I need to add a MySQL database in my springboot application(using Maven)
However when I run the project in Eclipse I get:
***************************
APPLICATION FAILED TO START
***************************
Description:
Failed to configure a DataSource: 'url' attribute is not specified and no embedded datasource could be configured.
Reason: Failed to determine a suitable driver class
I already checked all these:
- The database, specified in the application.properties, exists
- Credentials/ url in the application.properties are correct
- Mysql server is running
- The dependency
mysql-connector-j
is included in the pom.xml mysql-connector-j-8.031.jar
is included in the Maven Dependencies
I am using:
- java version "17.0.6" 2023-01-17 LTS
- Apache Maven 3.6.3
- Eclipse Version: 2022-12 (4.26.0)

MyProjectApplication.java
package com.springboot;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
@SpringBootApplication()
public class MyProjectApplication {
public static void main(String[] args) {
SpringApplication.run(MyProjectApplication.class, "--debug");
}
}
I also follow the default spring structure.
