无法配置DataSource:未指定'url'属性,也无法配置嵌入数据源

我正在使用MongoDB 开发Spring Boot Batch示例,并且已经启动了Mongod服务器

当我启动我的应用程序时,我收到以下错误.

这个问题有什么指针吗？

属性"security.basic.enabled"已弃用:安全自动配置不再可自定义

我正在使用spring-boot-starter-parent版本2.0.1.RELEASE开发Spring Cloud项目.

我低于警告,看起来像

属性"security.basic.enabled"已弃用:安全自动配置不再可自定义.请改为提供您自己的WebSecurityConfigurer bean.

security:basic:enabled:在Spring安全最新版本中禁用false.

你能指导一下我应该用什么代替吗？

更正应用程序的类路径，使其包含 org.axonframework.eventsourcing.eventstore.jpa 的单个兼容版本

我正在研究Spring Boot + Axon示例。遵循youtube 上的https://www.youtube.com/watch?v=lBKZOTe9QM4&list=PL4O1nDpoa5KTq5QKX9ueK-0QCJ-6Wm_ma链接并使用最新的依赖项。

如果我使用axon-core和axon-amqp版本到3.0-RC1那么它工作正常。但是我使用 3.4 版本，然后在启动时出现以下错误。任何快速帮助？
