例外：类型为'；org.springframework.boot.orm.jpa.EntityManagerFactoryBuilder'；那是找不到的

我在连接hibernate实体管理器时遇到以下错误，sql和应用程序启动失败。Springboot版本2.0.5.0发布

说明：

****中imdbEntityManager方法的参数1需要一个 键入“org.springframework.boot.orm.jpa.EntityManagerFactoryBuilder” 那是找不到的

行动：

考虑定义类型为的bean 您的应用程序中的“org.springframework.boot.orm.jpa.EntityManagerFactoryBuilder” 配置

我已经在stackoverflow中查看了多个答案，目前没有任何帮助

请发布您的pom.xml（或Gradle文件）添加的pom@eugen现在也有同样的问题，但它在另一个项目中运行良好。试图找出差异。。。希望很快会有答案。好吧，在我的例子中，我有一个多数据源配置，当我将其中一个数据源注释为

@Primary

（这毫无意义）时，问题就消失了。但是您的配置似乎是一个单一的数据源，而且您确实有

@Primary

注释。
