一旦创建了一个名为entity的程序包并在application.yml中添加了一些配置，该错误就会消失

application.yml看起来像这样

spring:
  datasource:
    url: jdbc:mysql://localhost:3306/mydb
    username: root
    password:
  jpa:
    show-sql: true
    hibernate:
      ddl-auto: update
      naming:
        strategy: org.hibernate.cfg.ImprovedNamingStrategy
    properties:
      hibernate:
        dialect: org.hibernate.dialect.MySQL5Dialect

我试图用'mvn clean install'重建项目
我试着从maven依赖项中删除所有* .jars，并从maven函数中使用了“更新项目”。

我的pom.xml看起来像这样:

我是Spring MVC，Maven和Spring Boot的新手。任何帮助将非常感激。

** 更新 **
顺便说一句我使用Eclipse NEON 2

Answer 1

如果确定在pom.xml中定义了所有适当的依赖项，则可能是本地maven存储库中的jar或pom错误。

您可以使用以下命令清除本地存储库

mvn dependency:purge-local-repository

这将在再次重建( mvn package)时从本地存储库中删除所有项目依赖项，这些依赖项将得到解决并重新下载。

您还可以指定一些其他标志(请参阅 this question和 official documentation)。
