SpringBoot 找不到 EntityManagerFactory 即使它被声明答案

【问题标题】：SpringBoot can't find EntityManagerFactory even though it is declaredSpringBoot 找不到 EntityManagerFactory 即使它被声明
【发布时间】：2022-01-27 21:02:28
【问题描述】：

我有这个 SpringBoot 代码。它同时加载 mybatis 和 hibernate。我收到关于 EntityManagerFactory 类型的 bean 不可用的异常，但它是在此处定义的。包含“xxx”的日志输出全部打印。

标签： spring-boot hibernate entitymanager

【解决方案1】：

通过在 application.properties 中设置克服了这个错误：

 spring.jpa.open-in-view=false

不知道这里发生了什么。
