未找到EntityManger bean？

Question

启动ApplicationContext时出错。若要显示条件报告，请在启用“调试”的情况下重新运行应用程序。2017-11-21 15:46:26.983错误6272---[main]O.S.B.D.LoggingFailureAnalysisReporter
应用程序无法启动****************************************************************

描述：com.learing.demo.StatusService中的字段存储库需要一个名为“Entity ManagerFactory”的bean，但找不到该bean。行动：

考虑在配置中定义一个名为'Entity ManagerFactory‘的bean。
