項目啓動的時候報瞭如下的錯誤：
Error creating bean with name 'boingpayCallbackController': Unsatisfied dependency expressed through field 'transitToCashService'; nested exception is org.springframework.beans.factory.BeanCurrentlyInCreationException: Error creating bean with name 'transitToCashService': Bean with name 'transitToCashService' has been injected into other beans [flowCheckCore,bankFlowCheckService,checkLogService] 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.

分析：
看了下報的是循環依賴的錯誤，但是Spring單例是支持循環依賴的,然後網上搜索發現是因爲transitToCashService這個類中的方法有加**@Async**註解（只需要類/方法有標註@Async註解的Bean最終都會生成一個代理對象重新賦值並add進Spring容器內）。
解決辦法：
不要讓@Async的Bean參與循環依賴
使用@Lazy或者@ComponentScan(lazyInit = true)
通過後置處理器設置allowRawInjectionDespiteWrapping=true（@Aysnc方法將不起作用）
