@存储库
公共接口CustomerRepo扩展了JpaRepository{
}

我正在使用

JpaRepository

执行数据库操作。当我在应用程序启动时使用

@Autowired

时，请给出上述错误。另外，我是

spring

的新开发人员。我检查了所有出现的问题，但都没有结果。

提前找到帮助，谢谢。

似乎找不到名为“entityManagerFactory”的bean。在config类中，您有一个

getEntityManagerFactoryBean

，但它将成为名为

getEntityManagerFactoryBean

的bean，而不是

entityManagerFactory

尝试将该方法重命名为

entityManagerFactory（）

，如下所示：

@Repository
public interface CustomerRepo extends JpaRepository<CustomerEntity ,String> {

}

此外，您应该让Spring将EMF作为方法参数提供给transactionManager：

@Bean
public LocalEntityManagerFactoryBean entityManagerFactory() {
    LocalEntityManagerFactoryBean factoryBean = new LocalEntityManagerFactoryBean();
    factoryBean.setPersistenceUnitName("springpos");
    return factoryBean;
}

错误消息告诉您没有名为

entityManagerFactory

你的方法

@Bean
public JpaTransactionManager getJpaTransactionManager(EntityManagerFactory emf) {
    JpaTransactionManager transactionManager = new JpaTransactionManager();
    transactionManager.setEntityManagerFactory(emf);
    return transactionManager;
}

返回一个

LocalEntityManage
