線程「主」異常java.net.BindException：地址已在使用

Question

我嘗試在我的linux服務器上安裝java HTTP API。我嘗試從命令pompt執行此命令來運行服務：

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 

然後，我有這樣的錯誤：

Exception in thread "main" java.net.BindException: Address already in use at sun.nio.ch.Net.bind0(Native Method) at sun.nio.ch.Net.bind(Net.java:463) at sun.nio.ch.Net.bind(Net.java:455) at sun.nio.ch.ServerSocketChannelImpl.bind(ServerSocketChannelImpl.java:223) at sun.nio.ch.ServerSocketAdaptor.bind(ServerSocketAdaptor.java:74) at sun.net.httpserver.ServerImpl.(ServerImpl.java:100) at sun.net.httpserver.HttpServerImpl.(HttpServerImpl.java:50) at sun.net.httpserver.DefaultHttpServerProvider.createHttpServer(DefaultHttpServerProvider.java:35) at com.sun.net.httpserver.HttpServer.create(HttpServer.java:129) at ExampleProgram.main(ExampleProgram.java:37)

這裏是ExampleProgram.java：

import java.io.IOException;

class ExampleProgram { 

public static void main(String[] args) throws Exception { 

EveryDetector evr = new EveryDetector(); 
InetSocketAddress addr = new InetSocketAddress("localhost",8080); 
HttpServer server = HttpServer.create(addr, 0); 

MyHandler hndl = new MyHandler(); 
hndl.setDetector(evr); 

MyHandlerExtractContent hnd2 = new MyHandlerExtractContent(); 
hnd2.setDetector(evr); 

MyHandlerDetectLanguage hnd3 = new MyHandlerDetectLanguage(); 
hnd3.setDetector(evr); 

server.createContext("/",hndl); 
server.createContext("/extractcontent",hnd2); 
server.createContext("/detectlanguage",hnd3); 
server.setExecutor(Executors.newCachedThreadPool()); 
server.start(); 
System.out.println("Server is listening on port 8080"); 


} 
}

出了什麼問題？我該如何解決它？

看起來像是正在發生的事情是，如果您更改端口號，您的問題應該消失，已經在端口8080上運行。
