[英]Spring Boot app keeps crashing on startup even with spring-boot-starter-web dependency
[英]Error on Spring Boot App Startup when adding spring-boot-starter-web
使用spring-cloud-starter-aws-secrets-manager-config
啟動一個非常基本的Spring boot應用程序以檢索AWS sectrets
可以正常工作。 但是,當我將spring-boot-starter-web dependency
到項目中以提供Web服務支持時, the spring-cloud-starter-aws-secrets-manager-config
errors
導致應用程序無法啟動。

應用程序應正常啟動,但是應用程序出現以下錯誤:
啟動ApplicationContext時出錯。 要顯示自動配置報告,請在啟用“調試”的情況下重新運行您的應用程序。 2019-07-03 11:57:16.563錯誤73839 --- [main] osboot.SpringApplication:應用程序啟動失敗

您正在混合1.5.x和2.x依賴項。 由於這兩個版本之間存在重大更改,因此在同一項目中同時使用這兩個版本時,經常會出現兼容性問題。
由於spring-cloud-starter-aws-secrets-manager-config僅支持2.x,因此您需要將spring boot starter parent升級到2.x版本。
@Michael McFadyen的回復是正確的; 但是,值得注意的是,手動添加Spring Cloud依賴及其版本不是一個好習慣。 應該改用dependencyManagement
插件和Spring Cloud Release火車,以確保使用的所有Spring Cloud庫都處於兼容版本中。請參閱項目頁面中的“發行火車”部分。 它還包含有關哪些發行版與哪個Spring Boot版本相對應的信息。
如果要確保在構建文件中正確設置了Spring依賴項,則可以轉到start.spring.io生成具有正確構建文件的項目存根。
