当配置设置为另一个时，Idea + Spring Boot + Tomcat 在端口 8080 上启动

【中文标题】当配置设置为另一个时，Idea + Spring Boot + Tomcat 在端口 8080 上启动【英文标题】：Idea + Spring Boot + Tomcat start on port 8080 when config set to another 【发布时间】：2018-02-23 03:30:24 【问题描述】：

我有一个 Spring Boot 应用程序。（使用开发工具、执行器、尤里卡、启动器安全性）。有时，当我使用 Idea（通过主类 - 运行）启动我的应用程序时，它试图在端口 8080 上启动，而在我的 application.yml 中设置另一个端口。

我注意到当我在 git 中切换分支并重新启动服务时会发生这种情况。它崩溃了。我再次启动它 - 一切正常，正常启动。

application.yml 的一部分：

spring:
  application:
      name: discovery-service
server:
  port: 1111

eureka:
  instance:
    hostname: localhost
  client:
    register-with-eureka: false
    fetch-registry: false
  server:
    enableSelfPreservation: false

security:
  basic:
    enabled: true
  user:
    name: user
    password: password

endpoints:
  enabled: false
  health:
    id: healthcheck
    enabled: true

management:
  health:
    defaults:
      enabled: false

这是崩溃时的 eureka 日志。如您所见，Tomcat 端口为 8080。我正在使用嵌入式 tomcat。

Tomcat 使用端口初始化：8080 (http)

【问题讨论】：

当您更改配置文件时。先重建项目。 【参考方案1】：

你在你的项目中使用spring cloud吗？如果你在 pom 文件中添加 spring cloud 你必须从 pom 中删除或者你需要在你的 application.yml 文件中配置 spring cloud 配置。

【讨论】：

是的，我用的是spring cloud。在 pom 中设置所有依赖项（在我的情况下是 build.gradle），并进行配置。你能把你所有的 application.yml 都发过来吗？将其添加到帖子的第一个。

以上是关于当配置设置为另一个时，Idea + Spring Boot + Tomcat 在端口 8080 上启动的主要内容，如果未能解决你的问题，请参考以下文章
