本文介绍了hibernate.hbm2ddl.auto =创建(不创建表)的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我了解到hibernate.hbm2ddl.auto创建 Schema 并执行其他各种操作.但是就我而言，它不创建架构.
我在本地主机上使用MYSQL.它没有名为休眠的架构.
我尝试了其他各种方法，但仍然收到相同的错误.
i have learned that hibernate.hbm2ddl.auto creates Schema and does various other things.but somehow in my case it does not create schema.
Am using MYSQL at my localhost. it does not have schema named hibernate.
I have tried various other thing but still get the same Error .

推荐答案
(如果有人遇到相同的问题). 使用MYSQL 5或更高版本的服务器. 将您的方言更改为以下内容:
if anyone faces the same issue. using MYSQL 5 or above version server. change your dialect to below:
<property name="hibernate.dialect">org.hibernate.dialect.MySQL55Dialect</property>
SQL方言
org.hibernate.dialect.MySQL5Dialect
org.hibernate.dialect.MySQL55Dialect
org.hibernate.dialect.MySQL57Dialect
