Spring Boot Tomcat 无法启动。初始化并停止答案

【问题标题】：Spring Boot Tomcat can't start. Initializes and is stoppedSpring Boot Tomcat 无法启动。初始化并停止
【发布时间】：2021-05-31 21:25:14
【问题描述】：

我正在从事两个 Spring Boot 项目。一个运行正常，但另一个启动正常，然后停止 Tomcat。然后它会抛出一个异常，说 tomcat 嵌入式服务器无法启动。

原因：java.net.BindException：无法分配请求的地址

下面是输出。

我已经尝试了一切合乎逻辑的方法。不知道下一步该做什么。

更新：以下是我尝试过的一些事情。

删除了 .m2/repository 并重新安装了依赖项。
已检查运行的 Tomcat 实例。
检查端口可用性。（也尝试了不同的帖子编号）

【问题讨论】：

应用程序尝试监听的端口是免费的吗？您是否在同一端口（默认为 8080）和同一设备上启动这两个应用程序？
你能edit你的问题具体描述一下你已经尝试过什么吗？这可能会节省一些“试试这个......”，“我已经做过......” cmets。（否则，端口似乎是最可能的原因。）

【解决方案1】：

所以我发现了我的问题。我有一个名为“SERVER_ADDRESS”的环境变量设置，似乎这导致了tomcat请求和获取有效地址的一些问题。我将其更改为其他内容并修复了它。
