como configurar DataSource dentro da classe configuração para Postgresql

Boa tarde, estou seguindo o curso spring boot: agilidade no desenvolvimento java com spring.

e configurei meu Datasource assim

    @Bean
    public DataSource dataSource() {
        DriverManagerDataSource dataSource = new DriverManagerDataSource();
        dataSource.setDriverClassName("org.postgresql.Driver");
        dataSource.setUrl("jdbc:postgresql://localhost:5432/pactosportclub");
        dataSource.setUsername("postgres");
        dataSource.setPassword("pactodb");
        return dataSource;
    }
