JavaSpring-Bean的Scope思维导图

@Service //1 public class DemoSingletonService { }

@Service @Scope("prototype")//1 public class DemoPrototypeService { }

@Configuration @ComponentScan("com.wisely.highlight_spring4.ch2.scope") public class ScopeConfig { }

public class Main { public static void main(String[] args) { AnnotationConfigApplicationContext context = new AnnotationConfigApplicationContext(ScopeConfig.class); DemoSingletonService s1 = context.getBean(DemoSingletonService.class); DemoSingletonService s2 = context.getBean(DemoSingletonService.class); DemoPrototypeService p1 = context.getBean(DemoPrototypeService.class); DemoPrototypeService p2 = context.getBean(DemoPrototypeService.class); System.out.println("s1与s2是否相等:"+s1.equals(s2)); System.out.println("p1与p2是否相等:"+p1.equals(p2)); context.close(); } } s1与s2是否相：true p1与p2是否相：false
