我有一个Sping Boot 应用程序，它在IntelliJ上运行得很好。然后我试图构建一个在out/target文件夹中创建的工件。试图用java -jar Backend.jar运行创建的工件会导致此错误

字符串
在我的application.yml中，它被定义为

  1. spring:
  3.   datasource:
  4.     url: jdbc:postgresql://localhost:5432/openbarber
  5.     username: postgres
  6.     password: admin

是什么导致了这个错误？我认为是艺术品出了问题？

确保您的maven配置中有spring Boot 插件，如参考资料https://docs.spring.io/spring-boot/docs/1.1.x/reference/html/howto-build.html中所述。

  1. <build>
  2.     <plugins>
  3.         <plugin>
  4.             <groupId>org.springframework.boot</groupId>
  5.             <artifactId>spring-boot-maven-plugin</artifactId>
  6.         </plugin>
  7.     </plugins>
  8. </build>

然后只需运行通常的干净安装，以打包您的应用程序

  1. mvn clean install

在没有看到pom的情况下，很难评估问题，但是如果这不能解决问题，也可能与您的依赖关系有关
