无法运行我的 Spring Boot/Oracle 应用程序。端口问题

Question

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。然后我应该更改我的 Oracle 安装的端口吗？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.

Answer 1

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

中添加以下行

server.port=8081.

Answer 2

我遇到了同样的问题，因为我突然关闭了 Eclipse，而我的 springboot 应用程序仍在运行，而 JAVA 进程仍在后台运行。这就是我使用该端口的原因。
