spring - create an instance of DataSource and use inside constructor -

in current spring-boot project, have class:

@component public class oauthtokenstore extends jdbctokenstore {   public oauthtokenstore() {     super(...);   } } 

the atribute super(...) should valid datasource. have configuration in application.properties:

# jdbc.x spring.datasource.driverclassname=com.mysql.jdbc.driver spring.datasource.url=jdbc:mysql://localhost/lojacms spring.datasource.username=root spring.datasource.password=  # hibernate.x spring.jpa.database-platform=org.hibernate.dialect.mysql5dialect spring.jpa.dialect=org.hibernate.dialect.mysql5dialect spring.jpa.show-sql=false spring.jpa.hibernate.ddl-auto=validate 

is there way create instance of datasource , use in constructor?

you need inject datasource bean can pass oauthtokenstore constructor using @inject.

@component public class oauthtokenstore extends jdbctokenstore {    @inject   public oauthtokenstore(datasource ds) {     super(ds);   } } 

if don't yet have bean of type datasource defined in application you'll need one:

@configuration public class config {      @bean     public drivermanagerdatasource datasource() {         drivermanagerdatasource datasource = new drivermanagerdatasource();          datasource.setdriverclassname("com.mysql.jdbc.driver");         datasource.seturl("jdbc:mysql://localhost/lojacms");         datasource.setusername("root");         datasource.setpassword("");          return datasource;     } }
