Is it possible to pass a variable to the @Qualifier annotation in Spring?

For example,

```
@Autowried
@Qualifier("datasource_" + "#{jobParameters['datasource.number']}")
private DataSource ds;

```

I have 10 different databases where my Spring batch job runs everyday. The database number is passed as a job parameter. I want to define the datasource to connect to based on the job parameter.

Thanks!
