##说明  
  spring boot 事件监听，解耦业务，通过ApplicationEventPublisher 发布事件  
通过`ApplicationEventPublisher`发布事件，在Controller里使用`@EventListener`监听事件，如果想实现异步解耦业务，  
需要全局启用异步任务注解`@EnableAsync`,然后在事件监听里面加上`@Async`，也可以通过`@Order()`对不同的业务实现按顺序

###测试用例代码
```java
@Slf4j
@Component
public class ApplicationReadyEventListener implements ApplicationListener<ApplicationReadyEvent> {
    @Autowired
    PlayerOnLoginService playerOnLoginService;
    @Override
    public void onApplicationEvent(ApplicationReadyEvent event) {
        log.info("......ApplicationReadyEvent......");
        log.info("开始测试");
        RequestVO requestVO = new RequestVO();
        requestVO.setPid("xiaowugege");
        playerOnLoginService.initPlayerInfo(requestVO);
        log.info("结束测试");
    }

}
```

```java
@Slf4j
@Service
public class PlayerOnLoginService {

    @Autowired
    ApplicationEventPublisher publisher;

    @Async
    public void initPlayerInfo(RequestVO requestVO) {
        log.info("异步推送玩家初始化数据信息..");
        final PlayerOnLoginEvent<RequestVO> playerOnLoginEvent = new PlayerOnLoginEvent<>(requestVO);
        publisher.publishEvent(playerOnLoginEvent);
    }
}
```

```java
@Component
@Slf4j
public class BaseInfoController {

    @EventListener
    @Order(0)
    public void initPlayerInfo(PlayerOnLoginEvent<RequestVO> playerOnLoginEvent){
        log.info("初始化基础信息:{}",playerOnLoginEvent.getRequestVO());
    }
}
```
