How to access a variable from another class in Spring

Question

I'm trying to access a variable from another class via autowiring in Spring but I get a null pointer. The only way I can is by having it newly instantiated as static. Is there a way I can access it (the variable) in a non-static context - maybe something like autowiring?

Via static:

@Component
@Scope(proxyMode = ScopedProxyMode.TARGET_CLASS, value = "prototype")
public class ClassWhereVariableIsNeeded {

    public static void setViews(Views aViews) {
        views = aViews;
    }

    private static Views views;
    .
    .
    .

    private void method() {
        views.thisVariable.....
    }

I'd like it somewhat like this:

@Component
@Scope(proxyMode = ScopedProxyMode.TARGET_CLASS, value = "prototype")
public class ClassWhereVariableIsNeeded {

    @Autowired
    Views views;
    .
    .
    .

    private void method() {
        views.thisVariable.....
    }

Where the variable resides:

@Component
@Scope(proxyMode = ScopedProxyMode.TARGET_CLASS, value = "prototype")
public class Views extends ClassWhereVariableIsNeeded {


    ThisVariable thisVariable;
    .
    .
    .

To access any variable and/or method you must set this variable/method access modifier higher than private. private modifier restricts access to within the defining (or inner) class and nowhere else. You can provide public/default/package (access) method for other classes to use/access your private variable
