java - 在sts嵌入的apache tomcat服务器无法启动

Question

我对 Spring 和 Spring Boot 应用程序很陌生。创建类路径资源中定义的名称为“entityManagerFactory”的 bean 时出错。它说无法构建 EntityManagerFactory。控制台中显示错误:

1. 当我尝试运行嵌入式 apache tomcat 时，出现此错误
2. 请告诉我出了什么问题

通常，无效的 LOC header 意味着您的本地 Maven 存储库已损坏。进入~/.m2/repository目录，找到hibernate目录，删除它，然后重建项目。
