Spring boot Spring引导组件扫描在maven多模块项目中不起作用

我遵循了spring官方项目指南，以下是我的项目。当我使用

/mvnw安装&&./mvnw-spring-boot:run-pl-user

运行其中一个模块时，它失败了，出现以下日志

如果我在配置中提供一个

ServletWebServerFactory

bean，它会抱怨找不到其他bean

。。。
@豆子
公共ServletWebServerFactory ServletWebServerFactory（）{
返回新的TomcatServletWebServerFactory（）；
}

这是我的申请表：

我还尝试直接使用

@ComponentScan

，它有相同的结果。

它似乎与在main类中使用

SpringApplicationBuilder

有关。如果我将main类更改为最简单的类，它运行正常

package net.jaggerwang.scip.user.api；
导入com.oembedler.moon.graphql.boot.GraphQLWebsocketAutoConfiguration；
导入org.springframework.boot.SpringApplication；

@EnableJpaRepositories（“net.jaggerwang.scip.user.adapter.repository.jpa”）
公共类SCIP应用程序{
公共静态void main（字符串[]args）{
run（ScipApplication.class，args）；
}
}

Tomcat的一个JAR在下载时可能已被Maven损坏。尝试清除Maven的缓存并重建应用程序。
