java.sql.SQLException:拒绝用户访问'；根'@'；本地主机'；没有关于“的任何信息”；使用密码"；

我正在尝试将我的spring应用程序与mysql db连接，mysql db与我的应用程序位于同一服务器上。 启动应用程序时，我发现错误“java.sql.SQLException:拒绝用户'root'@'localhost'的访问”

我找到了许多关于“java.sql.SQLException:Access denied for user'root'@'localhost”（使用密码：YES）和“java.sql.SQLException:Access denied for user'root'@'localhost”（使用密码：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

我发现有关“使用密码”的信息如下： 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root用户拥有所有权限，我可以从命令行使用它连接到db

My 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：
