An alternative to @Value annotation in static function

Question

It's not possible to use @Value on a static variable.

@Value("${some.value}")
static private int someValue;

static public void useValue() {
    System.out.println(someValue);
}

When I do this, 0 is printed. So what is a good alternative to this?

Answer 1

Spring inject noting in static field (by default).

So you have two alternatives:

• (the better one) make the field non static
• (the ugly hack) add an none static setter which writes in the static field, and add the @Value annotation to the setter.

---

• and then there is the trick with the MethodInvokingFactoryBean -- this example is for autowired fiels, but I guess you can adapt it for @Value too
