java – jdbc4.MySQLSyntaxErrorException：数据库中不存在表

我正在使用SpringBoot开发一个Web应用程序,这是我的application.properties文件,用于指定访问数据库的凭据：spring.datasource.driverClassName=com.mysql.jdbc.Driverspring.datasource.url=jdbc:mysql://127.0.0....

我正在使用SpringBoot开发一个Web应用程序,这是我的application.properties文件,用于指定访问数据库的凭据：

spring.datasource.driverClassName=com.mysql.jdbc.Driver
spring.datasource.url=jdbc:mysql://127.0.0.1:3306/Salamander
spring.datasource.username=root
spring.datasource.password=root
spring.jpa.hibernate.ddl-auto=create-drop
spring.jpa.properties.hibernate.dialect=org.hibernate.dialect.MySQLInnoDBDialect

但是当我尝试运行SpringBoot应用程序时,它给了我这个错误：

当然我有一个名为user的实体,但数据库是空的.但

spring.jpa.hibernate.ddl-auto=create-drop

应该说hibernate在db中再次创建表,对吧？所以有什么问题？

如果我使用远程数据库执行相同操作,即使远程数据库为空,也可以正常工作.

解决方法:

这个问题是通过删除修复的
spring.jpa.properties.hibernate.dialect = org.hibernate.dialect.MySQLInnoDBDialec吨
