ERROR SqlExceptionHelper ORA-00001: 違反唯一約束條件 (TEST1.SYS_C0011549)

異常問題：
客戶端只能插入一條數據，當插入第二條數據時出現異常 ERROR SqlExceptionHelper ORA-00001: 違反唯一約束條件 (TEST1.SYS_C0011549)
原因：在實體類中沒有配置Oracle的id主鍵導致Oracle主鍵的沖突
解決方案：在實體類中添加注解的序列
//@GeneratedValue中generator里面的值對應@SequenceGenerator中name里面的值（可以隨便定義但一定要相同），
//sequenceName是創建的sequence名字（對應數據庫中創建的序列名），allocationSize表示序列自增長的大小為1
@GeneratedValue(strategy = GenerationType.SEQUENCE, generator="seq")
@SequenceGenerator(name="seq", sequenceName="SEQ_WEATHER",allocationSize = 1)
