Question

我正在制作一个angular + spring应用程序，并试图将其部署在同一服务器上。当我分别创建后端时，它在所有过程中均正常运行。但是当我在spring项目中复制我的角度项目并在pom.xml中配置并更新了我的maven并尝试运行该项目时，它开始给我以下错误

Description:

Field beneficiaryRepo in 
com.accounts.rtgsneft.service.BeneficiaryMasterServiceImpl required a bean 
named 'entityManagerFactory' that could not be found.

The injection point has the following annotations:
- @org.springframework.beans.factory.annotation.Autowired(required=true)


Action:

Consider defining a bean named 'entityManagerFactory' in your configuration.

我已经尝试了所有堆栈上的解决方案，但是没有一个起作用。

这是我尝试过的解决方案：

这是我在调试时尝试的解决方案。

我希望有足够的数据来找出问题所在。

如果还有其他解决方案，请推荐给我。我正在使用Spring 2.17 我想在tomcat中部署应用程序war文件，在此之前，我必须对其进行测试以检查其是否仍在工作。

Answer 1

Spring Data JPA默认情况下会查找一个名为EntityManagerFactory的EntityManagerFactory。请查看EnableJpaRepositories的Javadoc的这一部分或Spring Data JPA文档的表2.1。

这意味着您必须将emf bean重命名为entityManagerFactory或将Spring配置更改为：

（如果您使用的是XML）

或

@EnableJpaRepositories（basePackages =“ your.package”，entityManagerFactoryRef =“ emf”）

（如果您使用的是Java Config）

存储库类要求找不到bean的entityManagerFactory
