【Spring源码解析】组件注册-@Scope设置组件作用域

前言

接上一篇 Spring源码解析之@ComponentScan自定义TypeFilter指定过滤规则

实现

1. 配置

@Configuration
public class BeanConfig2 {

    // singleton prototype
    @Scope("singleton")
    @Bean
    public Person person() {
        return new Person("config", 18);
    }
}

2. 测试

@Test
public void test02() {
    AnnotationConfigApplicationContext applicationContext = new AnnotationConfigApplicationContext(BeanConfig2.class);
    String[] beanDefinitionNames = applicationContext.getBeanDefinitionNames();
    for (String name: beanDefinitionNames) {
        System.out.println(name);
    }
    Person bean = applicationContext.getBean(Person.class);
    Person bean2 = applicationContext.getBean(Person.class);
    System.out.println(bean2 == bean);
}
