我正在嘗試使用基本Pet Clinic應用程序和Spring-Boot基礎創建增強型寵物診所。我使用了以下內容：在Spring Boot中引入AOP（使用JavaConfig）會導致嵌入式Tomcat無法啓動
- 彈簧引導起動thymeleaf
- 彈簧引導起動數據JPA
- 彈簧引導啓動的Web
當我添加帶註釋@Aspect，@Configuration和@Component的類的spring-boot-starter-aop（我不認爲我需要全部3個，但是如果我有@Aspect和其他2個註釋中的任何一個，則失敗），該應用程序無法啓動時出現以下錯誤：

只要將註釋添加到該類中，我就開始使用Tomcat啓動時出現這些問題，這似乎與org.springframework.beans.factory.BeanCreationExceptions有關。
有沒有人有任何想法，爲什麼簡單地添加AOP啓動程序和註釋類可以災難性地打倒Tomcat？
該應用程序可以在GitHub找到。
刪除'@ Component'和'@ Configuration'並簡單地添加一個'@ Bean'方法來構造您的'@Aspect' bean的一個實例。 Spring使用代理來應用AOP，默認情況下，代理使用JDK Dynamic Proxies（基於接口）完成。所以可能你的方面導致代理所有的豆（檢查你的切入點）。 –
