我正在尝试将我的spring应用程序与mysql db连接，mysql db与app位于同一服务器上。当我启动我的应用程序时，我发现错误“java.sql.sqlexception:access denied for user'root'@'localhost'”
我找到了许多关于“java.sql.sqlexception:access denied for user'root'@'localhost'（using password:yes）”和“java.sql.sqlexception:access denied for user'root'@'localhost'（using password:no）”的解决方案，但在我的例子中，日志中没有任何关于“using password”的信息。
我发现关于“使用密码”这个：① (使用密码：是）：未获取用户名② (使用密码：否）：未获取密码
我的错误是什么意思？
我的根用户拥有所有权限，我可以从命令行使用它连接到db。
我的pom.xml：

spring.jpa.hibernate.ddl-auto=update
spring.datasource.url=jdbc:mysql://localhost:3306/web_blog_db
spring.datasource.username=root
spring.datasource.password=*mypass*
spring.jpa.show-sql=true
server.error.whitelabel.enabled=false

日志：
