com.mysql.jdbc.exceptions.jdbc4.MySQLSyntaxErrorException: Table 'test.ac_flight' doesn't exist

1....springBoot運行報錯：

  Unknown column 'flight0_.arrival_city' in 'field list'：

說明：springBoot工程訪問，獲取界面數據時，報錯！！！

數據庫存在不能識別的列，也就是訪問的表不存在這個字段，

那么針對這個問題，去調節一下entity類

  @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY) //自增設置
    /**
     * @Column 注解（表的字段）  必須加上 ，不然 test 會報錯
     *   報錯信息 ： 數據庫表 不存在 某個字段
     *   com.mysql.jdbc.exceptions.jdbc4.MySQLSyntaxErrorException: Unknown column 'flight0_.arrival_city' in 'field list'
