Spring Ioc Configration - Annotation

1.配置類註解@Configuration.

2.Bean註解 @Bean.

3.導入其餘配置類@Import.

4.回調函數

@Bean(initMethod = "init", destroyMethod = "cleanup" )

5.做用範圍

　　 @Scope("prototype") 

6.例子

public static void main(String[] args) {
   AnnotationConfigApplicationContext ctx = 
   new AnnotationConfigApplicationContext();

   ctx.register(AppConfig.class, OtherConfig.class);
   ctx.register(AdditionalConfig.class);
   ctx.refresh();

   MyService myService = ctx.getBean(MyService.class);
   myService.doStuff();
}

或者經過註解引入

 @ContextConfiguration(classes = {PersistenceConfig.class, CoreConfig.class})
