Answer 1

Upgrade MySql driver to mysql-connector-java - 8.0.17 and

Those who are using greater than MySQL 5.5 version

change their driver property

from com.mysql.jdbc.Driver to com.mysql.cj.jdbc.Driver

because:

Loading class com.mysql.jdbc.Driver. This is deprecated. The new driver class is com.mysql.cj.jdbc.Driver. The driver is automatically registered via the SPI and manual loading of the driver class is generally unnecessary.INFO - HHH000401: using driver [com.mysql.jdbc.Driver] at URL....

in hibernate.properties

hibernate.connection.driver_class = com.mysql.cj.jdbc.Driver

or if you are using hibernate.cfg.xml update

<property name="connection.driver_class">com.mysql.cj.jdbc.Driver</property>

Answer 2

Use HSQLDialect not MYSQLDialect

spring.jpa.database-platform=org.hibernate.dialect.HSQLDialect
spring.jpa.hibernate.ddl-auto=none
spring.jpa.show-sql=true


spring.datasource.url=jdbc:mysql://localhost:3306/xyz?serverTimezone=CST6CDT
spring.datasource.username=root
spring.datasource.password=root
spring.datasource.driverClassName=com.mysql.cj.jdbc.Driver

Answer 3

connection.driver_class property must be compatible with mysql-connector jar.

mysql-connector < 5.5.xx use com.mysql.jdbc.Driver

mysql-connector > 5.5.xx use com.mysql.cj.jdbc.Driver

Answer 4

I had the same issue when I deployed my war file to tomcat in my demo environment. My application was not getting started because, in my /tomcat/webapp/ROOT folder, I found my war file Myapp.war there. i.e. In my ROOT folder, it has WEB-INF, META-INF, and Myapp.war, which caused the startup issue. I deleted the war file and it worked.

Answer 5

 <property name="connection.url">jdbc:mysql://localhost:3306/test?serverTimezone=UTC</property>

You need to set serverTimezone.

Answer 6

You need to add mysql JDBC jar in your dependencies.

---

1. Fix your driver class name as com.mysql.jdbc.Driver.

2. Fix your username and password property as

   "connection.username" for database user
   "connection.password" for database user password
   

3. Create mysql database. See this.

4. For SSL warning, modify your connection.url to include use ssl false. For example, jdbc:mysql://localhost:3306/<enter-your-database>?autoReconnect=true&useSSL=false

5. Modify your mysql dialect to org.hibernate.dialect.MySQLDialect

6. Use <property name="hbmdl.auto">create-drop</property> instead of <property name="hbmdl.auto">update</property> however do not use this option in production. You should create schema yourself and not do it via hibernate.
