hibernate - 没有名为 'entityManagerFactory' 的可用 bean

Question

我创建了一个 Spring Boot 应用程序，并使用我想要执行的方法创建了一个类。将项目部署为 war 文件时，我从堆栈跟踪中收到错误。我想运行 TennisExecutor 类中的方法。

• 没有名为“entityManagerFactory”的可用 Bean
• 创建名称为“(inner bean)#366583f9”的 bean 时出错:设置构造函数参数时无法解析对 bean“entityManagerFactory”的引用；嵌套异常是org.springframework.beans.factory.NoSuchBeanDefinitionException:没有名为“entityManagerFactory”的bean可用

我将展示我的代码的某些部分:

我尝试删除 .m2/repository 文件夹，添加 spring-data-jpa 的依赖项，但没有任何变化。另外，我尝试配置数据源以实现某些目标，但它不起作用。有人有什么建议吗？

Answer 1

对于 Spring Boot 2，您需要添加此依赖项:

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-data-jpa</artifactId>
</dependency>
