Can't run my Springboot/Oracle application. Port problems
提问by Martin Erlic
I'm trying to run my Springboot application. I need to connect to my Oracle database but I'm getting an error related to the port that it is installed on. It's an Oracle 11g Express Edition installation. Should I then change the port of my Oracle installation and if so, how?
我正在尝试运行我的 Springboot 应用程序。我需要连接到我的 Oracle 数据库，但我收到一个与安装它的端口相关的错误。这是一个 Oracle 11g Express Edition 安装。然后我是否应该更改我的 Oracle 安装的端口，如果是，如何更改？

APPLICATION FAILED TO START

Description:
The Tomcat connector configured to listen on port 8080 failed to start. The port may already be in use or the connector may be misconfigured.
Action:
Verify the connector's configuration, identify and stop any process that's listening on port 8080, or configure this application to listen on another port.

Solution to your Question
Two Possible ways
1. Please change your Oracle Port to some other Port like 8081 or 9080.
2. Change the Tomcat Port in Spring-Boot application properties file.
3. Add the below following lines in src/main/resources/application.properties
您的问题的解决方案
两种可能的方法
1. 请将您的 Oracle 端口更改为其他端口，例如 8081 或 9080。
2. 在 Spring-Boot 应用程序属性文件中更改 Tomcat 端口。
3. 在 src/main/resources/ application.properties 中添加以下几行
server.port=8081.
回答by Siick
I had the same problem because i closed Eclipse suddenly with my springboot app still running and the JAVA process was still running in background. That's why the port was in use in my case.
我遇到了同样的问题，因为我突然关闭了 Eclipse，我的 springboot 应用程序仍在运行并且 JAVA 进程仍在后台运行。这就是为什么在我的情况下使用端口的原因。
