答案 0 :(得分：0)
问题似乎是'entityManagerFactory'没有定义。几天前我遇到了类似的问题。尝试使用以下方法交换entityManagerConfig的方法标题和返回类型：
@Bean
public EntityManagerFactory entityManagerFactory() {
...
return entityManagerFactoryBean.getObject();
}
答案 1 :(得分：0)
在entityManagerConfig班级中将entityManagerFactory替换为Config.java，如下所示 -
@Bean
LocalContainerEntityManagerFactoryBean entityManagerFactory(DataSource datasource)
这将确保使用名称entityManagerFactory创建bean，该名称是EntityManagerFactory的默认名称。
来自此Spring Data JPA文档 -
entityManagerFactoryRefpublic abstract String entityManagerFactoryRef配置名称 要用于创建的EntityManagerFactory bean定义 通过此注释发现的存储库。默认为 的entityManagerFactory。
返回：
默认： “的entityManagerFactory”
