前台報的錯誤信息：
org.springframework.dao.DataIntegrityViolationException: Could not execute JDBC batch update; SQL [insert into "GOODS" ("GOODSNAME", "BILLSTATUS", "GOODSDISTRICT", "GOODSPRICE", "GOODSCOUNT", "CREATIONTIME", "ID") values (?, ?, ?, ?, ?, ?, ?)]; nested exception is org.hibernate.exception.DataException: Could not execute JDBC batch update
報錯原因：數據庫里的GOODSPRICE字段為number（4，2），整數位只能有兩位，添加的時候，輸入了錯誤的數字。
