Question

我正在创建一个新项目，其依赖项的pom.xml文件如下所示

SearchedUser

但是，其中3个依赖项似乎有一些问题。为什么会这样呢？我该如何纠正？

更新

我添加了此 application.properties

       </project>

在执行Maven安装时不会出现任何错误。

spring.jpa.hibernate.ddl-auto=validate
spring.datasource.url=jdbc:mysql://localhost:3306/my_database
spring.datasource.username=root
spring.datasource.password=

但是我的依存关系仍然存在相同的问题。

请参阅有关添加数据源属性的Spring Boot的Connection to a Production Database参考

DataSource配置由spring.datasource。*中的外部配置属性控制。例如，您可以在application.properties中声明以下部分：
spring.datasource.url=jdbc:mysql://localhost/test
spring.datasource.username=dbuser
spring.datasource.password=dbpass
spring.datasource.driver-class-name=com.mysql.jdbc.Driver
