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

说明：springBoot工程访问，获取界面数据时，报错！！！

数据库存在不能识别的列，也就是访问的表不存在这个字段，

那么针对这个问题，去调节一下entity类

  @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY) //自增设置
    /**
     * @Column 注解（表的字段）  必须加上 ，不然 test 会报错
     *   报错信息 ： 数据库表 不存在 某个字段
     *   com.mysql.jdbc.exceptions.jdbc4.MySQLSyntaxErrorException: Unknown column 'flight0_.arrival_city' in 'field list'
