问题重现

定义一个类A
（1）实现SmartApplicationListener接口
（2）在重写的onApplicationEvent方法上定义@Async注解
（3）在类中注入其它服务的Feign接口对象
示例如下：

@Slf4j
@Component
public class A implements SmartApplicationListener {
@Autowired
private FeignX feignX;
@Override
public boolean supportsEventType(Class<? extends ApplicationEvent> eventType) {
return eventType == XXXEvent.class;
}
@Async
@Override
public void onApplicationEvent(ApplicationEvent event) {
}
}

满足上述3个条件后，启动服务出现如下错误：
Bean with name 'a' has been injected into other beans [xxx.feign.FeignX] in its raw version as part of a circular reference, but has eventually been wrapped. This means that said other beans do not use the final version of the bean. This is often the result of over-eager type matching - consider using 'getBeanNamesForType' with the 'allowEagerInit' flag turned off

问题原因

待考究

解决方案

不实现SmartApplicationListener接口，改用@EventListener注解定义处理方法

@Slf4j
@Component
public class A {
@Autowired
private FeignX feignX;
@EventListener
@Async
@Override
public void onApplicationEvent(XXXEvent event) {
}
}
