql_err")
@SequenceGenerator(name = "seq_sql_err")
@Column(name = "ID", unique = true, nullable = false, precision = 22, scale = 0)

上面是myeclipse生成的

运行时会报上面的错误，测试良久，把@SequenceGenerator(name = "seq_sql_err")改成

@SequenceGenerator(name="seq_sql_err",allocationSize=1,initialValue=1, sequenceName="seq_sql_err")就不用报错了。
