我已经用PostgreSQL数据库创建了Spring Boot Gradle应用程序，并部署在heroku 上

To https://git.heroku.com/lawcase.git
464da17..2c2db7c main -> main
使用此URL在heroku上部署应用程序https://lawcase.herokuapp.com，我在我的Spring Boot应用程序中开发了Rest API，我还添加了ProcFile
web: java -jar build/libs/LawCase-0.0.1-SNAPSHOT-plain.jar
但当我尝试使用Postman 使用URL访问API时
https://lawcase.herokuapp.com/getprofiles
我得到503服务不可用
这是heroku日志

我尝试了来自stackoverflow 的不同解决方案
Heroku jar部署带有Maven应用程序的Spring Boot，给出代码=H10
部署SpringBoot应用程序时的Heroku错误代码H10
Heroku上的弹簧靴-H10"；应用程序崩溃"；
如何在Spring Boot和Heroku上的GET/POST之后解决503(服务不可用(？
heroku[web.1]：状态从启动更改为崩溃
但我无法解决我的问题，我的应用程序也不工作，有人能帮助我如何在Heroku上正确部署和升级我的应用吗。
因为我不能发表评论而回答。几个想法。Spring Boot应用程序可能不需要Procfile，因为它有一个内置的web服务器(除非你想覆盖某些内容(。还发现了类似的情况，其中是postgres驱动程序问题。
