java – Spring启动初始化错误

我用spring初始化工具生成一些工作骨架,
我采用MAVEN PROJECT& amp; JAVA& SPRING BOOT 2.0.0

https://start.spring.io/

当我运行mvn clean install(没有在项目中做任何更改)时,我得到了以下错误,任何想法如何克服它？

更新

这是pom.xml文件,我没有改变任何东西……

spring-boot-starter-parent.sourceEncoding>UTF-8.sourceEncoding>
        spring-boot-starter-data-restspring-boot-starter-hateoasspring-boot-starter-jerseyspring-boot-starter-securityspring-boot-starter-webspring-boot-starter-tomcatcope>providedcope>
        spring-boot-starter-testcope>testcope>
        ecurityecurity-testcope>testcope>
        

UPDATE2

spring-boot-starter-parent.sourceEncoding>UTF-8.sourceEncoding>
    spring-boot-starter-data-restspring-boot-starter-hateoasspring-boot-starter-jerseyspring-boot-starter-securityspring-boot-starter-webspring-boot-starter-tomcatcope>providedcope>
    spring-boot-starter-testcope>testcope>
    ecurityecurity-testcope>testcope>
    

最佳答案

可能是您添加的依赖项

spring-boot-starter-data-rest

似乎在初始化时需要数据库连接,可能在application.properties文件上提供数据库连接或删除此依赖关系,直到数据库构造可能对您有所帮助.

另外要确定原因,请分享您的application.properties文件
