获取错误没有定义[javax.persistence.EntityManagerFactory]类型的限定bean：应为单个匹配bean，但找到2

我今天有同样的问题。解决了以下问题：

首先，我将参数unitName添加到@PersistenceContext到两个实体管理器属性：

@PersistenceContext(unitName="appPU")@Qualifier(value = "appEntityManagerFactory")private EntityManager appEntityManager;@PersistenceContext(unitName="managerPU")@Qualifier(value = "managerEntityManagerFactory")private EntityManager managerEntityManager;

在我的配置文件中，我向bean定义添加了一个属性persistenceUnitName：

<bean id="appEntityManagerFactory" >    <property name="dataSource" ref="dataSource1" />    <property name="persistenceUnitName" value="appPU" />    <property name="packagesToScan" value="br.com.app.domain" />    ...</bean><bean id="managerEntityManagerFactory" >    <property name="dataSource" ref="dataSource2" />    <property name="persistenceUnitName" value="managerPU" />    <property name="packagesToScan" value="br.com.app.domain" />    ...</bean>
