[英]Spring boot initialization error
我使用spring初始化工具生成一些工作骨架,我使用MAVEN PROJECT&JAVA&SPRING BOOT 2.0.0默認
當我運行mvn clean install
(沒有在項目中做任何更改)時,我得到了以下錯誤,任何想法如何克服它?

這是pom.xml文件,我沒有改變任何東西......

可能是您添加的依賴項
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-data-rest</artifactId>
</dependency>
似乎在初始化時需要數據庫連接,可能在application.properties文件上提供數據庫連接或刪除此依賴關系,直到數據庫構造可能對您有所幫助。
另外要確定原因,請分享您的application.properties文件
