我创建了一个Spring Boot应用程序，并使用要执行的方法创建了一个类。当将项目部署为war文件时，我从stacktrace中得到了错误。我想从TennisExecutor类运行该方法。
我将显示代码的某些部分：

我试图删除.m2 / repository文件夹，添加了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的，但是它不起作用。 有人有什么建议吗？
答案 0 :(得分：0)
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>
答案 1 :(得分：0)
Sampada 解决方案有效。干得好:)
