Data source inject to Crud Repository spring boot

问题

Is there any way to inject or set up data source to Crud Repository? I need one repository and multiple database with same schema. I tried to make hash map with database name and data source and use something like that https://spring.io/blog/2007/01/23/dynamic-datasource-routing/ but it doesn't work

This solved my problem

@Component
public class RoutingDataSource extends AbstractRoutingDataSource {

    @Autowired
    private DatabaseMap databaseMap;

    @Override
    public void afterPropertiesSet() {
        setTargetDataSources(databaseMap.getSourcesMap());
        setDefaultTargetDataSource(databaseMap.getSourcesMap().get("DEFAULT"));
        super.afterPropertiesSet();
    }

    @Override
    protected Object determineCurrentLookupKey() {
        return DatabaseContextHolder.getDatabaseType();
    }

}

@Configuration
public class DatabaseLoader {
    @Bean
    public DatabaseMap databaseMap() {
    //init databases using DataSourceBuilder
    return databaseMap;
    }
}

I change context same way as here https://spring.io/blog/2007/01/23/dynamic-datasource-routing/
