我是冬眠的新手。我正在尝试使用实体类在 mysql 数据库上创建关系表。我想执行@OneToMany关系，但我收到错误。 在这里，我有两个几乎相同的实体类，但是一个实体类"事务.java"可以在数据库上创建表，但"Meal.java"没有创建任何表。 这个类几乎是一样的，但为什么"餐"类不创建任何表？
谢谢

由：
com.mysql.jdbc.exceptions.jdbc4.MySQLSyntaxErrorException： 您的 SQL 语法有误;检查手册 对应于您的MariaDB服务器版本，以便使用正确的语法 接近"本地时间时间"，account_accountNumber整数，主键 (m_Id((引擎=InnoDB' 在第 1 行
在MySQL和MariaDB中，localtime是一个保留字。使用不同的列名称，如local_time：
@Column(name = "local_time")
private LocalTime localTime;
问题是，您使用的是java.time.LocalDate和java.time.LocalTime而不是标准的java.sql.Date或java.util.Date，因此转换存在问题！
您可以使用JodaTime或以正确的方式使用Java8日期和时间API，以与您的数据库/表结构保持一致。
您可以查看此网站以获取更广泛的示例，并选择适合您的 API！
希望这有帮助！
