在 heroku 中運行 Spring boot 應用程式時出現 R10 錯誤。我嘗試了 Stack Overflow 中的大部分建議，但它們對我不起作用。
請幫我..

我不明白為什么會出現 R10 錯誤。
在本地，我的代碼非常適合運行服務器。（作業得很好）
uj5u.com熱心網友回復：
您的埠似乎是正確的。我不是 Spring 方面的專家，但我認為您只需要在 as 中application.properties或在Procfileas中設定一次-Dserver.port=$PORT。你已經完成了這兩件事。我不認為--server.port=$PORT做任何事情。
但是，您還設定server.address=localhost了application.properties. 假設指定了服務器應該監聽的介面，那是不正確的。localhost可能無法從測功機本身外部接收流量。
嘗試將其更改為server.address=0.0.0.0，然后提交并重新部署。這應該指示 Tomcat 偵聽所有可用的 IP 地址。
