I have this exception when i try to start my spring boot application. I have added mysql-connector-java and spring-boot-starter-jdbc dependencies and have no idea what do not work.
Description:
Cannot determine embedded database driver class for database type NONE
Action:
If you want an embedded database please put a supported one on the classpath. If you have database settings to be loaded from a particular profile you may need to active it (no profiles are currently active).
EDIT 1 This is my maven config file.

EDIT 2 This here is data source config
public class DataSourceConfig {
@Bean
public DataSource getDataSource() {
BasicDataSource dataSource = new BasicDataSource();
dataSource.setDriverClassName("com.mysql.jdbc.Driver");
dataSource.setUrl("jdbc:mysql://localhost:3306/hcharts");
dataSource.setUsername("root");
dataSource.setPassword("root");
return dataSource;
}
@Bean
public JdbcTemplate jdbcTemplate() {
return new JdbcTemplate(getDataSource());
}
}
It looks like you are missing the @Configuration
annotation on your DatasourceConfig.java
file.
I tried with the annotation and mvn spring-boot:run
starts up fine. Without the annotation I get the text you had indicated followed by a huge stacktrace:
APPLICATION FAILED TO START > [26/818]
Description:
Cannot determine embedded database driver class for database type NONE
Action:
If you want an embedded database please put a supported one on the classpath. If you have database settings to be loaded from a particular profile you may ne$ d to active it (no profiles are currently active).
Here is my my/DatasourceConfig.java
:
package my.config;
import org.apache.commons.dbcp.BasicDataSource;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.jdbc.core.JdbcTemplate;
import javax.sql.DataSource;
@Configuration
public class DatasourceConfig {
@Bean
public DataSource getDataSource() {
BasicDataSource dataSource = new BasicDataSource();
dataSource.setDriverClassName("com.mysql.jdbc.Driver");
dataSource.setUrl("jdbc:mysql://localhost:3306/hcharts");
dataSource.setUsername("root");
dataSource.setPassword("root");
return dataSource;
}
@Bean
public JdbcTemplate jdbcTemplate() {
return new JdbcTemplate(getDataSource());
}
}
The application will also start up, without the @Configuration
, if you add a dependency to a known embedded database like hsqldb
:
<dependencies>
<dependency>
<groupId>org.hsqldb</groupId>
<artifactId>hsqldb</artifactId>
<scope>runtime</scope>
</dependency>
...
</dependencies>
