当我建立项目时，它会在Hikariool-1上阻塞-开始

以下是完整的stacktrace：

调试时，我在一个循环中收到3条消息：

感谢您的回答

请尝试在

应用程序.properties

中更改这些行

spring.datasource.url=jdbc:postgresql://127.0.0.1:5432/postgres

---

您的

spring.datasource.url

中似乎有太多的

postgres

条目。您的

spring.datasource.url

是否应该在最后只有一个

postgres

？同样的情况，我只是为了测试而尝试了这个方法。如果您将端口号更改为您知道postgres没有运行的某个随机端口，是否会出现

连接被拒绝

错误或类似的其他错误？同样的情况，谢谢，问题解决了，我正在管理控制台使用的端口上运行应用程序
