I think this is because my port is used. My port 8080 is used so I try the port 8181 I have no application on the port 8181

我想这是因为我的端口被使用了。我的端口 8080 被使用，所以我尝试端口 8181 我在端口 8181 上没有应用程序

in the tomcat server.xml I set the port to 8181 but the problem persist

在 tomcat server.xml 我将端口设置为 8181 但问题仍然存在

I find this post:

我找到了这个帖子：

Alternate port for Tomcat (not 8080) when starting with Maven?

使用 Maven 时，Tomcat 的备用端口（不是 8080）？

But I have the same problem after launching mvn -Dmaven.tomcat.port=8181 tomcat:run-war

但是在启动 mvn -Dmaven.tomcat.port=8181 tomcat:run-war 后我遇到了同样的问题

I don't realy understand how to maven is linked to the tomcat server This is my pom.xml

不太明白maven是怎么链接到tomcat服务器的 这是我的pom.xml

Spring Boot uses embedded Tomcat by default, but it handles it differently without using tomcat-maven-plugin. To change the port use --server.portparameter for example:

Spring Boot 默认使用嵌入式 Tomcat，但它在不使用tomcat-maven-plugin. 要更改端口使用--server.port参数，例如：

java -jar target/gs-serving-web-content-0.1.0.jar --server.port=8181

Update. Alternatively put server.port=8181into application.properties(or application.yml).

更新。或者把server.port=8181进application.properties（或application.yml）。

Using IntelliJ, I got this error when I tried to run a Spring app while there was one app already running. I had to stop the first one. After that, running the second app didn't return any errors.

使用 IntelliJ 时，当我尝试运行 Spring 应用程序而有一个应用程序已在运行时，我收到了此错误。我不得不停止第一个。之后，运行第二个应用程序没有返回任何错误。

You need to stop the server before re-launching. Look for the red box icon or server view.

您需要在重新启动之前停止服务器。寻找红框图标或服务器视图。

Close the application, then restart it after changing to a new port:

关闭应用程序，然后在更改到新端口后重新启动它：

${port:8181}

You can use any new unused port. Here, I used port 8181.

您可以使用任何新的未使用端口。在这里，我使用了端口 8181。

Configure another port number(eg:8181) in /src/main/resources/application.properties

在/src/main/resources/application.properties 中配置另一个端口号（例如：8181）

server.port=8181

server.port=8181

Run the following command to search for the process that is using the port

运行以下命令搜索正在使用该端口的进程

lsof -i :<portNumber> | grep LISTEN

in your case this will be -->

在你的情况下，这将是 -->

lsof -i :8080 | grep LISTEN
java    78960 xyxss  119u  IPv6 0x6c20d372bc88c27d      0t0  TCP *:8092 (LISTEN)

The 78960 is the process id, use the following command to kill the process

78960是进程id，使用如下命令杀掉进程

kill -9 78960

Launch the application again.

再次启动应用程序。

In my case looking in the servers window only showed a tomcat server that I had never used for this project. My SpringBoot project used an embedded tomcat server and it did not stop when my application finished. This button which I indicate with a red arrow will stop the application and the Tomcat server so next time I run the application I will not get the error that an Instance of Tomcat is already running on port 8080.

在我的情况下，查看服务器窗口只显示我从未用于该项目的 tomcat 服务器。我的 SpringBoot 项目使用了嵌入式 tomcat 服务器，当我的应用程序完成时它并没有停止。我用红色箭头指示的这个按钮将停止应用程序和 Tomcat 服务器，所以下次我运行应用程序时，我不会收到 Tomcat 实例已经在端口 8080 上运行的错误。

actual error messages:

实际错误信息：

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.

Caused by: java.net.BindException: Address already in use Caused by: org.apache.catalina.LifecycleException: service.getName(): "Tomcat"; Protocol handler start failed

验证连接器的配置，识别并停止侦听端口 8080 的任何进程，或将此应用程序配置为侦听另一个端口。

引起：java.net.BindException：地址已经在使用引起：org.apache.catalina.LifecycleException：service.getName()：“Tomcat”；协议处理程序启动失败

I will now be looking into a way to shut down all services on completion of my SpringBoot Consuming Rest application in this tutorial https://spring.io/guides/gs/consuming-rest/

I resolved this problem, by stop the application(red square in Eclipse) before run again. If you don't stop it , the application stay in run mode , so port still used .

我通过在再次运行之前停止应用程序（Eclipse 中的红色方块）解决了这个问题。如果您不停止它，应用程序将停留在运行模式，因此端口仍在使用。

first, check that who uses port 8080.

首先，检查谁使用了 8080 端口。

• telnet localhost 8080
• use browser to open http://localhost:8080

• telnet 本地主机 8080
• 使用浏览器打开http://localhost:8080

if the port 8080 is in use, change the listening port to 8181.

如果8080端口正在使用，请将监听端口更改为8181。

if you use IDEA, modify start configuration, Run-> Edit Configuration enter image description here

如果你使用IDEA，修改启动配置，运行->编辑配置 在这里输入图片描述

if you use mvn spring-boot, then use the command:

如果您使用 mvn spring-boot，则使用以下命令：

mvn spring-boot:run -Dserver.port=8181

if you use java -jar, then use the command:

如果使用 java -jar，则使用以下命令：

java -jar xxxx.jar --server.port=8181

In my case, Oracle TNS Service was using port 8080, found that using running the command "netstat - anob" as an administrator. Simply used Shutdown Database from the Windows start menu to stop that service and was able to start the SpringBoot app without any issue.

就我而言，Oracle TNS 服务使用端口 8080，发现使用以管理员身份运行命令“netstat - anob”。只需使用 Windows 开始菜单中的关闭数据库即可停止该服务，并且能够毫无问题地启动 SpringBoot 应用程序。

Also if you cannot find out which app is using the 8080 port and just want to run the SprintBoot app, you can click on Run As... and in the VM arguments enter: -Dserver.port=0 (this will pick any random available port) or you can be specific like: -Dserver.port=8081

此外，如果您无法找出哪个应用程序正在使用 8080 端口而只想运行 SprintBoot 应用程序，您可以单击 Run As... 并在 VM 参数中输入：-Dserver.port=0（这将选择任何随机可用端口）或者您可以具体如下：-Dserver.port=8081

Hope it helps.

希望能帮助到你。
