[FIXED] How to inject a string in a JAVA servlet´s method?

Issue

I am new using dependency injection. Can anyone tell me how to configure a servlet to inject a string URI pointing to a file? The method signature is the following:

@Inject

public void setCar(String value) 
 {
        CarUri =value;
    }

Thanks in advance!

Solution

You can try injecting @Named fields

// inside module
@Provides
@Named("CarURI")
public String carURI() {
  return "URI";
}

@Inject
public void setCar(@Named("CarURI") String value) {
    CarUri = value;
}
