Spring ApplicationContext接口功能详细介绍

   //处理国际化资源(国际化能力)
       //中文(参数：key，变化的信息,翻译的类型)
        //根据key找到不同语言的翻译结果
        System.out.println(context.getMessage("hi", null, Locale.CHINA));
      //英文
        System.out.println(context.getMessage("hi", null, Locale.ENGLISH));
        //日文
        System.out.println(context.getMessage("hi", null, Locale.JAPANESE));

//根据磁盘的路径获取单个资源
context.getResources("classpath:spring.properties");
//获取多个资源
  Resource[] resources = context.getResources("classpath*:META-INF/spring.factories");
        for (Resource resource : resources) {
            System.out.println(resource);
        }

       System.out.println(context.getEnvironment().getProperty("java_home"));
        System.out.println(context.getEnvironment().getProperty("server.port"));

//用户已注册事件
public class UserRegisteredEvent extends ApplicationEvent {
   // source 事件的事件源  
  public UserRegisteredEvent(Object source) {
        super(source);
    }
}

context.publishEvent(new UserRegisteredEvent(context));

@Component
public class Component2 {
    private static final Logger log = LoggerFactory.getLogger(Component2.class);
    @EventListener
//发的是什么事件，就用什么事件来接收
    public void aaa(UserRegisteredEvent event) {
        log.debug("{}", event);
        log.debug("发送短信");
    }
}

@Component
public class Component1 {
    private static final Logger log = LoggerFactory.getLogger(Component1.class);
    @Autowired
    private ApplicationEventPublisher context;
    public void register() {
        log.debug("用户注册");
        context.publishEvent(new UserRegisteredEvent(this));

context.getBean(Component1.class).register();
