Get application context in @SpringUI class

Vaadin 6 / 7 / 8
1

So thats my spring boot:

[code]
@ImportResource(“classpath:spring.xml”)
@SpringBootApplication
public class AppApplication {

public static void main(String[] args) {
    ApplicationContext ctx = SpringApplication.run(AppApplication.class, args);

}

}
[/code]Right now to acces beans I’m using this code:

@SuppressWarnings("serial") @SpringUI public class MyVaadinUI extends UI { ApplicationContext applicationContext = new ClassPathXmlApplicationContext("spring.xml"); Anyway creating another Context object is not good practise. How can I acces “ctx” from AppApplication in UI ?

Inject Application context markin your field with
@Autowired
 annotation (or use constructor injection) or make yout UI class implement ApplicationContextAware interface

@SpringUI
public class MyVaadinUI extends UI {
    @Autowired
    ApplicationContext applicationContext;
}

or

@SpringUI
public class MyVaadinUI extends UI implements ApplicationContextAware {
    ApplicationContext applicationContext;

    public void setApplicationContext(ApplicationContext appCtx) {
        this.applicationContext = appCtx;
   }
}

Sorry that i didn’t mention it. I tried with @Autowired but when I try to take a bean from @Autowired context all I receive is NULL. In class AppApplication all beans are fine. I tried right now method with implement ApplicationContextAware interface, same situation getBean() return NULL.

ApplicationContext @Autowired works well for me, also importing bean definitions from xml file with @ImportResource.

Could you post some more code?
