java為什么要實現(xiàn)序列化 oracle數(shù)據(jù)庫中ID怎么自增長,怎么設置啊?

oracle數(shù)據(jù)庫中ID怎么自增長,怎么設置???
Oracle static int maxvaluefive=9999999
private static int minvaluefive=0
private static AtomicInteger atomic=new AtomicInteger(minvaluefive)
/**創(chuàng)建序列SEQu TBu DataApproval
private static int maxvaluefive=999999

靜態(tài)字符串getSeqFive(int coverPad){用于(){
int電流=原子。獲?。ǎ?/p>
int newValue=current>=maxvaluefive?minvaluefive:當前1
如果(原子比較數(shù)據(jù)集(current,newValue)){
返回StringUtils.leftPad文件(String.valueOf值(當前),coverPad,“0”)
}
}
