I have @Autowired
service which has to be used from within a static method. I know this is wrong but I cannot change the current design as it would require a lot of work, so I need some simple hack for that. I can't change randomMethod()
to be non-static and I need to use this autowired bean. Any clues how to do that?
@Service
public class Foo {
public int doStuff() {
return 1;
}
}
public class Boo {
@Autowired
Foo foo;
public static void randomMethod() {
foo.doStuff();
}
}
You can do this by following one of the solutions:
This approach will construct the bean requiring some beans as constructor parameters. Within the constructor code you set the static field with the value got as parameter for constructor execution. Sample:
@Component
public class Boo {
private static Foo foo;
@Autowired
public Boo(Foo foo) {
Boo.foo = foo;
}
public static void randomMethod() {
foo.doStuff();
}
}
The idea here is to hand over a bean to a static field after bean is configured by spring.
@Component
public class Boo {
private static Foo foo;
@Autowired
private Foo tFoo;
@PostConstruct
public void init() {
Boo.foo = tFoo;
}
public static void randomMethod() {
foo.doStuff();
}
}
