eclipse - Tomcat 以 java.net.BindException : Address already in use exception 开头

Question

在此先感谢您的帮助!

我查看了 stackoverflow 上的所有相关帖子，但没有一个回答我的问题。

上下文:

Windows 10、Eclipse Neon.1 Release (4.6.1)，支持 Tomcat 和 Java 1。所有这些都在运行 MacOS Sierra 10.12.1 的 MacBook Pro 上运行，Parallels Desktop 12 for Mac Pro Edition 12.1.0 虚拟Windows 10。

当我启动 Eclipse 时一切正常。

当我单击 Eclipse Tomcat 启动按钮时，出现以下异常:

等等

我使用 TCPView 查找在端口 8080 上运行的程序并查看:

javaw.exe   1676    TCP TerryWin10onMac 8080    TerryWin10onMac 0   LISTENING                                       
javaw.exe   1676    TCPV6   terrywin10onmac.quantechsoftware.local  8080    terrywin10onmac.quantechsoftware.local  0   LISTENING                                       

所以是 Java，大概是 Tomcat 两次抢占了 8080 端口。

我停止 Tomcat，关闭 Eclipse，然后看到 TCPView 中对端口 8080 的所有引用都消失了。

我启动 Eclipse。 TCPView 仍然没有显示对端口 8080 的引用。

我启动 Tomcat 并看到一大堆东西出现在 TCPView 中，其中两个指向端口 8009，两个指向 8080:

javaw.exe 7076  TCP TerryWin10onMac 8005  TerryWin10onMac 0 LISTENING                   
javaw.exe 7076  TCP TerryWin10onMac 8009  TerryWin10onMac 0 LISTENING                   
javaw.exe 7076  TCPV6 terrywin10onmac.quantechsoftware.local  8009  terrywin10onmac.quantechsoftware.local  0 LISTENING                   
javaw.exe 7076  TCP TerryWin10onMac 8080  TerryWin10onMac 0 LISTENING                   
javaw.exe 7076  TCPV6 terrywin10onmac.quantechsoftware.local  8080  terrywin10onmac.quantechsoftware.local  0 LISTENING                   
javaw.exe 7076  TCP TerryWin10onMac 8443  TerryWin10onMac 0 LISTENING                   
javaw.exe 7076  TCPV6 terrywin10onmac.quantechsoftware.local  8443  terrywin10onmac.quantechsoftware.local  0 LISTENING                   

当然，所有的异常(exception)情况都和以前一样。

我试图杀死其中一个 8080 进程，但它们都有相同的进程 ID!事实上，上面显示的所有端口监听器都具有相同的 PID。

我不能更改端口。

如有任何帮助，我们将不胜感激。

非常感谢，

+1 以获得对您的研究的详细描述。

我建议您查看 <tomcat_home>\conf\server.xml文件并检查声明的所有端口。可能8080重复了。

并在 Eclipse 的服务器配置中执行相同的检查:看到没有重复的端口号。
