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
最佳答案
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)。
