Applying same annotation on multiple fields

Question

Is it possible to apply same annotation on multiple fields (if there are many private fields and it just looks awkward to annotate them all.

So What I have is like

@Autowired private BlahService1 blahService1;
@Autowired private BlahService2 blahService2;
@Autowired private BlahService3 blahService3;

and so on

I tried the following but it won't work

@Autowired{     
   private BlahService1 blahService1;       
   private BalhService2 blahService2;   
}

Some thing fancy with custom annotations perhaps?

Answer 1

No, but you could annotate your constructor rather than your fields. This would have the additional benefit to make your class more easily testable, by injecting mock dependencies when constructing the instance to test (which is the main reason why dependency injection is useful) :

@Autowired
public MyClass(BlahService1 blahService1, BlahService2 blahService2, BlahService3 blahService3) {
    this.blahService1 = blahService1;
    this.blahService2 = blahService2;
    this.blahService3 = blahService3;
}
