Bean not getting provided from ConfigurationProperties with prefix

I enhanced Application class as a Configuration class and also marked it a @Component so that the provided values can be Autowired in the using code:

@Configuration
@EnableScheduling
@Component
public class BinancebotApplication implements CommandLineRunner {

    @Bean
    @Primary
    @ConfigurationProperties(prefix="chartpatternsignal.datasource")
    public DataSource primaryDataSource() {
        return DataSourceBuilder.create().build();
    }

I tried autowire the above DataSource:

@Configuration
public class ChartPatternSignalDaoImpl {
  @Qualifier("chartpatternsignal")
  @Autowired
  DataSource dataSource;

In my pom.xml I have used the spring-boot-starter-data-jpa.

But it is not working:

Caused by: org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type 'javax.sql.DataSource' available: expected at least 1 bean which qualifies as autowire candidate.

You are calling @Qualifier("chartpatternsignal") , however your Datasource is not named that.

It would be @Qualifier("primaryDataSource")

Try:

@Component
public class ChartPatternSignalDaoImpl {

  @Qualifier("primaryDataSource")
  @Autowired
  DataSource dataSource;

or:

@Configuration
public class BinancebotConfiguration  {

    @Bean
    @Primary
    @Qualifier("myLovelyDataSource")
    @ConfigurationProperties(prefix="chartpatternsignal.datasource")
    public DataSource primaryDataSource() {
        return DataSourceBuilder.create().build();
    }

}

Then autowrite it by qualifier:

  @Qualifier("myLovelyDataSource")
  @Autowired
  DataSource dataSource;

The Springboot Documentation showcases how to create a DataSource using @ConfigurationProperties annotation:

https://docs.spring.io/spring-boot/docs/current/reference/html/howto.html#howto.data-access

Application class

@SpringBootApplication
@EnableScheduling
public class BinancebotApplication implements CommandLineRunner {


}

Configuration Class

@Configuration
public class MyDataSourceConfiguration {

    @Bean
    @ConfigurationProperties("app.datasource")
    public DataSource dataSource() {
        return DataSourceBuilder.create().build();
    }

}

Service Class

@Service
public class BinanceService {

   @Autowired
   DataSource dataSource;

}

application.properties

app.datasource.url=jdbc:h2:mem:mydb
app.datasource.username=sa
app.datasource.pool-size=30
