Question

我刚刚下载了这个项目：

https://github.com/oktadeveloper/okta-spring-boot-2-angular-5-example

对此教程进行了解释：

https://developer.okta.com/blog/2017/12/04/basic-crud-angular-and-spring-boot

但是当我尝试使用推荐的命令运行服务器时：

./mvnw spring-boot:run

我得到以下输出：

如您所见，一行显示：

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

关于如何使服务器正常工作的任何想法？

谢谢！

Answer 1

它显示“ BindException：地址已在使用中：bind”，您必须已经在端口8080下运行了某些应用程序。尝试终止该服务器并重新启动，或为此应用程序使用其他端口，例如8081。无法检查哪个应用已在使用端口8080，请使用以下命令

netstat -anob

现在，假设您在Windows上，则可以通过任务管理器检查并杀死应用程序。

Answer 2

显示“ BindException：地址已在使用中。检查以下命令以查看端口是否正在使用： lsof -i:8080 然后使用以下命令终止该进程：杀死-9

或者，您可以使用其他端口。

Answer 3

使用非8080端口。从src / main / resources目录中添加server.port =端口号，例如application.properties文件中的server.port = 8085。

Answer 4

我最近在使用Spring Boot 5.1.8.RELEASE

的Tomcat 9.0.26中遇到了这个 port 问题

该项目在Eclipse STS中运行良好，但是一旦构建（使用Maven）就无法在CLI上运行。我尝试使用一大堆不同的端口都无济于事。每次都一样。

我做了两件事

1）确保“包装”设置为war（不是jar）-我的页面使用的是JSP / JSTL，您可能不需要自己做。

2）按照本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 似乎正在使用的Tomcat版本中存在一个错误-9.0.26

我从Spring Boot收到了端口正在使用的消息，但这是一条红色的鲱鱼。

我查找了异常跟踪，它似乎在SSL配置期间被炸毁。一个快速的谷歌带我到上述职位。

我尝试过，它第一次起作用。

关于被检查/更改的端口，此处的其他答案绝对正确。我只是希望这个答案可以对像我一样检查过端口使用情况的人有所帮助。

Answer 5

在Windows CMD中，您可以找到正在运行的进程ID 在特定端口上执行以下操作：

netstat / nao | findstr“ 8080”

然后您可以使用以下方法终止此过程：

taskkill / pid 进程ID / f

Answer 6

它显示“绑定异常”，表示端口8080已建立连接。您可以简单地获得一个新的空闲套接字，在使用的端口上使用bind（），操作系统将只选择一个未使用的端口。

配置为侦听端口8080的Tomcat连接器无法启动

6 个答案:
