我是 Spring Boot 的新手，所以我不知道如何解决这个问题。请建议我如何解决它？

我可以知道这个问题的问题。

提前致谢。

Answer 1

java.net.BindException: Address already in use: bind

表示您服务器的端口 (8080) 已在使用中。 确保您的网络服务器不再从以前的任何启动开始运行。

还要检查是否有任何其他应用程序在该端口上运行。 尝试打开http://localhost:8080/以获取在那里运行的提示。

Answer 2

转到任务管理器 -> 处理并结束 Java(TM) Platform SE 二进制进程（这将停止 tomcat）并再次运行您的 Spring Boot 应用程序。

Answer 3

在运行您的 Spring Boot 应用程序之前，请单击如上所示的红色“停止”按钮，首先停止服务器运行，以便可以重新使用该端口。 然后运行你的 Spring Boot 应用程序。

希望有帮助！

Answer 4

面临同样的问题。 您实际上可以通过在 src/main/resources 下包含 application.properties 来覆盖 tomcat 端口

application.properties 文件可能看起来像

server.port = 8443
#below lines for SSL
#server.ssl.key-store = classpath:sample.jks
#server.ssl.key-store-password = secret
#server.ssl.key-password = password

问候，

Answer 5

按照步骤杀死端口上的进程

1]在命令行界面

netstat -aon | find /i "listening"

2] 找到端口 8080 Ctrl+F 并输入 8080（要杀死的进程的端口号）

3]杀死它的关联进程ID。

Taskkill /PID 进程号 /F

Taskkill /PID 3440 /F

并重新运行程序

参考资料：列出进程， 杀死进程

Answer 6

使用使用的端口运行命令：示例： lsof -i : 8080(Port number)

现在杀死进程。 命令 -： kill -9 <PID> （例如： kill -9 8080 ）。

Answer 7

似乎已经有服务使用此端口，因此您可以找到此服务并停止它，或者您可以更改您的应用程序以通过以下方式侦听另一个端口

server.port=8081 # for example

在application.properties文件中

Answer 8

Spring Boot 使用端口 8080 作为内置 Apache Tomcat 容器的默认端口。 我们可以通过多种方式覆盖它。 下面给出了一种以编程方式进行操作的方式。

创建此组件。 并编译并运行您的应用程序。 根据要求更改端口。

@Component
public class CustomizationBean implements EmbeddedServletContainerCustomizer {
    @Override
    public void customize(ConfigurableEmbeddedServletContainer container) {
        container.setPort(8085);
        // Use port of your choice that is available
    }
}

Answer 9

如果你想运行同一个应用程序的 2 个实例，首先检查两者的端口配置是否不同，然后确保你用来运行它的插件没有检查文件中的更改并重新加载你的第一个实例，因为什么可能发生的情况是，当您更改第二个实例的端口时，插件已经使用此端口重新启动第一个实例，因此当您运行第二个实例时，端口已经很忙。

Answer 10

解决了！ 我也遇到过这个问题。 它有很多原因导致两个实例在同一端口上运行。 并检查jsp中表达式语言的属性是否与控制器模型属性匹配。 还要检查请求映射是否正确。 在我的情况下，只缺少“/”符号，这就是它抛出此错误的原因。

Answer 11

使用以下命令检查正在运行的处理。 netstat -ano | 查找字符串：

如果在以下命令中找到任何结果，则使用以下命令终止进程。

taskkill /PID /F注意：/F 用于强制杀死进程

Answer 12

今天我遇到了同样的错误，昨天一切正常。

问题是我在文件resources\\application.properties 中有以下代码行：

server.address=10.202.133.23
server.port=8080

并且IP变了。 所以，我在 ipconfig (cmd) 中实现了一个新的 IP，因为 DHCP 服务。 我更改了 server.address：

server.address=10.202.133.**24**
server.port=8080

瞧！
