注意，这两个文件中的所有内容都相似，只是第二个文件中的

现在，当我运行项目时，我得到以下异常：

 org.springframework.beans.factory.NoUniqueBeanDefinitionException: No qualifying bean of type [javax.persistence.EntityManagerFactory] is defined: expected single matching bean but found 2: commonEntityManagerFactory,profileEntityManagerFactory

我已经在这个例外中呆了两天了。谁能帮我解决这个问题。谢谢您的时间。

不确定它是否对您有帮助，但请尝试将

commonEntityManagerFactory（）

和

profileEntityManagerFactory（）

的返回值从

EntityManagerFactory

更改为

LocalContainerEntityManagerFactoryBean

，并返回这些工厂实例，而不是

factory.getObject（）

。这是我目前项目中的一些东西，它工作得很好

另一个猜测：您使用哪个Spring框架版本？问题是，最近Spring框架中出现了一个与您的问题相关的回归。看一看，举个例子。回归系数为4.1.4。如果您确信您的配置是正确的，请尝试使用不同的Spring版本。希望这有帮助

您没有将

“common”

定义为一个单元名，并且您有两个

@Primary

注释。尝试配置：

@Bean（name=“common”）

而不是

@Bean（name=“commonEntityManagerFactory”）

您没有将

“common”

定义为一个unitName，并且您有两个

@Primary

注释。尝试配置：

@Bean（name=“common”）

而不是

@Bean（name=“commonEntityManagerFactory”）

因为它是Spring Jpa配置，所以您可能需要这样做：
