线程"main"中的异常java.net.BindException:地址已在使用中 [英] Exception in thread "main" java.net.BindException: Address already in use

问题描述

我尝试在Linux服务器上安装Java HTTP API.我尝试从命令提示符执行以下命令以运行服务:

I try to install a java HTTP API on my linux server. I try to execute this command from command pompt to run the service:

java -Dfile.encoding=UTF8 -cp .:boilerpipe-1.2.0.jar:lib/nekohtml-1.9.13.jar:lib/xerces-2.9.1.jar:lib/langdetect.jar:lib/jsonic-1.2.8.jar ExampleProgram

然后我出现此错误:

线程"main"中的异常java.net.BindException:地址已在使用中 在sun.nio.ch.Net.bind0(本机方法) 在sun.nio.ch.Net.bind(Net.java:463) 在sun.nio.ch.Net.bind(Net.java:455) 在sun.nio.ch.ServerSocketChannelImpl.bind(ServerSocketChannelImpl.java:223) 在sun.nio.ch.ServerSocketAdaptor.bind(ServerSocketAdaptor.java:74) 在sun.net.httpserver.ServerImpl.(ServerImpl.java:100) 在sun.net.httpserver.HttpServerImpl.(HttpServerImpl.java:50) 在sun.net.httpserver.DefaultHttpServerProvider.createHttpServer(DefaultHttpServerProvider.java:35) 在com.sun.net.httpserver.HttpServer.create(HttpServer.java:129) 在ExampleProgram.main(ExampleProgram.java:37)

这是ExampleProgram.java:

System.out.println("Server is listening on port 8080" );


 }
}

怎么了?我该如何解决?

What is wrong? How can I fix it?

推荐答案

正在发生的情况是，如果更改端口号，则8080端口上已经在运行某些东西，那么问题就应该消除了.

What looks like is happening is that something is already running on port 8080 if you change the port number your problem should go away.
