About injecting @Qualified Strings (or other native values)

amy

Hi,

Let's say I have a service Pojo to which I want to inject a String. Let's say the string is kind of a flag used overall the system.

I'd like to have something like this in my service:Code:
class MyServiceImpl implements MyService {
@Autowired @Qualifier(quot;databaseCatalogquot;) public void setDatabaseCatalog(String databaseCatalog) {   this.databaseCatalog = databaseCatalog; } ...
}
I have a Guice background, and I'm quite new to Spring annotations so I wonder whether  this makes sense in Spring. How should my xml file look like to specify the candidate value of the string?

Thanks in advance for your comments,

You can use @Value annotation for that - 7.4.2 Annotation-based configuration

As Dennis mentioned, you can use @Value in Spring 3.0; however, it's still possible to achieve autowiring of Strings in Spring 2.5.x using @Autowired and @Qualifier as you've shown above. The XML for your example would then simply be the following:Code:
lt;bean id=quot;databaseCatalogquot; class=quot;java.lang.Stringquot;gt;
lt;constructor-arg value=quot;XXXquot; /gt;
lt;/beangt;
Note that the bean's ID matches the qualifier string.

Replace quot;XXXquot; with an appropriate value.

Cool. Thanks for your answers! (I'm using 2.5)
