I am using Spring 3.0 for my project, I am having a class MySingletonClass, it is singleton as below :
//@Component("mySingletonClass")
public class MySingletonClass {
private static MySingletonClass obj = new MySingletonClass();
public static MySingletonClass getSingleObj() {
return obj;
}
}
spring xml bean configuration for this class is as below :
<bean id="mySingletonClass" class="app.MySingletonClass" factory-method="getSingleObj" />
I was trying to remove bean configuration and use annotation. how do I write annotation for factory method?
Thanks in advance !!
Spring creates instances like singleton by default. You can just do.
@Component("mySingletonClass")
public class MySingletonClass {
}
And if you don't change scope your component is singleton.
Spring component's are automatically created as Singletons.
Declare the annotation @Controller on the class
@Controller
public class MySingletonClass {
}
Then in your Spring Config file, declare like:
<bean id="mySingleton" class="com.package.MySingletonClass">
Then to use in another class you can use Autowiring or Setter/Constructor dependency injection.
@Component
public class OtherClass {
@Autowired
private MySingletonClass mySingleton;
}
