Spring boot 2.2.1-無法啟動嵌入tomcat（日志中沒有錯誤）

Question

我正在開發一個版本2.2.1RELEASE的Spring Boot應用程序。應用程序結構，我已將配置作為外部配置移動到 config 文件夾中。項目結構應該是這樣的

當我運行我的應用程序時，它顯示以下日志

我嘗試了以下可能的解決方案。

• 更新和清理我的項目。
• 刪除.m2存儲庫並參考以下堆棧鏈接。

1. Spring Boot 應用程序沒有啟動嵌入式tomcat

2. 部署在tomcat上的spring boot無法啟動

還沒有得到任何解決方案。

注意：-注意到我的日志中有兩行

2019-12-12 20:34:45.086  INFO 375592 --- [           main] .s.d.r.c.RepositoryConfigurationDelegate : Bootstrapping Spring Data repositories in DEFAULT mode.

Answer 1

這可能是由於接口與帶有 @SpringBootApplication 注釋的主類不在同一級別上造成的。

這是一個例子。

請注意，所有子包都與@SpringBootApplication 處於同一級別。
