我有两个用于两个独立数据库的实体管理器配置，但是当我尝试自动连接实体管理器以配置我的 GraphQLExecutor bean 时，我收到一个异常，指出即使我指定了一个单元名称，仍有两个 bean 符合条件在 PersistenceContext 中。

例外

org.springframework.beans.factory.BeanCreationException：创建名为“graphQLExecutor”的bean时出错：资源依赖注入失败；嵌套异常是 org.springframework.beans.factory.NoUniqueBeanDefinitionException：没有可用的“javax.persistence.EntityManager”类型的合格 bean：预期的单个匹配 bean，但发现 2：org.springframework.orm.jpa.SharedEntityManagerCreator#0,org.springframework .orm.jpa.SharedEntityManagerCreator#1 at org.springframework.context.annotation.CommonAnnotationBeanPostProcessor.postProcessPropertyValues(CommonAnnotationBeanPostProcessor.java:321) ~[spring-context-4.3.9.RELEASE.jar:4.3.9.org.RELEASE] springframework.beans.factory.support.AbstractAutowireCapableBeanFactory.populateBean(AbstractAutowireCapableBeanFactory.java:1264) ~[spring-beans-4.3.9.
