当我在本地运行我的spring项目时，我没有任何异常。但是当在服务器上部署时，我得到：

... 16 more我正在使用Spring Data Jpa和repository类扩展JpaRepository。在日志中，我发现方法getBlockNumberPair中的BlockNumberService有问题。这是我的方法的外观：
@Transactional(readOnly = true)
@Override
public BlockNumber getBlockNumberPair() {
return blockNumberRepository.findById(1L).get();
}问题出在哪里？为什么它在当地有效？

通过重新启动服务器解决。
更新日期：
这是Jenkins中的配置错误。我只是把我的项目推到Github中，Jenkins部署了项目。在Jenkins重新部署之后，我已经启动了和我推到Github中一样多的tomcat服务器，并且在log中我得到了这个异常。但是有趣的是，它是如何在同一个端口启动很多进程的？在这种情况下，服务器不应该启动。
