Java 创建表时出现休眠异常

请帮助我找出此异常的原因以及如何解决它

在youtube教程之后，我尝试在名为“abc”的MySQL数据库中创建一个名为“alien”的表。我正在为此使用Hibernate ORM工具和Maven，但是Hibernate抛出了一个异常

org.hibernate.tool.schema.spi.CommandAcceptanceException: Error executing DDL "create table Alien (stud_id integer not null, age integer not null, marks integer not null, stud_name varchar(255), primary key (stud_id)) type=MyISAM" via JDBC Statement

在persistence.cfg.xml文件中，您应该将方言更改为：

org.hibernate.dialent.mysql5innodbdialent

或者您可以简单地删除它，Hibernate应该能够自动检测到它

---

这应该允许Hibernate创建InnoDB表，而不是MyISAM。尝试使用不同的方言，如果您使用的是MySQL v8，那么请使用这些方言

org.Hibernate.dialoge.mysql8dialogue

或

com.MySQL.cj.jdbc.Driver

错误与方言有关，您可以检查其生成

type=MyISAM

而不是

ENGINE=MyISAM

MySQL版本5不推荐使用

type

，

ENGINE

替换该版本，因为您使用的是MySQL8依赖项，所以需要使用

ENGINE

所以查询应该是这样的

create table Alien（列名）Engine=MyISAM

使用

InnoDB

引擎而不是

MyISAM

尝试在控制台或工作台中执行查询
