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.

>

启动ApplicationContext时出错。若要显示自动配置报告，请在启用“debug”的情况下重新运行应用程序

设置构造函数参数时无法解析对bean“Entity ManagerFactory”的引用

找不到名为“Entity ManagerFactory”的bean

Field repository需要一个名为“Entity ManagerFactory”的bean，但找不到该bean

Spring数据JPA-没有定义名为'Entity ManagerFactory‘的bean；自动连线依赖项注入失败

这是我在调试时尝试的解决方案。

如果有其他的解决方案，请推荐给我。我使用的是Spring2.17，我想在tomcat中部署应用程序war文件，在这样做之前，我必须对它进行测试，以检查它是否还在工作。

Answer 1

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

这意味着您要么必须将emf bean重命名为entityManagerFactory,要么将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配置）
