Multiple DataSource and JdbcTemplate in Spring Boot (> 1.1.0)

Question

I would like to inject a specific JdbcTemplatein a Spring Boot project. I tried to follow this example for multiple DataSourceconfiguration : http://spring.io/blog/2014/05/27/spring-boot-1-1-0-m2-available-now

My code does compile and run, but only the DataSource with the @Primaryannotation is taken into account, no matter what I put as @Qualifier in the SqlServiceclass. My relevant code is the following :

DatabaseConfig.java:

@Configuration
public class DatabaseConfig {

    @Bean(name = "dsSlave")
    @ConfigurationProperties(prefix="spring.mysql_slave")
    public DataSource slaveDataSource() {
        return DataSourceBuilder.create().build();
    }

    @Bean(name = "dsMaster")
    @Primary
    @ConfigurationProperties(prefix="spring.mysql_master")
    public DataSource masterDataSource() {
        return DataSourceBuilder.create().build();
    }

    @Bean(name = "jdbcSlave")
    @Autowired
    @Qualifier("dsSlave")
    public JdbcTemplate slaveJdbcTemplate(DataSource dsSlave) {
        return new JdbcTemplate(dsSlave);
    }

    @Bean(name = "jdbcMaster")
    @Autowired
    @Qualifier("dsMaster")
    public JdbcTemplate masterJdbcTemplate(DataSource dsMaster) {
        return new JdbcTemplate(dsMaster);
    }

}

And I did a quick service to try it out :

SqlService.java:

@Component
public class SqlService {

    @Autowired
    @Qualifier("jdbcSlave")
    private JdbcTemplate jdbcTemplate;

    public String getHelloMessage() {
        String host = jdbcTemplate.queryForObject("select @@hostname;", String.class);
        System.out.println(host);
        return "Hello";
    }

}

It should looks like this:

@Bean(name = "jdbcSlave")
@Autowired
public JdbcTemplate slaveJdbcTemplate(@Qualifier("dsSlave") DataSource dsSlave) {
    return new JdbcTemplate(dsSlave);
}
