我试图在我的机器上运行一个小的基本Spring启动程序,当我在maven上运行干净编译(甚至在尝试spring-boot：run之前)时,我得到以下错误：

这是我的java类：
package com.benayed.spboot.poc.SpringBootPoc;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
@SpringBootApplication
public class SpringBootPocApplication {
public static void main(String[] args) {
SpringApplication.run(SpringBootPocApplication.class, args);
}
}
我尝试了很多可以在互联网上找到的解决方案,例如删除.m2存储库,在spring-boot-maven-plugin插件中添加不同的标签(版本,分叉……),我很确定,这是引起问题的部分
有什么建议么 ？
解决方法:
你有0个编译依赖项,只定义了测试编译依赖项,因为你已经注释掉了spring-boot-starter-data-jpa. Spring starter将其他依赖项(包括其他启动器)拉入其中以创建编译时所需的所有内容.取消注释spring-boot-starter-data-jpa依赖关系,和/或重新评估您实际需要的依赖关系.
