You can go for Hikari Connection Pool.Return Hikari DataSource object.Sample code as below :
import com.zaxxer.hikari.HikariConfig;
import com.zaxxer.hikari.HikariDataSource;
#Bean
public DataSource dataSource() {
// In classpath from spring-boot-starter-web
final Properties props = new Properties();
props.put("driverClassName", "com.mysql.jdbc.Driver");
props.put("jdbcUrl", "jdbc:mysql://localhost:3306/master?createDatabaseIfNotExist=false");
props.put("username", "root");
props.put("password", "mysql");
HikariConfig hc = new HikariConfig(props);
HikariDataSource ds = new HikariDataSource(hc);
return ds;
}
