MySQL and Hibernate are not configuring-CodePudding

I'm working on a spring boot project example and I have already created the database but when I configure the database, it doesn't seem to work. It doesn't give me an error though but when I execute the application, nothing shows on the console that I have added the hibernate properties. I was expecting something like HHH000204:Processing PersistenceUnitInfo etc. As a result of that, when I tried creating columns in table for the Employee entity it didn't work.

CodePudding user response：

 spring.jpa.show-sql=true

 spring.jpa.properties.hibernate.format_sql=true

 spring.datasource.driver-class-name=com.mysql.jdbc.Driver

Add these lines of code to you application.properties it will print sql queries in formated form and let me know if it works or not

-- change the MySQL dependency in pom.xml In ur MySQL dependency artifactId is MySQL-connector-j it's not fulfilled Add Datasource driver in ur application properties like check the below answer --

    <dependency>
        <groupId>mysql</groupId>
        <artifactId>mysql-connector-java</artifactId>
        <scope>runtime</scope>
    </dependency>
