将 h2 更改为 mysql db on spring boot get error

Question

I'm working on spring boot v2.3.5.

My problem is I set my variable “hibernate.dialect” to MySQL5InnoDBDialect.

Then error is returned that MySQL syntax error when creating table.

Syntax error in SQL statement "CREATE TABLE A (ID BIGINT NOT NULL AUTO_INCREMENT, ACCESS_TOKEN VARCHAR(2000) NOT NULL, CREATE_DATE DATETIME NOT NULL, REFRESH_TOKEN VARCHAR(2000) NOT NULL, USER_NO VARCHAR(100) NOT NULL, PRIMARY KEY (ID)) ENGINE=[*]INNODB"; expected "identifier"; SQL statement

But actually when i copied that command, it works. Plus, when I change the option from Innodb to H2 db, it works.

Any ideas with my problems?

If you are switching your datasource between different dababases you have to update configuration properly. From available information you have provided I assume you need to updated it as follows:

spring.jpa.properties.hibernate.dialect = MySQL5InnoDBDialect
spring.datasource.driver-class-name = com.mysql.jdbc.Driver
spring.datasource.url = jdbc:mysql://localhost/yourDbName
spring.datasource.username = dbUsername
spring.datasource.password = dbPassword

please update url, username and password according to your environment
