Spring 使用@Async出現循環依賴Bean問題

報錯信息：

2020-06-01 12:14:15 [main] WARN  o.s.b.w.s.c.AnnotationConfigServletWebServerApplicationContext - Exception encountered during context initialization - cancelling refresh attempt: org.springframework.beans.factory.BeanCurrentlyInCreationException: Error creating bean with name 'asyncTaskImpl': Bean with name 'asyncTaskImpl' has been injected into other beans [capaStatCacheComponent,streamLineServiceImpl,sboxSetServiceImpl,streamBoxServiceImpl] 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 'getBeanNamesOfType' with the 'allowEagerInit' flag turned off, for example.

上面描述的報錯信息就是出現循環依賴Bean問題

解決方案：

 

業務層注入異步方法類,使用 @Lazy+@Autowired

@Autowired
@Lazy
private AsyncTask asyncTask;

 

 

異步方法類

@Component
public class AsyncTaskImpl implements AsyncTask {
    @Autowired
    private StreamService streamService;
    @Autowired
    private MacmsFeignApi macmsFeignApi;

...
...
}
