But when I try to run the server with the recommended command:

但是当我尝试使用推荐的命令运行服务器时：

./mvnw spring-boot:run

I get the following output:

如您所见，有一行是这样写的：

The Tomcat connector configured to listen on port 8080 failed to start. 

Any idea on how to make the server work?

关于如何使服务器工作的任何想法？

Thanks!

谢谢！

It says "BindException: Address already in use: bind", you must already be running some application under port 8080. Try to terminate that server and start again, or use a different port for this application, like 8081. If you can't check which app is using port 8080 already, use the following command

它说“BindException: Address already in use: bind”，你一定已经在端口 8080 下运行了一些应用程序。尝试终止该服务器并重新启动，或为此应用程序使用不同的端口，如 8081。如果你不能检查哪个应用程序已经在使用端口 8080，使用以下命令

netstat -anob 

You can now check and kill the application through task manager, assuming you're on windows.

假设您在 Windows 上，您现在可以通过任务管理器检查和终止应用程序。

回答by Praveen Sinha

It says 'Bind Exception', means the port 8080 is already having a connection. You can simply get a new free socket, use bind() on the port you are using, The OS will simply pick an unused port. simply create the application.properties file and put server.port=(newport);

它说“绑定异常”，意味着端口 8080 已经有连接。您可以简单地获得一个新的空闲套接字，在您使用的端口上使用 bind()，操作系统将简单地选择一个未使用的端口。只需创建 application.properties 文件并放置 server.port=(newport);

回答by Shivam.Garg

It says "BindException: Address already in use. Check below command to see if port is in use: lsof -i:8080And then kill the process using: Kill -9

它说“BindException：地址已在使用中。检查下面的命令以查看端口是否正在使用中：lsof -i:8080然后使用以下命令 终止进程：Kill -9

Alternatively you can use another port.

或者，您可以使用另一个端口。

回答by Tidlee

Use other than 8080 port. Add server.port=port number, for example server.port = 8085 in application.properties file, from src/main/resources directory.

使用 8080 端口以外的端口。在 src/main/resources 目录下的 application.properties 文件中添加 server.port=port 号，例如 server.port = 8085。

I recently had this port in useissue with Spring Boot 5.1.8.RELEASEwhich was using Tomcat 9.0.26

我最近有这个端口正在使用的问题，Spring Boot 5.1.8.RELEASE它正在使用Tomcat 9.0.26

The project ran perfectly fine in Eclipse STS but would not run on the CLI once built (using Maven). I tried using a whole bunch of different ports to no avail. Same issue every time.

该项目在 Eclipse STS 中运行良好，但一旦构建（使用 Maven）就无法在 CLI 上运行。我尝试使用一大堆不同的端口但无济于事。每次都是一样的问题。

I did 2 things

我做了两件事

1) Made sure the Packaging was set to war(not jar) - I am using JSP/JSTL for my pages, you might not need to do this yourself.

1) 确保将 Packaging 设置为war(not jar) - 我正在为我的页面使用 JSP/JSTL，您可能不需要自己执行此操作。

2) Updated the Tomcat version to 9.0.27as suggested in this SO post: Spring boot 2 embed tomcat 9.0.26 can not load jks file stream closedIt seems there is a bug in the version of Tomcat that was being used - 9.0.26

2）按照此SO帖子中的建议将Tomcat版本更新为9.0.27：Spring boot 2 embed tomcat 9.0.26 can not load jks file stream closed它似乎正在使用的Tomcat版本中存在错误 - 9.0。 26

I was getting the port in use message from Spring Boot but this was a red-herring.

我从 Spring Boot 获取端口正在使用消息，但这是一个红鲱鱼。

I looked up the Exception trace and it seemed to bomb out during the SSL configuration. A quick google took me to the post mentioned above.

我查找了异常跟踪，它似乎在 SSL 配置期间爆炸了。一个快速的谷歌把我带到了上面提到的帖子。

I tried it and it worked first time.

我试过了，第一次成功了。

The other answers on here are absolutely correct regarding the port being checked/changed. I just hope this answer might help someone who has checked their port usage like I did.

关于正在检查/更改的端口，此处的其他答案是绝对正确的。我只是希望这个答案可以帮助像我一样检查端口使用情况的人。

In Windows CMD you can find the Process-idof a running process on a specific port with:

在 Windows CMD 中，您可以使用以下命令找到特定端口上正在运行的进程的进程 ID：

netstat /nao | findstr "8080"

netstat /nao | findstr "8080"

Then you can kill this process with:

然后您可以使用以下命令终止此进程：

taskkill /pid Process-id/f

taskkill /pid 进程ID/f
