Spring Boot 2.7连接H2数据库报错：找不到mem:testdb求解决

我在尝试连接H2控制台时遇到如下错误：

Database “mem:testdb” not found, either pre-create it or allow remote database creation.

我做了以下排查但问题仍未解决：

• 查阅过类似问题的解决方案，说需要复制控制台显示的JDBC URL，但我的控制台没有这个提示（附截图）。
• 检查过application.properties配置（附截图），尝试添加spring.datasource.generate-unique-name=false但无效。
• 确认POM文件中H2依赖、devtools等均已正确添加（项目通过Spring Initializr创建），POM配置如下：

请问有什么解决思路吗？
