Spring Configuration Init Method

Question

How can I tell Spring to run that init method? I need to get the Proxied Async class and do some initialization with it.

@Configuration
@EnableAsync
public class Config  {

 @Bean
 public AsyncBean asyncProxyBean(){
    return new AsyncBean();
 }

 public void init(){
   doStuffWithProxy(asyncProxyBean());
 }

 @Bean
 public String thisIsHack(){ //this runs the init code but bean is a bit hacky
    doStuffWithProxy(asyncProxyBean());
    return "";
 }

}

Answer 1

你可以使用@PostConstruct来做到这一点

Answer 2

Use the @PostConstruct annotation along with:

• <context:annotation-config /> or
• <bean class="org.springframework.context.annotation.CommonAnnotationBeanPostProcessor" />

See here for details. This is a Java EE annotation, so may not be appropriate in your environment.

Answer 3

• usually you can do the things to the original object. You rarely need to do things with the proxy - that way you rely on some spring internals (the way it works with dynamic proxies)
• if you really need the proxy, then I guess you can try using a BeanPostProcessor
