在本地计算机上一切正常。但是，当移植到服务器时，启动时会发生错误：

找到问题的根源，使我想到组装的WAR中jpa实现的版本过多。它发生了。在/ WEB-INF / lib /中，我发现了许多与jpa相关的库。他们在这里：

hibernate-jpa-2.1-api-1.0.2.Final.jar
spring-boot-starter-data-jpa-2.0.4.RELEASE.jar
spring-data-jpa-2.0.9.RELEASE.jar

以下是带有完整库列表的屏幕截图：

该项目来自另一个人，我无法说说它是如何发生的，因为在pom中，我没有发现任何多余的东西。我不明白现在如何只剩下您需要的东西，而丢弃所有多余的东西，最重要的问题是，太多的jpa可能会发生冲突？

Spring Boot-使用名称创建bean时出错（JPA实现冲突）
